EFFECT OF FOLIAR SPRAYING TIMES AND LEVELS OF YEAST EXTRACT AND BORON ON PRODUCTIVITY AND QUALITY OF SUGAR BEET UNDER SANDY SOIL CONDITIONS
In order to study the effect of foliar spraying times and levels of yeast extract and boron on productivity and quality of sugar beet cv. Hossam, a field experiment was carried out at Kalabsho Experimental Farm (sandy soil), Dakahlia Governorate, Sugar Crops Research Institute, Agricultural Research Center, Egypt, in two successive seasons of 2014/2015 and 2015/2016. Two experiment trails were laid-out in strip-split plot design with four replications. The vertical-plots were assigned with times of foliar application with yeast extract and boron (after 75 and 90 days from sowing). The horizontal-plots were occupied with foliar spraying with yeast extract levels i.e. without spraying (control treatment), spraying with 2, 4 and 6 g yeast/liter. The sub-plots were allocated to foliar spraying with boron levels (control, 100 and 200 mg boron/liter). The results showed that delaying spraying sugar beet plants with yeast extract and boron from 75 up to 90 days from sowing resulted in gradual and significant increases and recorded the highest value for each of root and top fresh and dry weights/plant, root dimensions, purity and sucrose percentages, root and sugar yields/fad., as well as the decrease in the values of sodium, potassium and α-amino nitrogen percentages of sugar beet juice. The best results of yield components, root juice quality parameters and yields were resulted from foliar spraying sugar beet plants with yeast extract at the rate of 6 g/liter in both seasons. The highest values of all aforementioned yield components, root juice quality parameters and yields were obtained as a result of spraying sugar beet plants with 200 mg boron/liter in both seasons. It can be recommended that spraying sugar beet plants after 90 days from sowing with 6 g yeast extract and 200 mg boron/liter to maximize sugar beet productivity and quality under the environmental conditions of sandy soils.

IMPACT OF SOWING MODELS, NITROGEN LEVELS AND BIOFERTILIZATION ON YIELDS AND QUALITY OF SUGAR BEET UNDER SANDY SOIL CONDITIONS
The aim of this research is to study the influence of sowing models (one side of ridges, 60 cm apart, 15 cm between hills and both sides of terraces, 90 cm apart, 20 cm between hills), nitrogen fertilizer levels (70, 90 and 110 kg N/fad.) and biofertilization treatments (treate soil with Cerialin, Rhizobacterin and the mixture of Cerialin and Rhizobacterin) on yield and quality of sugar beet, Karam cultivar under sandy soil conditions. Two field experiment were carried out at Kalabsho Experimental Farm, Dakahlia Governorate, Sugar Crops Research Institute, Agricultural Research Center, Egypt, during 2014/2015 and 2015/2016 seasons. The experiments were carried out in split-split plot design with four replications. The main plots were assigned to sowing models. The sub-plots were occupied with nitrogen fertilizer levels. While, the sub-sub plots were allocated with biofertilization treatments. The obtained results showed that sowing sugar beet in both sides of terraces, 90 cm apart, at 20 cm between hills attained the highest values of yield components, most of root juice quality parameters and yields, followed by sowing in one side of ridges, 60 cm apart, at 15 cm between hills in both seasons. The highest value for each of yield components, most of root juice quality parameters and yields were produced from fertilizing beet plants with 110 kg N/fad in both seasons. However, application of 90 kg N/fad., induced the highest value of sugar yield and the second best value for each of yield components, root juice quality parameters, top and root yields without significant differences between them in most cases in both growing seasons. Application the mixture of Cerialin and Rhizobacterin produced the highest value for each of yield components, most of root juice quality parameters and yields in the two seasons. It can be concluded that sowing sugar beet in both sides of terraces, 90 cm apart, at 20 cm between hills and treat soil with the mixture of Cerialin + Rhizobacterin (225 g/fad., of each) biofertilizers in addition of mineral fertilizing with 90 kg N/fad., to improve productivity and quality of sugar beet under sandy soil conditions.

