Though Nigeria is blessed with vast land and human resources suitable to produce enough food for her teeming population, low productivity in crop production has constrained her food sufficiency effort; this however calls for crop production mixture expansion strategies. The study evaluates the economics of yam-cowpea intercropping in Obi Local Government of Nasarawa State, Nigeria. The specific objectives were to describe the Socio-economic characteristics of yam–cowpea intercrops farmers; identify the sources of fund; to estimate input-output relationship in yam-cowpea production in the study area; determine the cost and returns on yam–cowpea production; and identify the major constraints to yam-cowpea inter-cropping system. A multi-stage sampling technique was used to select 80 yam-cowpea intercrops farmers, farm input-output data were collected based on 2015 cropping season with the aid of a structured and validated questionnaire. The results revealed that 83.8% of the respondents were males; most of the farmers (76.4%) had formal education and majority of the respondents (77.6%) had farm size of 0.5 to 2 ha. The results further revealed that majority of the farmers (57.5%) got their finances from their personal savings. The double-log production function analysis reveals that the coefficient of multiple determination, (R2 = 0.908) indicated that 91% of the variation in the value of the output (₦/ha) was explained by independent variables. Yam sett and labour were found to be significant at 1% while agrochemical was found to be significant at 5% in increasing the value of the output. The gross margin analysis showed that Gross Margin (GM) was N25, 455.30 with return per naira invested of 0.11. The study also revealed that high cost of inputs, pests and diseases and inadequate capital were the major constraints to yam-cowpea production in the study area. The study recommended that inputs (yam setts and agrochemicals) supply at subsidized rate to farmers in the area should be enhanced. There is need to make funds accessible and available for the farmers in the study area through the creation of functional rural micro finance institutions.
