The continuous cultivation of particular piece of land by farmers with little or no measures to improve the soil condition has seriously affected the productivity of the farmers in the study area. The study was on production function analysis and profitability of sorghum-Groundnut intercropping system in Doma Local Government Area of Nasarawa State, Nigeria. A multi stage sampling procedure was adopted in the research; Primary data were collected with the use of structured questionnaire administered on 80 respondents on their socio-economic characteristic, inputs and output, cost included and the revenue realized. Simple descriptive statistics, Gross margin and regression analysis were the analytical tools used in analyzing the data. Labour made the highest proportion of the total variable cost while Agro-chemical has the lowest proportion. The gross margin and return per naira invested were found to be N198,949.92 and N3.72. Thus these positive values show that sorghum-groundnut intercrop was profitable. The result showed that the regression model form had the best fit to data, with 0.652.meaning that 65% of the variation in sorghum-groundnut outputs was accounted by the variables included in the model. The finding also shows that F-test value of 40.075 is significant at 1% indicating goodness of fit. Labour had positive regression coefficient indicating direct relationship with the output. Pest and disease, High cost of inputs and storage problem were identified as major constraints to sorghum-groundnut intercropping in the study area. Therefore, it is recommended that capacity building on improve intercropped technologies be promoted as soil management and risk minimization.
