Comparative evaluation of eight simplified potential evapotranspiration methods against the FAO-56 penman–monteith benchmark in the Jayakwadi Command Area, Maharashtra, India: a seasonal and spatial analysis
Accurate estimation of reference evapotranspiration (ET 0 ) is fundamental to irrigation scheduling, crop water requirement computation, and hydrological modeling in semi-arid agricultural regions. The FAO-56 Penman–Monteith (FAO-56 PM) method, the globally recommended standard, demands complete meteorological...
