Efficiency of Certain Evaluated Pesticides and Phytochemicals on the Inspected Aphids (A. gossypii) on Growing Cucumber Plants in Greenhouse and Market
The present research was carried out during winter and spring growing seasons of 2014 for controlling the aphid attacking the cultivated cucumber in greenhouse. In the spring season of 2014, azadirachtin was evaluated against the aphid and compare with the tested essential oils, while in the winter season azadirachtin was compared with two insecticides (abamectin and pyrethrin). Metalaxyl as a fungicide was applied during the both growing seasons as a protective agent against the downy mildew. The results showed that onion oil and red basil oil were the most effective treatments throughout the test period of spring season in reducing the number of aphid giving the highest general mean of reduction percentages, 73.8%, 68.85%, respectively, but in winter season, azadirachtin and abamectin were the most effective treatment throughout the test period in reducing the number of aphid giving the same highest general mean of residual reduction percentage (74.17% and 74.15%), respectively, while Pyrethrin showed a reduction of 72.40%. The residues of the applied pesticides, were determined in the collected samples of commercial and experimental cucumber fruits. The results showed that the detected amount of carbohydrates; potassium and vitamin C were high in the sample of experimental cucumber fruits (prince variety), where the lower detected ones were recorded in commercial cucumber fruits (mixed varieties). Moreover, it was found that commercial cucumber fruits contained higher amount of the pesticide residues of propamocarb (a carbamate fungicide) (0.53 ppm) and iprodione (a carbamate fungicide) (0.19 ppm) which are greatly dangerous to human health. It is noticed that the Egyptian farmers are using so much pesticides and therefore, it is important to advise the farmers about the type of pesticides and the rate they are applying via safe recommendations.

Morphological Markers for Early Selection in Strawberry Breeding Programs
This study was conducted in El Tahrir South Station, Ali Mubarak Farm, Horticulture Research Institute, Agriculture Research Center.,Cairo, Egypt at the winter seasons of 2012, 2013 and 2014. The main aim was to decide upon a morphological character in the juvenile stage of strawberry to be considered as a morphological marker; i.e., Breeding Program Selectable Marker (BPSM) - for expecting the production level in the breeding programs, instead of waiting for the whole growing season; to save time, money, land and labor efforts. Thirty eight characters were evaluated using eleven strawberry cultivars, to assess the important morphological differences among them. Results showed that there were some initial vegetative growth characters at the early stages of development in the nursery during the propagation of seedlings that might be relayed upon to determine the expected yield at an early stage, without delaying to the end of whole growing season. There were some clear and significant differences among all cultivars in most of the studied traits, which might make selection effective for such complicated character of total yield. Correlation results showed significant and desirable positive correlations between total yield and each nine of the morphological traits; i.e., leaf color of the upper side (0.35**), terminal leaflet length in relation to width (0.34**), number of stolons (0.04**), flower earliness (0.19*), corolla number (0.18*), flower position in relation to foliage (0.30**), flower diameter (0.24**), calyx size in relation to corolla (0.53**) and petals arrangements (0.29**). On the other hand, some significant negative correlations were detected between total yield and each of other nine traits. Significant differences and correlation among these traits suggests that, they could be taken into account when selecting for productivity improvement in strawberry breeding programs.

Inheritance of Powdery Mildew Resistance and Some Economic Traits in Cucumber (Cucumis sativas L.)
The present study was carried out during successive growing seasons for the years 2014 and 2015, under greenhouse conditions, at Sabahia Horticulture Research Station, Alexandria Governorate, Egypt. Six inbred lines of cucumber were utilized in a half-diallel cross breeding program to obtain 15 F1 hybrids. The breeding program was concerned with powdery mildew resistance, economic characters and their attributes; i.e. total fruit yield/ plant, number of fruits/plant and average fruit weight; in addition to the fruit quality characteristics; i.e., fruit length and fruit diameter. Results showed that the hybrid P2×P4 gave a very high resistance (100%), which is considered an immune (I) hybrid, while, the genotypes P2, P1×P2, P1×P3, P2×P5 gave high powdery mildew resistance (HR); i.e., (98.33%, 98.23%, 96.3% and 95.83%), respectively. The additive gene action exhibited highly significant, positive or negative, values in all the tested crosses for total yield/plant; whereas, the dominance effect values were found to be positively high significant in most crosses. The additive gene action exhibited positive significant values for powdery mildew resistance in most crosses; except the cross P1×P2, which gave a negative high significant values and the two crosses P1×P5 and P2×P3, which gave insignificant values. The dominance gene action was found to have positive high significant values in most crosses for this character.

