Abstract

In this research, the ENERGY RATIO for POTATO production in different levels of cultivated areas (lower than 1 hectare, between 1-5 hectare, and higher than 5 hectare) in the western Isfahan province (Fereidan and Fereidunshahr townships) was assessed and determined. For this purpose, a number of questionnaires were prepared and distributed among the POTATO producers of the examined region. The results show that the highest share of energy consumed was for chemical energy especially N FERTILIZER with average of 51% and the lowest one was for biological energy (human labor) with average of 2%. Also the effect of different levels of POTATO cultivation on ENERGY RATIO was found to be significant at 1% probability levels so that with increasing cultivation level from lower than 1 hectare to higher than 5 hectares. As with increase in cultivated area from lower than 1 hectare to higher than 5 hectare, ENERGY RATIO increased from 1.3 to 2.08. It also observed that CROPPING SYSTEMs had marked effect on ENERGY RATIO at 1% level of probability. Also it revealed that both tractor type and tractor ownership were significant in their effect on fuel consumption on a per hectare basis.
