Question

How do you determine/select a good crop or climate models?

Answer 1

Crop model parameters are usually determined by iterative parameter adjustment and comparison with observed data from field trials; however, parameters estimated in this way are inaccurate because of the inherent experimental errors associated with field observation. Researchers now dissect model parameters into genetic factors to make cultivar-specific models. Crop modeling, which incorporates all (if possible) parameters affecting a trait into a model, can combine both genetic and environmental elements to predict phenotype