Esterase Isozyeme as an Indicator for the Genetic Variations of Bactrocera zonata (Saunders)
The peach fruit fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae), is a serious pest in the last decade attacking a wide range of fruits in Egypt. The esterase isozyme patterns during the three different stages (larvae, pupae and adults (males and females) of three wild populations (Alexandria, El-Fayoum and Siwa) and laboratory strain were observed in agar-starchpolyvinylpyrolidine (P.V.P) gel. Two esterase isozyme (Est.a1and Est.a2) in anodal and three bands in cathodal (Est.c1, Est.c2 and Est.c3) for all stages were found. The esterase activity of female was more than that of male in the three tested wild populations and laboratory strain. The population of Siwa had greater esterase activity than those of El-Fayume and Alexandria. Generally, the wild populations were found to have more esterase activity than the laboratory strain.

Effects of Dimilin on Young Spodoptera littoralis (Boisd.) Larvae
Experiments were conducted under laboratory conditions to determine the susceptibility of the first three larval instars of Spodoptera littoralis (Boisd.) to the antimoulting agent”dimilin”. Obtained results indicated that the response of 1st, 2nd,and 3rd,instar larvae of S.littoralis were abnormal, because the low concentration of 12.5 ppm or 25 ppm proved sometimes either more effective than, or equally effective against S.littoralis as the higher concentration (e.g.50ppm), This result might be attributed to the mode of action of the subject synthesis inhibitor under investigation or to the amount of contaminated diet consumed by each of the tested larval instars. Moreover, this compound might exhibit phagostimulant or deterrent effects against young larval instars. Also, the contact activity of the compound might contribute to the fact that the1st, instar larvae with relatively more exposed surfaces succumbed to death in periods (LT50=43-60 hrs) shorter than those needed for the 2nd, (LT50= 68-72 hrs)or the 3rd, (LT50 =51 60 hrs) instar larvae. To investigate the effect of the exposure period to dimilin on the larval mortality rates, three groups of each of the first and the second instar larvae of S.littoralis were allowed to feed on castor bean -oil leaves that were dipped in certain concentration of dimilin. Feeding on contaminated leaves proceeded for different exposure periods of 24,48,72 hrs, after which the larvae were offered untreated leaves and mortality data were recorded. The lowest concentration of 12.5 ppm was more potent than the other tested concentrations. However statistical analysis of the data showed that the higher concentration accelerated mortality as the LT50 values were 60, 47& 43 hrs for 50,25&1 2.5 ppm treatments respectively. On the other hand, continuous exposure period for 72 hrs, to the high concentration of treatments being 25 &50 ppm accelerated death and the LT50 values were 75 & 72 hrs, respectively. In fact,while the LT50value for 12.5 ppm was 68 hrs.

Growth Responses of Calendula (Calendula officinalis L.) to Temperature Regimes and Different Soil Types
Temperature stress is the major environmental regime that affects agricultural production worldwide, especially in arid and semi-arid regions. Arid and semi-arid regions are characterized by highly variable environmental conditions were temperature goes extremely low to extremely high and affects the performance, physiology and biochemistry of the plants. This research investigated the effect of temperature regimes on sowing seeds of Calendula officinalis L. at (1, 15 September and 1, 15 October, 2013 and 2014) grown in different soil types (clay, loamy, sand and mix between them). Significant increases in vegetative growth characters were observed for plants cultivated in sandy soil compared to those cultivated in clay loamy or mixed soils. The best result was obtained with 15 September treatment sandy soil plants. This result included higher branches number and leaf area, higher shoot fresh and dry weights, as well as higher number of flowers. Physiological traits include transpiration rates, stomatal conductance, intercellular CO2 concentration and sample cell H2O, were highly significant in first October planting date with clay loamy soil type in both seasons. Environmental regimes and different soil type’s showed clear effects on the biochemical contents (total soluble protein, H2O2 and catalase activity fractions of the leaves) of three week old seedlings. It is concluded that sowing in September in sandy soil is recommended for Calendula production in arid and semi-arid regions.

