In order to give precise amount of irrigation through drip irrigation system, it is important to estimate the reference evapotranspiration (ETo) and crop evapotranspiration (ETc) for any crops. In this study, crop evapotranspiration (ETc) was determined for the Green chilli cultivated in the polyhouse and open field for the semi-arid climatic condition in Kumulur, Tamil Nadu, as it changes with the crop characteristics, climatic conditions and management practices. The chilli variety chosen was TNAU Hybrid CO1.The ETo value was determined by the Penman Mondeith method mentioned in the FAO-56 using ETo calculator. The ETc value was calculated by the soil water balance method as the change in soil moisture. The soil moisture data was obtained from the tensiometer readings. From the study, the ETc (mm/day) value of green chilli obtained was 2.2, 3.1, 3.2, 1.4in polyhouse and 2.6, 3.5, 3.6, 1.6 in open field condition for the initial, developmental, middle and end season stages respectively.
