Abstract

Evapotranspiration (ET) is an important parameter for climatological and hydrological studies, as well as for irrigation planning and management. The FAO Penman-Monteith method (P-M) is the method recommended by FAO-56 for estimation of ETo over a wide variety of climatic situations over the world and it requires many types of climatic data. A study has been carried out to estimate the mean daily ETo characteristics of Parbhani in Maharashtra. The results showed that, the variation of average daily ETo values over the period (1982-2017) ranged from 3.45 mm day-1 (26th December) to 10.46 mm day-1 (29th May). The weekly mean ETo varied between 3.59 mm day-1 (52nd SMW) to 10.17 mm day-1 (22nd SMW). The total ETo is highest in the month of May (292.46 mm) followed by June (244.13 mm) and lowest in December (114.47 mm) followed by January (126.14 mm). It is observed that, there is progressively decrease in the total seasonal ETo from summer season (February to May) to kharif (June to September) and rabi (October to January) seasons. The average annual ETo was 2155.85 mm.
