The CERES-Wheat model was designed to simulate the effects of cultivar, planting density, weather, soil water, and nitrogen on crop growth, development, and yield. It was developed to be useful for prediction and control at the farm and regional level. These objectives partially dictated the level of detail of the model. The model is not principally intended to be an explanatory model for improving understanding of how the crop system works. The primary purpose is for predicting potential alternative management strategies and tactics that affect yield and intermediate steps in the yield formation process. It is also intended to be useful at the farm level for within year crop decision making and multiyear analysis for risk assessment. On a regional basis it is intended to be useful for yield forecasting and the analysis of various policy questions related to crop production and resource conservation.
