The aim of this work was to investigate the genotypic variation of thirty five bread wheat genotypes as well as to clarify the association between grain yield and the other important agronomic traits. Two field experiments were carried out in the Experimental Farm of Genetic Resources Department, Bahteem Agricultural Research Station, Egypt during 2015-2016 and 2016-2017 growing seasons. Thirty two wheat landraces collected from eleven Districts in Egypt, in addition to three local cultivars were evaluated for earliness traits, plant height, yield and its components. The results indicated significant differences among the evaluated wheat genotypes for all investigated traits during the two seasons. The highest grain weight/plant and contributing traits were assigned for genotypes; G3, G8, G18, G27, G29, G33 and G35 at two growing seasons. The phenotypic variance (σ2ph) was found slightly higher than the genotypic variance (σ2g) for all studied traits under two seasons, and accordingly, phenotypic coefficient of variation (PCV) values were relatively greater than genotypic coefficient of variation (GCV) values for all traits. Heritability in broad sense (h2b) values were high for plant height (90.63 and 97.81 %), number of grains/spike (95.33 and 84.66 %), 1000-grain weight (76.42 and 84.03 %), days to heading (77.4 and 87.06 %) and days to maturity (86.18 and 66.56 %) in 1st and 2nd seasons, respectively. Besides, it was low in 1st season (43.38 %) and high in 2nd season (71.91 %) for grain weight/plant, whereas it was moderate for number of spikes/plant (52.87 and 58.09 %) in 1st and 2nd seasons, respectively. Furthermore, positive genotypic and phenotypic correlations were found between studied traits and grain weight/plant during two growing seasons except days to heading. Additionally, path analysis was calculated and it was found that the direct effects on wheat grain yield of all studied traits were positive in both seasons except days to 50% heading at two seasons and days to maturity and plant height at the second season.

This investigation aimed to study mean performance, genotypic variances, types of gene action and heritability for earliness, yield and components in four bread wheat crosses using six populations i.e. (P1, P2, F1, F2, BC1 and BC2) under different thermal conditions. Wheat crosses populations were sown on 19th November and 3rd January at the Experimental Farm, Faculty of Agriculture, Zagazig University, Egypt in a randomized complete block design in 2017/2018 season. Scaling test provide evidence of non-allelic interaction in controlling all studied characters in the four crosses on both sowing dates except No. of spiklets/spike in the 3rd and 4th crosses and grain yield/plant in the 2nd and 3rd crosses on normal sowing date, indicated the presence of epistasis and the digenic model proved to be satisfactory in explaining the inheritance of the previous characters in the corresponding crosses. Narrow-sense heritability estimates recorded high values (>50%) for days to heading in the 1st and 2nd crosses on normal sowing date and the 3rd cross on both sowing dates; days to maturity in the 1st and 4th on normal sowing date and the 3rd cross on both sowing dates, No. of tillers/plant in the 3rd cross on both sowing dates and the 2nd and 4th crosses on normal sowing date; No. of spiklets/spike in all crosses on both sowing dates except the 1st and 2nd crosses on normal sowing date; No. of grains/spike in the 2nd cross on both sowing dates, the 4th cross on normal sowing and the 1st cross on late sowing date; weight of grains/spike in the 2nd cross on both sowing dates and the 3rd on normal sowing date, 1st and 4th crosses on late sowing date and grain yield/plant in the 1st cross on both sowing dates and the 3rd and 4th crosses on late sowing date.

Two field experiments were carried out in the Agricultural Research Station, Faculty of Agriculture, Zagazig University, El-Khattara Region, Sharkia Governorate, Egypt, during the two winter seasons of 2015/2016 and 2016/2017 to find out the response of faba bean (improved Giza 3 cv.) to three planting densities (80000, 100000 and 120000 plants/fad.), three humic acid rates (zero, 2 and 4 kg humic acid/fad.) and four phosphorus levels (zero, 15.5, 31 and 46.5 kg P2O5/fad.). The results of the combined analysis revealed that increasing planting density significantly decreased number of pods and branches/plant, and seed weight/plant as well as protein yield/fad., while, plant height and biological yield/fad., were significantly increased by increasing plant densities up to 120000 plants/fad. The highest value of seed yield/fad., was obtained by planting faba bean on density 100000 plants/fad. Results of the combined analysis also showed that, increasing humic acid rates up to 4 kg/fad., significantly increased number of pods/plant, weight of seeds/plant and protein yield/fad., but, hundred seed weight, plant height and number of branches/plant were not affected by the application of humic acid. Meanwhile, biological and seed yields/fad., were responded to the application of humic acid rate up to 2 kg/fad. In general, application of phosphorus fertilizer up to 46.5 kg P2O5/fad., significantly increased all traits under study such as number of branches and pods/plant, weight of seeds/plant, seed and biological yields/fad., and protein yield/fad as compared to other rates (combined data), while, hundred seed weight significantly increased by increasing P levels up to 31 kg P2O5/fad. Interaction results showed that, faba bean plants received 31 kg P2O5/fad., and 2 kg humic acid/fad., or received 2 kg humic acid under medium density (100000 plants/fad.) produced the highest value of seed yield/fad.

Stability is important indicator in light of climate change in the Mediterranean region. Therefore, thirteen bread wheat genotypes were evaluated for grain yield under eight different environments. The environments were the combinations of four irrigation regimes (normal, mild, moderate and severe stress) × two seasons (2016/2017 and 2017/2018). Results indicated that stability analysis of variance revealed highly significant G x E “linear” for grain yield. Phenotypic stability parameters showed that wheat genotypes Gemmeiza12 and Line 3 were highly adapted to improved environments. On the contrary, wheat genotypes Sakha 95, Line 142 and Line 1 were adapted to water stress environments. Furthermore, wheat genotypes which could be grown under a wide range of environments were Misr 1, Misr 2, Sakha 94, Giza 171, Shandweel 1, Line 26 and Line 6 for grain yield. The most desired and stable genotypes were Misr 1, and Gemmeiza 11 for grain yield. The additive main effect and multiplicative interaction (AMMI) analysis of variance showed that 49.56, 28.90 and 1.79% of the total sum of squares were attributable to environmental, genotypic and genotype x environment interaction (GEI) effects for grain yield, respectively. Both models of Eberhart and Russell (1966) and AMMI (Gauch, 1992) are consistent in describing the stability of Misr 1 and Gemmeiza 11 for grain yield. These genotypes could be useful in wheat improvement programs for enhancing stability.

A field experiment was conducted at the summer season of 2017, and then repeated at the summer season of 2018 in Agricultural Research Station. Faculty of Agric., Zigzag Univ., Sharkia Governorate, Egypt. The study investigated the impact of eleven nitrogen and five phosphorus fertilization regimes on some leaf traits 70 days after sowing (DAS) of maize cultivar single hybrid 168. Results showed that, 120kg N/fad., from different sources i.e., chemical fertilizer, compost and biofertilizers were effectless on number of leaves/plant at 70 days after sowing (DAS) of both seasons and their combined analysis. Number of leaves either under or above the ear of mono eared maize plant were not affected due to applying different nitrogen fertilization regimes studied. Leaf area/maize plant was significantly affected in the first season only. The largest leaf erea/plant (4254.22 cm2/plant) was obtained in the first season, with the appliance of the integrated N fertilization regime (90 kg N from chemical fertilizer +30 kg N from compost). Area of leaves under ear resulted from the integrated fertilization regime (cerealine + 60 kg chemical N+ 60 kg N from compost) was larger than that in the control treatment by 30.94% based on combined results. Regarding to the area of leaves above the ear, results of the 1st season displayed that area of leaves above the ear were at par in treatments N2, N3, N4, N5 and N6. Application of either 120kg chemical fertilizer (N2) or 90 kg chemical N +30 kg N from compost (N3) was conjucated with larger values of leaf area index comparably with other regimes. According to combined analysis, ear leaf area ranged from 481.87 cm2 in control treatment to 625.89 cm2 in the integrated nitrogen fertilization regimes comprised of cerealine + 60 kg chemical N/fad. + 60 kgN from compost. From the results of combined analysis, it could be noted that tassel leaf area ranged between 150.99 to 217.87 cm2 under biofertilization (N11) and the integrated fertilization regimes (N8)in the same order. Insignificant phosphorus fertilization effect under study on maize leaf traits studied at 70DAS, was recorded in both seasons and the combined analysis.

