In 1982, an international group of agricultural and system scientists met at ICRISAT to define the minimum data set required to  simulate crop growth and development. The aim was to develop a solid foundation for research dealing with the soil-plantatmospherecontinuum, and to encourage strong links between scientists who study the biophysical and socioeconomic components of the agroecosystem. The scope of work was limited to 10 food crops, including four cereals (maize, rice, sorghum, and wheat), three grain legumes (dry beans, groundnut, and soybean), and three root crops (aroid, cassava, and potato). Barley and pearl millet were later added to the list. The conference participants wrote two reports. The first, Minimum Data Sets for Agrotechnology Transfer, was published by ICRISAT, and the second, Experimental Design and Data Collection Procedures: the minimum data set for systems analysis and crop simulation, was published by IBSNAT. The latter publication has been revised twice, and continues to serve as a guide for designing field experiments to validate models. Subsequently, the group decided there was a need to standardize the input and output format of existing crop models so that they all accessed a common data base and application program. This eventually led to a plan to combine the data base, crop models, and application programs into a Decision Support System forAgrotechnology Transfer (DSSAT).
