Abstract
This work was carried out at Vegetable Private Farm at Bani Amer Village, Zagazig Distract, Sharkia Governorate, Egypt during the two successive summer seasons of 2017 and 2018, to study the performance ofteneggplant genotypes; i.e., Little Fingers (L.F.), Ping Tung (P.T.), Antigua(An.), Aswad (As.), Japanese White Egg (J.W.E.), Apple Green (A.G.), Rotonda Bianca Stumata di Rosa ( R.B.S.),Korean Red (K.R.),Black Oblong(B.O.)and Black very Long(B.V.L.);underthree intra- row plant spacings, (30, 45 and 60 cm). The ten cultivars were evaluate in clay soil and surface irrigation. The ten cultivars were evaluated transplanting R.B.S.and B.V.L.cvs.at 45 cm gave the tallest plants. Transplanting A.G. and K.R.cvs. at 60 cm increased number of branches and number of leaves/ plant without significant differences between each other the case of number of branches/plant in both seasons. Transplanting K.R. and B.O.cvs.at 60 cm increased leaf area and dry weight of leaves, respectively.However, transplanting R.B.S.cv. at 60 cmincreased both chlorophyll a, b and total chlorophyll (a+b) in leaftissues, While the interaction between transplantingK.R.cv. onspacing at 30 cm gave the lowest concentration of chlorophyll a,b,total (a+b) and carotenoids in leaftissues of eggplant in 2018 season. With respect yield and its components, planting P.T.cv. at 60 cm andB.O.cv.at 45 increased number of fruits/plant, yield/plant,respectively.While planting As.cv. at 30 cm increased average fruit weight and total yield /fad.In the 2nd season, planting K.R.cv.at 60 cm, B.O.cv. at 45 cm, B.O.cv.at 60 cmand B.O.cv.at 30 cmincreased number of fruits/ plant, average fruit weight, yield/ plant and total yield/fad., respectively.
