The safe re-use of wastewater for agriculture is a desired goal in many arid zone countries. The potential of greywater as alternative irrigation source for vegetable crops was investigated. Tomato, pea and cantaloupe plants were drip irrigated with both fresh Nile water and greywater to access the impact on yield production and associated environmental and health risks. The biological properties of the two different sources of water clearly indicated that greywater was extremely higher in bacterial content compared with fresh Nile water. Pea plants showed significantly higher yield irrigated with fresh Nile water, however, tomato and cantaloupe plants gave significantly higher yield irrigated with greywater. Generally, the coliform populations in untreated greywater irrigated plants were higher than those irrigated with Nile water in all tested vegetables. The percentages of increasing in total coliform in untreated-irrigated greywater vegetables were 27.95%, 34.55% and 41.4% for pea, tomato and cantaloupe (averaged over outer and inner fruit tissues), respectively. Unexpectedly, central part of fruits for pea and tomato had highest coliform counts when compared to the outer surface using both Nile and untreated greywater. Overall, irrigation with greywater increased soil bacterial content by 15% while fresh Nile water increased it by 13% at the end of the experiment. In addition, greywater elevated the content of soil total coliform by 52% where fresh Nile water increased it by 30%. The results of this study indicated that untreated greywater should not consider as an alternative irrigation source for edible crops such as vegetables. In current investigation, the beneficial effects in tomato through giving significantly higher yield with greywater became worthless after the enormous fecal contamination that was detected in fruits. Several considerations must be adopted to minimize the health and environmental risks associated with greywater reuse in irrigation of vegetable crops.

The beneficial effects of boron, zinc and active dry yeast on yield and fruit quality of Zaghloul date palm grown at the Experimental Orchard, Faculty of Agriculture, Assiut University, Egypt was studied during 2011, 2012 and 2013 seasons. The experiment was set up in a complete randomized block design with ten replicates each of one bunch. All treatments were sprayed two times after fruit set and one month later. The obtained results could be summarized as follow: -       Boron, zinc and active dry yeast sprays significantly increased the fruit retention percentage and bunch weight compared to the untreated ones. Yeast application was more effective compared with boron or zinc application. -       Spraying either yeast, boron or zinc at any studied concentration was accompanied with improving fruit quality in terms of significant increase in fruit weight, total soluble solids and sugar contents. No significant differences were detected between spraying with yeast at 250 or 500 ppm, 500 or 1000 ppm zinc, as well as, boron at 1000 or 2000 ppm. Moreover, active dry yeast spraying revealed the highest improvement in palm yield and fruit quality. However, it can be concluded that spraying either boric acid, zinc sulphate or active dry yeast twice after fruit set and one month later increased the palm yield and improved the fruit quality of Zaghloul date palm. Meanwhile, using dry yeast as more effective than both boric acid and zinc sulphate.

The experiments were conducted at the farm of Al-Alamia located at Nubaria- Egypt, in plastic houses (6m x 45m) where solanaceous crops have been grown as monoculture, and aimed to evaluate the soil solarization in combination with benefit microorganisms for controlling the pepper soil borne pathogens and weeds under plastic-house condition. Supplementation of organic matter in plastic-houses resulted in noticeable increase in fungal, bacterial and nematode counts. However, the population densities of total fungi,Fusaria, total bacteria, spore former bacteria, actinomycetes and nematodes after 15 and 30 days in the solarized plastic-houses were drastically reduced as compared tonon solarized control soil. This reduction was gradually increased depended on the time of sampling (after 15 days of transparent polyethylene mulching or after 30 days). Soil solarization reduced sharply free nitrogen fixers, 30 days after treatment the elimination of the Azotobacter spp. and Azospirillum spp. from soil was recorded. However, the free nitrogen fixers were found to be recolonized after one month from transplanting the seedling pepper plants in non solarized and solarized soil, so artificial inoculation of pepper seedlings with strains of Azotobacter sp. and Azospirillum sp., were resulted great root colonization of plants than in non-solarized soil. Also, all annual weeds have been controlled with soil solarization which gave the best weed control treatment. On the other hand, solarization had pronounced effect on seedling establishment occurred in solarized plastic-houses. Increasing more than 30% in establishment of pepper seedling were recorded between the solarized and non-solarized plastic-houses which mulched with black sheets after three weeks of pepper transplanting.  The percentage of Phytophthora spp. isolated from the infected pepper seedlings were very high compared with other fungi, it was 49% of total isolated fungi after one week of transplanting. However, soil solarization increased pepper plant height and number of branches per plant as compared with non-solarized soil without black mulching or with black mulching. The pepper yield per plastic house up to 7 months increased with soil solarization by about 216 Kg, 18.3% over non solarized with black mulching, and 155 Kg, 12.4% over non solarized without mulching.

