The study looked at how different ways of managing nutrients in rice and greengram crops affected soil quality and crop yield. They found that using a mix of organic and chemical fertilizers led to better nutrient levels in the soil and higher crop yields, especially when using vegetable market waste vermicompost. Without any external nutrient supplements, the crops didn't grow as well. The best approach for both crops was using 75% of the recommended nitrogen dose along with vegetable market waste vermicompost.