In order to determine performance, gene action and heritability for earliness, yield and chocolate spot disease of faba bean, a half diallel crosses among six parental genotypes were evaluated under control and artificial infection by chocolate spot disease (Botrytis fabae sard). The results indicated highly significant differences among faba bean genotypes for all the studied characters under these conditions. All faba bean genotypes under study appeared to be high resistant or resistant for chocolate spot disease with a few exception under different conditions. Whereas, genotypes Misr 3, Wadi 1, Sakha 4 x Misr 3, Sakha 4 x Nubaria 1, and Misr 3 x Wadi 1 under the natural infection conditions. However, Sakha 4, Nubaria 1, NA 112, Sakha 4 x Misr 3, Sakha 4 x NA 112, Misr 3 x Wadi 1, Nubaria 1 x T.W, Wadi 1 x NA 112 and T.W x NA 112 under the artificial infection were less resistant or susceptible to chocolate spot disease. The results revealed that additive (D) and dominance (H1 and H2) appeared to be significant for days to flowering and maturity, chlorophyll content (SPAD), seed weight/plant and resistance to chocolate spot under both conditions. The additive genetic component was higher in its magnitude as compared to the dominance ones for resistance to chocolate spot under the natural infection condition, resulting in average degree of dominance (H1/D)0.5 less than the unity. Whereas, dominance component (H1 and H2) made up the most part of the total genetic variation as it was larger in its magnitude than the corresponding additive one for earliness characters, chlorophyll content and seed weight/plant under both conditions and resistance to chocolate spot under the artificial infection only. Thus, the average degree (H1/D) 0.5 was more than the unity for these characters. Narrow sense heritability (h2n) was moderate (39.1%) to low (20.4%) for seed weight/plant and high (65.1%) to moderate (45.0%) for chocolate spot disease under control, natural infection and artificial infection of chocolate spot disease, respectively.

Two field experiments were conducted during two consecutive summer seasons of 2014 and 2015 in an administrative field at Diarb Negm District, Sharkia Governorate, under Agronomy Department supervision, Faculty of Agriculture, Zagazig University, Egypt. The aim of this study was to investigate the response of two yellow maize hybrids (Single Cross 176 and Three-way Cross 352) to three plant densities (20000, 24000 and 30000 plants/fad.), and nitrogen-farmyard combination fertilizer levels (60, 80 and100 kg N/fad., without addition of farmyard manure (FYM) and 60 kg N/fad.+20 m3 FYM/fad., 80 kg N/fad.+ 20 m3 FYM/fad., and 100 kg N/fad.+20 m3 FYM/ fad.) under clay soils conditions. The obtained results could be summarized as follows: The tried three maize plant densities had different effects on plant height (cm), ear diameter and length (cm), number of rows/ear, number of kernels/row, 100-kernel weight, kernel weight/ear, and biological yield (ton/fad.) during both seasons and their combined analysis, but the differences among the tried three maize plant densities on aforementioned traits did not reach the level of significance. Results of the first season and the combined analysis detected significant differences among the tried plant densities on ear yield/fad. Where, ear yield/fad., and grain yield/fad., in the first season and combined analysis, harvest index and grain: stover ratio in the two seasons and their combined analysis were significantly increased due to increasing maize density from 20000 or 24000 and up to 30000 plants/fad. Maize SC 173 cultivar appeared to produced taller plants, longer ears and larger number of kernels/row than TWC 352 cultivar. The later produced larger ear diameter, number of rows/ear, 100-kernel weight, kernel weight/ear, ear yield/fad., grain and biological yields/fad., than SC 173 one. No significant differences between two maize cultivars regarding harvest index and grain: stover ratio was observed. The first and the second increments in nitrogen levels up to 100 kg N/fad., with or without addition of farmyard manure was accompanied by a significant increase in ear diameter (cm), ear length (cm), number of rows/ear, number of kernels/row, 100-kernel weight (g), kernel weight/ear (g), ear yield/fad., grain and biological yields (ton/fad.) but harvest index and grain: stover ratio were reduced during both seasons and their combined analysis. These results finally recommend sowing maize cultivar TWC 352 with dense planting of 30000 plants/fad., and raising nitrogen level up to 80 kg N/fad., with addition of farmyard manure to maximize grain yield/fad., under the experimental site and other likely environmental condition.

This work was carried out in a Private Farm at Awlad Saqr District, Sharkia Governorate, Egypt during two successive summer seasons of 2016 and 2017 to study the effect of mineral fertilizers (NPK), organic fertilizer in the form of poultry manure (PM) and bio-fertilizer (Nitrobein, Phosphorein and Potassiumag) each alone and their mixture on dry weight parameters, flowering, fruit set and yield and its components of some tomato hybrids grown under high temperature conditions. The experimental design was split plots with three replicates included 14 treatments. Two different tomato hybrids were used included. Alia123 (V1) and Rama888 (V2)were randomly distributed in the main plots and 7 fertilization treatments [100%mineral fertilizers (T1), 100% bio-fertilizers (T2), 100% organic (T3), 100% mineral+100% organic manure + 100% bio-fertilizer (T4), 75% mineral + 100% organic manure + 100% bio-fertilizer (T5), 50% mineral + 100% organic manure + 100% bio-fertilizer (T6) and 25% mineral + 100% organic manure + 100% bio-fertilizer (T7)] were arranged in sub plots. Results showed that dry weight of shoots per plant and total dry in Alia123 (V1) hybrid significantly increased. While Rama888 hybrid (V2) significantly enhanced flowering, fruit set characters, as well as yield and its components. Moreover, 100% mineral + 100% organic manure + 100% bio-fertilizer (T4) significantly improved all dry weight parameters. Also the same treatment significantly increased flowering, fruit set characters and yield and its components. Furthermore, using Alia123 (V1) hybrid with mixture of 100% mineral + 100% organic fertilizer + 100% bio-fertilizer (T4) significantly enhanced all dry weight parameters. While using Rama 888 hybrid (V2) with a mixture of 100% mineral + 100% organic fertilizer + 100% bio-fertilizer (T4) were the superior interaction treatment which reflected a significant effect on all flowering and fruit set characters, as well as yield and its components. Generally the both hybrids were recorded good results for sowing under high temperature conditions in most cases.

This investigation was carried out at a Privet Farm, El-Ibrahimia District, Sharkia Governorate, Egypt during the two consecutive seasons of 2016/2017 and 2017/2018 to study the effect of different saline irrigation water levels (0.0, 10000, 15000 and 20000 ppm NaCl), amino acids type (0.0, proline at 200 ppm, putrescine at 200 ppm and proline + putrescence each one at 200 ppm) and their combinations on plant growth, root system, salt resistance index and leaf pigments content of seashore paspalum (Paspalum vaginatum, Swartz) turfgrass. Plastic pots in 35 cm diameter filled with 5.5 kg of sand and clay mixture (1:2, V/V) were used in this experiment. The obtained results showed that plant growth (plant height , covering density percentage and herb fresh and dry weights), root system (root fresh and dry weights and root length), salt resistance index and leaf pigments (chlorophyll a, chlorophyll b and carotenoids contents) were descendingly decreased with increasing salinity level of irrigation water comparing with the control in both seasons, but they were progressively increased as the concentration of amino acids (proline and putrescine) was used. From these results, it can be recommended to irrigate seashore paspalum turfgrass with saline water up to 10000 ppm NaCl and sprayed with proline + putrescine each at 200 ppm to obtain the best growth, colour and higher covering density.

Two pot experiments were carried out at Ornamental Nursery, Faculty of Agriculture, Zagazig University, Egypt, during the two consecutive seasons of 2016/2017 and 2017/2018 to study the effect of different saline irrigation water levels (0.0, 1000, 2000 and 3000 ppm), proline concentrations (0.0, 100 and 200 ppm) and their combinations on plant growth, salt resistance index, volatile oil production, photosynthetic pigments and proline content of sweet basil (Ocimum basilicum, L) plant.Plastic pots in 40 cm diameter filled with 6 kg clay soil were used in this experiment. This experiment was set up in a split-plot design with three replicates. The main plots were occupied by saline water levels and the sub plots were entitled to proline concentrations.The results showed a significant decrease in most studied plant growth parameters (plant height, number of branches/plant and herb and root dry weight/plant), salt resistance index, volatile oil production (volatile oil percentage and volatile oil yield/plant) and photosynthetic pigments (Chlorophyll a and chlorophyll b) with increasing the levels of salinity, but an opposite impact occurred with increasing the proline concentrations. Also, proline content was decreased as increasing the levels of salinity to reach the maximum values with 3000 ppm salinity level. However, for the combination among the levels of saline water and proline, the combination treatment (1000 ppm salinity level + 100 ppm proline) showed the highest increment in the growth and productivity of sweet basil plant under Sharkia Governorate conditions.

