Integrated Nutrient Management

Not AvailableThe real challenge is to keep the pace of sustainable production under condition of natural resources should be used to generate increased output and incomes, especially for low income groups without depleting the natural resource base. Rice is a component of widely varying cropping systems. Rice-based cropping systems form an integral part of agriculture in India. Several intensive rice-based cropping systems have been identified and are being practiced by the farmers in India. Productivity of this soil has remained low and unstable owing to climate and soil-related constraints. Intensive agriculture, involving exhaustive high yielding varieties of rice and other crops, has led to heavy withdrawal of nutrients from the soil. Also imbalanced and indiscriminate use of chemical fertilizers has resulted in deterioration of soil quality or soil health. The basic concept underlying the principle of integrated nutrient management (INM) is to maintain or adjust plant nutrient supply to achieve a given level of sustainable crop production by optimizing the benefits from all possible sources of plant nutrients. It involves utilization of local sources and hence, turned out to be the rational, realistic and economically viable way of supply of nutrients to crops. So that, environmentally benefiting manner without sacrificing soil productivity of future generations. Application of organic manure in conjunction with fertilizer and inclusion of legumes gave higher yield, net income and benefit: cost ratio under rice based cropping system. INM practices also improved the soil quality of the soils to some extent. Integrated nutrient management relies on a number of factors including appropriate nutrient application and conservation and the transfer of knowledge about INM practices to farmers through extension personal. Thus, INM is the only way to restore soil quality and make Indian agriculture sustainable.Not Availabl
