ABSTRACT
This review summaries the wheat crop growth, yield and quality response to moisture stress and nitrogen availability in rhizosphere. The high nitrogen demand for nitrogen (N) by the wheat crop enhances the grain protein accumulation that is a key factor for baking quality. Nitrogen is one of the important nutrients for increasing wheat production but still there is need to economize the optimum nitrogen rate under water deficit conditions. Water stress is the most important abiotic stress that adversely affects the crop productivity. Soil moisture significantly affects the nitrogen nutrition through its effect on nitrogen uptake, mineralization and losses through leaching, denitrification, and volatilization. This colimitation of both N and water underpins an approach for improving water and nitrogen use efficiency concurrently and thereby enhances the wheat productivity and quality.
