Si application alleviates influence of some abiotic stresses on crop plants. Meanwhile, scarce information is avaiable about the significance of Si for helping the plants to overcome the injuries of N deficiency and herbicides pressure. Thus, two–year 2–field experiments were carried out in wheat. Experiment I involved three Si concentrations (Si0ppm, Si250ppm and Si500ppm) and two N levels(N100% and N50%). Experiment II examined four combinations of fenoxaprop–p–ethyl and Si: fenoxaprop–p–ethyl+Si250ppm and fenoxaprop–p–ethyl+Si500ppm (each either in sequence or in tank mixture), fenoxaprop–p–ethyl alone, hand weeding and weedy check. Under N deficiency (N50%), Si500ppm increased plant height as compared to the control. No significant differences in SPAD values were detected amongst Si concentrations under each of the two tested N levels. Si can partially alleviate negative N deficiency effect on wheat yield, causing its increase to level obtained under normal N supply. Si has no effect on weed biomass when applied with fenoxaprop–p–ethyl either in sequence or in tank mixing. The most promising treatment for maximizing wheat grain yield was the application of 100 kg N ha–1 (N50%) x fenoxaprop–p–ethyl+Si250ppm in sequence", which also, in the same time, means reducing both cost of crop production and environment pollution.

This research aimed to study the economical impacts of using different types of irrigation water to produce wheat crop, through economic analysis of crop production and its costs, in order to maximize the income of each unit of water. The sample of study was choosed from wheat farmers in El.Sharkia Governorate. The results indicated that the productivity of one feddan irrigated with fresh water and groundwater was 18.09 and 18.08 ardab/fed respectively. It was 17.72 and 17.11 ardab/fed. for land irrigated with mixed water and drainage water respectively. The feddan irrigated with fresh water consumed 2672 m3 compared with 2922, 2841 and 3263 m3 for groundwater, mixed water and drainage water respectively. The feddan of wheat irrigated with groundwater gave the high- est return of income changed costs that was 1.233 pounds. The farmers in the study sample used quantities of irrigation water greater than the amount that achieve efficiency in the case of irrigation with groundwater rate of 6.23%, while the farmers in the stud[1]y sample used quantities less than the amounts that achieve efficiency by 1.27%, 10.9%, 7.9% for wheat irrigated with fresh water, mixed water and drainage water, respectively. The research recommended using these different qualities of water in irrigation, but in the context of a set of parameters with not of focusing on the use of agricultural drainage water directly due to the Low productivity per feddan and the low average of water unit production and the share of water unit of the net return, certain attention should be paid to mixing drainage water with Nile water, and also to treating drainage water before mixing with fresh water of River Nile.

Two field experiments were conducted during the two successive seasons of 2011/2012 at the Experimental Farm, Kaha station, Qulubia Governorate to study the effect of using four levels of water regime ,i.e. 60%, 80%, 100 and 120% from class A pan evaporation and five safety materials, i.e. water (as control),amino-z, lithovit (a natural intensified CO2 foliar fertilizer ) as foliar spray on snap bean plants as well as the biofertilize mycorrhizal as a seed treatment before sowing and sap material as a absorbent polymer to increase with holding water capacity before sowing and the effect of that on growth, green snap bean yield Poulista cv ., physical and chemical characters as well as water use efficiency. The results indicated that, mycorrhizal seed treatment, lithovit foliar spray and soil treatment with sap material gave the highest values of green pod characters as well as the vegetative growth, in addition all the safety material used led to significant increment on pod yield and the favorable treatments were obtained by using sap material and foliar spray with amino -z. Concerning to using safety materials with water regime levels, it was found that, spraying snap bean plants with amino- z and irrigation with 120% levels from class A pan evaporation was the superior treatment on green pod yield followed by soil treatment with sap material with 60% of water level. Regarding to the mean of green pod weight, the results showed that treating seed with mycorrhizal and 120% level of water regime gave the highest values during the two seasons, then the treatment of foliar spray with lithovite with 80% level of water regime and the treatment by sap soil treatments with supplied by 60% of water irrigation. Concerning to water use efficiency, the data showed that supplied the plants with the highest amount of water 120% and 100% from water irrigation decreased the values of water use efficiency, on the contrary , it can obtained the highest values of water use efficiency from water supplied with 60% then 80% calculated by class A pan evaporation method. Regarding to the effect of safety material on water use efficiency, it was found that, sap treatment or foliar spray with amino-z then, mycorrhizal treatments gave the highest value of water use efficiency. Generally, it can recommend by using sap material of soil addition before sowing and foliar spray by amino- z followed by treating the seeds with mycorrhizal with irrigation level 60% or 80%to obtained the favorable green pod yield and the favorable water use efficiency.

