Yam mounds have been raised in a partially cleared agricultural field. Small trees have been left to supply support for climbing vines and to aid fallowing after the field has been used for several years. The hard work of forming the mounds using short-handled hoes takes place early in the dry season, after which mounds are planted with yam cuttings during the months of January-February. The vines grow throughout the rainy months of April to August, forming new tubers which are ready for harvesting in late August-September. Banda area, Dec. 1982.
