The study looked at how adding nitrogen, sulphur, and zinc to rice fields affects the yield and quality of the rice. They tested different levels of these nutrients and found that adding more nitrogen, sulphur, and zinc increased the amount of rice produced. The best results were seen with 180 kg of nitrogen, 40 kg of sulphur, and 10 kg of zinc per hectare. These nutrients also improved the protein, starch, and amylose content of the rice, making it better quality.
