Wheat plays an important role in the economy both at the level of production or consumption and affects the balance of trade in Iraqi.

As Iraq imported large quantities of wheat to meet the needs of domestic demand, despite the attention of government policies in this crop, including the price support and policy support policies, including the most input prices and output policy.

However, wheat production was characterized by volatile and low productivity rate per acre because of poor farmers in response to price policy or other policy support, such as financing and investment policy the high production costs one of the main determinants of the expansion of farmers in cultivated areas or raise productivity.

The most important of these costs is, seeds , fertilizer and operations of land preparation, harvesting and marketing etc.Therefore It was necessary to identify the structure of production costs and how close the farmers of the optimal level of production and the space .It try to shed light on the relationship between agricultural policies followed and costs.

The total cost estimate a function in the long term for wheat based on a random sample of data wheat farmers in Wassit province, in order to determine the optimal level of production..

The results showed that the optimal size of the production (196.529 tones) and this requires cultivation (230.038) acres.

It was noted that the cultivated area actually selected for the sample rate of up to (61.994) donums, This means that farmers can widen their cultivated area or the current output if they wish to use their resources optimally.

When you enter product prices in consideration optimal space that maximizes the more profitable the limits have been estimated (544) dunams.

They give up production as much (473.5 tons Knowing that this optimal size does not reflect the efficiency of the production because prices assigned by the state, and this means that there is waste in the use of economic resources by the farmers and the lack of economic efficiency in the use of optimally.
