Water Use Efficiency (map) in Maize biomass in Ashanti region and Brong-Ahafo region in Ghana under three fertilizer application rates i.e., 4 kg/ha Nitrogen (current application rates); 45 kg/ha Nitrogen and 15 kg/ha Phosphorous; 135 kg/ha Nitrogen and 45 kg/ha Phosphorous, 1992-2010

Water Use Efficiency (WUE) for maize biomass in Ashanti region and Brong-Ahafo region in Ghana has been estimated under three different fertilizer application rates using crop model LINTUL5 embedded into the modeling framework SIMPLACE (Scientific Impact Assessment and Modelling Platform for Advanced Crop and Ecosystem Management. Purpose: To increase food production, identifying the regions with untapped production capacity is of prime importance and can be achieved by quantitative and spatially explicit estimates of Water use efficiency, thus considering the spatial variation in environment and the production system.
