This study aimed to : Perhaps the most notable negatives in the agricultural sector lies in the deterioration of some degree of crop production. This has resulted in this situation many factors, most notably : the neglect of the agricultural sector and relatively attention to transfer surplus from this sector to invest in sectors Allazraaah, next to increase high population and the subsequent increase in the consumption needs of some of them, in addition to the price policy of agricultural characterized Paljzih and under which pricing some crops and left some without pricing, which led to the neglect and leave the crops, which are priced and the most important crop of wheat and rice and the trend to grow crops which are not priced like fruit, where the study aims at elevating the level of efficiency of economic performance for the production of wheat, rice, summer corn Chifah and expansion of production and by achieving some of the goals for the study of the situation productive current crop of study and development of the most important economic variables, monetary and study relied on the use of methods of statistical analysis, descriptive and Alkmyvy expression of economic variables, has adopted a study to get data from some official sources as handouts Agricultural Economics issued by the sector economic Affairs, Ministry of Agriculture and land Reclamation study includes four main categories in addition to the summary of Arabic and English and appendices and references in both Arabic and English, the first section includes a preliminary framework for the study of benchmark and review of previous studies of the crop study, eat Part II study of important. In Egypt and consists of three chapters of Part IV and the last address technical and economic efficiency of agricultural crops under study consists of four chapters and reach Studying important economic indicators for the agricultural ector in Savin Egyptian became clear that the production plant represents a productive activity prevailing in the agricultural production in the Arab Republic of Egypt, estimated cultivated area in Egypt about 8741122 and show that the crops of wheat, corn and summer rice represents the highest percentage in the cultivated area of the total cultivated crops It produces continents of Asia and Europe more than 50% of the world production of wheat, while the continent of Asia produces more than 90% of the global production of rice, and the American continent produces more than 50% of the global production of maize summerIt is the study of the economic structure turns out that the Egyptian Agricultural eastern province ranks the initial patch was about 375.76 thousand acres represent about 6.73% of the average area planted with wheat, while Western Province came in first place in terms of productivity Alfdanah out. Came the rice crop in the province of Dakahlia ranked first in terms of area and productivity Alfdanah reaching Messahnha about 456.90 thousand acres represent about 25.44% of the average area planted with rice, and the average productivity Alfdanah by 4.38 tons per acre. The maize crop in the province of Minya were ranked first patch amounted to about 278.35 thousand acres represent about 15.37% of the average area planted with maize summer, while the province of Dakahlia came in first place in terms of productivity Alfdanah where average productivity Alfdanah ardebs by 27.94 per acre and indicate the results of monetary indicators for the wheat crop that the costs of production per acre is increasing annually by 161.69 unds represents about 8.20% of the average annual amounting to about 1970.56 pounds and increased price farm by 13.81 pounds, representing about 8.93% of the average annual amounting to about 154.56 pounds while the net yield per feddan is increasing annually by 158.38 per acre represents about 10.29% of the annual average of about 1538.21 and ardebs pounds. And increasing the added value annually by 279.81 pounds per acre represents about 9.30% of the annual average of about 3005.84 and pounds while diminishing return on the pound invested annually by 0.01 pounds per acre represents about 1.33% of the annual average of about 0.75 and 5.84 pounds. For the rice crop Summer is increasing the costs of production per acre annually by 185.45 pounds and the increasing price farm by 72.49 pounds, representing about 7.35%, 986.38% of the average annual amounting to about The net return per feddan is increasing annually by 134.71 per acre represents about 7.09% of the average annual amounting to about 1898.81 pounds per acre and growing added by 34.93 pounds per acre represents about 6.49% of the average annual adult and about 537.40 pounds while diminishing return on invested pound of summer rice crop by 0.003 pounds per acre represents about0.4% of the annual average of about 0.75 and pounds per acre. Increased costs of production per acre of maize crop summer by 164.76 pounds represents about 8.61% of the average annual amounting to about 1911.75 pounds, and the increasing price farm by 12.49 pounds, representing about 9.45% of the average annual amounting to 132.06 pounds per ardebs and net yield per feddan by 153.27 per acre is about 11.50% of the annual average of about 1332.56 and pounds per acre Enma diminishing return on invested a pound by 0.03 pounds per acre represents about 4.35% of the annual average of 0.68 pounds. Has confirmed that a significant increase statistically significant at the 1% level of significance for the study of crops. The results of the production function to crop the study to a positive relationship between both the average value of production per acre of crops, the study by and between the value of production inputs following workers’ wages, and the banks public Ballnsph wheat crop, and the wages of animals and the price of piety and the rent for the rice crop summer and between the eighth seed for the crop maize Chifah IT is the study of the relative importance of the terms of production costs came clause in the rental value provided the first night workers’ wages and working robot and chemical fertilizer, respectively. The value of flexibility costs about 1.81 for the rice crop, which confirms the existence of efficiency in the production of rice crop and may be due to the use of appropriate methods in the cultivation of this crop and providing the requirements of production through agricultural cooperatives in these areas prices official in order to achieve an increase in total output. While the value of flexibility costs 0.74 maize crop Chifah, and amounted to 0.54 for the wheat crop means that the producers of the maize crop Chifah and wheat do not use their resources efficiently and therefore must be re-regulate the use of resources to get to use them efficiently and thus access to the volume of production optimization first and then try to access the size bulks for-profit. Recommendations : In the light of previous results and raise the level of crop production study (wheat, rice maize), the study recommends that the importance of each of the following :
1- horizontal expansion in the cultivation of wheat crop through the reclamation and cultivation of desert lands new or follow the structures of new crop is working to increase the cultivated area ment and work on the expansion in the production of maize crop for the existence of a comparative advantage to Egypt in its production so as to reduce the import of this crop. And cultivation of high-yield varieties of Alerzalty take a short time in the ground to provide water for him and of course the increase in productivity required for the benefit of the national.
2- Ensure thresholds for Sarmhasil (wheat, rice, maize summer) with announced before planting dates well in advance so that is guided by producers when making their decisions productivity, which may encourage producers to expand the cultivation of these crops. Thus increasing production and at least import from abroad eases so the burden on the State Treasury.
3- The need to activate the role of agricultural extension and national campaigns to improve the productivity of crops, the study by working to provide information and guidance relating to agricultural production and marketing in order to stimulate the expansion of farms in agriculture.
4- modified agricultural policy and crop composition and consider crops of wheat, rice, maize and summer in order to cope with high population growth and reduce the large gap between production and consumption, in addition to working to provide incentives to producers (the farmers) through the support of production requirements or provide the price of supplying high to work to increase the margin Profit.
5-The need direction to fix the prices of the product and production requirements with their counterparts representing the world and the opportunity cost of the national economy, both for production or its requirements and that under conditions of full competition in the market.