Availability and Uptake of Cadmium, Copper, and Zinc by Radish Plant Grown on Contaminated Soils as Affected by Compost Amendment
The study was conducted to elucidate the effect of three levels of compost amended soils (0, 3, and 6%, w/w) on Cd, Cu, and Zn extractability and uptake by radish plant (Raphanus sativus) grown in calcareous and sandy soils contaminated with 0, 40, 80 or 160 mg metal kg-1 soil. DTPA extraction and greenhouse experiments were designed. The study revealed that the addition of compost treatments improved the plant biomass in both uncontaminated/contaminated two soils since the dry weight of shoots and roots for the two compost treatments was higher than that of the control (0 compost addition) even in high contamination level. Also, For Cu and Zn, the plants cultivated in metals levels (40-160 mg kg-1) showed a significant increase in the dry weight in both radish shoots and roots grown in the both soils; whereas increase Cd levels from 40 to 160 mg kg-1 decreased the dry weight of both radish shoots and roots. DTPA extractable Cd and Cu in addition to their concentrations in radish shoots/roots grown in the soils were decreased as a result of compost amendments with more pronounced at high compost level; whereas the opposite results were obtained for Zn. Good correlations were obtained in most cases between DTPA extractable metals and absorbed by radish plant indicated by correlation coefficients. These findings highlight the applicable of compost to ameliorate Cd and Cu risks in high contaminated soils.

Salicylic Acid Efficacy on Resistance of Garlic Plants (Allium sativum, L.) to Water Salinity Stress on Growth, Yield and its Quality
This experiment was conducted and replicated during both winter seasons of 2013/2014 and 2014/2015, respectively at Soil Salinity Laboratory, Alexandria. This research was conducted to study the effects of water salinity and the application of salicylic acid (SA) on garlic growth performance, yield and its quality. Four levels of saline irrigation water treatments were used; i.e., 435 (fresh tap water as a control), 1500, 3000 and 4500 ppm. Three levels of salicylic acid treatments were foliar applied on garlic plants at the rates of 0, 150 and 300 ppm. The spraying was applied biweekly. The results indicated that the vegetative characters, yield and yield quality were; negatively, affected with increasing saline water levels from 435 up to 4500 ppm. Spraying SA on the leaves garlic plants led to decrease the negatively effects of the saline water on the tested characters. The best results were given when salicylic acid was sprayed at the concentration of 300 pm. The interaction between saline water salinity and SA concentrations did not show any significant effects on all the studied garlic characters. Also, data appeared that spraying garlic plants with SA at the concentration of 300 ppm exhibited the highest values for bulb fresh weight (g/plant), average clove weight (g), no. of cloves per bulb, bulb diameter (cm) and nick bulb diameter (cm) with any of the tested saline water levels. Spraying garlic plants with SA resulted in relatively increasing potassium concentration in comparison to sodium content and this result might be indicated that SA application improved the performance of garlic plant to the stress of irrigation with saline water. The recommendation of this research; based on the obtained results under the conditions of this study, is spraying garlic plants with SA at the concentration of 300 ppm biweekly when having to irrigate with saline water to reduce the adverse effect of saline water on the economic characteristics of the garlic crop.

