The study is based on primary data collected from sugarcane growers to find out the affect of major farm inputs on the productivity of sugarcane in Tehsil Kot Addu (Punjab). The data was collected from 70 sugarcane growers during 2013 harvesting. The costs of land preparation, DAP, urea, irrigation, FYM, seed and labor for harvesting were the significant factors which affect on the proceeds of sugarcane growers. The results revealed that costs of land preparation, DAP and urea were highly significant at 1% level with positive coefficients 0.94, 0.23 and 0.76, respectively. The cost of FYM was significant at 1% level with negative impact on sugarcane productivity (-0.07). The coefficient 2 of multiple determinations R was 0.72, which designated that 72% deviation in the productivity of sugarcane was elucidated by all instructive variables and the 2 adjusted R was 0.71. To increase the output of sugarcane in the country, government may resolve the identified hurdles by providing subsidy on major inputs to raise the returns of sugarcane farmers.
