AbstractA field experiment was carried out on the soil of continuous cotton cropping in Xinjiang, and the effects of organic fertilizer and chemic fertilizer combined application on cotton dry matter accumulation, nutrients absorption, cotton yield and nitrogen use efficiency were studied. The results showed that organic and inorganic fertilizers significantly improved dry matter accumulation and nutrient uptake in the middle or later period of cotton. Compared with chemical fertilizer treatment, different ratio of organic and chemical fertilizers combined application maintained or increased cotton production, improved number and weight of cotton boll. This application method improved the efficiency of nitrogen, nitrogen recovery rate up to 28.2%～57.7%, partial productivity from 17.1% to 76.3%. In conclusion, the organic fertilizer and inorganic fertilizers combined application could not only make the cotton production stable, but also improve nitrogen use efficiency.
