The study looked at how using green manure and nitrogen fertilizer affects rice growth and soil health. They found that combining green manure with nitrogen fertilizer improved important plant traits like chlorophyll content and leaf area, leading to higher rice yields. The best results came from using green manure with a moderate amount of nitrogen fertilizer. This approach also increased the nutrients in the soil after harvest. Overall, using a mix of green manure and nitrogen fertilizer can help increase rice yields and keep the soil healthy.
