Integrated Nutrient Management in Potato for Increasing Nutrient-Use Efficiency and Sustainable Productivity

Abstract

Sustainable agricultural production uses the natural resources to generate increased output and income, especially for low-income groups, without depleting the natural resource base. In this context, integrated nutrient management (INM) integrates the use of all natural and man-made sources of plant nutrients in an efficient and environmentally benign manner to increase crop productivity without sacrificing soil productivity for future generations. Sufficient and balanced application of organic manures and inorganic fertilizers is a major component of INM in potato. The integrated use of organic manures, chemical fertilizers and biofertilizers in potato was found encouraging not only for increasing tuber productivity and nutrient-use efficiency but also for improving soil fertility and sustaining crop productivity at high level.
