| This research aimed to study the maize summer production economies of the Eastern province, and estimate the size of productive optimized for this crop, estimating profitability of corn summer maize, and to identify the most important problems facing the producers and which prevent continue to increase production of this crop.The study was based on preliminary data for the field study sample included 150 farms in Sharkia agricultural season 2014/2015. The study used the descriptive and quantitative analysis of the phenomena of economic variables under investigation for the analysis and presentation of results of the study methods. The average fixed costs (rental value) to harvest corn around 2,400 pounds per acre, representing 36.18% of the total costs, while the average total variable costs amounted to about 4233 pounds per acre, representing 63.82% of the total college costs. The average production per acre of corn harvest amounted to about 22.1 ardebs per acre (3.315 tons), an average price of about 330 pounds per ardebs, and therefore the main output of the crop of maize valued at approximately 7293 pounds per acre, and estimated net return per acre, gross margin per acre, the average cost of production per ton, product sidelines, the total margin per ton, the yield on the British investor, and net revenue per tonne of maize crop of about 1030.3430, 2001, the 14.13%, 1034.82, 1.16, 310.8 pounds, respectively, and as the optimal production volume of about 3.17 tonnes (ie about 22.64 ardebs), and amounted to the equivalent area of production optimization nearly 1,085 acres, on the basis that the average yield per acre of the sample amounted to about 3.315 tons (about 23.68 ardebs). While production which maximizes the yield size of (economic size) was about 4.09 tons, equivalent to about (29.21 ardebs), (equivalent area has reached about 1.233 acres, and average production costs amounted to about 1803.45 pounds per ton. One result of the production function analysis shows that the increase of human labor work, automated quantity of seeds, the amount of nitrogen fertilizer 1% of the level of current use leads to an increase in the marginal product physical at a rate of 0.294%, 0.056%, 0.159%, 0.254%, respectively, and estimates the total flexibility of productivity amounted to about 0.77, and this represents a case of increasing returns to scale in the sense that an increase in all factors of production, explaining contained in the form of a combined 1% leads to increased output is less than the one by (0.77%), and grade mix optimization of entrances production of seed and fertilizer nitrogen per acre amounted to 56.125 kg at a cost of 399.61 pounds, 3 Sharkia of nitrogen fertilizer at a cost of 600 pounds, and note down the cost of the seeds of a combination optimal for the actual cost by 29.58 pounds, while the cost of fertilizer nitrogen decreased Bkdar 280 pounds, decreased the total cost of these two elements by 309.58 pounds This means that the use of the optimal combination of the two elements of seed and fertilizer nitrogen availability to the farmer 309.58 percentage amounted to about 4.67% of the total cost of an acre. | ||||
