ABSTRACT

In the present study, weekly meteorological data on rainfall, relative humidity, wind speed and cloudiness was collected from Indian Meteorological Department, Pune for Nagpur district. The probability analysis of rainfall was done by Weibull’s plotting position and expected rainfall amount at 50%, 70% and 80% probability were worked out. Rainfall curves at various probability levels were drawn. Values of reference evapotranspiration (ETo) were calculated on weekly basis by Modified Penman method and probability analysis for the same was done. Crop coefficient (Kc) curves were developed as suggested by Doorenbos and Pruitt. The crop water requirement (ET crop) was worked out by using Kc values of rice and ETo values at 70% probability. It was revealed that ETo and ET crop of rice (Kharif) was found to be 2125.69 mm 657.50 mm respectively.
