Abstract

Evapotranspiration demands and trends were analysed for Jabalpur region in eastern Madhya Pradesh by assessing reference evapotranspiration (ETo), energy balance and aerodynamic components for 31 years (1983-2013). Analysis indicated multiple trends in annual ETo and annual aerodynamic component of ETo. In the first half of the study period, a clear decreasing trend was seen with 1994 and 1999 years having low ETo values. Later, the ETo started increasing and a high ETo of 1425 mm was observed in the years 2009 and 2010. Energy balance component has shown a negative trendwith the reduction in temperature and sunshine hours.Trends in five-year average ETo values indicated a reduction in kharif season whilethe EToincreased in rabi season. Present study highlights the necessity to understand ETo of the region before planning and management.
