ABSTRACT
In a study at KNUST weather station, the crop co-efficient values at initial, development, mid-season, and late season stages of ABONTEM MAIZE (hybrid variety) were determined as 0.42, 0.98, 1.05, and 0.32, respectively. These locally determined values of ABONTEM hybrid maize compared favourably with those recommended by FAO. The corresponding FAO values are 0.4, 0.80, 1.15, and 0.70. The FAO values are average values and recommended for a wide range of locations, but those determined by this study are location specific. Another reason may be the use of specific variety of hybrid maize in this experiment. However, locally determined values are preferred to standard values (FAO values) in estimating location specific crop evapotranspiration. The crop water productivity for the ABONTEM maize was found to be 3.42 kgm-3 as compared to some reported values of 1.1-2.7 kgm-3.
