Abstract Ground water is the most reliable source for irrigation, quantum of which varies from place to place, rainfall, infiltration, geographical strata and surface ecology. The development of ground water in conjunction with surface within canal commands not only assures a reliable source of irrigation, it also helps in alleviation of water logging in the command due to excess seepage and unscientific water use by facilitating vertical drainage mechanism. The ground water resource needs to be developed in order to enhance area and timeliness of irrigation supply and overall agricultural productivity of land.
