The Strengthening Partnerships, Results, and Innovations in Nutrition Globally (SPRING) project developed this farmer field school (FFS) curriculum to improve farming practices and increase aflatoxin-safe groundnut crops for better household nutrition. It was originally developed for the Ghana Ministry of Food and Agriculture’s agricultural extension agents to work with groundnut farmers in Northern Ghana supported by SPRING. The project trained agents to use the curriculum before they began facilitating their sessions with local farmers. While the content of the curriculum was designed to train farmers in the Northern and Upper East Regions where SPRING had been operating, it can be used for groundnut farmers throughout Ghana.
