A study on hybrid rice growth and yield found that closer plant spacings and higher nitrogen levels led to increased grain yield. The best results were seen with 100 kg N/ha applied at 20 x 10 cm spacing, which produced the highest grain yield of 92.1 q/ha. This spacing also resulted in more effective tillers per square meter and quicker panicle emergence compared to wider spacings. Overall, the study showed that plant spacings and nitrogen levels significantly affected rice yield and growth, with closer spacings and higher nitrogen levels leading to better outcomes.