Field experiments were conducted to evaluate the effect of three insecticides individually and in combination with two adjuvants (Tween 80 and Sylgard 309) for control of the wheat aphid, Schizaphis graminum and onion thrips, Thrips tabaci on wheat plants during two successive growing seasons 2016 and 2017. The three tested insecticides were lambda- cyhalothrin 5% EC at the rate of 100 ml/100 l , thiamethoxam 25% WG at the rate of 20 g/100 l and malathion 57% EC at the rate of 150 ml/100 l. Twelve treatments (11 insecticides and their mixtures with adjuvants + control) were replicated four times in a completely randomized design. Chemicals were sprayed using a knapsack sprayer motor in separated plots (1/100 faddan). Mean numbers of wheat aphids and onion thrips were recorded before spraying and post treatment periods of 1, 3, 7 and 10 days. Results showed that application of the tested insecticide lambda-cyhalothrin either individually or in combination with sylgard 309 or tween 80 resulted in a significant reduction in the number of the wheat aphid recording 100% mortality in all treatments as initial effect in both seasons 2016 and 2017. Based on general average, a clear effects of lambda-cyhalothrin with sylgard 309, lambda- cyhalothrin with tween 80 and lambda- cyhalothrin were the highly toxic and rapidly kill the tested aphid recording 96.73, 95.83 and 95.43% mortality, respectively, in season 2016 and 98.33, 98.12 and 97.35% mortality, respectively, in season 2017 followed by thiamethoxam and its mixtures then malathion with sylgard 309, malathion with tween 80 and malathion alone recording 86.30, 85.87 and 83.56% mortality, respectively, in season 2016 and 90.77, 90.63 and 88.60% mortality, respectively, in season 2017. After 1 day of spray, lambda-cyhalothrin recorded the most effective treatment resulting in 100% thrips reduction, the same result was recorded for lambda-cyhalothrin + sylgard 309 (100%) and lambda-cyhalothrin + tween 80 (100%). Thiamethoxam, malathion and their mixtures with the two adjuvants caused also 100% thrips reduction. Mortality percentage induced by sylgard 309 and tween 80 were only 56.67 and 49.58%, respectively during season 2016. Similar results were recorded after 24 hr. of application in the second season 2017. After 3, 7 and 10 days of treatments, lambda-cyhalothrin plus sylgard 309, lambda-cyhalothrin + tween 80 and lambda-cyhalothrin alone induced the highest percentages of mortality during seasons 2016 and 2017, respectively, which differed significantly than control. Moreover thiamethoxam with sylgard 309 was recorded 100, 92.77 and 87.40% thrips reduction after 3, 7 and 10 days from spray, respectively, during seasons 2017. However, the results showed also that malathion and its mixtures caused lower percent mortality than the other two tested insecticides and its mixtures during season 2016 and 2017. All the insecticides and their mixtures were significantly better than untreated check in reducing the tested pests population. Lambda- cyhalothrin proved the best effect followed by thiamethoxam and malathion.

Fusarium culmorum(W.G. Smith) Sacc., Bipolaris sorokiniana (Sacc.) Shoemaker, Rhizoctonia oryzae Kühn and Fusarium spp. were isolated from wheat plants exhibiting typical root and crown rot symptoms from different districts at Sharkia Governorate, Egypt during 2015/ 2016 growing season. Pathogenicity test revealed that B. sorokiniana was the most virulent one causing pre-emergence damping-off followed by Fusarium culmorum. In addition, F. culmorum was the most virulent one responsible for post-emergence damping-off incidence. Rhizoctonia oryzae showed the highest percentage of root rot, Moreover, F. culmorum and B. sorokiniana showed the highest percentage of disease incidence. In the same trend, F. culmorum induce the highest percentage of disease severity. In vitro, Trichoderma sp. bio-agent and its culture filtrate were the most effective treatment that reduced mycelial growth of the tested fungi. In vivo, it decreased pre and post-emergence damping off, root rot, disease incidence and disease severity compared with the control. In addition, the obtained results indicated a significant increase on healthy survival plants and significantly improved the plant growth parameters i.e. fresh and dry weights of shoots and roots, plant height, spike length and 1000 grain weight. In vitro,Score and Amistar-top fungicides were the most effective in inhibiting the mycelial growth of R. oryzae followed by Amistar-top on B. sorokinana and Score onF. culmorum.Score was the most effective treatment revealed the highest percentage of healthy survival plants followed by Amistar-top and gave the highest protection against root and crown rot disease as shown by disease incidence and severity percentages.

Seed-borne fungi cause several diseases of common bean (Phaseolus vulgaris L.) and soybean (Glycine max L.). The survey of seed-borne fungi of common bean and soybean was carried out on three Egyptian Governorates (Behera, Dakahlia, and Ismailia) in Egypt. Nineteen fungal species comprising therteen genera were isolated from the collected common bean and soybean seed samples, using standard blotter i,e. Alternaria alternata, Alternaria spp., Aspergillus niger, Aspergillus ochraceous, Aspergillus flavus, Botryodiplodia sp., Cladosporium sp., Colletotrichum lindemuthianum, Colletotrichum dematium, Fusarium solani, Fusarium moniliforme, Fusarum oxysporum, Macrophomina phaseolina, Myrothecium sp., Penicillium spp, Rhizoctonia solani, Stemphylium spp., Trichoderma spp. and Trichothecium sp. Pathogenicity tests proved that C. lindemuthianum and C. dematium were pathogenic to common bean and soybean. Polymerase chain reaction (PCR) has many beneficial characteristics that make it highly applicable for detecting Colletotrichum spp. of seeds. PCR diagnosis method and DNA extraction considered one of the most important steps and purity of DNA template for successful PCR assay. For the PCR amplification of C. lindemuthianum and C. dematium, two primers ClF4 and ClF5, stander blotter, agar plate, and deep freezing method were used as seed healthy testing methods. Stander blotter was proved the past and quickly method to detect seed-born of C. lindemuthianum and C. dematium. Trichoderma harzianum reduced linear growth for C. lindemuthianum and C. dematium followed by Trichoderma viride and Bacillus subtilis recording (3.3 cm and 3.9 cm, respectively) followed by Pseudomonas floursence that display a high linear growth (7.4 cm). On the other hand, fungicide Aetro 30% (Iprodione + Tebuconazole) recorded the least linear growth (0.9 cm) for C. lindemuthianum and C. dematium compared with negative control recorded (9.0 cm in diameter). Thymus plant extract caused the lowest liner growth (3.7 cm). Plant extract concentrations caused a significant reduction in the growth of C. lindemuthianum and C. dematium. The highest concentration (1.5 %) gave less fungal growth while the lowest one (0.5%) showed the highest fungal growth compared with negative control.

Biological experiment was conducted in the clay and sandy soils to study the effect of inorganic, organic and bio fertilization on growth and yield components as well as N, P and K- uptake by wheat plants. Ammonium sulphate (N) was added at the rates of 25 [50% the recommended dose (RD)] and 50 (100% RD) mg N kg-1 soil, while ordinary superphosphate (P1) and rock phosphate (P2) were applied at the rates of 9.72 (50% RD) and 19.44 (100% RD mg P kg-1 soil. Potassium sulphate (K1) and feldspar (K2) were added at the rates of 20.8 (50% RD) and 41.5 (100% RD) mg K kg-1 soil. The organic materials i.e. clover straw (CS), sunflower seed teflon (ST) and banana peel (BP) were added at a rate of (0.5%). Some wheat grains were inoculated by biofertilizers i.e. nitrobein (nit), phosphate dissolving bacteria (PDB) and potassiumage (Pot). The results showed that the treatments of [50% RD (NP1K1) + CS + ST + BP + Nit + PDB + Pot] gave the greatest values of the straw and grains dry weight, biological yield and harvest index, N-uptake by grains and P- and K- uptake by straw and grains if compared to the other treatments in both soils under study. Wherease the highest 1000 grains weight was observed with the treatment of [50% RD (NP2K2) + CS + ST + BP + Nit + PDB + Pot] in the clayey soil and [50% RD (NP1K1) + CS + ST + BP] in the sandy soil compared to the other treatments. The greatest values of N- uptake by straw were recorded with treatments of [50% RD (NP1K1) + CS + ST + BP] in the clayey soil and [50% RD (NP1K1) + CS + ST + BP + Nit + PDB + Pot] in the sandy soil compared to the other treatments. Finally, it could be concluded that the use of 50% of the recommend dose of the most mineral fertilizers (NP1K1) mixed with organic materials (CS + ST + BP) and biofertilizers (Nit + PDB + Pot) may reduce the mineral fertilization (NP1K1) dose, production cost and environmental contamination.

