Abstract: [Objectives] To systematically study the effects of different nitrogen levels on the growth and nitrogen utilization of sugarcane in Guangxi.[Methods] Through field experiment and indoor analysis, different nitrogen application levels were set up to determine soil nitrogen content and sugarcane nitrogen content. The effects of different nitrogen levels on sugarcane yield, agronomic characters and nitrogen utilization were studied. [Results] The effect of nitrogen application rate on sugarcane yield showed a quadratic curve, and nitrogen application could significantly increase sugarcane yield, and the sugarcane yield reached the maximum when the nitrogen application rate reached 714 kg/ha. [Conclusions] With the increase of nitrogen application rate, sugarcane yield increased, but when it exceeded a certain range, the sugarcane yield decreased significantly.
