The study looked at how using a mix of chemical fertilizers and organic manure affects soil and rice yield over time. They tested different combinations of nutrients on a rice field for many years. The results showed that using both types of fertilizers together improved soil quality and increased rice yield. The soil had more nutrients like nitrogen, phosphorus, and potassium, and the rice plants grew better. The best results were seen when a mix of inorganic fertilizer and organic manure was used. This shows that balancing different types of nutrients is important for improving soil health and crop yield in a rice-wheat farming system.
