Reducing nitrogen fertilizer while maintaining rice yields is possible by using a fertilization model with 20% less nitrogen, 20% organic manure, and 30% slow-release fertilizers. This approach led to higher yields and better rice characteristics compared to traditional methods. The nitrogen use efficiency increased by 30.79% with this model. Plant height, tiller number, leaf area, chlorophyll content, and total plant weight all increased with this method. Additionally, the number of panicles, seed rate, grain weight, and overall yield were higher with the new fertilization model. This study shows that combining chemical fertilizer with organic and slow-release options can reduce nitrogen use while maintaining crop productivity.
