The study looked at how different ways of growing rice and applying nitrogen affect the amount of rice produced. They found that using 180 kg/ha of nitrogen is best for all methods of cultivation. The best ratio of nitrogen at different growth stages varies depending on how the rice is grown. Some methods of cultivation can increase rice yield by adjusting nitrogen levels. In one area, a certain method of cultivation led to higher rice production. The amount of rice produced also depends on factors like temperature and light. Overall, adjusting nitrogen levels and cultivation methods can help increase rice yield.