This study was carried out to produce milk permeate beverage fortified with dried leaves of Moringa oleifera (DLMO) as innovative beverage. DLMO was added to permeate at concentrations of 0.5, 1 or 2%. Subsequently, the physiochemical, microbiological and organoleeptic properties of freshly innovative beverage and after 3, 7 and 10 days of storage at 5 ±25C were examined.  Addition of DLMO had significantly increased the total solids, protein, carbohydrate and ash contents of beverage. Acidity values increased gradually in all treatments during storage period. Bifidobacteria counts were higher in innovative beverages fortified with DLMO compared to control during storage period (10 days). Mould&yeast and coliform bacteria were not detected in innovative beverage when fresh and till the end of storage. Innovative beverage fortified with DLMO can be considered a good source of minerals (K, Ca, Mg and Fe) for human nutrition. The results indicated that innovative beverage fortified with DLMO contained higher essential and non essential amino acids compared to control. Organoleptic properties of innovative beverage fortified with DLMO were highly acceptable during storage period.

Sugar beet is an important crop that helps in establishing integrated agricultural-industrial societies, especially in the new reclaimed areas, it contributes in many industries such as sugar industry, and highly-value animal feed resulting from processing waste. Sahl El Tina had been chosen as it is one of the most important of the recent reclamation and aquaculture region depending on water of Al Salam Canal. To achieve the target of increasing Production of sugar beet it became necessary to increase the efficient use of economic resources ,and to achieve this objective study Data Envelopment Analysis (DEA) Approach had been used in order to estimate the technical and economic efficiencies allowing to reduce production costs and increase revenue, and thus support the expansion in the cultivation of the crop. The sample have 3 categories according to the area of the farm, the first category consists of 3 feddans or less, second category is more than 3 feddans and less than 7 feddans, the third category is more than 7 feddans to 10 feddans. The goal of the sample was to compare the efficiency of these categories, and recommended the optimum size of the farm.

The research estimated the efficiency of resource use among north western coast farmers in Marsa matrouh governorate using a sample of 200 respondents that were randomly selected; Interview schedules and structured questionnaires were administered to elicit information from the farmers. Data were analyzed using gross margin analysis, production, costs functions and resource use efficiency. The results for Tomato showed that, the regression analysis indicated that, R2 was highly significant at 1% level with the value of 90%. This implied that 90% of the total variations in Tomato  yield is explained by combine influence of all the explanatory variables (farm inputs) in the regression equation analysis, Gross margin analysis showed that farmers made profit (gross margin=  11810 LE / feddan). The resource use efficiency result showed that, the farm resources (cultivated area, organic manure, machines and labour) were under-utilized for Tomato production in the study area, The results for Cantaloupe showed that, The regression analysis indicated that,R2 was highly significant at 1% level with the value of 91%. This implied that 91% of the total variations in Cantaloupe yield is explained by combine influence of all the explanatory variables (farm inputs) in the regression equation analysis, Gross margin analysis showed that farmers made profit (gross margin = 15870 LE/feddan), the resource use efficiency result showed that two farm resources (cultivated area and labour )were under –utilized and one farm resource(N fertilizer) was over- utilized for Cantaloupe production in the study area.

The potato plants (Solanum tuberosum L.) vs. valor were exposed to different levels of nitrogen fertilizer (60, 100, 140, 180 kg N/feddan (4200 m2)) and in-row plant spacing (12.5, 25 and 50 cm) for maximizing the yield production to match food security needs under climate change impacts on Delta region,  Egypt. The experiment was carried out during two growing seasons (2010/2011 and 2011/2012) in split plot design at El-Bossily Farm, Agricultural Research Center, El-Behira Governorate, Egypt. The vegetative growth characteristics and yield parameters were measured. The result of this study verified that increasing nitrogen level up to 180 kg N/feddan significantly increased the vegetative growth, total and marketable yields than the other N treatments. The in-row plant spacing 50 cm was significantly increased vegetative growth and yield (kg/plant), but the total yield (kg/m2) had different trend. The highest total yield /m2 was obtained by 12.5 cm treatment. The interaction effect of 180 kg/feddan of N and 12.5cm in-row plant spacing were increased the total tuber yield (kg/m2) significantly. In contrary, the best marketable yield (tubers > 35 mm) /m2 was obtained by 25 and 50 cm in-row plants.  This study was concluded that the best agronomic practices for potato production obtained by application 180 kg N/feddan of with in-row plant spacing 25 cm treatment. The economical consideration of the different treatments showed that the best total net income was obtained by 180 kg/feddan N with 50 cm in-row plant spacing.

