Abstract:
Two field experiments were carried out at Toukh El- Aklam, Village, El-Sinbelaween Station, Dakahlia Governorate, during 1989 and 1990 seasons to study the effect of four nitrogen fertilizer levels (0, 30, 60 and 90 kg N/fad), three foliar application time (after 30, 50 and two equal halves at 30 and 50 days from planting (DFP) as well as four foliar treatments namely (foliar x, Irral, Aziplex and Sicotree Zn) on growth, yield and grain quality of maize. Results indicated that the interaction between nitrogen levels, times of spraying and nutrients foliar application was significant, the maximum plant height, ear height, stem diameter, leaf area ear length, ear diameter, number of grain/row, 100-grain weight, shelling percentage, grain yield/plant, grain yield/fad and grain protein percentage. However, the minimum number of days to 50 % tasseling and silking, were recorded under the combination of 90 kg N/fad, and spraying Irral at the rate of 300 g/fad after 50 days from planting. In conclusion, the desirable growth characters of maize can be achieved through nitrogen application at the rate of 90 kg N/fad, spraying foliar nutrients after 50 days from planting and foliar Irral at the rate of 300 g/fad under the environmental conditions of El-Sinbelaween Center, Dakahlia Governorate.
