Abstract
Humic acid is natural biological organic, which has a high effect on plant growth and quality. However, the mechanisms of the promoting effect of humic acid on the morphological components, growth and yield parameters were rarely reported. In this study, the effects of soil application of humic acid on the morphological components and growth parameters of wheat under dry climate were explored. Randomized complete block design (RCBD) with five treatments of humic acid and replicated three time, T1=control, T2= 4.5kgha-1, T3= 6 kgha-1, T4= 9.5 kgha-1, T5= 12 kgha-1 and T6= 14.5 kgha-1. Findings of this study indicated that with increasing application of humic acid growth and yield also increases plant height (21.97%), spike weight (157%), leaf area (34.12%), grain spike-1 (93%), grain yield (49.36%) and biological yield (80.34), though pH of soil also increased. While; results of NO3-N and K were also significantly different under different level of humic acid and mean maximum were recorded in T6 (25% and 48%) in comparison of T1, T2, T3, T4 and T5. Conclusively; this study revealed that application of humic acid at the rate of 14.5 kg ha-1 could improve the growth and yield parameters of wheat and soil fertility.
