摘要：A study was carried out to determine the crop water requirement of few selected crops for thecommanded area in the Shimoga Taluk in Karnataka state, India. The crops include cotton, maize for two seasons andsugarcane. By using the 10-year climatic data, Crop evapotranspiration (ETc) and Reference crop evapotranspiration(ET0) for each crop were determined using CROPWAT 8.0. The study shows that for both cotton and maize crops inRabi season effective rainfall is not sufficient to fulfil the crop water requirement. Hence irrigation requirement isneeded to satisfy Crop water requirement. But for the same crops in Kharif season effective rainfall is enough tocompensate crop water requirement. The crop sugarcane is a perennial crop for its crop period effective rainfall issufficient to compensate the crop water requirement.
