Abstract

A study is carried out to determine the crop water requirement of some selected crops for the Ghataprabha command area situated in the state of Karnataka, India. Crop water requirement for each of the crops is determined by using 30- year climatic data in CROPWAT. Reference crop EvapoTranspiration (ET ) is determined using the FAO Penman Monteith o method. The crop water requirement and net irrigation requirement in the command area are determined for different hydrological years, viz., average, dry (P80), wet (P20), and normal rainfall (P50) scenario. The results of the modeling framework indicate that irrigation demand is highest during dry scenario and lowest for wet scenario whereas the water demand during normal scenario is well approached by that in average scenario. Kharif crops have lower irrigation water demand compared to other cropping criteria. Whereas the two seasonal crops require the highest water for cultivation compared to Kharif and Rabi crops. The proposed modeling framework recommends farmers to select most suitable scenario for better management of agricultural water resource.
