Abstract
In order to determine the effect of foliar fertilization and mineral nitrogen fertilizer levels on growth, yield and its components and grains quality of maize hybrid single cross 131 (SC 131), two field experiments were carried out at the Experimental Station Farm, Faculty of Agriculture, Mansoura University, Egypt, during 2014 and 2015 seasons. To reduce mineral nitrogen requirements by using foliar fertilization treatments as a new trend in fertilizing maize. Each experiment was carried out in a strip-plot design with four replications. The vertical plots were assigned with foliar fertilization treatments. While, the horizontal plots were occupied with three mineral nitrogen fertilizer levels. The results showed that foliar spraying three times with the mixture of GA3 at the rate of 50 ml + AA at the rate of 500 ml + YE at the rate of 2000 ml/200 liter water/fed produced the highest values of all studied characters in both seasons. Maize plants fertilized with 100 of the recommended dose (120 kg N/fed) resulted the highest means of all studied characters in both seasons. It can be concluded that foliar fertilizing maize hybrid SC 131 with the mixture of GA3 at the rate of 50 ml + AA at the rate of 500 ml + YE at the rate of 2000 ml/200 liter water/fed three times after 30, 37 and 44 days from sowing in addition mineral fertilizing with 96 kg N/fed in order to maximize productivity and grains quality and reduce production costs and environmental pollution under the environmental conditions of Dakahlia Governorate, Egypt.
