Increased planting density and fertilizer boost rice yield and quality significantly.
Increasing nitrogen levels and the ratio of phosphorus and potassium can boost grain yield in paddy rice. Planting density affects the number of panicles per area, while fertilizer impacts the number of spikelets per panicle. The key factor for yield is the number of spikelets per area, with a focus on increasing spikelet number per panicle. Planting density correlates with panicle number, spikelet number per panicle relates to dry matter production, and dry matter production links to nitrogen absorption.
