Introduction The existence of mixed cropping particularly, legumes and cereals such as cowpea and maize among small scale farmers of W. Africa savannah has long been identified. 52-60% of small scale farmers in N. Ghana are involved in intercropping using OPV. (MOFA, 2010)
4
Introd. cont. Introduction of hybrid maize which is associated with sole cropping is a challenge in terms of intercropping to small scale farmers. The main objective was to determine cowpea effects on productivity and profitability of hybrid maize as an intercrop.

Conclusion Small scale farmers can maximize yield when intercrop hybrid maize with either of the cowpea types. With commercial producers sole cropping is advisable
