Cowpea

IITA releases non-GM high-yielding striga-resistant cowpeas (March 2009)

Resource-poor cowpea farmers in sub-Saharan Africa have seen their profits jump by 55 per cent thanks to improved dual-purpose cowpea varieties developed and introduced by IITA and its national partners in Nigeria. Paul Amaza, IITA Agricultural Economist, says that farmers who use traditional varieties earn about US$ 251 per hectare, while those who are growing the improved cowpea are getting US$390, or US$139 more, per hectare with proper crop management.
