Abstract

In this research, use of mechanical power sources in the agricultural township of Shahriyar in Tehran province, was studied and strategies for improvement were provided. Data from field studies, literature and interview questionnaires were analyzed by using statistical software SPSS 21 in randomized complete block design and Duncan test method at 5% level for comparing means. In the region, 152 tractors, 3 combines and 4 self-propelled choppers were active. The region's tractors are able to perform operations for 1153.4 ha andin the township the executive capacity of 1,394 ha at the peak days is required.The available tractors are able to perform 83% of their executive power and it was found that 32 tractors and 13 migratory combines are needed to complete all agricultural operations. This shows a significant shortage of 32 tractors, which means that power has not been distributed appropriately. By taking suitable measures such as choosing proper tractors and matching implements and management practices can compensate for 14 tractors out of 32. Type of tractors and life of power source had significant effects on breakdown days of tractors with a direct relationship. Hour per horse power index of Universal tractors showed higher values which is an indication of better usage.