EFFECT OF PRECEDING CROPS AND FOLIAR MICRONUTRIENTS APPLICATIONS ON YIELD AND YIELD COMPONENTS OF BREAD WHEAT UNDER SANDY SOIL CONDITIONS
Two field experiments were conducted during 2016/2017 and 2017/2018 seasons at the experimental farm of the Agricultural Research Station, Agric. Res. Center, Ismailia Governorate, Egypt (Lat. 30° 35' 30" N, Long. 32° 14' 50" E, 10 m ASL), to evaluate the effect of fallow (control(, clover and fodder maize as a preceding crops and foliar application of some micronutrients on yield and yield components of wheat cv. Gemmiza 11. The experimental design was split plot with three replications. Main plots were allocated by preceding crops and sub plots were occupied by three micronutrients salts FeSO4, ZnSO4 and MnSO4, in seven combinations of micronutrients foliar application T1: (Fe +Zn + Mn), T2: (Fe +Zn), T3: (Fe + Mn), T4: Fe, T5: (Zn + Mn), T6: Zn and T7: Mn. Micronutrients were sprayed three times at 30, 60 and 90 days after sowing. Results showed that wheat significantly affected by the preceding summer crops. Clover as a preceding crop left good residual effect on wheat plant which gave the highest values for all studied characters e.g. plant height, number of spikes/m2, No. of spikelets/spike, No. of grains/spike, 1000 grain weight and grain yield as well as straw and grain contents from Fe, Mn and Zn in the two seasons. With respect to micronutrients, the results showed that the differences between these treatments had significant effect on each of plant height, number of spikes/m2, No. of spikelets/spike, No. of grains/spike, 1000 grain weight and grain yield. The foliar application of mixture nutrients (Fe + Mn + Zn) produced the highest values of yield and its components during both seasons. Moreover, the foliar spray of Fe, Mn and Zn (alone or together and all three nutrients) has significant effect on wheat straw and grain-Fe, Mn and Zn concentrationduring the two seasons. Also, the results indicated that the interaction between preceding crops and micronutrients treatments had insignificant effect on all studied characters, except 1000 grain weight in the first season and number of spikelets/spike in the second one. In conclusion growing wheat following to clover and foliar application by mixture of Fe+Mn+Zn produced the maximum net income valued 2186 and 2098 LE.fad-1 during two seasons, respectively, compared to the other treatments.

COMPARISON BETWEEN EFFECT OF COMMERCIAL AND NANO NPK IN PRESENCE OF NANO ZEOLITE ON SAGE PLANT YIELD AND COMPONENTS UNDER DROUGHT STRESS
Lucrative approaching of nanotechnology and its application on plant is gradually growing recently. Based on this fact an investigation was done during two successive seasons 2018 and 2019 to scrutinize the consequence of nano macro elements application represented in NPK individually or in combination and nano zeolite with and without loaded nitrogen on a sage plant grown under drought stress in comparison with commercial NPK fertilizers at a newly reclaimed area of the desert. The outcome results revealed that nano-zeolite loaded nitrogen, as well as nano-NPK mixture, donated outstanding results with reference to vegetative growth (plant height, number of branches, herb fresh and dry weights, leaf area, yield fresh weight, health index, and oil yield) beside photosynthetic rate, stomatal conductance, intercellular CO2 concentration, water use efficiency, relative water content, and chemical composition symbolized in (plant pigments, total carbohydrates, total phenols, tannins, total flavonoids, oil constituents, macro, and micro-elements) alongside indigenous hormones characterized in (gibberellic acid GA3 and abscisic acid ABA), antioxidant enzymes (peroxidase and superoxide dismutase) in contrast to the commercial dose of chemical fertilizers NPK (as control) under the same conditions. Moreover, leaf anatomical structure supported the acquired vegetative growth parameters and chemical analyses results. The outcomes of the current study gave emphasis to global warning about pollution resulted from chemical fertilizers particularly in newly reclaimed areas and safety production of medicinal and aromatic plants.

