Nutrient supply is the most limiting factor next to the water for crop production. Sustaining rice production has become a great challenge, particularly in areas where rice productivity declines in spite of following recommended nutrient management practices. Nutrient management by integrating organic sources of nutrients along with inorganic fertilizers may play an important role in improving and sustaining rice productivity moreover, chemical fertilizers will play a major role as these contribute about 50% to the increase in food grain production for ever increasing population 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 have comparatively low in nutrient content, so larger quantity is required for plant growth.
