Water logging and low application efficiency are main problems inherent with surface irrigation. The methods were surface, surface drip and subsurface drip irrigation with three level of irrigation 100, 80, 60% of potential evapo-transpiration were compared and contour map of soil moisture patterns were analysed for corn in two times; one before irrigation, and other at 48 h after irrigation. The distribution of water in soil profile for potato crop by subsurface drip irrigation system (SDI) studied and it was observed uniform and more yield for all treatments. |
