One hundred and twenty (120) of bambara groundnuts and cowpea growers were sampled basing on their wealth for primary data collection. Secondary data were collected through a desk review of publications from key organizations. Pre-tested questionnaires were used to interview farmers. Both descriptive and quantitative analysis techniques were used. Descriptive analysis included the use of means, percentages, ranges and other summary was done by using the Statistics Package for Social Science (SPSS).

The results also revealed that 42% and 43% of the household depend on bambara groundnuts and cowpeas for food during hunger periods respectively. The results indicates that bambara groundnuts and cowpeas are mainly produced by women, on average 97% and 95% of bambara groundnuts and cowpeas respectively are women. Regression analysis reveals that bambara groundnuts and cowpeas production is highly influenced by area under bambara groundnuts, area under competing crop, price of input. and market access and for cowpeas the production is influenced by cowpeas price, area under cowpeas, price of intercropped crop and market access. Lastly the result revealed the crops are important sources of house hold income, 73% of the respondent earn income from bambara groundnuts production while 37% of respondents earn income from cowpeas production.
