This study was carried out to compare the data simulated by CERES-Maize model, which is included into the package DSSAT 3.5, to the data obtained from an experiment set up in the field for evaluating the influence of the depth and uniformity of water application by a conventional sprinkler irrigation system on the yield of maize crop. The treatments consisted of five water depths applied with two uniformities, that is, a high (>80%) and a low one (<70%). The CERES-Maize model showed a high performance, when simulating the productivity, leaf area index, and dry matter for most of the treatments. The model underestimated the crop productivity in those treatments where a high water deficit occurred. For the treatments receiving a water depth higher than that known to be appropriate, the values simulated by the model were slightly higher than the experimental ones.