The objective of this study was to assess the quality of irrigation water, groundwater and drainage water in Mashtoul El-Souq District, Sharkia Governorate, for the supplemental irrigation purposes to compensate for the lacke of fresh irrigation water required for crops grown in the study area. Six sampels from Nabtit and El-Serw irrigation canals, 26-sampels from observation wells (groundwater) and 6-sampels from the outlets of main subsurface drainage collectors (drainage water) were collected during summer (2017) and winter (2017/2018). To achieve this study, three neighboring sites with already installed subsurface drainage system were selected. Three drainage collectors were choosen (one for each site). Five pizometers (observation wells) were constructed at the first collector, 4 pizometers at the second collector and 4 pizometers at the third collector. Water samples were periodically taken from the drainage network at the dumps of drainage pools in exchange rooms. Water samples were subjected to chemical analyses and then calculating some quality parameters to assess their validity for supplemental agricultural irrigation. Cations, anions, pH and EC were determined. Results showed that PH values ranged from7.6 to 8.0 in irrigation water samples, and the average of salinity (EC) and sodicity (SAR) values in irrigation water samples were 0.63 dSm-1 and 2.09, respectively, low saline and alkaline water which is good for irrigation. The pH values of the drainage water ranged from 7.8 to 8.2, and the average values of EC and SAR values in drainage water samples were 2.1 dSm-1 and 4.52, respectively. According to the division of the US Salinity Lab. (1954), it was classified as C2S1 for irrigation water samples, and for drainage water, the classification lies between C3S2 and C4S2. There were seasonal differences in the concentration of soluble ions. Salinity and sodicity of subsurface water varied from 0.78 to 3.12 dSm-1 and 1.75 to 8.42, respectively. A better strategy for dealing with the "disposal" of subsurface agricultural drainage water is that the drainage water could be intercepted, isolated from the good-quality water, and reused for the irrigation of suitably salt-tolerant crops other than blending.

This study was designed to evaluate some properties of fruit yoghurts made with adding carrot and guava pulp during storage. The obtained results revealed that, the pH was decreased by time of storage while acidity was increased in all types of drinking yoghurt. Adding of 10, 15 and 20% guava pulp in yoghurt increased significantly (p<0.05) the total phenolic compounds (TPC), antioxidant activity (AA), fiber content and ascorbic acid (Vitamin c). The rheological and sensory properties of yoghurt were improved comparing to the control samples, While the protein content, pH value and syneresis decreased significantly (p<0.05) than control samples. On the other hand, Addition of 10, 15 and 20% carrot pulp to yoghurt increased (TPC), (AA), ascorbic acid and fiber content, while the protein content, pH value decreased. Along the storage period of all treatments, the TS, acidity, synersis and viscosity increased significantly, while the pH value, ascorbic acid, acetaldehyde content, AA,TPC were decreased significantly.

Buttermilk has a potential to become a daily diet drink at global level due to its high nutritive value and ease of production process. In present study, novel buttermilk beverages were developed using barley and oat flour supplementations. Acidity, pH, viscosity, whey separation and sensory properties were studied. Supplementation with barley and oat flours (2 and 4% for both) showed changes in buttermilk acidity and pH. Whey separation was lower and viscosity was higher in buttermilk sample containing 4%barley and oat flours. Buttermilk samples were also evaluated for their sensory characteristics including colour and appearance, body and mouth feel, flavour and overall acceptability. Samples with 4% oat flours level obtained the highest scores in the sensory evaluation. The viscosity of the buttermilk samples increased proportionally with the levels of barley and oat flour supplementations. Oat flour supplementation at 4% level in buttermilk improved nutritive, physicochemical and desirable sensory characteristics more than barley flour.

This study was carried out to estimate the effect of adding pomegranate (Punica granatum L) and cactus pear (Opuntia ficus indica) juices as natural ingredients on physico-chemical characteristics, antioxidant activity, microbiological examination and sensory evaluation of stirred yoghurt. Stirred yoghurt was prepared by using cow, s milk 3% fat, and pomegranate and cactus pear juices were added at the rate of 5%, 10% and 15% W/W. All treatments were inoculated with 2% of yoghurt starter and stored at 5°C up to the end of storage period (15 days) after complete a sulation. Physico-chemical properties of yoghurt samples such as total solids, protein, fat, pH, syneresis, viscosity was carried out .Also, microbiological examination and sensory evaluation were determined of all the treatments when fresh ,and then after 5, 10 and 15 days of cold storage at 5°C. The results showed that significant differences were found between the control and stirred yoghurt fortified with juices in the total solids, protein content, pH and titratable acidity up to the end of storage period(15 days). Addition of pomegranate and cactus pear juices led to significant increase in phenolic compounds and antioxidant activity of yoghurt treatments compared with the control sample. In all samples, it was observed that the titratable acidity increased over the storage period. Low values for viscosity and high values for syneresis were belonged to yoghurt containing 15% pomegranate and cactus pear juices. Sensory evaluation results showed that there were significant differences among the yoghurt samples. Stirred yoghurt (control) and stirred yoghurt containing 5% cactus pear or pomegranate juices gained significantly highest flavour and texture scores compared to stirred yoghurt treated with 10% or 15% juices. The results of current study demonstrated that the addition of juices from pomegranate and cactus pear to stirred yoghurt milk, significantly improved the quality of yoghurt and will increase its healthy benefits.

The present study demonstrates a positive correlation between zinc metal tolerance ability of an isolated fungi and their potential for the synthesis of zinc oxide nanoparticles (ZnO-NPs). A total of 5 fungal cultures were isolated from the rhizospheric soils of plants naturally growing at Sharkia Governorate in Egypt and identified based on morphological characteristics. These isolates are belongs to Aspergillus niger (An), Aspergillus tubulin (At), Aspergillus fumigatus(Af), Penicillium citrinum (Pc) and Fusarium oxysporum (Fo). These isolates were usedin the synthesis of zinc-oxide nanoparticles (An-ZnO-NPs, At-ZnO-NPs, Af-ZnO-NPs, Pc- ZnO-NPs and Fo- ZnO-NPs) using Zinc sulfate as the precursor compared to the references strains of A. tubingensis Mosseray AUMC No.6915, A. fumigatus Fresenius AUMC No.48and A. terreus Thom AUMC No.75. Aspergillus and Fusarium isolates have been shown to have a high zinc metal tolerance ability and a potential for extracellular synthesis of ZnO nanoparticles under ambient conditions. The synthesized ZnO-NPs were tested by the detection of a notable absorption peak at 285 to 296 nm, appearing in UV–Vis spectra due to surface-plasmon-resonance. Transmission electron microscope (TEM) results revealed that An-ZnO-NPs, At-ZnO-NPs, Af-ZnO-NPs, Pc- ZnO-NPs and Fo- ZnO-NPs exhibited a crystalline structure with hexagonal wurtzite shape (30–100 nm size). ZnO nanoparticles exhibited excellent antibacterial activity against tested Gram-positive and Gram-negative bacteria. The ZnO nanoparticles showed better antibacterial activity against Staphylococcus. aureus, Listeria. monocytogenes and Bacillus cereus compared to Salmonella enterica, Escherichia coli and Pseudomonas aerogenosa. The effectiveness of inhibition of the microbial biofilms formation of S.aureus, L. monocytogenes and B. cereus compared to S. enterica, E. coli and P. aerogenosa was analyzed at a concentration of 100 μg/ ml.

The present study aimed to micropropagate two date palm cultivars (Zaghlol and Barhy) using immature female inflorescence and various growth regulators combinations. This experiment was done in Biotechnology Laboratory, Department of Genetics, Faculty of Agriculture Zagazig University, during three consecutive seasons 2017, 2018, and 2019. Three types of culture media were used for initiation stage, results showed that initiation medium1 (1.0 mg /l 1-Naphthaleneacetic acid (NAA) + 0.1 mg Indole-3-acetic acid (IAA) + 1.0 mg /l 2,4-Dichlorophenoxyacetic acid (2, 4-D)) was the best medium that recorded the highest callus formation rate in both Zaghlol and Barhy cultivars. But the Barhy cultivar showed higher response for callus formation than Zaghlol cultivar, especially for number of days to initiate callus (average mean 125.58 days compare to 279 days for Barhy and Zaghlol, respectively. For plant regeneration stage, it was used three plant regeneration media. Results showed that plant regeneration medium 1 (NAA 0.5 mg/l +benzyl adenine (BA) 2.0 mg/l) showed the best value for each of number of leaves (19.35), leaf length (39.75 cm) and number of days to initiate regeneration (19). Two types of rooting media were used for root formation, it was found that rooting medium 1 (Indole-3-butyric acid (IBA) 2.0 mg/l + BA 2.0 mg/l) gave higher response than rooting medium 2 (NAA 2.0 mg/l +BA 2.0 mg/l) for almost measured criteria except root length. Also, using rooting medium 1 decreased the number of days for root formation to 40 days compared to 110.25 days obtained from rooting medium 2.

