Sugarcane is one of the important commercial crops and plays a crucial role in the agro-industrial economy of India. The present study was undertaken on hundred farmers of sugarcane cultivation in Sant Kabir Nagar district of Eastern Uttar Pradesh. Based on the nature of data, Cobb-Douglas production function was used for estimation resource use efficiency of sugarcane cultivation. The results revealed that return to scale on marginal, small and medium farms were 0.812, 0.912 and 0.962 respectively which are less than unity. It means, sugarcane cultivation is characterized by decreasing return to scale and the Coefficient of multiple determinations (R²) were 82.50, 84.10 and 87.50 percent the variation of output by dependent variable viz. seed, irrigation, plant protection and manure and fertilizers. The marginal value productivity of seed, irrigation, plant protection and manure and fertilizers measure were considerably high on all size groups of farms except fertilizers and seed on marginal farms. It indicates that positive relation is further scope for increase in the investment to realize more return.
