Economic Study of the Supply Response of the Oil Crops in Egypt

The nutritive vegetable oils considered from the oily crops used in human nutrition, and also the petit result of it which represented in the earnings considered forage for animals, hens, the peanut and sesame, sunflower and soybeans crops are considered the most important oily crops in Egypt as it represents about 12.38%, 6.69%, 3.74% and 3.18% from the total oily crops consequently in total of 25.99% and that as an average for the period (1990–2014) However the economic and manufacturer importance of the oily crops it doesn't have the sufficient importance as the grown space of these crops still limited as it doesn't exceed 0.45% of the average yielded space in Egypt during (1990 – 2012).                                  
So the research aims at achieving a lot of objectives such as studying the relativity importance of the oil yields and the oily crops in Egypt and studying the productive and economic indicators of the oily crops in Egypt and the statistical estimation of the significance respond of the oily crops in Egypt, the study reached to a lot of results such as the following:-                                                                                                   
-      The total space of the oily crops represents about 9.31%, 21.24%, from each of the yielded space and the summer paddies obtained consequently during the period (1990 – 2012).
It's shown also from the study that it takes a general direction reduced in an incorporeal statistical amount reached 19.73 thousand acre during the study period.
-      It's shown from studying the productive indicators for each of peanut and sesame crops that they took a general increasing direction in an incorporeal indicator amounted to 5.29,0.98 thousand acre of the yielded space, 0.019, 0.45 ton/acre for the acre productivity and 7.92, 0.75 thousand ton for the total production in Egypt consequently during the study.
-      It's shown also from studying the productive indicators for each of the sunflower and soybeans crops that they took a general direction reduced in an incorporeal statistical amount for each of the yielded space and the total production amounted to 1.36, 2.79 thousand acre consequently and 1.017, 2.72 thousand ton consequently, whereas the acre productivity of the two crops took a general direction increasing in an incorporeal statistical amount of 0.008,0.024 ton/acre consequently during the study.
-      The economic indicators of peanuts crop refer to that it took a general indicator increasing in an incorporeal statistical amount 27.28, 95.77, 178.16 pound/ton for the agricultural price, the average cost of the produced unit, the profit of the produced unit consequently, whereas it reached 391.31, 142.46, 248.85, 0.046, 0.045 pound/acre of the total revenue, the acre costs, net return of the acre, ratio of revenue to costs and the return of the invested pound consequently during the study.
-      It's noticed through the study of the economic indicators of sesame, sunflower and soybean that they took a general direction in an incorporeal amount increasing statistically reached about 310.55, 102.5, 106.03, pound/ton for the agricultural price and 189.16, 71.01, 63.54 pound/ton for the average cost of the produced unit, 142.5, 28.19, 62.3 pound/ton for the profit of the produced unit, 191.98, 112.81, 188.3 pound/acre for the total revenue, 109.55, 80.73, 106.68 pound/acre for the total costs, 82.23, 32.08, 90.28 pound/acre for the net return of the acre consequently during the study.
While the net return of the soybean crop took a general direction in an incorporeal amount statistically increased is about 0.02 pound/acre, while the sesame and sunflower crops took a general direction in a not incorporeal amount statistically increased, the ratio of revenues to costs for the sesame, sunflower and soybean took a general direction reduced and not statistically incorporeal during the study.
It's shown from the estimation of the respond of the show for the oily crops in Egypt which depended on the delayed distribution samples such as Mark Nearlove, Fisher, Solo, Georginson and Kedhy in addition to the other suggested samples, and the most important factors affecting the grown space of Peanuts and Sesame at the current year represented at the agricultural price and the grown space at the previous year and the acre productivity as increasing each of them by the unit amount resulted in  increasing the current grown space by the amount of 0.007, 0.001 thousand acre of the agricultural price 0.809, 0.312 thousand acre of the grown space, 118.8, 0.423 thousand acre of the acre productivity of the two crops consequently during the period (1990 – 2012).
It also revealed that, one of the most important factors affecting the grown space at the current year of the sunflower crop represented in the agricultural price and the grown space at the previous year with a delay period of two years and the total cost as increasing each of them by the unit amount resulted in increasing the current grown space by 0.006, 0.278, - 0.02, - 0.010 thousand acre consequently during the study, and it's noticed that there is an inverse relation between increasing the current space of the sunflower crop and the grown space with a delay of two years and that not agreed with the economic logic.
About the soybean crop it's revealed that the most effective factors on the current grown space represented in the agricultural price, the grown space at th previous year and the current costs as increasing each of them by the unit amount resulted in increasing the current total grown space by -0.003, 0.742, -0.004 thousand acre consequently during the study, and it's noticed that there is an inverse relation between increasing the current space of the soybean crop and the agricultural price which not agreed with the economic logic.
In accordance with that, the study recommends to the necessity of working on elicitation of new sorts to replace the old sorts to increase the productivity, reducing the costs by rationalizing the use of the production needs and making awareness campaigns for the farmers by the agricultural cooperative associations, modifying the oily crops to encourage the farmers on growing these crops.
