Researchers conducted a field experiment to find the best fertilization method for high rice yields of Gengxian No.1. They tested different ratios of nitrogen, phosphorus, and potassium and found that a mix of 46% urea, 17% calcium superphosphate, and 50% potassium sulfate led to yields exceeding 8,829 kg/ hm2. By optimizing the fertilizer amounts, they were able to create mathematical models that significantly improved tillering, spike formation, and overall yield of the rice cultivar.
