Abstract: 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 (0 , 50 mg l-1) 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 at the rate of (50 mg l-1) under chicken manure application recorded the highest values of all mentioned parameters.