Performance of Some Faba Bean (Vicia faba L.) Cultivars Sown at Different Dates
The present investigation was conducted in the winter seasons of 2013/2014 and 2014/2015 at the Agricultural Research Station, Faculty of Agriculture, Alexandria University, Abis, Egypt, to study the effect of three sowing dates (Oct. 20th Nov. 10th and Dec. 1st) on the performance of eleven faba bean cultivars in a randomized complete block design, with three replications, in a split-plot arrangement. The investigation aimed to determine the best combination between genotypical and environmental factors for high yield, and evaluate seed yield and its related characters in faba bean (Vicia faba L.), cultivars sown at different dates. The results showed that most of the studied yield and quality characters were significantly influenced both by sowing date cultivars and their interaction. The present investigation emphasized the importance of sowing at the appropriate sowing date to fulfill the potential yield of faba bean cultivars. The best sowing date was October 20th which gave the highest productivity for all studied faba bean genotypes, especially Misr 1, RenaMora, Nubariah 3, Sakha 3 and Giza 843. The study, also, indicated the possibility of delaying sowing to November 10th, but, a reduction in seed yield would be expected that would vary, according to cultivar.

Initial Growth Response and Chemical Composition of Moringa oleifera Seedlings to Different Levels of NPK and Biofertilizer at Two Different Soil Types
The present work was carried out in the experimental greenhouse at Antoniadis Research Branch, Horticultural Research Institute, Minestry of Agriculture, Alexandria, Egypt, during two successive growing seasons, 2013, 2014 from first of March to end of November for each season to study initial growth response and chemical composition of Moringa oleifera seedlings to different levels of NPK, biofertilizer and two different types of soil. M. oleifera seeds were sawn cultivated in polyethylene bags (3 kg capacity) filled with two soil types; sandy loam and a mixture of peatmoss: sand (1:1 w/w). The resultant seedlings were treated with mineral fertilizer and biofertilizers inoculums. Plants were harvested after 9 months of cultivation. The height of seedlings (cm), total fresh and dry weight, (g) and mineral contents (N, P, Ca, Mg, K, and Fe) were recorded. Protein content, carbohydrates, total antioxidant activity and total phenols were also determined. Best results in all parameters were obtained with sandy loam soil at mix level of NPK and biofertilizers (1 g N + 1⁄2 g P +1⁄ 2 g K +1 ⁄ 2 g HALEX) ⁄kg soil. Seedlings height recorded 154.50 and 174.75 cm in the first and second seasons, respectively, however, total fresh weight was 77.68 and 90.03 g; total dry weight was 41.35 and 43.55 g, at the same order was found for the mineral content of the leaves, (5.42, 1.63, 1.93, 5.61, 1.42 % and 310 ppm for N, P, K, Ca, Mg and Fe, respectively) in the first season. Also, leaves of M. oleifera seedlings gave high content of protein, carbohydrates, total antioxidant activity % and total phenols (mg GAE/g extract) with sandy loam soil and mix of mineral and biofertilizers at the same rate. Since it was 23.28, 18.28, 56.24, % and 125.1 mg GAE/g extract, for protein, carbohydrates, total antioxidants activity and total phenols, respectively.

Effect on Organoleptic Properties of Biscuits Fortified with Fenugreek Seed Germinated Until 5 Days
The objective of this study was to evaluate the effect of fortification of biscuits with 10%, 20% and 30% of fenugreek seed that germinated for 2, 3, 4, and 5 days. The Organoleptic properties results showed that a maximum of 10% germinated fenugreek flour (GF) for 2 and 3 days can be incorporated to prepare acceptable quality biscuits. But 10 and 20% germinated fenugreek flour is preferred when increasing germination time for 4 and 5 days. Increased in the germination time and percent of adding germinated fenugreek flour to wheat flour altered the contents of protein and dietary fiber. These biscuits can be safely stored in polypropylene bags up to 2 month without altering their organoleptic properties.

