The results indicated that human labour and seed were the chief components which significanty contributed in the gross income of large farms. While land, human labour, seed and bullock labour were underutilised and manure was over-utilised in respect of farmers having small holding. Further results indicated that reallocation of resources like human labour and seed and withdrawal of other resources like manure and machine labour will greatly increase the gross income of the farmers in cowpea cultivation. The study of returns to scale suggested that all farms should increase the gross income by reallocation of independent variables like machine labour and manure. Marginal value productivity suggested that farmers should increase the land, seed and human labour and minimise certain resources like manure and machine in cowpea cultivation. The average variation in gross income found in the study was 77.87 and 88.42 per cent for small and large farms, respectively.
