Two field experiment using maize were conducted at the Experimental
Station of the Agriculture Research Center in Tag El-Ezz, Dakahlia Governorate, Egypt, during the
growing seasons of 2016 and 2017. Eighteen treatments were arranged in split-split block design
, which were the simple possible combination between three sources of organic
manures (control, FYM and chicken manure) as main plots and three sources of antioxidants in foliar
way (control, ascorbic acid and salicylic acid) as sub plots and two levels of proline as foliar
application (without, 50 ppm) as sub-sub plots.
. The results indicated that, the highest mean values of
vegetative growth (plant height, fresh, dry weight of flag), chemical content of flag leaf
(chlorophyll a, b, total, proline), quality (N, P and K % in grain, straw and cobs, fat, ash and
protein%), yield and its components (cob length, no. of grain/cob, 100 grain weight, grain yield
ton/fed, straw yield ton/fed and cobs yield ton/fed of corn) recorded with using chicken manure
. The highest mean values of all parameters under investigation
indicated with foliar application of ascorbic acid (100 mg l-1). Using of proline in foliar
way (50 mg l-1) increased significantly above parameters over the control. While,
moisture, total carbohydrates and fiber of decreased significantly with adding organic manure
and the highest values recorded with the untreated plant. As for the interaction effect, using
ascorbic acid as antioxidant and proline ( 50 mg l-1) under chicken manure application
recorded the highest values of all mentioned parameters.
