Abstract
Research derives its importance from studying potatoes which vital in a basket of food consumption for Iraqi family, perhaps among the causes of low productivity of donum the bad relationship between the area and the volume of the resources. Therefore, the research targeted to ensure that there is a systematic relationship, between productivity and the optimal size of the farm, which explain return to scale achieved, The research depended on a stratified random sample included 205 farm from sweet potatoes farms in Al-Anbar governorate/Iraq for two seasons 2010,2011. The characteristics of sample society varied in a positive impact on local productivity between the weak impact of domestic work and experience of farmers and the strongest impact of the class of seed ,the region and paid work while the impact of capital balance a positive on productivity. It was to determine the level of optimum output and prices, which cover variable costs and fixed in the short term. It was found that the positive systematic relationship between productivity and the size of the farm. An estimated volume of optimum productivity (4.65) tons/donum for farm size (23.79) donums, therefore recommends to merge the small and medium-sized farms together enterprises that fall within the area of return to scale, which their numbers represent 92.7% of the farms in the sample, to reach optimum size to benefit from the advantages of mass production.
