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. The need of the hour is therefore, maximising the production per unit drop of water. Hence in the present day context, lot of emphasis is being given in improving the irrigation practices to increase the crop production and to sustain the productivity levels. Micro-irrigation is introduced primarily to save water and increase the water use efficiency in agriculture. Reduction in water consumption due to drip method of irrigation over the surface method of irrigation varies from 30 to 70 per cent and productivity gain in the range of 20 to 90 per cent for different crops. By introducing drip irrigation, it is possible to increase the yield potential of crops by three fold with the same quantity of water. All these emphasize the need for water conservation and improvement in water-use efficiency to achieve “More Crop per Drop of water”.
