To make students familiar with the crop consumptive use, Irrigation requirement of crops and irrigation methodologies implemented in farm.
Students would be familiar to find out crop consumptive use and water requirement of crops.
They also be able to design the irrigation channel and would be knowing about irrigation losses and measures to mitigate those loses
