Abstract: Knowledge of the exact amount of water required by different crops in a given set of climatic conditions of region is of great help for planning of irrigation schemes, irrigation scheduling and also for mid term planning in case of mid season drought. The effective design and management of an irrigation system requires accurate estimation of crop evapotranspiration. The method selected for estimating evapotranspiration, however, should produce good result with a minimum of climatic data and also be applicable over a wide range of climatic conditions. The multiple correlation and regression analysis is generally used in hydrology to develop a relationship between three or more hydrologic variables by studying the dependence among them. The research work aims to arrive at a suitable empirical model for reasonable estimation of reference evapotranspiration for Nagpur region (Maharashtra State). In this research work the observations were recorded at Nagpur meteorologi!
cal station are used to calculate the evapotranspiration with the methods of Blaney-Criddle (BCL), Christiansen Equation(CNM), Hargreaves Method(HGM), Modified Penman method (MPM), Radiation Method (RAD), Thornthwaite Method (THW). The results of each method are compared with the results of the other.