REDUCE THE HURTFUL EFFECTS OF SEA WATER SALINITY ON GROWTH, SOME PHYSIOLOGICAL AND ANATOMICAL CHARACTERS AS WELL AS YIELD OF Phaseolus vulgaris L. BY USING HUMIC ACID, PROLINE AND NAPHTHALENE ACETIC ACID
Pots experiment was designed in two summer successive seasons of 2017 and 2018 at the wire house of the Agric. Bot. Dept., Fac. Agric. Zagazig Univ., Sharkia Governorate, Egypt. Common bean plants cv. Giza 3 were foliar sprayed with different concentrations of humic acid, proline, naphthalene acetic acid and distilled water (as a control) under sea water salinity levels, i.e. 1000, 2000 and 3000 ppm and tap water (500 ppm) as a control, to examine its effects on growth, photosynthetic pigments, proline content, yield and leaf anatomy of common bean plants. Results revealed that most studied traits, i.e., plant height, number of leaves/plant, leaf area, fresh weight of roots, stems and leaves, photosynthetic pigments (chlorophyll a, chlorophyll b, chlorophyll a+b and carotenoids) and yield expressed as number of pods/plant, number of seeds/pod, number of seeds/ plant, 100-seed weight and length of pod as well as leaf anatomical parameters. Most aforementioned features were significantly decreased with increasing sea water levels up to the highest level (3000 ppm) comparison with control (tap water). On the contrary, proline content in leaves was increased with increasing salinity levels up to 3000 ppm. On the other hand, spraying common bean plants with humic acid at 2 and 4g/L, proline at 50 and 100 ppm and naphthalene acetic acid at 25 and 50 ppm had a positive significant effect in most studied traits compared to control (distilled water). In general, the most favorable treatments were foliar spray common bean plants with humic acid at 2g/L followed by proline at 100 ppm then naphthalene acetic acid at 25 ppm, respectively compared to control (distilled water). It could be concluded that spraying of humic acid, proline and naphthalene acetic acid mitigate the harmful effect of sea water salinity on common bean plants and the best treatment was interaction between irrigation with tap water or sea water at 1000 ppm and spraying by humic acid at 2 g/L.

NEMATICIDAL PROPRIETIES OF COMMERCIAL SEED OILS OF CERTAIN MEDICINAL PLANTS ON EGG HATCHING AND JUVENILE MORTALITY OF THE ROOT-KNOT NEMATODE, Meloidogyne incognita In Vitro
Cold pressed commercial seed oils of castor bean (Ricinus communis) colocynth, (Citrullus colocynthis) jojoba, (Simmondsia chinensis) and moringa (Moringa oleifera)at three concentrations (S, S/2 and S/4) showed nematicidal activity against egg- masses, free eggs and second stage juveniles of Meloidogyne incognita in vitro experiments.Egg hatching and juvenile mortality were significantly (P ≤0.05) influenced by tested oil, concentration and exposure time. Colocynth and jojoba oils gave a relatively higher effect followed by moringa oil while castor bean oil was the lowest effective one. Percentages inhibition in hatching when 5 fresh and uniform size egg-masses or 100 free eggs were separately exposed to the standard solution of colocynth, jojoba, moringa and castor bean after 7 days post treatment were 89.7 (63.8), 88.8 (54.4), 79.8 (52.5) and 43.4 (41.2)%, respectively. Egg hatching inhibition was inversely proportion to the dilution of the tested oil. On the other hand, as exposure time increased from 1 to 7 days after treatments, ovicidal effect of the tested oils was obviously increased at all the tested concentrations in treatments of egg-masses while the opposite was true in treatments of free eggs. Statistical analysis (P ≤ 0.05) showed that egg-masses were more sensitive to the tested oils compared to free eggs with all the tested oils at the three concentrations. Similarly, the tested oils were found to be significantly (P ≤ 0.05) effective against second stage juveniles of M. incognita. Among which, jojoba was the most effective oil followed by colocynth and moringa while castor bean was the lowest toxic one. The highest value of juvenile mortality was detected with jojoba at the standard solution, 7 days after exposure (48.6 %) followed by colocynth (43.0%) and moringa (31.0%) while castor bean (17.4%) was the lowest toxic one. Juvenile mortality was dependent on the concentration and exposure time also. Generally, in vitro treatments revealed that the tested oils displayed nematicidal effect against egg-masses, free eggs and juveniles of M. incognita. Further studies are needed under greenhouse and field conditions.

BIOLOGICAL CHARACTERISTICS OF TWO PREDATORY INSECTS PREYED ON Bemisia tabaci (GENNADIUS) UNDER LABORATORY CONDITIONS
Laboratory experiments were carried out in Plant Protection Research, Institute, Dokki, Giza, Egypt, Sharkia Branch to evaluate the efficacy of larval and adult stages of the predatory species Coccinella undecimpunctata L. and Chrysopa septempunctata Wesmael, when reared on Bemisia tabaci (Gennadius) at 261°C and 705% RH. Coccinella undecimpunctata larva consumed a total average of 563.95 whitefly individuals during its four larval instars. The predator female fed on a total average of 5633.95 individuals during it's longevity (46.15 days). The total average number of eggs laid per female was 1035.65 eggs, with a daily rate of 32.98 eggs. The predator adult male consumed a total average of 3295.75 individuals during it's longevity (30.60 days). The neuropteran predator, C. septempunctata larva consumed a total average of 2207.00 individuals during its three larval instars. The predator female fed on a total average of 3314.00 whitefly individuals during its longevity (43.80 days). The total average number of eggs laid per female was 780.50 eggs with a daily average rate of 35.24 eggs. The predator male consumed a total average of 2066.50 whitefly individuals during it's longevity (32.35 days). The results assured the predation activity of these predators when reared on whitefly and they can be recommended for using them as biological control agents for controlling Bemisia tabaci.

