Taro was a tuber plant whose knowledge of production was still poorly presented by scientific research in Benin despite its importance in food security. This work aims to assess farmers' knowledge of taro production and conservation systems in 15 villages in three communes in southern Benin. The methodology consisted of participatory research through individual and group interviews. Answers obtained, lack of seed (31.44%) and diseases (31.44%) are the major constraints affecting taro cultivation in the study area. In addition, producers did not have any method of managing tubers after harvest. Other constraints include the existence of a traditional and unstructured seed system, the lack of a tuber management mode and the presence of diseases. An inventory of the problems encountered in this case the lack of quality planting material provides an alternative for seed production by in vitro culture techniques.
