Optimizing Nitrogen Application Boosts Early Rice Yield and Quality.
The amount of nitrogen used on early rice affects its growth and yield. Increasing nitrogen boosts seedling growth and leaf area, but reduces earbearing tiller percentage, maturing rate, and grain weight. However, at 180 kg / hm2, the number of panicles and grains per plant peak. The relationship between nitrogen and yield follows a curved pattern, with the highest yield at 180 kg / hm2.
