In the current study, the effects of farming systems on potato production factors productivity were investigated in the 2011-2012. The data were collected using two stages cluster sampling and preparing 208 questionnaires submitted to farmers in the Koredestan and Hamedan Provinces. The efficacy of farming systems computed using dummy variable, and to select the best produce function, flexible and non-flexible functions were studied. Results indicated that production function Cobb-Douglas is better than the other tested functions. In addition, the effect of ownership farming system on production factors productivity was positive while the effect of other farming systems was found to be negative. Therefore, it is recommended that Ministry of Jahad-e-Agriculture encourage farmers to buy rental land and wells over the long-term period by giving low interest loans.
