If we talked about wheat crops, maize and sorghum are important food crops and involved in many important human food industries also enters as food for animals and poultry. Which requires the study of the importance of applying varieties technology and determine the extent to which they raise efficiency and unity of land and water in the cultivation of the most important field crops in Egypt and the province of Asyut To reach this year's goal was to identify the direction in the time of economic variables for crops under study and measure the impact of the use of modern productive varieties acres crops under study and measure the impact of the cultivation of varieties on the movement of the display function of the crops being considered as evident from the results that the taking of acreage under wheat, maize and sorghum incremental and uncertain statistically destination for both wheat and maize a general trend, As productivity took acres these crops trend years of incremental and uncertain statistically destination for wheat and uncertain statistically corn and decreasing of sorghum on the level of the province of Asyut, while taking the total production of these crops trend with an incremental, uncertain of statistical destination for both wheat and maize, decreasing sorghum. When examining the impact of the items on productivity  acres crops study shows the results of the study that for wheat cultivar surpassed sixth (1) in terms of cultivated area reaching about 58.8 thousand acres, while the cultivar surpassed BeniSuef (1) in terms of productivity, reaching acre productivity this product was about 20.1 ardebs, and for crop corn became clear superiority of a hybrid breed singles in 2030 in terms of cultivated area reaching about 21.15 thousand acres, also higher than the same class in terms of productivity, reaching acre yield of this product was about 22.3 ardebs, and for crop sorghum turned out superiority of Giza 15 in terms of cultivated area reaching about 33.5 thousand acres, while the cultivar surpassed in terms of productivity, reaching acre yield of this product was about 18.4 ardebs.
