the study aims to Search evolution of the Indicators to productivity and economic for Crops of wheat, maize, rice during the period (2000-2014) And analysis the effect of government intervention in production for the period (2012-2014)،The results indicate that average annual to cultivated area each them estimated at 2,9، 1,8، 1,5 million Feddan, respectively, As it turns out it increases annually by about 72,35، 32,05 thousand Feddan, represent about 2,50, 1,24 percent of the annual average area of wheat and maize, And that the area planted with rice characterized by relative stability, and this may be due to government intervention in determining the cultivated area. The annual average productivity per Feddan for study crops , Wheat, maize, rice, estimated at about 2,6, 3,38، 4 tons each, respectively, It was found that all a study crops was characterized relative stability, Annual average of total production of a study crops have been estimated about 7,7, 6,1،5,8 million tons, each for which respectively, the annual average for Farm price of study crops have been estimated around 1579، 1237،1356pounds per ton, respectively,It was found that is increasing annually about 156، 89، 121 pounds per ton represents about 9,86، 7,23، 8,94 % the annual average farm price. The total return amounted to about 4242، 4246، 5386 pounds per Feddan It increases annually by about 553,7 ،466,95 ، 539,2 pounds Represents about 13,05,11، 10,01 percent of the annual average from total income, the average total cost was around 290, 2881، 3305 pounds per Feddan, and is growing annually at about 282,4، 270,8 ، 292,7 pounds per Feddan represents about 9,71 ، 9,40 ،8,86 % of average total costs the average net return per Feddan was around 1333، 1371,2081 pounds and is growing annually at about 271,3, 196,8، 243,3 pounds,represents about 20,35، 14,35, 11,69 percent of the annual average net return. Nominal Protection Coefficient estimate for wheat crop was about 1, 07, indicating that the state provides support to producers of wheat, while the Maize and rice crops, has been estimated 0, 64 ، 0,43 indicating that producers bear the implicit taxes by the state٠Nominal Protection Coefficient estimate for Production requirements to the three crops valued at less than the one undivided, which indicates that the government provides clear support for imported inputs, which estimated at 0, 26, 0, 24 ، 0,27 % from the value of inputs. Effective Protection Coefficient for Wheat ، maiz, rice, crops estimated at 1,15, 0,61, 0,41 respectively, which indicates that there is effective protection to producers of wheat,While maize and rice producers bear implicit taxes, Comparative advantage coefficient estimated at 0,67, 0,56, 0,24% which indicates a comparative advantage to Egypt in the three crops production.
