| Abstract | ||
| The tomato crop one family Solanaceae plants from self-pollinated vegetable crops, it comes in the first place among vegetable crops in terms of daily consumption as consumed either fresh or processed, and the yield of tomato and one of the vegetable crops that contribute to increased quite a bit in the agricultural economy in Iraq are give national income between (25-30) million a year to the all farm one, and it was possible to provide a yield to the consumer every day of the year through protected cultivation in plastic greenhouses or under the low-lying tunnels after it was seasonal crop production. The estimated cost function in the long run by using cross-sectional data of a random sample of farmers harvest tomatoes grown under tunnels low-lying (covered) They are (30), a farmer in the district of Kalar and representing (75%) of total farmers and (40) farmer's, a data analysis of crop adopted Cubism cost function as it passed the statistical tests and standard economic It was derived equation the average total cost for the long term and which were to determine the optimal level of production, which minimize the costs, which amounted to (6.977 tons), as well as been getting the optimum size of the farm, a (11.5) without, it was observed that the optimum space above the cultivated area rate actually and minimize costs should farmers crop that widen the size of cultivated areas to optimize its borders. The study of the economies of scale indicated that the crop growers have achieved a high rate of economies of scale reached 85% in most cases. This requires modifying their production levels as close to the ideal size. | ||
