| Abstract | ||||
| Feeding millions of poor people depend on wheat for both diet and livelihood, 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. Different sources of inorganic nitrogen fertilizers at recommended dose including urea (U), ammonium nitrate (AN), ammonium sulfate (AS) and calcium nitrate (CN) were applied to soil with foliar application of zinc (Zn) and/or boron (B). Several parameters of yield and yield components were recorded including vegetative growth, grain yield, total N, P and K content in grain and straw, total Zn and B content in grain and straw as well as quality parameters in grain and straw of wheat plant. The experiments were conducted in split plot design which consisted of the main plot (inorganic sources of nitrogen including U, AN, AS and CN as well as control) and sub plots (four treatments of micronutrient compounds including control, Zn, B, and Zn + B). The results revealed that Zn and/or B as foliar application of wheat plant under different sources of inorganic nitrogen fertilizers cause highly significant increases in all studied parameters of wheat grain and straw yields. Most of these parameters gave the highest values treated with ammonium sulfate as a soil application followed by urea. Foliar application of Zn or B as an individual effect caused high significantly increases for all studied parameters of wheat grain and straw in compared with the control (untreated). Combine foliar application of zinc + boron gave the highest values of all studied parameters of wheat grain and straw followed by individual Zn foliar application. Foliar application of Zn +B in addition to ammonium sulfate or urea results recorded the uppermost all studied parameters of wheat grain and straw. Therefore, it could be recommended that, under these experimental conditions, foliar application of both Zn and B in addition to ammonium sulfate followed by urea as soil application at recommended dose for wheat recorded the uppermost of vegetative growth (plant height and tillering height), yield components (weight of 100 grain and grain yield), N, P and K content in grain and straw, Zn and B content in grain and straw, chlorophyll a, b, protein content in grain and straw of wheat plant. | ||||