Fate of Nitrate In Soil Cultivated With Maize (Zea mays L.) Under Different Patterns of Irrigation Regime and Localized Compaction
The objective of this study was to evaluate the localized compaction (LC) and irrigation regime application management on maize (Zea mays L.) growth grown in calcareous soil and nitrate leaching from a maize field and also to evaluate LEACHM model for predicting water, and nitrate spatial and temporally in the soil. Field experiment was carried out using calcareous sandy loam soil in ELBoston region, West Nile Delta, Egypt, under furrow irrigation system. Two water irrigation regimes were used: Field capacity (I-1) and Saturation (I-2) as upper limits for soil water contents. The lower limit for irrigation for both regimes is 50% of soil available water. Ammonium nitrate fertilizer was banded with four treatments of localized compaction: control without compaction (LC-1), compaction under a fertilizer band (LC-2), compaction above a fertilizer band (LC-3) and a combination of the previous two positions (LC-4). The four compaction techniques did not affect significantly the soil nitrate concentrations under F.C. irrigation treatment (I1). There were significant differences between the two irrigation regimes (I-2 and I-1) in grain yield, ear weight, ear tall, ear diameter, leaf surface area, plant height, stem diameter, leaf fresh and dry weight, plant biomass production, total dry matter and nitrate leaching losses. These differences may be due excessive NO-3 leaching in I2 irrigation treatment. Leaching losses of NO-3 of I-1 irrigation treatment decreased by 75.68% with comparison to I-2 irrigation treatment. The average leaching losses for localized compaction treatments under I-1 irrigation were 36.43, 38.10, 31.22 and 31.86 kg ha-1, respectively, and the corresponding losses for I-2 irrigation were 177.76, 179.85, 104.31 and 103.93 kg ha-1 for LC-1, LC-2, LC-3, and LC-4, respectively. The LEACHM model well predicted the concentrations of NO-3 in soil profile and leachate as compared with the observed values. The ability of the model for NO-3 prediction was evaluated using different statically scales which proved that LEACHM model is a useful tool for optimizing and managing the application of irrigation water and N fertilizer in maize field under the used experimental conditions.

Latent Effect of Two Formulated Botanical Fine Dusts on Agrotis ipsilon (Hufn.) Generation
The present study was conducted to evaluate the biological performance of two botanical fine dusts of ploughman's and mexican tea grasses. It was found that the comparative calculated high means numbers of alive larvae in the untreated check (9.33±0.33) was significantly more or less decreased due to the performance of prepared baits of ploughman's fine dust at concentration rates of 1.0 up to 3.0 gm, and distinctly ended by the death of incipient adult-moths of the insect-pest. Versus, the revealed delayed effect of its higher concentration rate of 4.0 gm in the prepared bait, which gave the least detected values of mortality and malformed pupae (2.94 and 2.94%, respectively), which revealed its adverse biophysiological effects on the development of (f1) generation, followed by complete failure of (f2) 2nd one. Remarkably, all of the tested concentration rates of mexican tea grass fine dust alone (at 0.5, 1.0 & 2.0 gm) or / and admixed with the fine dust of ploughman's grass at rates of 1:1 or / and 1:2 gm caused rapid and complete failure of development of parent generation after larval treatment. Therefore, the extracted fine dusts for both evaluated natural plants (Mexican tea and ploughman's grasses) could be considered potential alternative to the use of conventional insecticides in the bait, as natural means in A. ipsilon control.

Effect of Plant Density and intercropping Pattern on yield and Competitive Relationships of Maize and Cowpea
Two field experiments were carried out at Research Farm of Alkod Station (Delta of Abyan) in 2012/2013 and 2013/2014 seasons to study the effect of plant density and intercropping pattern as well as their interaction on yield and competitive relationships of maize and cowpea. Four plant densities were used (56000, 67000, 83000 and 111000 plants /hectare) and three intercropping patterns (1:1, 2:1 and 3:3) for maize and cowpea respectively, in addition to sole cropping treatment. The results could be summarized as follows: - Increasing plant density significantly increased biological and grain yield of maize while harvest index was decreased. Intercropping patterns significantly reduced biological and grain yield of maize while harvest index was increased. Interaction between plant densities and intercropping patterns significantly affected biological and grain yield of maize as well as harvest index and the maximum grain yield was obtained under 2:1 intercropping pattern at 83000 plants/ hectare. - Biological and seed yield of cowpea were significantly increased by increasing plant density while harvest index was decreased with significant value in the second season. Intercropping patterns significantly reduced biological and seed yield while harvest index was increased. The interaction between plant densities and intercropping patterns had significant effect on biological and seed yield of cowpea in both seasons as well as harvest index in the second season and the highest seed yield was obtained under 3:3 patterns at 111000 plants/ hectare. Land equivalent ratio( LER) and relative crowding coefficient( K) values indicated that intercropping cowpea with maize gave yield advantage at all combinations of plant densities and intercropping patterns and the highest values of LER (1.51 and 160) in the first and second seasons respectively were obtained under 3:3 pattern at 111000 plants/ hectare. - Aggressivity values and competitive ratio indicated that maize was the dominant intercrop while cowpea was the dominated intercrop.

