Abstract
Micronutrients on wheat Millions of people depend on wheat for both diet and livelihood. So, this crop could be considered a strategy food crop. Two field experiments were carried out at Abo-Zaher, Sherbin, Dakahlia Governorate, Egypt during the two successive winter seasons of 2013/2014 and 2014/2015 under alluvial soil conditions. This study performed to evaluate the different sources of inorganic nitrogen fertilizers at recommended doses as soil application, i.e., urea (U), ammonium nitrate (AN), ammonium sulfate (AS) and calcium nitrate (CN) with foliar application of zinc and/or boron as micronutrients. The previous treatments have been studied including their effects on vegetative growth, grain yield, total N, P and K content in grain and straw, total Zn and B content in grain and straw, pigment parameters in grain and straw of wheat plants.The experiments were conducted in split plot design which consisted of (1) main plot: five treatments with four sources of nitrogen fertilizers (75 kg N fed-1), i.e., control, U, AN, AS and CN. (2) Sub-main plot: four treatments of micronutrient compounds as follows: without application or control, Zn, B, and Zn +B. The effect of different inorganic N sources and micronutrients (Zn and/or B) either individual or interaction effects on vegetative growth (plant and tiller height) and yield (weight of 100 grain and grain yield) of wheat plants have been recorded during 2013/2014 and 2014/2015 seasons. Foliar application of micronutrients (Zn, B or Zn + B) of wheat plants under different sources of
