Description

Crop growth models are computer programs that compute daily growth of corn and soybeans based on daily weather (max/min temperature, rainfall, solar radiation) and management practices (planting date, variety, population, fertility, irrigation). During the past two years, we have undertaken several projects to validate a soybean and corn growth model in Iowa. These projects include baseline validation, yield prediction, and use of models to study spatial yield variability. We also have a project to evaluate the CROPGRO-Soybean model on several farms in Iowa. In this paper, we discuss several current projects which use crop growth models to evaluate crop response to management in Iowa.

Use of Crop Models to Evaluate Crop Management
