Abstract: In order to explore the effect of combined application of organic fertilizer and chemical fertilizer on soybean yield, the author measured the yield and quality of soybean with 6 treatments under equal price conditions. The results showed that proper amount of organic fertilizer and chemical fertilizer could effectively increase soybean yield and improve soybean quality. When 120kg/hm2urea and 120 kg/hm2commercial organic fertilizer were applied, the soybean yield and quality were the highest, which was the most suitable soybean fertilization method in Linxian County, Shanxi Province.
