The African yam bean (
Sphenostylis stenocarpa Hochst ex A. Rich
) is a
leguminous crop found in the Volta Region of Ghana. Three expeditions were
undertaken in the region between September 1998 and March 1999 to investigate
the extent of cultivation and use of the bean as the basis for research into its
development and promotion as a major crop. Its cultivation is currently
localized around Nkwanta and Ho West Districts. It is grown as a minor crop in
mixed association with yam and cassava. It is used extensively in various
dietary preparations and has potential for supplementing the protein
requirements of many families throughout the year. Its current low status as a
minor crop means that this potential is largely unexploited. Research efforts
are required to improve its agronomic characteristics and promote its
cultivation and use as a major crop.
