Abstract.Thisstudydivulgedthecost-returnsanalysisbetweenimproveddualpurposecowpea (IDPC)varietiesandothernon-IDPC/localcowpeavarieties in Azir, Damboa town, Kuboa and Sabongari villages of Damboa local council, Borno State, Nigeria. Socio-economic stratification of the villages into Low Population Low Market (LPLM) and Low Population High Market (LPHM) on the basis of human demographic profile and proximity to wholesale market were the criteria adopted for selecting the villages for this study. A total of 150 cowpea farmers responded to the questionnaire instrument; administered between December, 2006 and February, 2007. Results of the budgetary techniques used show that adopters of IDPC varieties generate $386.01ha-1 as net income as against $248.37ha-1 for the non-IDPC adopters; proportional to 55.42% rise in net income per hectare of cowpea resulting from the impact factor of IDPC adoption alone. Similarly, farmers in Sabongari village realized the highest net income of $491.99ha-1 as against Azir the lowest net income of $247.21ha-1 across the four villages owing to demand factor; interplay between human population and proximity to wholesale market; both in favour of Sabongari but none in favour of Azir. In terms of ratios, farmers in Sabongari were adjudged as more lucrative across adopters’ category, socio-economic domain and villages respectively owing to higher return on sale ratio and lower operating ratio. Azir and Sabongari villages were found to exhibit potentiality for comparative cost advantage and comparative sales advantage respectively. Thus, the research concludes that an expansion path for cowpea is feasible if cultivation and sales are premised on cost and sales advantages.
