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.

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.

The present study was carried out during two successive seasons, 2011/2012 and 2012/2013, at the Agricultural Research Station; El-Otouria, Sheehaniya, Doha, Qatar; to investigate the response of two tomato cultivars (Isabella and Milas) to biofertilizers and amino acids. Two biofertilizer treatments, rizobacterien at a rate of 2 and 4 liter per feddan and one of amino acid (Delfan) at a rate of 200 ppm, were used. Chicken manure, at a rate of 10 tons/ feddan, was the control treatment. Results showed the superiority of Isabella compared to Milas in terms of vegetative growth and fruit yield. Using Rizobacterien at a rate of 4 liter/feddan plus Delfan (amino acids) at a rate of 200 ppm increased growth and fruit chemical characters, earliness and total yield. The average fruit weight per plant was significantly high under Rizobacteria at a rate of 4 liter/feddan plus Delfan (amino acids) at a rate of 200 ppm. The lowest vegetative growth, fruit and yield characters were obtained from Rizobacteria at a rate of 2 liter/feddan. The water productivity results showed that all treatments led to the increase of fruit yield. Isabella cultivar had higher water productivity than Milas cultivar. Using of Rizobacterien at a rate of four liter/feddan also increased the water productivity. The same trend was obtained by using Delfan at a rate of 200 ppm. Concerning water productivity, Isabella cultivar had higher water productivity 16.7 and 17.2 kg of tomato fruits per cubic meter of irrigation water (m3) compared with Milas cultivar which produced15.9 and 16.5 kg tomato fruits per cubic meter of irrigation water for first and second seasons, respectively. Isabella cultivar plus amino acid (Delfan) gave the highest water productivity 19.1 and 19.7 kg of tomato fruits per m3 water for first and second seasons, respectively compared the other treatments.

The need to increase the organic soil matter for sustainable production to match food security under semi-arid Egyptian conditions (high temperature, low preception, shortage of organic fertilizer etc..) led to looking for new sources of oragnic materials such as modern composting technologies and increase the effeiency of recycling. The field experiment was carried out during the two winter successive seasons of 2011 and 2012 under open field conditions in protected cultivation site, Central Laboratory for Agriculture Climate (CLAC), Agriculture Research Centre, Giza, Egypt. Peas (Pisum sativum), cv. Lincolin was used in this study. The study aimed to investigate the use of vermicompost as alternative organic fertilizer by different rates (15, 20 and 25 m3/feddan) compared to cattle manure (20 m3/feddan as a control) combained with two plant distances (30 and 50 cm) which performed in split plot design. The obtained results indicate that increasing the rate of vermicompost from 15 to 25 m3/feddan led to increase the values of physical and chemical properties of both pea plants and yield characteristics. The highest vegetative growth characteristics were recorded by application rate of 25 m3/feddan combined with 50 cm plant distance followed by 20 m3/feddan combined with 30 cm compared to the other treatments. The application rate of vermicompost 25 m3/feddan combined with plant distance 30 cm gave the highest yield of peas per feddan. Concerning, the highest fruit quality parameters were estimated under application rate of vermicompost 20 m3/feddan combined with 50 cm. The recommended treatment under this study conditions was the use of vermicompost 25 m3/feddan combined with 30 cm followed by 20 m3/feddan combined with 30 cm of plant distance. The vermicomposting of organic wastes and applied it to the soil as an organic fertilizer instead of burial or inceneration led to store CO2 in the soil and decrease its emission.

The response of “Canino” apricot trees to different soils were studied in three different regions, in El-Menoufia Governorate (as a sand and clay soil) & Alexandria Governorate (as a calcareous soil) during the two successive seasons of 2010 & 2011. Evaluation included vegetative growth, flowering, fruit set, tree productivity and fruit characteristics. Chilling units as well as growing –degree hours were also estimated through the two studied seasons. Results indicated that the vegetative growth was the best in clay soil for shoot length, leaf area and leaf chlorophyll content. Concerning periods of flowering, fruit set and harvesting dates there were variations among the three types of soils. Sand soil was the earliest followed by clay and calcareous soils. Percentages of nitrogen, phosphorus and potassium were positively affected by soil type. Also, Fe, Mn and Zn were affected by soil type. “Canino” apricot trees produced earlier fruit yield with the better fruit quality in sandy soil, whereas clay soil type gave the greatest yield followed by sand and calcareous soils.

