Recent data shows a declining performance in Egyptian foreign trade of agricultural sector especially by increased the Egyptian agricultural import, which leads to increase the deficit of agricultural trade balance. Agricultural processed proucts is consider one of main source of agricultural trade balance deficit. As a result, it is necessary to study the main factors affecting the Egyptian demand of foreign agricultura processed products to determine the most important factors and determine the possible solution in future. It is clear through the research resealt of the factors affecting the quantity of the Egyptian fats and oil imports, that their main factors are determined by the total production of the Egyptian fats and oil, the imports price and the consumption of oils and fats and in the total exports of USA from oil and fats. Moreover, it is obvious from the factors affecting the demand in Egyptian market that the price of the USA fats and oil is considered the main factor in most of these markets. Moreover the effect of free trade agreement and European Egyptian agreement were significant positive for increase the Egyptian demand of foreign oils and fats. So it is important to use some possible solution for decreasing these positive impact of these fators on Egyptian demand for foreign oils and fats for developing countries without being against the activation of these agreements. It is important to control the national consumption and increase the total production of oil and fats.

This study was carried out in Wadi EL- Technologia in Ismailia Governorate, Egypt, during 2010 and 2011 seasons. Washington Navel (N.O.), Valencia (V.O.) and Baladi orange (B.O.) trees budded on Sour orange (S.O.) and Volkamer lemon (V.L.) were grown in sandy soil under drip irrigation system from a well has salinty of (1100 ppm).This investigation aimed to study the effect of the two citrus rootstocks on vegetative growth, yield, fruit quality, leaf mineral content of the three studied scions as well as the effect of such scions on root system growth of both rootstocks. The obtained results indicated that, Volkamer lemon rootstock  recorded the highest significant values of vegetative growth, yield and fruit quality except  T.S.S% and ascorbic acid content . Sour orange rootstock gave the highest significant effect on values of leaf mineral content (N, P, K, Mg, Fe, Zn and Cu) however V.L. showed the highest significant value. while, Ca leaf content recorded insignificantly difference between both  rootstocks. Leaf Mn, content was significantly the highest with S.O. in both seasons. Root fresh and dry weight were the highest significantly with V.L. rootstock. From the showed result, one can recorded that V.O. scion significantly increased the vigour of V.L. root fresh and dry weight. While, B.O. scion showed significantly the lowest vigoure of V.L. root fresh and dry weight. On the other hand, N.O. scion gave a midiate result between V.O. and B.O. scions on root fresh and dry weight.

The study aims at researching the possibility of vertical expansion of wheat crop by increasing the total production of the crop from the same cultivated area by re-distributing the area of crop in different zones of the Republic according to its productivity and show the importance of feddan productivity in increasing total production of this crop.  The study showed that the increase in feddan productivity has an effect in increasing the total production, but its impact in increasing feddan revenue and the value of crop production was weak. It has been shown there is a possibility to increase the total production of wheat crop   by maximizing the economic efficiency of productive resources used in cultivating the crop about 2.09 % of the increase in the total production. The increase in the production of the crop estimated by 1118 thousand ardabs that valued at 99 million LE and save about 53 million cubic meters of irrigation water despite the stability of the cultivated area of wheat crop all over the Republic.  The study recommends reconsideration of the current area of wheat crop by expanding the areas of wheat crop in the governorates or the regions characterized by high productivity to achieve the economic efficiency in the use of the production agricultural resources dedicated for wheat planting, so that they can provide areas for wheat in low productive regions to other crops of high productivity in these regions and then relatively reduce wheat gap in Egypt.

Despite the increase in vegetable exports from 329 thousand ton in the year 2000 to about 3156 thousand tons in 2010, and the increase in vegetable local production from 14.8 million tons to 1019.5 million tons during the same period,the deficit in the agricultural trade balance has increased from $ 11 million in the year 2007 to about $ 18 million in 2012.However, it is noticed that exports of strawberries and artichoke the nontraditional crops, have increased from $ 2.2 million in 2002 to about $ 24.9 million in 2012. For this, the study endeavor to give special concerns to the two products particularly for their high average export prices which have tripled compared with potatoes and onions in recent years. The paper revealed that average exports of strawberries have increased to about 6391 ton and to about 32.6 thousand tons during the period 2005-2007 and 2008-2010 respectively. Belgian market absorbed about 19% and 23 % of the quantity exported during the two periods. Saudi Arabia imported about 11.3 % and 21.4 % of Egyptian strawberries. Egypt has a comparative advantage in producing strawberries as it came the second after Spain. Strawberries face strong competition and the penetration index was put at 0.002 and 0.779 during the two studied periods. This also noticed that Egypt has a relative price advantage compared with Holland, France, Belgium and Spain. For artichoke, the study shows a decrease of average exports from 14.8 thousand tons during the first period to about 11.7 thousand tons during the second period. Italian market absorbed about 64 % and 80 % of total artichoke. Egypt has a relative advantage in producing this crop compared with competing countries. Egypt also price advantage in artichoke compared with Spain, France, and Italy. The paper shows that determinants of total global demand of Strawberries as export to Saudi Arabia, relative price of Saudi price and export price of Egypt and Spain. For artichoke, the determinants were production in Italy, France export price in addition to production and price ratio in French market. The first equation in the econometric model shows that per head consumption of strawberries increases by about 0.95 % with the increase in local production. The second equation in the model shows that per head consumption in important imported countries increases with the increase of per head local production, exchange rate, the increase of per head income in Germany. The study shows that Egyptian –European partnership agreement has its positive effect on strawberries exports. The third equation in the model shows that per head local production has increased by about 0.02 % , 0.07 %  and 0.1% with the increase in per head  local consumption in the last year and the decrease each of per head production in Italy and Russia in the last year, respectively. As for artichoke, the study shows in the first equation of the model that average per head consumption has increased by about 1.01 %, 0.01 % and 0.1% with the increase in local production and the decrease each of artichoke exports and Egyptian price, respectively. The second equation in the model shows that per head Egyptian export in important imported countries with the increase by about 1.1% , 1.2% , 1.8% ,2.1% ,4.7% with the increase  each of export prices in France, Italy, Spain, exchange rate and per capita income in Germany , respectively., Per head of Egyptian export of artichoke has Also increased by about 0.97% , 0.2% with the decrease  each of per head consumption in Egypt and export price of Egypt , respectively . The study showed a negative effect of Egyptian European partnership agreement and SPS treaty on artichoke exports. The third equation in the model shows that per head local production has increased by about 0.01 % , 1.8 % , 1.4% and 0.38% with the increase in per head  local production in the last year and the decrease all of per head production in Italy , Russia and Greece in the last year , respectively.
