Abstract：In this research,four levels of nitrogen (N0,N90,N180 and N240) were designed,and the effects of nitrogen application amount on grain yield and nitrogen use efficiency of winter wheat Yannong 0428 were studied under the field condition with Jimai 21 as control.The results showed that the grain yield of Yannong 0428 increased with the increase of nitrogen application amount.Under the condition of the same nitrogen application amount,the grain yield of Yannong 0428 was obviously higher than that of Jimai 21.With the increase of nitrogen application amount,the nitrogen nutrient use efficiency and nitrogen partial factor productivity of Yannong 0428 decreased.And under the condition of the same nitrogen application amount,the nitrogen nutrient use efficiency and nitrogen partial factor productivity of Yannong 0428 were both higher than those of Jimai 21.Comprehensively considering the effects of nitrogen application amount on yield and nitrogen use efficiency of Yannong 0428,N180 treatment was more appropriate.