Pot trials were conducted under plastic house condition during two successive seasons of 2013/2014 and 2014/2015, at the experimental site of Central Laboratory for Agricultural Climate (CLAC), Agricultural Research Center, Giza, Egypt. The present study aims to determine the partial replacement of mineral nitrogen fertilization of tomato by nitrogen fixing bacteria with or without adding compost in sandy soil. Tomato seedlings (Lora F1Hybrid) were transplanted during the first week of October into plastic pots (30 cm diameter) filled with 10 kg of sandy soil. Three rates 25, 50 and 75% of the recommended mineral nitrogen in the nutrient solution for tomato with adding compostat 2% and nitrogen fixing bacteria (Azotobacter chroococcum and Azospirillium brasilense) at 20 ml/plant either individually or in combinationswere investigated on growth, mineral composition and yield of tomato plants compared to 100% of recommended nitrogen only (control). The plants were irrigated daily by drip irrigation and received 200 ml/plant of nutrient solution twice a weekly. The results showed that using 50 or 75% of N-mineral fertilizer + compost + nitrogen fixing bacteria gave the highest values of growth, mineral composition and yield of tomato. It is recommended that 50% of nitrogen mineral fertilizers for tomato plants could be replaced by nitrogen fixing bacteria in presence of compost, which in earn, reduce environment pollution caused by extensive application of mineral nitrogen fertilizers.

The problem of the search in the presence of large amount of waste is estimated at 74.7 million tons, including agricultural residues, which are estimated at about 23.9 million tons, representing about 32% of the total waste in Egypt without the benefit of full economic, which lead to the waste of economic resources, the study aims to attempt to shed light on the economic efficiency to Recycle agricultural residues to maximize economic benefit the study to the most important results: - Through the study of economic efficiency indicators to manufacture Tons of unconventional fodder of some agricultural residues indicate that the economic feasibility, where the average net revenue secondary outputs crops referred to was about 85,38 pounds (tons and net revenue crop residues of maize production reached a maximum of about 147,5pounds (tons, followed by net revenue remnants of rice crop, cotton, sugar beet, municipal beans about 77.6, 72.2, 69, is 60.6 pounds per ton, respectively. The average profitability of the pound investor secondary outputs of crops referred to was about 0.29 pounds. - The manufacture of organic manure (compost) of agricultural residues of economic feasibility, where the average net revenues of outputs secondary crops referred to hit about standing at 118.6 pounds (tons and net return on remnants of rice crop reached a maximum of about 141 pounds (tons, followed by net revenue crop residues of rice, maize, beans, municipal cotton, sugar beet, about 77.6, 72.2, 69, is 60.6 pounds per ton, respectively. - To examine economic efficiency indicators to rotate tons organic fertilizers from animal waste indicate that the economic feasibility, where it was found that net revenues recycling reached about 154.8 pounds (tons). The study recommended that: - The possibility of making use of agricultural residues and treated to produce organic fertilizers, as a substitute for traditional fodder caravan of chemical fertilizers, and fodder expensive traditional crops estimate net revenue recommends rotating the sample conversion of remnants of corn, rice, cotton to feed non-traditional and rotate remnants of rice, maize, beans to municipal organic fertilizer, where they win economically. - Attention to economic development programs for the recycling of waste and encourage recycling of agricultural waste industry. - Wider dissemination of waste recycling technology through awareness in charge of this process, the economic importance of re-use of these residues.

The recent study aims to: identify a vision of agricultural extension work to reduce the degradation of agricultural soils, and determine the relationship between the independent variables studied, and the degree of vision of agricultural extension work to reduce the degradation of agricultural soils and identifying the farmer's suggestion to reduce Soil degradation. The study was conducted in Siwa Oasis in Matrouh Governorate. Data were collected through the personal interview with a systematic random sample of 148 farmers in Siwa Oasis using a questionnaire.

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.

Effect of using different concentration of acetic acid (5, 7.5, 10 and 12.5%) on microbiological quality, pH, lipid oxidation and sensory properties of beef shawarma during storage at 4°C for 16 days were examined in this study. The results  showed   that addition of acetic acid at 10% concentration reduced and retard the growth of total number of  microorganisms by one log cycle, prevented  the growth of  Enterobacteriaceae, Coliform, E. coli , Psychrotrophic bacteria, and Staphylococcus aureus . in beef Shawarma   during storage at 4°C for 16 days. Both pH (6.1 to 6.14) and TBA (0.056-0.97  malonaldhyde absorbance /kg oil) did not much affected with increasing the concentration of acetic acid added to beef Shawarma. Meanwhile the increasing of acetic acid concentration caused a noticeable reduction in redness, slight changes in wave length, purity, visual density and brightness of beef Shawarma colour. Panelists showed that the dark grayish colour, sourish aroma, sourness taste, toughness texture of cooked beef Shawarma increased with increasing acetic acid concentration added to this product. Storage at 4°C for 16 days caused slight changes in the above measured properties.

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.

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.
