In order to understand the impact of different nitrogen application rates on soybean yield and economic benefits,the article set different nitrogen fertilizer application rates and analyzed the soybean yield and economic benefits of the experimental site in Peiqiao Town of Yongcheng City in Shangqiu.The results showed that applying nitrogen fertilizer had a significant increase in yield and economic benefits compared to not applying nitrogen fertilizer.As the amount of nitrogen fertilizer increased,both soybean yield and economic benefits showed a decreasing trend.When the nitrogen fertilizer dosage was 105 kg/ha,the soybean yield could reach 5 131.5 kg/ha,an increase of 64.16％compared to the control,and an increase of 9 633.6 yuan/ha in income.
