The study looked at how nitrogen fertilizer and planting density affect the yield and quality of a type of rice called Ganzhaoxian 52. They found that using 150 kg/hm2 of nitrogen fertilizer and a planting density of 20.0 cm×16.7 cm resulted in the highest yield of 6,525 kg/hm2. The amount of nitrogen fertilizer and planting density had a significant impact on the grain yield. Different combinations led to different populations of rice with varying characteristics. A population with an optimum leaf area index of 5.9 during the booting stage was best for high grain yield and quality, including the ratio of head rice, chalky rice percentage, and protein content.
