Abstract:
Nutrient supply to crops is the most limiting factor next to water required in irrigation for crop production. Nutrient management by integrating organic sources along with inorganic fertilizers plays an important role in improving and sustaining crop productivity. Chemical fertilizers contribute about 50% to the increase in vegetable and grain production of our country. Successful nutrient management can optimize crop yields, increase profitability and minimizes nutrient losses. Organic fertilizer improves physical and biological activities of soil but they are relatively low in nutrient content, so large quantities are required for optimum plant growth. Continuous use of inorganic fertilizers alone causes soil degradation, pH imbalance and environmental pollution. So the integrated nutrient management system is an alternative system for sustainable and cost effective management of soil fertility and crop productivity without affecting environment. Application of such combined nutrient sources improved okra fruit yield and other yield attributing characters thereby, providing a profitable income for farmers by practicing this kind of nutrient management system.
