I examined the impact of improved cowpea technology on women farmers which was introduced by the Promoting Sustainable Agriculture in Borno State, (PROSAB), project which was implemented from 2004 to 2009 in Southern Part of Borno State, Nigeria. The specific objectives were to identify the changes in income as a result of using improved cowpea varieties by the respondents, analyze the impact of the improved technology on the food security status of the respondents and identify the constraints associated with the use of improved cowpea varieties.