This experiment was conducted to study the effect of dietary antibiotic and essential oil supplementation on growth performance ]live body weight (LBW), daily body weight gain (LBWG), feed intake (FI) and feed conversion ratio (FCR)[ and carcass characteristics of growing Japanese quail. A total number of 360 one week old Japanese quail chicks were randomly distributed into 8 treatment groups each of 45 chicks with three replicates )15 chicks each). Chicks of all experimental groups had nearly the same average initial weight. The 1st group was fed the basal diet without supplementation as control, the 2nd was fed the basal diet supplemented with 0.50g antibiotic (colistine)/kg diet. The 3rd and 4th groups were fed the basal diet supplemented with 0.50 ml and 1.0 ml ginger oil (GO)/kg diet, respectively. The 5th and 6th groups were fed the basal diet supplemented with 0.5 ml and 1.0 ml cinnamon oil (CO) /kg diet, respectively. The 7th and 8th groups were fed the basal diet supplemented with 0.50 ml and 1.0 ml /kg mixture of GO plus CO (1:1), respectively. Results showed that chicks received 0.25 ml GO and 0.25 ml CO/kg diet had significantly (P<0.05) higher LBW compared with those received 0.5 g antibiotic /kg diet. Daily body weight gain significantly (P<0.05) increased when birds received diets containing different levels of GO or CO and 0.25 ml GO +0.25 ml CO/kg diet as compared with birds received 0.5 g antibiotic/kg diet. No significant differences in feed intake were recorded among dietary treatments during all the studied experimental period (1-3, 3-5 and 1-5 weeks of age). The better feed conversion ratio (FCR) value was recorded by chicks fed diet supplemented with 1.0 ml CO/kg diet, while the poorest FCR value was recorded by chicks fed 0.5 g antibiotic /kg. In addition, percent of carcass, dressing and gizzard were significantly (P<0.01) affected by dietary treatments. It could be concluded that GO and CO could act as a good alternative to antibiotics (colistine) in growing Japanese quail diets.

تعتبر التجارة الخارجية محورا هاما في التنمية الاقتصادية، وتلعب دوراً رئيساً في الاقتصاد العالمي، ومن أهم تداعياتها في هذا الشأن هو تنمية الصادرات وفي هذا الإطار قامت الدراسة بتقدير وتحليل بعض المؤشرات الرئيسية لتطور أداء التجارة الخارجية الزراعية العربية خلال العقدين الماضيين، واعتمدت الدراسة على البيانات المنشورة من الهيئات الإقليمية والدولية المعنية، وبلغت الصادرات الزراعية البينية العربية حوالي 106.9، 96.1 مليار دولار في عامي 2015، 2016 على الترتيب بنسبه 12.5% ،12.1% من إجمالي الصادرات العربية على التوالي، ووفقا لتقديرات الدراسة لم تغط الصادرات الزراعية العربية سوى 22.6% ،24 % من واردتها خلال عامي 2015 و2016 علي الترتيب وأتت مصر في المرتبة الأولي عند ترتيب الدول العربية تنازليا طبقا لنسبه صادراتها من إجمالي الصادرات الزراعية العربية البينية، حيث بلغت مساهمتها حوالي16%، تليها سوريا والسعودية بنسبة 13% لکل منهما، وفي شأن تطور تغطية الصادرات الزراعية البينية للواردات الزراعية البينية العربية فقد حققت جملة الصادرات الزراعية البينية زيادة کبيرة عن الواردات الزراعية في الدول العربية بنسبة بلغت حوالي 123% في عام 2011، ثم انخفضت نسبة التغطية إلى حوالي 68% في عام 2012، واستمرت في التدهور حتى عام 2016، وحافظت السودان بالکاد على تغطية صادرتها الزراعية البينية العربية لوارداتها من الدول العربية، حيث بلغت نسبة تغطية الصادرات للواردات السودانية، حوالي 102% في عام 2016.وهذا يدل على عجز الإنتاج المحلى العربي عن توفير فائض کاف للتصدير من السلع الزراعية بمواصفات قادرة على اختراق الأسواق بأسعار وجودة تنافسية، وهذا يعکس الفجوة التکنولوجية من حيث الکم والکيف بين الزراعة العربية والعالمية، تقدير "دليل هرشمان"، لأهم المجموعات السلعية الزراعية الرئيسية يبين بصفة عامة أن الصادرات العربية البينية تميل إلى التنوع وليس الترکز، حيث أن أهم مجموعة سلعية في سلة الصادرات موضوع الدراسة وهي الألبان قدّرت قيمة دليل هيرشمان لها بحوالي 0.37، تليها الخضر بقيمة 0.26، ثم الفاکهة بقيمه 0.25، ثم الحيوانات الحيه بقيمة 0.22، ثلاث من المجموعات الأربع هي سلع سريعة التلف (الألبان، الخضر، والفاکهة) يتطلب رفع کفاءتها التسويقية قيام شبکة مراحل التجهيز والتخزين والتعبئة والنقل المتقدمة بما يتوافق مع استراتيجية التنوع الکمي والکيفي للصادرات، ويمکن رفع القيمة المضافة لتجارة الحيوانات الحية بقيام صناعة حديثة لتجهيز اللحوم وتجهيز المنتجات الثانوية خاصة الجلود والأسقاط القابلة للأکل
ولإبراز أهم الأسواق العربية المصدرة لهذه المجموعات السلعية الأربع الأولى للأقطار العربية، أوضح تقدير الترکز الجغرافي للفترة (2012-2016) أن أهم الدول المصدرة لمجموعه الألبان هي السعودية بنسبة 33%، تليها مصر بنسبه 13%، ولکن ارتفاع مساهمة السعودية في صادرات الألبان راجع لتکثيف الاستثمار قي نشاط أهدر الموارد المائية المحدودة وأدى لنمو إنتاج اللبن ومنتجاته بحوالي 7.7% سنويا، مقابل نمو الطلب الفعال بحوال 5% سنويا، مع ارتفاع تکاليف الإنتاج واستنزاف 500 طن مياه عذبة لإنتاج وتجهيز 1طن لبن رغم ندرة المياه العذبة وارتفاع تکاليفها الاجتماعية، وبلغت أسعار منتجات الألبان المستوردة 50% من نظيرتها المنتجة محليا، مع غياب الميزة النسبية للسعودية في القطاع الزراعي، وتمثل السودان أهم الدول العربية المصدّرة للحيوانات الحية بنسبه 21% من جملة الصادرات العربية البينية لهذه المجموعة السلعية، وتترکز صادراتها إلى السعودية کأضاحي في موسم الحج، وأهم الدول المصدرة لمجموعه الفاکهة هي مصر بنسبه 26%، تليها سوريا بنسبه 15%، فالأردن بنسبه 12%، وتبرز الأردن کأهم الأسواق العربية المصدرة لحاصلات الخضر للدول العربية، رغم ضعف حجم مواردها الزراعية الطبيعية من أراضي ومياه، لتمتعها بميزة مکانية للتصدير البري ولاستخدامها لتقنيات فيزيقية متقدمة (زراعة محمية) ونظم ري موفرة للمياه، وتقنيات بيولوجية متقدمة (أصناف عالية الإنتاجية)، وتمتعها بتفضيلات إقليمية في تلقي مساعدات اقتصاديه من الدول الکبرى والتکتلات الاقتصادية العالمية والمنظمات المالية الدولية، وتترکز صادراتها في أسواق دول الخليج العربي والعراق.

Two field experiments were carried out at the experimental farm (Ghazala Village), Faculty of Agriculture, Zagazig University, Sharkia Governorate, during 2016/2017 and 2017/2018 seasons to study the influence of three planting densities, (28000, 35000 and 46666 plants/fad.) three levels of N fertilizer (80,100 and 120 kg/fad.) and two levels of potassium fertilizer (24 and 48 kg k2O/fad.) on yield and its attributes as well as quality of sugar beet grown in clay soil. Results of combined analysis illustrated that, decreasing planting density from 46666 to 35000 or 28000 plants/ fad., significantly increased root length, root diameter and fresh root weight g/plant; on the other hand the highest planting density (46666 plants/fad.) produced higher sucrose, extractable sugar percentages, sugar and recoverable sugar yields/fad., than low or medium densities. Raising N fertilizer levels significantly affected yield and its attributes as well as quality of sugar beet. Where, the results of the combined analysis indicated that, each increment of nitrogen fertilizer level from 80 up to 120 kg N/fad., cm was accompanied with a significant increase in root length, root diameter, fresh root weight/plant, root and recoverable sugar yields/fad., but significantly decreased sucrose (%). Data of combined analysis also revealed that application of 48 kg K2O/fad., significantly increased root yield attributes i.e., root length root diameter (cm), fresh root weight g/plant, sucrose, extractable sugar percentages, as well as, root and recoverable sugar yields ton/fad., compared with supply of 24 kg K2O/fad. Interactions between the studied factors (according to the combined analysis) indicated that the highest root yield (ton/fad.) was achieved when sugar beet was sown with the highest plant density of 46666 plants/fad., and fertilized with 120 kg N/fad. As well as, the highest value of root diameter (cm) was achieved under the application of 120 kg N/fad., and addition of 48 kg K2O/fad., while, the interaction between planting densities and potassium fertilizer levels had no significant effects on all studied traits.

