The study looked at how different ways of using nitrogen fertilizer affect the growth and yield of a specific type of hybrid rice. They tested different nitrogen application rates and methods on the rice plants. The results showed that increasing nitrogen fertilizer led to more tillers and higher dry matter accumulation, which increased the yield of rice. The best yield was achieved with an application rate of 10kg per 667m2. Adding fertilizer specifically to the panicles also boosted the yield, with the best results seen when the ratio of base and tiller fertilizer to panicle fertilizer was 6:4. Overall, applying earing fertilizer during the third stage of panicle differentiation period was found to be the most effective for maximizing rice yield.