INFLUENCE OF DIFFERENT PEST CONTROL AGENTS ON SOME BIOLOGICAL ASPECTS OF Chrysoperla carnea (Stephens)
Four different pest control agents (Beauveria bassiana (Balsam), orange oil, neem oil, and pyriproxyfen) were evaluated at 0.5, 1 and 2 of field recommended concentrations (FRC) for their effectiveness on the biological aspects of the 2ndlarval instar of Chrysoperla carnea (Stephens) under laboratory conditions of 26 ± 2°C and 65 ± 5% RH. Taking into consideration the relative potency at the LC25 and LC50 levels, the obtained results showed that the neem oil was the highest effective agent against 2nd larval instar of C. carnea, recording the LC50 value of 10.61 µg / ml solvent, while B. bassiana was the lowest effective agent recording the LC50 value of 396.99 µg /ml. The means of larval duration were 6.83, 7.33, 6.50, 5.51 and 6.60 days, for B. bassiana, neem oil, pyriproxyfen, orange oil at 0.5 FRC and control, consecutively. While the means of pupal duration were 8.33, 7.33, 8.00, 7.00 and 8.50 days, for the same pest control agents and control, respectively. The maximum percentage of cocooning (100.00%) was recorded when larvae of the predator were fed on treated aphid nymphswith B. bassiana at all tested concentrations, and fed on neem oil and pyriproxyfen at 0.5 and 1 FRC, as well as control larvae. Meanwhile, the minimum value of 75.00 % was noticed when the larvae were fed on treated aphid nymphs with neem oil or orange oil at 2 FRC. Obtained results cleared that the highest mean of adult emergence of C. carnea (60.00 %) was recorded for larvae fed on treated aphid nymphs with orange oil 0.5 or 1 FRC. Whereas, the lowest one (20.00 %) was noticed in the case of larvae reared on treated aphid nymphs with pyriproxyfen at 2 FRC. Generally, control larvae exceeded other tested pest control agents in adult emergence, showing 70.00%. The maximum of fecundity, fertility, and hatchability percentage (324 eggs, 86.04 and 91.22%, respectively) when the larvae of the predator were fed on untreated aphids. On the contrary, the 1 RFC pyriproxyfen resulted in the minimum of fecundity and fertility showing 12.00 eggs and 50.00 %, successively. On the basis of the obtained results, it was obvious that the tested pest control agents (B. bassiana, orange oil, neem oil, and pyriproxyfen) at the highest concentrations are not considered to have an environmental safety profile on C. carnea. We suggest that the use of the tested pest control agents might be useful in combination at the low concentrations with releaseof C. carnea larvae in integrated pest management (IPM) programs.

CONTROLLING CABBAGE FUSARIUM WILT (YELLOWS) USING TOPSIN M AND SOME COMMERCIAL BIO-FERTILIZER PRODUCTS
Cabbage is one of the most widely cultivated vegetables in Egypt; Fusariumwilt causes significant crop loss in quantity and quality of most vegetable crops. The most frequency and isolated fungus from cabbage roots growing at Faquose District, Sharkia Governorate, Egypt was Fusarium oxysporum, followed by Verticillium albo-atrum. As for pathogenic activities of Verticillium albo-atrum and Fusarium oxysporum isolates on cabbage plants (cv. Balady), Fusarium oxysporum isolate No.5 gave the highest wilt disease severity. Host range of the tested Fusarium oxysporum isolate 5 revealed that cabbage (cv. Balady) was the only infected host. Field experiments were conducted to study the effect of Topsin M70%, Microbin, Rhizobactrin, and Weed-Max (blue-green algae extracts in powder phase) and Oligo-X algae (blue-green algae extracts in liquid phase) on vegetative growth (head diameter and stem height), total yield and wilt disease severity on cabbage (cv. Balady), during the two winter growing seasons of 2015 and 2016 in Sharkia Governorate at Faquose District. Results showed that both head diameter and total yield were increased by Topsin M70% and Microbin application followed by Weed-Max as well as Oligo-X, but the lowest one was Rhizobactrin compared with control. Also, wilt disease severity was decreased without significant effect on stem length. Regarding the effects of applied treatments on biochemical changes in cabbage plants (cv. Balady) under field conditions, all tested treatments reduced the activities of polygalacturonase (PG) and cellulase (CX) enzymes as well as, increased total phenols and total chlorophyll compared with control. In this respect, Topsin M70% and Microbin followed byWeed-Max as well as Oligo-X were the most effective treatments in reducing the activities of PG, CX and increased total phenol contents compared with Rhizobactrin treatment and control.

