The researchers conducted a field experiment to study how different nutrient management practices affect the productivity of summer rice in Odisha, India. They found that using 75% of the recommended nitrogen dose along with 25% from vermicompost resulted in the best yield and nutrient uptake by the rice plants. This approach led to higher grain and straw yields, as well as increased uptake of nitrogen, phosphorous, and potassium by the rice. Overall, the study suggests that integrating vermicompost into nutrient management practices can improve the productivity and sustainability of summer rice crops in the region.
