GROWTH AND PRODUCTIVITY OF SOME EGGPLANT CULTIVARS AS AFFECTED BY DIFFERENT PLANT SPACINGS

Abstract

; under three 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 cm increased both chlorophyll a, b and total chlorophyll (a+b) in leaf tissues, While the interaction between transplanting K.R. cv. on spacing at 30 cm gave the lowest concentration of chlorophyll a, b, total (a+b) and carotenoids in leaf tissues of eggplant in 2018 season. With respect yield and its components, planting P.T. cv. at 60 cm and B.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 2 nd season, planting K.R. cv. at 60 cm, B.O. cv. at 45 cm, B.O. cv. at 60 cm and B.O. cv. at 30 cm increased number of fruits/ plant, average fruit weight, yield/ plant and total yield/ fad., respectively.