IRRIGATION MANAGEMENT FOR MAIZE CROP IN SANDY SOILS
Laboratory experiments were carried out at the National Irrigation Laboratory of Agricultural Engineering Research Institute (AEnRI), ARC, Dokki, Giza to test the performance of trickle irrigation. The emitters were tested and calibrated under different operating pressure (0.50, 0.75, 1.00 and 1.25 bar). All measurements were done according to ISO 9621 for evaluating drip flow rates. Also, the emitter flow variation, emotion uniformity and coefficient of variations were measured. In sandy soils, deep percolation, decrease in retention of moisture, compost condoner, rice straw and polymer were added to improve the physical properties of soil for keep water along time. Maize grows best on fertile and well-drained loamy soils. Proper management of inputs particularly irrigation water using modern technology is essential for maximizing production and for providing high return to farmers. This study were done for management of maize crop in sandy soil with three types of emitters (GR, antiroot GR and T-tape). While fields experiments were carried out during the agricultural season 2014/2015 at El-Husien farm in Alexandria-Cairo desert road. In harvest stage, ears were counted in all lines and weighted to know the yield. This study were done for management for maize crop in sandy soil with three types of emitters (GR, antiroot GR and T-tape). Compost condioner, rice straw and polymer was added to improve the physical properties of soil for keep water along time. Field results showed that antiroot GR emitter was the highest productivity with compost (3762 kg/fad.) whereas stalk lengh was 1.9 m and diameter was 37mm and has 17 leaves. The lowest productivity was antiroot emitter with polymer which valued 990kg/fad., and stalk lengh was 1.5 m and diameter was 35 mm and has 14 leaves. The middle in productivity was t-tabe with compost (2354 kg/fad.) and stalk lengh was 1.77 m and diameter was 35mm and has 15 leaves. Using compost with t-tape sub-surface drip system give good yield but using compost with antiroot GR sub-surface drip system give the best yield. Using compost with antiroot GR sub-surface drip system give good yield but using compost with antiroot GR sub-surface drip system give the best yield. Using polymer with antiriot GR sub-surface drip system give the lowest yield value.

EFFECT OF MILK TYPE ON CAERPHILLY LIKE CHEESE QUALITY
Caerphilly cheese is a British Welsh cheese originally processed from cow's milk and similar in its characteristics with Ras cheese, the most popular hard cheese variety in Egypt, which needs three to six monthes to sharp flavour. However Caerphilly cheese this period can be shorter than 3 weeks to reach the same organoleptic properties of Ras cheese. To process that variety under the Egyptian conditions, three types of milk processed into Caerphilly cheese as the following, 100% cow's milk, 100% buffalo's milk and mixture(cows: buffalos' 1:1). Resultant cheeses were chemically, physically, microbiologically and sensory evaluated at zero time and throughout the repining period. Results indicated that, cow's milk gained higher quality cheese with low yield (12.91%) while, buffalo's milk gave harder and harsh cheese with higher yield (15.80%), as well as, mixture milk gained medium yield (13.01%) and the highest score of sensory properties (78/100) in fresh cheese and (88/100) after the 45days of storage period compared with other treatments. Cheese made from buffalo's milk obtained the highest value for each of total solids, fat, ash and total protein when compared with other treatments either in fresh or after 15 days of ripening period. Cheese made from mixture milk had the lowest total counts of all types of cheese microfloura either it was fresh or after 15 days of storage. Moreover, mixture milk cheese had the best rheological properties [Adhesiveness (g), Hardiness (N), Springiness (mm), Cohesiveness (Ratio), Gumminess (N), Chewiness (J) and Modulus (g/mm)] among cheese treatments.So, from these results it could be recommended to process Caerphilly cheese from mixture from cows and buffalo's milk to obtain the best characteristics and medium yield.

