Evaluation of Maize Simulation Model (MSM2) by Lysimetric Data

In this paper, the MSM2 model was evaluated based on the field data measured at the agricultural research station of the University of Tabriz. The model was evaluated by data obtained from cultivated SC704 hybrid maize in a lysimeter. Comparisons between measured values of soil water content, maize evapotranspiration, grain yield and top dry matter with those predicted by the model showed the good estimation accuracy of the model. Also the comparisons between evapotranspiration estimation method of MSM2 model with conventional methods, considering single and dual crop coefficients, showed that the MSM2 model method had better accuracy than the conventional methods.
