Abstract
Two field experiments were conducted on the Agricultural Research and Experiment Center, Faculty of Agriculture Moshtohor, Benha University, Toukh Directorate, Kalubia Governorate, Egypt,during the two successive summer seasons of 2014 and 2015 tostudy the effect of four nitrogen fertilizer treatments, i.e. 40, 70, 100 and 130 kg N/fed. and foliar spray by five micronutrient treatments, i.e. Non-fertilized, Zn, Mn, Fe and Zn + Mn + Feon the growth traits, yield, its component and some chemical properties of maize(white single cross hybrid 2031). The experimental design was split plot design in four replications. The obvious results of this investigation can be summarized as follows: All traits of maize under study (plant height, No. of green leaves/plant and leaf area index at 100 days from planting, No. of ears/fed., ear length, ear weight, weight of kernels/ear, 100-kernel weight, kernels shelling %, biological yield/fed., grain yield/fed., stover yield/fed., harvest index %, kernels nitrogen uptake/fed., kernels protein yield/fed., leaf and kernel nitrogen contents, zinc, manganese and iron contents of maize leaves in the two seasons.) showed significantly increased by increasing nitrogen fertilizer rates, except, mid tasseling and silking dates significantly decreased with increasing nitrogenrates in the both seasons. Application of 130 kg N /fed significantly gave the maximum values of above traits. Results revealed that micronutrient foliar spray using Zn + Mn + Fe treatment was the most effective treatment forprevious growth, yield and its components traits of maize in the two seasons. Meanwhile, maize plants which foliar spray by singly Zn, Mn and Fe treatments significantly gave the highest values of leaf zinc content, leaf manganese content and leaf iron content, respectively in 2014 and 2015 seasons. The interaction between nitrogen fertilizer by 130 kg N/fed.and foliar spray by mixed Zn + Mn + Fe treatment significantly gave the greatest values ofmaize traits, i.e. plant height, No. of green leaves/plant and leaf area index at 100 days from planting, No. of kernels/ear, ear weight, weight of kernels/ear, biological yield/fed., grain yield/fed, kernels nitrogen uptake/fed.and kernels protein yield/fed.in the both seasons. It could be summarized that fertilization of maize field by 130 kg N/fed.and foliar spray by mixed of Zn + Mn + Fe to maximized grain yield/feddan.
