Determination of comparative advantage and problems of oilseed crops in Fars province

Fars province is one of the main agricultural poles in Iran. It would be a main center of production and export of agricultural crops, if a suitable policy and planned investment be used in the agricultural sector. A delicate attention to the comparative advantage of field crops is an important aspect of economic planning. In the current research comparative advantage and problems of the oilseed crops production such as rapeseed, sunflower, safflower and sesame were studied in 2002-2003.To obtain the objectives of the research, two groups of indices were used. The first one included Net Social Profitability (NSP), Domestic Resources Cost (DRC) and Social Cost- Benefit (SCB) ratio. Absolute and relative power purchasing parity (ppp) price were used to determine the mentioned indices. The second one included Efficiency Advantage Index (EFI), Scale Advantage Index (SCI) and Aggregate Advantage Index (AAI).Based on the first group of indices and also absolute and relative ppp, rapeseed, sunflower and sesame had comparative advantage in production when Safflower had none. Based on the EAI index, rapeseed had comparative advantage in yield, but the other oilseed crops had no comparative advantage in yield. SAI was more than one for sunflower and sesame. It shows that there is more concentration for sunflower and sesame than other oilseed crops in Fars province in comparison to the whole country. AAI was also more than one only in sunflower. It means that sunflower had a more comparative advantage in the region than in the national average, but it was less for other oilseed crops.
