The study aims at estimating internal rate of return for the cultivation of date palms project in the new lands to encourage small investors and young graduates, to adopt projects of sustainable agricultural development under the assumption of change revenues and invested costs of the project. Also, explaining some productivity and economic indicators to produce dates in Egypt. The study showed that palm area, number of fruitful palms, palm productivity and the total production of dates annually increase at significant rates during the period of 1996 - 2010. The most important regions producing dates are Behera, Ismailia, 6 October, Aswan, New Valley, Matrouh and Noubaria zone. The most important cultivated varieties are Zaghloul, Samani, Meghal and Siwei. The study indicated that internal rate of return in the new lands as in Northern Sinai, Matrouh and the New Valley reached 28%. It was observed that decreasing total revenue up to 25% with increasing investment costs up to 25%, the internal rate of return is not less than 18%. So, cultivation of date palms is economically a profitable project. Thus, this project contributes to the horizontal agricultural expansion, reducing desertification, encourages some industries related to palm cultivation, creates new jobs, increases date export opportunities to overseas markets and increases agricultural income. Also, profits gained by young graduates are sufficient to pay annual premiums of received loans in addition to the interest of these loans, so that the left return is enough for their livelihood.

The present study was carried out in the desert valley (wadi) Abu Salam (63 Km.) east of Berber city, RiverNileState, and in the nursery of the Faculty of Agriculture, NileValleyUniversity. The autecology and biology of major desert specie, Handal (Citrullus coloynthsis), were studied. The study area (Wadi Abu Salam) was divided into three sections; upper, middle and lower. The soil was classified as sodic soil and contained a high percentage of clay in the upper section, equal percentage of clay and sand in the middle section and high percentage of sand in the lower section. The distribution of Handal plant in the wadi area was investigated. In the first season, it was only detected in the middle section (0.60-0.72 plants/m2). In the second season, the plant was distributed in the three sections of the wadi (1.46-1.66 plants/m2 for the upper section, 0.27-0.49 plants/m2 for the middle section and 0.3-0.4 plants/m2 for the lower sections).The rate of photosynthesis increased during the first stage of growth to reach its maximum (2.2-2.34 gm/day) during the 8th week from the start of germination, then started to decline till it reached its minimum rate (0.10-0.12 gm/day) at the maturity stage in both seasons. Plant roots growth started at a low rate, then, increased with plant development and became equal after 7 weeks from germination. After that, it decreased until it reached its lowest rate at the stage of maturity.

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.

The study amid to investigate the stability of production and Egyptian exports of onion and analysis of production policy of the crop. This is to show the economic effects of taxation and the support of the crop on the production and the comparative advantage of the crop to redistribute the Egyptian exports of onions so as to increase the value of exports of the crop. The results of the analysis indicate that values of nominal protection coefficient of Tradable output, nominal protection coefficient of Tradable input were, 0.90, 0.93 and 0.90 in 2010 year, respectively indicating that producers did not obtain the real prices of their production  which turned to the form of support to the consumer. On the other side, theDomestic Resource cost was 0.20 in the year of 2010 indicating the comparative advantage in the onion production. Results of stepwise multiple regression of the factors affecting the Egyptian exports showed that feddan productivity, the farm price and export price of U.S onion have statistical significant effect on the quantity of exports with F value being 17.82 the above factors contribute at 86% of the total factors affecting the onion exports during the study period (1995-2010). The results of linear programming showed that a minimum limit of Egyptian exports of onion to the importing countries, is necessary so as to the Egyptian exports of onion do not lose any foreign markets which, in turn, increase the value of onion exports by 44.64% compared to the current value in order to take advantage of importing the promising markets of onion crop, such as Saudi Arabia, Iraq, Jordan, the Netherlands and Italy.

This study presents the Mallophaga and Anoplura lice which affects farm animals (camels sheep and goats), a local area east of the Saudi Arabia of different ages, races, classes. Study the classification of lice were recorded as using the optical microscope and electronic scanning. The study shows scanning electron microscopy micro-structure of the species: Bovicola(Damalinia) ovis, Linognathus africanus and the study showed the installation of a portfolio of head lice, and the distribution of filament head, chest and abdomen, as shown over the centuries, the difference in the form of remote sensing and Swallows in the sexual lice, the first study in this area.

Field trials were conducted during 2005 and 2006 seasons at Minofia governorate to evaluate the effect of planting date of three cowpea cultivars on their infestation rate with cowpea pod borer, Etiella zienckenella. For each cowpea cultivar planted at each tested date, the numbers of bores and larvae were counted in green and dry pods as well as in dry seeds and the means were obtained to estimate the degree of insect infestations. Results indicated that, regardless the planting date in both seasons, Kream7 was the highest resistant cultivar to insect infestation followed by Kaha1 and then Kafr El Shikh1. On the other hand, regardless the cowpea cultivar, the rate of insect infestation was greatly reduced at the early plantation. Thus, selection of Kream7 cultivar and early  plantation could be involved in reducing E. zinckenella infestation and subsequently increase the cowpea yield. These studies clearly demonstrated that several non-insecticidal approaches have great potential for cowpea pod borer  Etiella zinckenella  management. These approaches include some of integrated pest management strategies which can effectively prevent or reduce infestation

Fusarium wilt disease is one of the major plant diseases that affect tomato production. The effects of neem (Azadirachta indica) and willow (Salix babylonica) aqueous extracts on fusarium wilt disease in tomato seedlings were investigated. Four weeks old tomato seedlings were treated with 10% of either neem and willow aqueous extracts and then infected with Fusarium oxysporum after 4 days of treatment. The results showed that the percentage of disease incidence was increased in non treated tomato seedlings in time dependent manner and reached the maximum level (65%) after 6 weeks of infection. Treatments of tomato plants with neem and willow aqueous extracts reduced the percentage of disease incidence to the level of 25.5% and 27.8% after 6 weeks of infection respectively. The results show that infection of tomato seedling with Fusarium oxysporum led to many morphological and biochemical changes including, reducing the growth of tomato shoot and root, increasing the level of lipid peroxidation and marked increase in the activities of antioxidant defensive enzyme i.e. POX, CAT, and SOD. Treatment with neem and willow aqueous extracts significantly exhibited a growth promotion of tomato shoot and root in infected or non infected seedling. Moreover, application of neem and willow aqueous extracts with fusarium, significantly reduce the level of lipid peroxidation and induce high activities of antioxidant defensive enzymes after 3 and 7 days of infection. Electrophoretic pattern of POX demonstrated that Fusarium oxysporum caused up regulation of several POX isoenzymes. It could be concluded that neem and willow aqueous extracts reduced the disease incidence of fusarium wilt in tomato seedlings by increasing the activities of antioxidant defensive enzymes and decreasing the level of lipid peroxidation.