In 2016 five maize inbred lines were crossed in all possible combinations without reciprocals by using a half diallel crosses mating design to obtain 10 single crosses. Parental inbred lines and their F1 single crosses were evaluated through 2017 season to evaluate the role of general and specific combining ability, heterosis and the morphological characteristics. A randomized complete block design with three replicates was used. Results showed that mean squares of genotypes, general combining ability (GCA) and specific combining ability (SCA) were highly significant for all studied yield traits. The GCA/SCA ratio was less than unity for all studied traits, this means that these traits are predominantly controlled by non-additive gene action. Positive significant GCA effects were found for all studied traits. Based on GCA estimates, it could be concluded that the best combiners were Inb 209 and Inb 239 for most of studied traits. This result indicated that these inbred lines could be considered as good combiners for improving yield and its attributes. Positive significant SCA effects were found for all studied traits. Based on SCA effects, the best crosses for ear diameter, 100-kernel weigh and kernel number/row was C1; for ear length was C10 and for ear weight/plant, grain weight/plant and shelling percentage was C8. Results showed positive significant heterosis values for all studied yield traits. The best crosses over both their mid-parents and better-parents for ear diameter and 100-kernel weigh was C2; for ear length and kernel number/row was C5; for ear weight/plant and grain weight/plant was C9 and for shelling percentage was C8.

Two field experiments were carried out at a Private Farm named Royale herbs in El-bawiti Village, El Wahat El-Bharia District, Giza Governorate, Egypt during the two consecutive seasons of 2016/2017 and 2017/2018 to study the effect of different fertilizer types (mineral, organic and bio fertilizers) treatments on vegetative growth, yield components and volatile oil as well as total carbohydrates percentage of chamomile plant. The performance of organic fertilization (compost and humic acid) and biofertilization (nitobein or/and phosphorein) were compared with standard, commercial rates of N, P, K and Mg fertilizers with respect to the growth, yield and essential oil of Matricaria chamomilla. In the two successive seasons, plants treated with chemical fertilization showed a significant increase in vegetative growth (plant height, number of branches per plant, fresh and dry weights per plant) compared to the other types of fertilizers under study. The highest rate of chemical fertilizers (N, P2O5, K2O and MgO at 125, 100, 62.5 and 30 kg/faddan, respectively) recorded the highest value in each yield component (flower heads number per plant as well as flower heads air-dry weight per plant and per faddan) compared to the other ones under study, in most cases. In the same time, organic fertilization (30 m3 compost + 1 kg humic acid/ faddan) recorded an increase in these yield components compared to the other organic fertilizer rates in both seasons. Also, fertilization at (1 kg of nitrobein + 30 m3 compost/faddan) recorded a significant increase in volatile oil percentage of chamomile plant compared to either of sole chemical or biological fertilizer rates under study.

Two field experiments were carried out at a Private Farm in Qeft District, Qena Governorate, Egypt, during the two consecutive seasons of 2016/2017 and 2017/2018. To study the effect of humic acid rates (0.0, 1.0, 2.0 and 3.0 l/fad.), sprays number (one, two, three and four times at 25, 25 and 40 , 25, 40 and 55 as well as 25, 40, 55 and 70 days after planting, respectively and their combinations on vegetative growth, flower yield components and volatile oil production of chamomile plant.The obtained results referred to that the maximum values of plant height, branch number/plant, herb dry weight/plant as well as air-dry weight of flower heads/ plant and/fad., were detected when chamomile plants were applied with the highest rate of humic acid and sprayed three times during the season, in most cases. In the same time, the treatment of humic acid rate at 3 l/faddan combined with three application times was superior treatment in volatile oil percentage in flower heads and volatile oil yield (ml/ plant and l/faddan) of chamomile compared to the other ones under study during both seasons. Generally, this combination treatment seems promising in the development of sustainable crop growth and yield advantages under Qena Governorate conditions.

Two Field trials were carried out at Abo-Gensho village, Abshway District, Fayoum Governorate, Egypt, during two successive summer seasons of the 2017 and 2018 to study the effect of irrigation scheduling treatments andfoliar spray with chitosan concentrates on growth parameters, yield and its components and some water relations of eggplants cv. black beauty. Three irrigation scheduling treatments based on coefficients of cumulative pan evaporation (CPE), i.e. I1: 1.1, I2:0.9 and I3: 0.7 CPE with three chitosan concentrates, i.e. C1: 0 (without addition, control), C2:40 and C3:80 mg l-1 with three replications in a strip plot design. Results indicated that the highest plant growth and eggplant fruits yield in both seasons were detected from a combination of irrigation at 1.1 CPE and spraying by 80 mg l-1 as chitosan concentrate. Further, it resulted in highest values for seasonal consumptive use (ETC) as well as water use efficiency (WUE). On other hand, it could be recommended the combination of irrigation at 0.9 CPE and applying 80 mg l-1 as chitosan concentrate in Egypt for enhanced eggplant fruits yield especially under deficit irrigation water conditions.

Tow field experiments were conducted during the two successive winter seasonsof 2016/ 2017 and 2017/2018 in the Experimental Farm of Kaha Station, Qalubia Governorate on broad bean cv. luz de tout and during summer season of 2017- 2018 in the location of Vegetable Research Departments, Horticulture Research Institute, Agriculture Research Center, Dokki on tomato Alissa hybrid. The aiming of the experiments were to examine the effect of three rates of mineral fertilizers NPK, i.e.100% (as control), 75% and 50% either for broad bean or tomato and four safety materials, i.e. water (as control),seaweed extract (Tohlob gel) at 0.5 g/l,goosefoot extract andstingingnettle extract at two concentrations (10 and 20% of each) as foliar spray and their interactions on the vegetative growth, yield and its components of tomato and broad bean plants. Tomato fertilized with 75% of the recommended rate of NPK and sprayed with stinging nettle extract at 20% gave the highest value for each of vegetative growth parameters in both growing season. Moreover, as general the results showed that all treatments used, especially plants fertilized with 50% or 75% of the recommended rate of NPK and sprayed with goosefoot extract or stinging nettle extract at 20% of each, increased thetotal yield and its components, whereas decreased the percentage of infested fruits by blossom end rot disease compared with the control. The highest value of VC was obtained from using seaweed extract and fertilization by 50% of recommended NPK rate. On the contrary, the highest value of Juice acidity was recorded by the control treatment. Fertilizing with 100% of the recommended fertilization and foliar spray with goosefoot extract at 20% gave the highest value for each of total sugar (%) and K (%). All treatments had no significant impact on fruit length, fruit diameter, fruit shape, fruit firmness, flesh thickness and number of loculi. From forgoing results it could be concluded that, spraying tomato plants with goosefoot extract or stinging nettle extract at 20% of each gave the highest value for each of vegetative growth and total yield under fertilizing with 50% or 75% of the recommended fertilization. Regarding to broad bean, results indicated that, adding 75% followed by 50% of the recommended mineral fertilization and spraying by goosefoot extract at 20% concentration gave the highest values of all vegetative growth parameters, except plant length which showed favorable result under 100% from fertilization and spraying the plants with nettle extract at 20% concentration and leaf area which increased by adding 100% of recommended fertilizer level and spraying plants with goosefoot extract at 20% concentration. Spraying broad bean plants with stinging nettle extract at 20% concentration under 50% of the recommended fertilization gave the highest value for each of pod diameter and weight of 100 fresh seeds. Total pod yield/fed significantly increased by adding 100% then 75% of the recommended fertilization and spraying the plants by goosefoot extract at 20% then 10%, respectively while spraying broad bean plants with goosefoot extract at 20% concentration under 50% fertilization significantly increased P and K(%) but spraying broad bean plants with 20% concentration under 75% of the recommended fertilization gave the highest value for each of N and protein (%)in both seasons. Generally spraying broad bean plants with goosefoot or stinging nettle extract at 10% concentration under 75% or 50% of the recommended fertilization led to increase total green pod yield and its components, in addition saving 25% to 50% of the recommended fertilization.

