DSSAT was initiated under the auspices of the International Benchmark Sites Network for Agrotechnology Transfer (IBSNAT) funded by the US Agency for International Development (USAID) from 1981 through 1992. The IBSNAT Project was headquartered at the University of Hawaii and the development team included crop modelers from the University of Florida, University of Guelph, University of Puerto Rico, Michigan State University, the International Fertilizer Development Center, and USDA-ARS. After termination of the IBSNAT Project development and advancement has continued because of the significant interest of the scientific community and public and private partners.
