Scientists from across the world met from May 15-20, 2023 on the University of Georgia Griffin Campus to learn about the latest version of the Decision Support System for Agrotechnology Transfer (DSSAT) computer software program. The DSSAT crop modeling ecosystem helps researchers predict growth, development and yield of many cereal, grain legume, root, vegetables, and other crops in response to the genetics, weather and management (G * E * M). Since 2002, scientists, graduate students, and many others have met on the University of Georgia Griffin Campus for this international training program. This year, the 58 participants represented Afghanistan, Benin, Brazil, China, Colombia, Ethiopia, Georgia, Germany, Ghana, Guatemala, Haiti, Honduras, India, Iran, Israel, Malawi, Morocco, Nepal, Netherlands, Nigeria, Pakistan, South Korea, Sudan, Taiwan, USA, and Zimbabwe.
