A systematic description of the CORNGRO model is presented, highlighting those aspects of the model which have not been reported earlier. The model was modified to better simulate the corn growth process and predict the final yields. The sensitivity of the simulation results to the input values of some important environmental factors were tested. The sensitivity analyses indicate that the simulation results of the model are moderately sensitive to the soil property curves, and highly sensitive to the input values of the daily potential evapotranspiration (ETP). Also, the plant growth parameters are more sensitive to the input values of daily ETP for adequate irrigation treatments than for deficient irrigation treatments.
