| Abstract: | Field experiments were conducted to investigate the effects of combined application of fertilizer N and P on wheat yield and water use efficiency in different years of precipitation.Purpose of the study was to provide a theoretical basis of the combined fertilizer application model suitable to soil water conditions for the improvement of soil water in wheat yield.Results showed that(1) under the experimental conditions,both yield and water use efficiency with high N and P treatments were the highest in cont... |
