![]() Water demand by corn was maximized around V18. Crop water use increased with leaf number progression. The model was previously calibrated for evapotranspiration predictions using eight years of daily evapotranspiration measurements from a USDA-LTAR experiment in central Iowa with corn grown under conventional tillage systems (Kimball et al., 2016).įrom planting to V6 stage evaporation accounted for 70 percent of evapotranspiration while from V6 to R6 plant transpiration accounted for the 70 percent of the evapotranspiration for a 200 bushel per acre corn crop (Figure 1). We used the APSIM model to calculate average evapotranspiration values for a central Iowa cornfield to provide information on crop water use and loss during the growing period.
