Oil crops is one of the field crops for which she received human interest since ancient times and benefited from in different areas has prompted food and industrial most countries of the world importance to the expansion and development of agricultural and industrial to meet the increasing congestion of vegetable oils in the field of nutrition and manufacturing, increased quantities needed by Egypt of oil in recent years , which is a burden and a challenge to the Egyptian agriculture in this area, and can meet this challenge vertical expansion which leads to increase the amount of oil extracting, from vegetable Members, or horizontal expansion to increase acreage of oil crops, or Baloselten together increase the amount of output of oil, so targeted This study fundamental in the study of the technical and economic efficiency of some oil crops in Egypt and that by achieving the following objectives: 1 the geographical distribution of the cultivated area of oil crops in the study of the most important provinces of the Republic during the period (20092013) 2 the study of the evolution of both the productivity and economic indicators oily crops in Egypt during the period (1999-2013) 3 recognize the productivity levels of the elements contained in the function by estimating crop production function under study 4 the study of the relative importance of the terms of production costs and oil crops during the period (1999-2013) and the impact of each on the total production of crops under study 5 the study of the relative importance of the element of capital, compared with the element of work to study crops in Egypt during the period (1999 2013) The 6 Determination of economic derivatives of the function production costs and an estimate of the technical and economic efficiency of a crop of indicators subject of the study. The study found the following: That cultivated sunflower crop area has taken a trend Tnagosaia is a confirmed statistically significant at the level of significance 0.05 was estimated at 1.532 thousand acres, or the equivalent of about 4.83% of the annual average amounting to about 31.69 thousand acres during the period (1999-2013) this has reached coefficient specifically about 0.375, which indicates that 37.5% of the changes in cultivated sunflower crop area in Egypt due to the factors, which reflects the impact of the time element, while 62.5% of these changes are due to other factors not included in the analysis.
