effect of leased and private farming systems on machinery and land size for farm mechanization of canola in fereydoon-shahr, isfahan, iran

this study investigated the effects of land size and two leased and private farming systems of machinery on economic efficiency and factors such as total production cost per hectare (ratio of total cost of agricultural inputs and operations to farm size), total income (ratio of product and byproduct value to farm size), yield (ratio of crop production to farm size) and degree of mechanization for irrigated canola farming in fereydoon-shahr in isfahan province in iran. the data was collected using questionnaires distributed to 239 participants. the statistical analysis was carried out using a factorial test. the results showed that the farming system had no effect on economic efficiency and total cost but had a significant effect (at the 1% level) on total income. this was more marked in the private farming system. the relationship between farming system, yield and degree of mechanization was significant at the 5% level. in the private farming system, the highest yield was obtained. results also showed that land size appeared to have a significant impact on economic efficiency, total cost, total income, crop yield and degree of mechanization. as land size increased, these factors also increased, except for the degree of mechanization, which showed an inverse relationship.