This work was carried out during 2016 and 2017 seasons in post-harvest Lab. Pomology Dept. Cairo University, Egypt. The quality and internal (physical and chemical) changes in apricot fruits (Prunus armeniaca L.) coated with different treatments of Nano chitosan and Nano silicon were studied after different storage periods of cold storage at 1°C and 90-95% (RH). Nano chitosan was prepared with 0.5% concentration and Nano silicon was prepared with 2% concentration, each of them was tested individuallyor in combination with Thiabendazole (TBZ). The changes in fruit firmness, weight loss, discarded fruit percentage, fruit panel, total acidity (TA), total soluble solids (TSS), and ascorbic content (Vitamin C) at intervals were estimated during 7 weeks. The results of the two successive seasons indicated that the application of Nano chitosan and silicon coatings maintained fruit firmness compared with the control (dipped in TBZ) without significant differences. The application with 0.5% Nano chitosan + TBZ treatment maintained higher firmness values. On the other hand, Nano-chitosan coating + TBZ treatment maintained fruit acidity, fruit panel test and Vitamin C content more than the uncoated control and other treatments without significant differences. While, all coating treatments increased TSS values and discarded fruit percentage compared with the control without significant differences. The lowest value for each of TSS and fresh weight loss percentage was achieved by Nano chitosan 0.5% + TBZ treatment. Similarly, that treatment significantly decreased fresh weight loss percentage compared with the other treatments.

The current study was done at Shenno village, Kafr El-Sheikh Governorate, Egypt during 2017/2018 and 2018/2019 seasons. The results showed that the mean numbers of cotton leafworms larvae throughout the growing season 2017/2018 were 22.10, 16.57 and 12.25 larvae/ sample (30 plants) to the three plantations, respectively. In 2018/2019 season, the mean numbers of larvae/sample were 22.45, 16.14 and 11.25 larvae to the three plantations, respectively. Statistical analysis proved significant differences among three plantations in the two seasons In 2017/2018 season, the overall mean of reduction values in the larva numbers were 82.76,82.33,81.50,81.79 and 81.66% for Tac 48% EC, Diracomel 90% SP, Billy 25% WG, Kenzaban 50% EC and Marshal 20% EC, respectively. Also,the root yield of sugar beet were 21.666, 21.690, 21.642, 21.714 and 21.690 ton/faddan for the previous insecticides, respectively, as compared with 11.928 ton/fad., in the untreated plots. Whereas, the sugar yield were 4.008, 3.904, 3.919, 3.936 and 3.997 ton sugar/ faddan to the plots treated with above mentioned insecticides, respectively, as compared with 1.312 tons sugar/faddan in the untreated plots. In 2018/2019 season, the overall mean of reduction values were 87.00, 87.00, 88.00, 88.03 and 87.33% for Tac 48% EC, Diracomel 90% SP, Billy 25% WG, Kenzaban 50% EC and Marshal 20% EC, respectively. Also, the root yield of sugar beet were 21.547, 21.452, 21.500, 21.404 and 21.428 ton/faddan for the treated plots with the previous insecticides, respectively, as compared with 5.976 ton/faddan on the untreated plots. Whereas, the sugar yields were 3.878, 3.818, 3.913, 3.833 and 3.878 ton sugar/faddan to the treated plots with the above mentioned insecticides, respectively, as compared with 0.604 tons sugar/faddan in the untreated plots. Statistical analysis indicated significant differences among treated plots with all insecticides and untreated ones in reducing larva numbers, increasing root and sugar yields in the two seasons. Finally, these results indicated that the importance of insecticides in reducing cotton leaf worms larvae, consequently enhancing root and sugar yield of sugar beet crop.

Cassida vittata Vill.(Coleoptera :Chrysomelidae) is avery important insect pest to sugar beet crop. Its larvae and adults feed upon sugar beet leaves causing significant defoliation, consequently reduce root weight and sugar percent (%) to this crop. Entomopathogenic microorganisms, mainly entomopathogenic bacteria, is a vital factor of the natural mortality against insects. Research on microbial pathogens of insects is increasing to find out environmental friendly alternatives to hazardous chemicalinsecticides. This investigation was done at the Experimental Farm of Sakha, Agricultural Research Station, Kafr Elsheikh Governorate, Egypt during 2018 and 2019 seasons. Obtained results showed that 11(29.72%) C. vittata larvaeout of 37 individuals died naturally with Bacillus aryabhattai. Six(29.72%) C. vittata adults out of 25 individuals died naturally due to exposure to 108 cfu/ml suspension, which used for laboratory and field tests. In a laboratory test, the mortalities of larvae were 20.00, 30.00 and 45.00% after 3, 7 and 10 days post-treatment, respectively. Whereas, the mortalities of adults were 10.00, 25.00 and 40.00% after 3, 7 and 10 days post-treatment, respectively. Also, in a field test, the reduction of larvae were 12.86, 29.79 and 43.99% for 3, 7 and 10 days after treatment, respectively. Reduction of adults were 14.06, 27.05 and 39.84% for 3, 7 and 10 days after treatment, respectively. This strain was identified by GATC (biotech sequence company, Germany), for the first time in Egypt. These results conclude that this strain is an effective biocontrol agent against C. vittata larvae and adults in sugar beet fields.

Powdery mildew, caused by Blumeria graminis f. sp. tritici, is an important disease of bread wheat (Triticum aestivum L.) in many countries worldwide, including Egypt. Powdery mildew infects all parts of wheat plants that negatively affect grain yield and therefore caused economic loss. Some microorganisms i.e. Bacillus subtilis, B. chitinospora, B. pumilus and yeast (Rhodotarula sp.) were used in the current study as biocontrol agents (BCAs) for controlling powdery mildew in wheat variety (Sakha93), under field conditions, compared to the recommended synthetic fungicide; Tilt. The superior and best treatments decreasing infection type (IT), disease severity (%), and increasing 1000 kernel weight and grain yield per plot. Application of B. subtilis and B. chitinospora, were compared to the other treatments and the tested fungicide. Scanning electron microscopy studies confirmed the superiority of the aforementioned two biocontrol agents (BCAs), as application of each, minimized suppressed mycelial growth and collapsed the spores of the causal pathogen. Application of B. chitinosporain, particular, suppressed the conidial germination, caused a rupture, and deformation of germ tube. Also, both mycelia and conidiospores became shrinking on the surface of the treated wheat leaves. Extracts of the four microorganisms used in this study interacted directly with Blumeria graminis, and this antifungal effect was responsible for the observed disease protection. The obtained results in this investigation gave an evidence to the possible use of such microorganisms as safe and effective alternatives for controlling powdery mildew disease of wheat under field conditions.

A Total of 36 water samples were collected from 3 irrigation and drainage canals in Fayoum Governorate, Egypt, to identify the quality for irrigation. Site 1; Bahr Wahby Canal, Site 2; Batss drain and Site 3; El Gharaq drain. Measurements included pH, EC soluble ions, and heavy metals during 12 months (one sample each month for each site) from April 2016 to March 2017. The pH varied from 7.00 to 9.32, while EC average for sites 1, 2, and 3 were 2.13, 2.20, and 3.85 dSm-1, respectively. Sodium adsorption ratio (SAR) values were 4.88, 4.98 and 7.53 for sites 1, 2, and 3, respectively. Water quality for site 1and 2 was C3S2 (high salinity and medium sodicity hazards), while for site 3 they were C4S2 (very high salinity and medium sodicity hazards) and could be used for crops which are tolerant to salinity. All heavy elements at the three sites were below the permissible limits. Water measurements and assessment are important in determining their quality.

The effect of addition moringa leaves extract (MLE) on physical, chemical and sensory properties of luncheon was investigated. Luncheon samples were supplemented with 0.5, 1.0 and 1.5% of MLE. Results showed that supplementation of luncheon with MLE increased its content of protein, fiber and antioxidants. Protein content ranged from 8.49% in control to 10.90% in luncheon sample with 1.5% MLE. Total phenolic content of MLE was ranged from 65 to 67 mg/100g (as Gallic acid equivalent) while, the scavenging effects of 100 µl of MLE were ranged from 79.51 to 88.57%. The thiobarbituric acid number (TBA) values increased for all the investigated luncheon samples gradually during storage period. The highest value for TBA was noticed in L1 (control sample 1) (0.5239) after four weeks of cold storage while, the lowest value was observed with luncheon meat containing 0.01% butylated hydroxytoluene (BHT) (L2) (0.1251) at zero storage. The total polyphenol contents and antioxidants activity increased in luncheon meat after the addition of moringa leaves extract. All the luncheon meat samples containing moringa leaves extract were generally acceptable.