EVALUATION OF ANTIOXIDANT AND ANTIMICROBIAL PROPERTIES OF Opuntia ficus-indica, SEEDS AND PEELS EXTRACTS
The biologically active compounds isolated from plants are known to be efficient as antibacterial and antioxidants. The antioxidant and antibacterial activities of total phenols and flavonoids drived from the petroleum ether, ethyl acetate and ethanol extracts of Opuntia ficus-indicaseeds and peels were performed using DPPH and modified Kirby-Bauer disc diffusion technique against gram-positive bacteria (Bacillus subtilis) and gram-negative bacteria (Serratia marcescens), respectively. In the present study, it is demonstrated that, both alcohol and ethyl acetate extracts show the best antioxidant and antibacterial activities than the petroleum ether extracts. This is consistent with the results of the chemical analyses of both extracts.

DIETARY COMBINATION OF VITAMIN E, SELENIUM, AND ZINC EFFECT ON THE REPRODUCTIVE EFFICIENCY OF NILE TILAPIA (Oreochromis niloticus)
This experiment was conducted to study the effect of combinations between 350 mg vitamin E with 120 mg zinc/kg diet, or 0.3mg selenium/kg diet as feed additives on the reproductive performance of female Nile tilapia (Oreochromis niloticus) diet for 144 days. Growth rate, average weight and number of eggs, egg weight, Relative fecundity, hatching percentage, survival rate of the fry and the concentration of follicle stimulating hormone (FSH) and luteinzing hormone (LH) in the blood serum at the different treatments compared to the control group. The results showed that the increase in the final body weight with vitam. E+Zn and vitamE +Se treatments was 141.80±0.92 and 142.00±1.15 g and body length was 20.60±0.06 and 20.60±0.06 cm compared to the control groups (136.00±0.92g, 20.30±0.05cm, respectively. The results of spawning efficiency showed an increase in average weight of eggs with vitam. E +Zn and vitam. E +Se treatments valued as much as 2.613±0.085 and 2.643±0.018 g and the number of eggs produced 453.33±18.05and 475.67±4.05 egg/female/ spawning compared to the control group (2.043±0.074 g and 365.67±15.81 egg/female/spawning, respectively). The relative fecundity of female’s recorded the highest value (3.20±0.12 and 3.35±0.03 egg/g of body weight) with vitam. E +Zn and vitam. E +Se treatments compared to the control group (2.70±0.12 egg/ g of body weight). On the other hand, the hatching percentage of eggs in treatment fed on supplementation diet with combination (vitam. E+ Zn) was higher (87.13±0.08%) than the other treatments. Fish fed diets supplemented with vitem. E+ Zn recorded the highest value of FSH, unlike the released hormone, which increased its concentration in blood fish in all treatments. The highest rate of increase in the body weight of fish larvae fed with (vitamin E +Zinc), the highest survival rate was with the fish group fed with a dietary supplement of vitam. E+ selenium).That is to say, female Nile tilapia (O. niloticus) feeding on diet combined with vitamin E, selenium and zinc had the positive effect on growth and reproductive performances in spawning season.

AN ECONOMIC STUDY ON EGYPTIAN ORANGE EXPORTS AND ITS COMPETITIVENESS IN THE INTERNATIONAL MARKETS
Foreign trade plays a major role in the implementation of the economic development programs, especially in developing countries. The goals and national orientation represented by export development which ensures the continuation of development efforts consequently are increasing employment opportunities, improving living standards of citizens and decrease the deficit in the trade balance, especially in light of rapid global changes. This changes requires the necessity of providing a competitive advantage for export commodities. That competitive advantage result from the interaction between economic growth stability. Moreover, the development of the private sector, education, productivity and efficiency, which affects the degree of integration in the global economy. From this standpoint, the agricultural sector plays an important role in developing the economy by its contribute in developing the exports. According to CAPMAS data the Egyptian orange is considered one of the most important exported fruits in Egypt trade, as its export value about 493.28 million dollars, which represents 11.3% of the value of Egyptian agricultural exports, which equal 4391.915 million dollars, during the average period (2014-2017). Moreover, Egyptian orange prices in the international markets are more competitive than prices offered by other international suppliers, therefore studying the most important foreign markets for Egyptian orange exports to know prevailing conditions in these markets, and determine the competitors and their price levels, which helps Egypt to push and increase oranges exports within these markets and then identifies the most important factors that can be focused on keeping the competitiveness of the Egyptian orange in the international markets.
