The widespread development of Earth Observation (EO) systems and advances in numerical atmospheric modeling have made it possible to use the newest data sources as input for crop–water balance models, thereby improving crop water requirements (CWR) yield estimates from field regional scale. Satellite imagery weather prediction outputs offer high resolution (in time space) gridded that can compe...

Predicting the impact of future climate change on food security has important implications for sustainable production. The 26 meteorological stations’ data in study area are assembled from four global models under two representative concentration pathways (RCP4.5 and RCP8.5). maize yield, actual crop evapotranspiration (ETa), water use efficiency (WUE) were predicted by calibrated AquaCrop mode...

Abstract Optimization of water use for irrigation will only be possible with the adjustment management, which is directly related to correct estimate actual evapotranspiration crop. The present study aimed evaluate different mathematical approaches used in estimating a new soybean cultivar (BRS 7581RR) subjected deficit conditions. For this, ETa estimated by FAO56 Dual, Jensen and Hermann, Aqua...
