The Decision Support System for Agrotechnology Transfer (DSSAT) Version is a software application program that comprises crop simulation models for over 42 crops. The most recent version is v4.8.2 (Check latest RELEASE here).
For DSSAT to be functional it is supported by data base management programs for soil, weather, and crop management and experimental data, and by utilities and application programs. The crop simulation models simulate growth, development and yield as a function of the soil-plant-atmosphere dynamics.

The experimental datasets are distributed with the DSSAT Cropping System Model (see dssat-csm-os GitHub repository) and contain at least one experimental dataset for each crop simulation model, including management, soils, and weather data.

Additional model-specific data files are included in the DSSAT source code repository under the "Data" folder. These include model-specific data for genotypes, pest, standard model data, code files, DSSATPRO files, etc.

The files in this repository can be combined with the files in the Data folder of the source repository to replicate the directory structure of the Windows installation of DSSAT v4.8.2 (e.g., with Genotype directory at the same level as the Alfalfa directory and the CDE files in the root directory).
To test your DSSAT-CSM model installation, execute the model from the Maize data directory using the following command line structure:
path+executable A UFGA8201.MZX
where UFGA8201.MZX is the name of a file containing details of a field experiment. This command should run the model for this particular experimnt and generate outputs for six treatments in files Summary.OUT, PlantGro.OUT, and other files.
If you are planning to use DSSAT in any reports or publications, please make sure to refer to the version number you used. The version and sub-version numbers can be found in the top section of your output files, e.g., 4.8.X (replace X with current version). In addition, please use the following two references for DSSAT and the Cropping System Model. Other related publications can be found in the Documentation section under DSSAT References and Model References.
