A Review Paper on Enhancing Water Productivity and Yield of Drip Irrigated Onion using Deficient Irrigation, Fertigation and Mulching

Shrankhla Mishra, S. K. Pyasi

Abstract: Water is the most important and critical input in man?s life especially in agriculture. The pressure for the most efficient use of water for agriculture is intensifying with the increased competition for water resources among various sectors with mushrooming population. Water productivity and onion yield therefore, needs to be assessed through integrated practice of drip irrigation involves exposing plants to certain levels of water stress during either a particular growth period or throughout the whole growth season. The optimum level of production can only be obtained by conducting an economic analysis of cost ? benefit ratio of input and output.
