Irrigation water management is the process of planning and controlling the volume, frequency and rate of application of irrigation water in a strategic and effective manner to satisfy the water requirement of the crop. This involves applying water according to crop needs, holding ability and intake characteristics of the soil.
The overall results of proper irrigation water management are water conservation, reduced pumping costs, prevention of soil erosion, and reduced labour, improved quality of groundwater and downstream surface water and increased crop biomass yield and product quality.
