Data is put in by the modeler and is mainly experimental data.
The output data given by the model is predicted weight of leaves , stems, roots, pods, shells, seeds, LAI, SLA, root length density on a daily basis. Inputs and outputs are on a daily basis, while some internal processes such as development are calculated on an hourly basis. Validation procedures include independent data sets collected at the University of Florida, and various locations in the U.S.A. and at international sites. A very large collection of data sets is available from India. There are currently about 30 data sets which have been used for model validation.
