1 CERES-WHEAT MODEL Model Name/Host Institution/ URL CERES-Wheat
USDA Agricultural Research Service Domain/Objective Simulate wheat development and yield depending on environmental/climatic variables, plant genetics, and crop management. Assumptions Excluded soil salinity and aeration, catastrophic weather events, interactions with pests and toxics, affect of Phosphorous, Potassium and other micronutrients. Temporal/Spatial Scale Daily timestep, designed for a farm or regional scale. Policy at regional scale-crop production and resource conservation

2 Input Drivers: Cultivar Planting Density Weather Soil H20 Nitrogen Availability Management Data Key Outputs: Crop Growth Crop Development Crop Yield

3 Simulated and measured LAI and above ground biomass of Chamran sown on Nov. 22, 2003 in Ahvaz, Iran.
Simulated yield for different sowing dates in 4 locations in Iran. Comparison of simluated, observed, and predicted LAI in 2006 in Northern Beijing. Blue: Simluated, Red: Observed, Green: Predicted

4 (CHINA) (IRAN)