Two field experiments were carried out in Agric. Expt. Farm at Shalakan, Kaleobia Governorate, Cairo, Egypt during 2010/2011 and 2011/2012 growing seasons to study the response of some bread wheat cultivars to sowing dates. Each experiment included 15 treatments which were the combination between three wheat cultivars (Giza 168, Sakha 93 and Gemmiza 9) and five sowing dates (1st October, 16th October, 1st November, 16th November and 1st December). The experimental design used was split plot design in 6 replications. The data revealed that sowing dates and cultivars both significantly affected wheat yield and its components. Sowing on 1st November exhibited significant maximum plant height, number of spike/m2, main spike length and weight, grains number of main spike as well as grain, straw and biological yields as compared to early or late sowing in the season. Concerning wheat cultivars, Gemmiza 9 gave significantly highest yield and its components in comparison to Sakha 93 and Giza 168. The effect of the interaction between wheat cultivars and sowing dates were significantly differed in plant height, main spike length and weight, grain weight/spike as well as grain, straw and biological yields as well as GCPY. Gemmiza 9 exhibited the significant highest parameters when sown on 1st November as compared to the other studied two cultivars. The data revealed that sowing Gemmiza 9 wheat cultivar on 1st November was the most suitable environmental conditions for growing wheat in Kaluobia Governorate.

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.

Cent. Lab. for Design and Statistical Analysis Research, ARC. Agric. Research Center, Giza, Egypt
Sharkia Governorate characterized by environmental and agricultural characters suitable for the production of sugar beet crop that making it one of the most important production areas in Egypt. Despite the importance of sugar beet crop as an economic crop for production of sugar, it has not taken enough attention to address the technology gap prevailing between researchers and producers in the employment of agricultural productivity resources to achieve the economic efficiency and that reduces faddan productivity and its return. This requires evaluating package of current agricultural practices affecting the productivity of the crop. So, the study used some economic criteria and statistical methods that achieve the objectives of the study and enhance the results such as correlation and regression procedures, change partitioning method and crop budget. The study was based on a field random sample of thirty farms in the province of Awlad Saker .. The study showed that the most important quantitative variables affecting the average production per faddan of sugar beet are the amount of nitrogen fertilizer, phosphate fertilizer amount, seed amount, the amount of irrigation water where the combination of these factors contribute about 84% of the total quantitative factors affecting crop production. Also, the most important qualitative productive variables affecting the average productivity of the crop are number of hoeing times, the distance between hills and planning rate where these factors contribute about 64% of the total qualitative factors affecting the productivity of that crop. Then the most important quantitative and qualitative factors affecting average production per faddan of sugar beet are the amount of nitrogen fertilizer, phosphate fertilizer amount, amount of irrigation water, the distance between hills, number of thinning times, where these factors contribute by 83% of the total factors affecting the sugar beet crop production. The study shows lack of commitment by producers of sugar beet recommendations of the Ministry of Agriculture with respect to quantitative and qualitative technology practices where the amount of the technological gap between the recommendations of researchers and practices of farmers for the row width about 4.32 tons/ faddan, number of times of thining 6.8 tons/ faddan, number of times of hoeing 6.63 tons/ faddan, number of times irrigation 3.26 tons/ faddan, the distance between hills 5.5 tons/ faddan, planning rate of 1.5 tons/ faddan for farmer experience, 2.5 tons/ faddan, number of times of replanting 0.57 tons/ faddan. The total monetary value of these gaps is around 1501.65 pounds, 2414 pounds2353.65 pounds, 1157.3 pounds, 1952.5 pounds, 532.5 pounds, 887.5 pounds, 202.35 pounds, respectively. Therefore, the study recommends using the technological recommendations package of agricultural practices according to the research recommendations, with a focus on the most important factors affecting the productivity of the sugar beet crop, to reduce the gap between research recommendations and farmers' practices.

The study aimed at studying economic effects of global energy and food on the most important Egyptian imports. Descriptive and analytical statistical methods were used to achieve study objectives. Mathematical averages percentages and annual growth rates of variables under study were estimated. Expected values of imported food commodities using double exponential smoothing method was used. The study reached to some important conclusions, namely Global price and production of oil, coal, natural gas, ethanol and biodiesel have risen during the period 1996-2011. There were also a significant relationship between world prices and production of the above products. The price elasticities were about 0.089, 0.32, 0.174, 0.062, and 2.5 for these products respectively. The increase of oil price has an impact on food imports showing an increase of about 3.46% as a result of 10%of oil price increase. The study revealed that world oil price will be about $133.2/ a barrel in the year 2015 compared with $112.9/ barrel in the year 2011. It is therefore expected that value of food imports will increase to about $ 12.9 billion in the year 2015 compared to $ 10.6 billion in 2011.
