Abstract
The experiment was conducted to optimize the level of humic acid, zinc and boron for better growth, enhanced yield and grain quality of wheat crop cultivated under field condition. Growth characteristics, yield and its components, and zinc concentrations in straw and grain were analyzed under two application rate of humic acid (0 and 10 kg ha -1 ), three level of boron (B 0 = 0, B 1 = 2 and B 2 = 4 kg ha -1 ) and zinc (Zn 0 = 0, Zn 1 = 5 and Zn 2 =10 kg ha -1 ). Results revealed that application of Zn at 10 kg ha -1 and B at 4 kg ha -1 combine with humic acid (10 kg ha -1 ) significantly increased yield and its components (except flag leaf area under humic acid application), and Zn contents in straw. The maximum plant height, spike length and grain filling rate were recorded at Zn 2 and B 2 with humic acid application. Maximum grain yield was produced for Zn 2 and B 2 under humic acid application, which was associated with higher 1000-grain weight and biological yield. Maximum biological and straw yields were produced by application of Zn 2 and B 2 under humic acid fertilization. Maximum Zn contents in straw have been recorded for Zn 2 and B 2 under humic acid application, while maximum values of crude protein and Zn contents in Zn 2 and B 2 were statically same with Zn 1 and B 1 under humic acid application. Furthermore, the highest boron contents in grain were recorded for Zn 2 and B 2, and these values were statistically same with Zn 2 and B 1 under humic acid application. It is concluded that application of Zn 2 and B 2 in combination with humic acid could be a good agronomic practice to enhance the zinc content in straw and grain yield of wheat crop.
