Reasonable Nitrogen Fertilizer Management Improves Rice Yield and Quality under a Rapeseed/Wheat–Rice Rotation System

To determine the influence of N fertilizer management on rice yield and quality under diversified rotations establish a high-yield, high-quality, environmentally friendly planting technology, rapeseed/wheat–rice rotation system for 2 successive years was implemented. In those systems, conventional rate (Nc; 180 kg/hm2 in rape season, 150 wheat season) reduced (Nr; 120 were applied. Based an application three models applied, which ratio base:tiller:panicle 20%:20%:60% treatment M1, 30%:30%:40% M2, 40%:40%:20% M3. Zero used as control (M0). The results showed that, Nc Nr M3 produced increase yield. average yields 2018 2019 9.41 t/hm2 9.54 t/hm2, respectively. An peak viscosity, hot break disintegration, chalkiness achieved. Under panicle season higher 9.45 9.19 respectively, disintegration produced. Reduced rapeseed rapeseed–rice can be recommended to stabilize ensure high-quality production systems southern China.
