ABSTRACT
The study was attempted to examine the relationship of the yield of the sugarcane and various inputs used in its production by the sugarcane farmers in South-Goa district of Goa State during the year 2020-21. In all, 48 sugarcane growers were randomly selected from 16 villages of two tehsils in South Goa district. Cross sectional data were collected from sugarcane growers with the help of pretested schedule by personal interview method. Data were related to sugarcane outputs and inputs like machine labour, manure, fertilizers, irrigation and family human labour as resources. Cobb Douglas production function was fitted to the data. The regression co-efficient of irrigation under sugarcane was 0.091 followed by that of machine labour (0.068). In next order, regression coefficient of area was 0.651 followed by phosphorus (0.047). Regression co-efficient of potash, plant protection and family human labour were positive but non-significant. Regression co-efficient of setts was negative and non-significant. Marginal product of area under sugarcane was 257.32 q followed by that of plant protection (15.092 q) and machine labour (3.557 q). MVP to price ratio with respect to plant protection was 11.77 followed by area under sugarcane (1.79), machine labour (1.76), phosphorus (1.50), potash (1.42), irrigation (1.27). Hence, preference might be given to increase plant protection on priority basis in sugarcane cultivation. Optimum resource use of area under sugarcane was 0.75 ha, irrigation was 1781.84 m 3 and that of phosphorus and potash was 41.02 and 37.74 kg, respectively.
Key words : Sugarcane, resource productivity, resource use efficiency, optimum resource use
