The study has been undertaken to determine and evaluate weekly and monthly reference crop evapotranspiration at Akola and Nagpur stations of Vidarbha region. Climatic parameters (Maximum temperature, Minimum temperature, Maximum relative humidity, Minimum relative humidity, Bright sunshine hours, wind speed)for 20 years (1983-2002 )were collected from agriculture meteorological observatory of Akola and Nagpur. Mean climatic data of 20 years (1983-2002) on weekly and monthly basis were used to determine reference evapotranspiration ( ETo) by FAO-56 Penman Monteith method (ETopm) accepted as...

The crop water requirements for the major Rabi crops viz. wheat, barley and gram were computed by Penman-Monteith method using computer program 'CROPWAT'. Distributary wise water supply and water demand was estimated for water balance analysis. The performance was evaluated using the adequacy and relative water supply indicators. These indicators were calculated for the ten distributaries for the 5-month irrigation period of Rabi season. Data ware collected from field and irrigation department. The analysis of results indicated inadequate and inequitable canal supply mainly at tail...
