Abstract:

Three field cxperiment were carried out at Sakha Agricultural Research Station. Kafr El-Shcikh Govcrnoratc Egypt. Thc aim of this investigation was to study the cŒect of water stress, some maiie cultivars and ؟inc sulphate as foliar application on yield, yield components and chemical analysis in maize grains. The expcri mental design was split-split plot with lotir replications. The results could be summari,ed as follows: The average values of plants carried more than one car percentage. car length, car diameter. car weight. number of rows/ear. number of grains/row. 100-grain weight. grain yield per plant and per feddan significanth decreased by increasing the depletion of available soil moisture up to 80°/. in combined analysis. On the other hand, the percentage of late wilt disease significantly increased by increasing the depiction of available moisture, irrigation after 40% depletion in available water gave the lowest protein % and the highest protein yieldlfeddan. oil % oil yleld/feddan and zinc content in grains of maize T WC 310 cultivar gave the highest values of the percentage of plants earned norc than one ear, ear length. car weight. number of grains/row. IOU-grain weight. grain yield per plant and per feddan. protein and oil yicld/fcddan and ؟inc content when compared with the other cultivars, Gua 2 cultivar gave the highest percentage of infection with late wilt disease than other cukivars Whereas Karnak cultivar gave the maximum ear diameter, number of rows/ear, protein and oil percentage ingrains of maize The mean values of ear length, ear weight. 100-grain weight. grain yield per plant and per fcddan straw yield, protein yield, oil percentage and oil yicld/feddan were increased when received 0.3% zinc sulphate. but the other characters of yield components were not significantl affected, The mean values of infection with late wilt disease percentage significantly increased b increasing level of ‘inc sulphate up to 06% The interaction between خ W ( 110 with the application of 0 6% ؟inc sulphate gave the highest mean alues of 100-grain weight. grain yield per plant and per feddan Also the interaction bctw’cen imgation after 40/.depleuon in available water with T W C’ lB) and applying 0 6% ى.inc sulphate as foliar gave the highest mean talucs of number of grains/row protein and oil 4icldlfcddan Significant positite correlation values were detected between grain vield/feddan