Resulted in the opening of the Egyptian society to the outside world, and the work of many Egyptians in  the Petroleum States to increase the level of their income on the one hand and increasing population growth rates of  Egypt on the other hand which is reflected to increase the amounts and rates of food commodities consumption in general, and Edible Oil and fats, in particular, where The per capita consumption of Edible Oil about 15 kg/year, which gives an indication of the increased size of the food gap of Edible Oil where the problem was in that Edible Oil become one of the most important sources of the increase in the cost of Egyptian agricultural imports as a result of the application of the GATT as the cost of the Edible Oil imports by about 47 % of the increase in the total value of Egyptian agricultural imports posing a heavy burden on the balance of payments, and then the research aimed to analyze the impact of different variables to determine the most important determinants of consumption of Edible Oil and fats.           To be included in the Egyptian agricultural policy to help the decision-maker to take the necessary corrective actions about it. Where the study found several factors affecting the consumption of Edible Oil and fats can be limited to the most important are as follows: The per capita consumption of Edible Oil (of Human unit).  The per capita expenditure on Edible Oil, the effect of the price / income  ratio of group of Edible Oil and fats, the frequency of frying in the same oil, the function of the head of household, the average price of a kilogram of vegetable ghee, the volume of containers of Edible Oil, Types of pot keeping the oil after use, the use of oil in a frying more than one type of food, rising per capita income (Human Unit), increase the rate of  per capita consumption (of Human unit), the proliferation of fast food shops, as well as shops , beans and falafel, increasing individual consumption of fast food, especially after the revolution due length of waiting of individuals in the Egyptian street . The study pointed out many of the expectations and proposals could limit the most important are as follows: Increasing the area of ​​land cultivated oily crops, need to focus on projects in Toshka and the Qattara Depression and the cultivation of parts of the northern coast, the return to agricultural rotation system of enter including the Oileeds, restart Edible Oil factories with full capacity both in the stages of refining of raw Oil imported or Edible Oil extraction from locally grown Oileeds, rationalizing the use of Edible Oil in domestic consumption.

The Fisheries is considered an important source of national income. Fish product is one of important component in the agricultural production. the problem of this study determined in increasing fish food gap with about 319 thousand tons in 2012. The study aimed to description and analysis of fish production in Egypt in terms of domestic production, imports, exports, consumption, the food gap, the proportion of self-sufficiency, the average per capita available amounts for consumption, In addition, studying the factors that effect on the production and consumption of fish in Egypt.   The study should be verification the following results   The fish production in Egypt is growing annually by about 55.9 thousand tons during the period average (1995-2012), which represents about 6.4% of the annual average, Imports of fish increase during the study period by about 4.5 tons by about 33.6 million pounds per year, and fish exports are increasing annually by about 0.68 tons by about 5.3 million pounds annually while the production of fish according to different sources show that fish farming ranked first by about 55.3% of the average amount of production, and the total northern lakes ranks second at about 14.7%, while the production of the Sea (White, Red ) ranked third by about 14.1%, and the River Nile is ranked fourth by about 10.2 and inland lakes and coastal ranked fifth and sixth by about 5.2%, 0.5% respectively during the study period . Nevertheless, the results show that there are statistically significant differences between the indicators during the period average (2008-2012). In addition, the results show that tilapia ranked first with an average production of about 646.4 thousand tons representing about 52.1%, While the average production of mullet, carp, catfish, reaches about 181.9, 142.1, 43.1 thousand tons respectively, representing about 14.7%, 11.5%, 3.5% respectively of the average total fish production during the period (2008-2012). The study also indicate that the most important economic factors that affecting on the fish production in Egypt is the amount of fish imports, the quantity of available fish, the partial elasticity of them are about -0.294 and 1.2, which indicates that an increase in the quantity of imports by about 1% leads to the decline of fish production by about 0.3%, increase the amount of fish consumption by about 1% lead to increase the amount of production by about 1.2%. However, the results show that the most important factors affecting on the amount of fish consumed in Egypt is the population and the average price of a kilogram of fish. Therefore, the study recommended the development of fisheries sector and set up of collection centers for the production of fish near fish farms, Moreover, the necessity of expansion in aquaculture to fill the fish food gap.