The aim of this work was to study the level of nutritional knowledge of mothers about breast and artificial feeding, sources of nutritional knowledge of mothers was also studied. This cross-sectional study was conducted on 200 mothers, selected randomly from urban and rural areas in Sharkia Governorate, Egypt during the period from March to May, 2019. All mothers filled a questionnaire to evaluate their knowledge about breast and artificial feeding. The results showed that the highest percentage of working and housewives mothers (50.0 and 53.1%) were aged 25-32 years old, respectively. About 65.8 and 46.3% of the working mother and housewives mothers were from urban area, respectively. The majority of working mothers were educated. The results revealed that the majority of working and housewives mothers (97.5 and 92.1%) were married. The results indicated that the children sex was 63.2% male and 36.8% female for working mothers. Whereas, they were 46.9% male and 53.1% female for housewives. It is obvious that the 57.9% of working mothers had children their age were (576-850) days. Whereas, the highest proportion of housewives (37.7%) had children their age was 25-300 days. The results indicated that the percentage of good nutrition children was 97.5 and 89.5% of housewives and working mothers, respectively. The results declared that the working and housewives mothers get nutritional knowledge by percent 63.2 and 46.3% from visiting doctor, respectively. The results illustrated that the highest percentage of working and housewives mothers (84.2 and 60.5%) had low level of general knowledge about breast feeding. Also, most of working and housewives mothers (76.3 and 62.3%) had low level of general knowledge about artificial feeding. It can be concluded that the most of subjects had low level of knowledge about breast and artificial feeding. Therefore, the recommendions are the use of programs to raise awareness for mothers about breast and artificial feeding.

This work was carried out to study the effect of three mixture immersion solutions on the quality of osmotic dehydration of tomato (Solanum lycopersicum) slices. The first mixture was sugar syrup 30°Brix, 50° Brix and 60° Brix. The second mixture was sugar and calcium chloride (CaCl2) (500ppm) in sugar syrup 30° Brix, 50° Brix and 60° Brix. The third blending 10% salt (NaCl) in sugar syrup 50° Brix as osmotic agents on osmotic dehydration of tomato slices with immersion duration (6 and 8 hours) at constant tomato ratio of (1:4). After this step the tomato slices in three mixtures were laid on the drying cabin for sun drying of tomato at 30 - 45°C. The moisture content and some chemical properties such as (total soluble solids TSSo Brix, total titratable acidity TA (%) and pH-value) of tomato slices were determined. The results obtained showed that the lowest pH value was obtained from the treatment with 50° Brix sucrose with NaCl 10% (3.18), the highest content of total soluble solids was obtained from the treatment with 50° Brix sucrose with NaCl 10% and the highest total titratable acidity treatment was due to reatment with 50° Brix sucrose with NaCl 10% (0.720) consequently, the best treatment was that of 50° Brix sucrose with NaCl 10%. There were high significant differences between it and other treatments. From the obtained results, it could be concluded that the osmotic dehydration have highly impact on the quality control of tomato slices.

This investigation was carried out at experimental and research Farm, Faculty of Agriculture, Zagazig University, Egypt during six winter seasons 2012/2013, 2013/2014, 2014/2015, 2015/2016, 2016/2017 and 2017/2018. The aim of this study is to evaluate earliness and spineless mutant lines of safflower. The morphological traits (earliness, number of days to maturity) were recorded for two lines of safflower, line III and line VI and their promising mutant lines. The results confirmed the stability of 8 promising mutant lines for line III, (4, 7, 9, 10, 12, 14, 17, 18) and 6 promising mutant lines for line VI, (1, 2, 5, 6, 9, 7). In the M10 generation, 9 criteria were recorded, 1-plant height (cm), 2-number of branches per plant, 3-number of capitula per plant, 4-number of seeds per capitulam,5-number of seeds per plant, 6-100 seed weight (g), 7-seed weight/plant (g), 8-days to maturity, 9- oil (%). High broad sense heritability (h²) of No. of capitula per plant, 100-seed weight, seed weight per plant, days to maturity and oil content were 79.16%, 77.95%, 94.91%, 79.23% and 69.41%, respectively among line III and their mutant lines. The present study confirmed that the relationship between characters under study varied between genotypes for example, oil content slightly negative correlated with seed weight per plant and was different among genotypes (-0.2495, - 0.0678 and - 0.2358) for line III and line VI and for over all genotypes, respectively. These results confirmed that selection of oil content and seed weight per plant could be achieved in line VI and their mutants (- 0.0678). In addition, highly positive correlation between seed weight per plant and each of No. of capitula per plant and No. of seeds per plant at line VI, was observed. These results showed the simple heritable system of days to maturity, than the spineless criteria. These promising mutant lines had 168 and 170 days to maturity of line 4 and 7 from line III and 177 and 182 days of line 2 and 5 from line VI by comparison to 180 and 188 days for control of line III and line VI, respectively. These results suggest the improvement possibility of new Egyptian varieties for cultivation of harsh and poor land desert.

Sixty- four male dromedary camel testes from different breeds (Fellahi, Maghrebi and Sudani) during the breeding and non –breeding seasons were used. The experimental work aimed to define the effect of breed and seasons on testicular measurements and sperm characteristics. The penetrating ability of spermatozoa into she-camel cervical mucus was also assessed. The obtained results revealed that, testes weight (g), testicular volume (cm3), scrotal circumference (cm) and testes tone firmer score were significantly (P<0.05) higher during the breeding than during the non- breeding season, while insignificant differences between Fellahi and Maghrebi than Sudani camels were detected. Percentage of sperm motility and sperm-cell concentration (x106/ml) were significantly (P<0.05) higher, while the percentages of dead spermatozoa, abnormal spermatozoa, acrosomal damage and chromatin damage of spermatozoa were significantly (P<0.05) lower in the breeding than in the non-breeding season in Fellahi and Maghrebi camels as compared with Sudani ones. Penetrating ability of spermatozoa into she-camel cervical mucus was significantly (P<0.05) better during the breeding than non- breeding season in the different breeds (Fellahi, Maghrebi and Sudanese camels). The penetrating ability of spermatozoa into she-camel cervical mucus was not significant in the various breeds (Fellahi, Maghrebi and Sudanese camels). Moreover, the prolongation of incubation time at 37ºC for 4 hours significantly (P<0.05) decreased the penetrating ability of spermatozoa into she-camel cervical mucus either in the breeding or the non-breeding season with the different dromedary camel breeds. In conclusion, sperm characteristics and ability of Fellahi and Maghrebi camel spermatozoa to penetrate cervical mucus during the breeding season showed better performance than Sudani camel spermatozoa.

The objectives of this study were to identify the allelic and genotypic polymorphisms of fatty acid binding protein 4 (FABP4) gene and its association with growth traits (weaning weight, post-weaning daily gain and marketing weight), feed efficiency traits (feed intake and feed efficiency), body indices (body mass index, skeletal muscle index, body index and relative body index) and carcass traits [hot carcass weight, dressing (%), neck (%), for-legs (%), ribs (%), loin (%), hind-legs (%), abdominal fat (%) and tail (%)] in thirty males of the Egyptian Ossimi lambs. The polymerase chain reaction-single strand conformational polymorphism (PCRSSCP) tool was used to identify the allelic and genotypic polymorphisms in FABP4 gene. The SSCP analysis detected two alleles (A and B with frequency of 0.73 and 0.27, respectively), and three genotypes (AA, AB andBB with frequency of 0.67, 0.13 and 0.20, respectively). The FABP4 genotype showed significant effect (P ˂ 0.05) on feed efficiency and body mass index; and high significant effect (P ˂ 0.01) on post-weaning daily gain, marketing weight, feed intake, skeletal muscle index, hot carcass weight and tail (%). However, the FABP4 genotype did not show significant effect (P > 0.05) on the values of the other studied traits [weaning weight, body index, relative body index, dressing (%), neck (%), for-legs (%), ribs (%), loin (%), hind-legs (%) and abdominal fat (%)]. The presence of A allele was significantly associated (P ˂ 0.05) with body mass index and hot carcass weight; and high significantly associated (P ˂ 0.01) with post-weaning daily gain, marketing weight, feed intake, feed efficiency, skeletal muscle index and neck (%), however, the presence of B allele in the genotype high significantly (P ˂ 0.01) affected post-weaning daily gain, marketing weight, feed intake, feed efficiency, body mass index and hot carcass weight. Obtained results showed an association between the FABP4 gene (B allele) and post-weaning daily gain, marketing weight, feed intake, feed efficiency, body mass index and hot carcass weight of the Egyptian Ossimi lambs. Consequently, applying the marker assisted selection using the FABP4 gene is warranted to increase these traits and will be of considerable economic value in sheep production.