Effects of the Organic Fertilizers and Modified Evaporative Cooling System on the Productivity of Tomatoes Greenhouse in Hot and Humid Regions
In hot and humid climates such as the tropics, coastal areas of the subtropics and Mediterranean basin, crop growth in greenhouses during hot and humid summer is almost impossible because of the high temperatures occurred inside cause plant stress and death. The aim of this experimental work was to investigate the effects of a developed evaporative cooling system and using different rates of dried biogas digester residues as organic fertilizer on the growth, productivity, and fruit quality of tomato crop. Two similar gable-even-span greenhouses were utilized at EL-Sabahia Horticultural Research Station, Alexandria, to grow and produce tomato crop during the summer seasons of 2014 and 2015. Each greenhouse was equipped with a complete evaporative cooling system. One of them was modified (MECS) by utilizing a solid desiccant. The other one used fan-pad system, (FPECS). The obtained data revealed that the average indoor temperatures, relative humidity and vapor pressure deficit of the MECS greenhouse were lower than the FPECS greenhouse. At noon, the maximum greenhouse temperatures decreased below the outside temperature by 2.2 oC for MECS while, it increased by 1.6 oC for FPECS. The maximum indoor temperatures were 42.2, 28.8 and 31.7 oC for un-cooled, MECS, and FPECS greenhouses, respectively. The greenhouse temperatures decreased at noon below the outside temperature for MECS 3.2 and 1.3 oC while, it increased by 1.6 and 1.6 oC for FPECS, for the emissive and highly solar radiation days, respectively. Organic fertilizers, (dried biogas digester residue at 30, 20, and 10 m3/fed and farm yard manure at 20 m3/fed) were applied to investigate their effects on growth, yield and quality as well as chemical constituents of tomato plants. Results of this work showed that the application of 30 m3/fed of dried biogas digester residue significantly increased the vegetative growth, yield and fruit quality of tomato crop. Meanwhile, there were no significant differences between the application of 30 and 20 m3/fed applications in most studied characters. The results showed also, that farm yard manure application at rate of 20 m3/fed surpassed the 10 m3/fed application of dried biogas digester residue with no significant differences. The increase percentages in early yield, number of fruit per plant, fruit weight, total yield per plant and total yield per feddan were 21.28, 14.28, 14.60, 7.56, 23.03 and 23.03%, respectively for 30 m3/fed dried biogas residue over farm yard manure, (20 m3/fed) while, they were 18.91, 13.57, 6.40, 20.65 and 20.65% in 2014 and 2015 seasons, respectively. It can be concluded that application of 30 m3/fed dried biogas residues was the best treatment to produce the highest vegetative growth, yield and quality of tomato plants.

Effects of Water Treatment Residuals on the Kinetics of Ni(II) Sorption and Desorption in Some Arid Soils
The mobility and bioavailability of nickel (Ni) is strongly dependent on the mechanisms associated with Ni sorption and desorption kinetics in soils. In this contribution, the effects of drinking water treatment residuals (DWTR) applications, as a low-cost adsorbent, on characteristics of Ni sorption /desorption kinetics in three arid soils having different properties were studied by batch experiments. Batch sorption kinetic experiments revealed that Ni sorption behavior involves fast and slow sorption reactions. The fast reaction accounted for> 70% of the total sorption within15 min (the first sampling time). Desorption experiments revealed that Ni desorption was hysteretic in nature, which indicated a irreversible process. The time-sorption and desorption data generated for the DWTR treated and untreated soils fitted well to Elovich , power function and parabolic models as evidenced by high coefficient of determination (R2) and low standard error(SE). The rates of adsorptiondesorption in the soils studied were greatly influenced by the rate of DWTR added. Specifically, the rate of Ni sorption increased and the rate of released Ni decreased as the amount of DWTR added to the soils increased. The overall findings suggest that Ni retention capacity of soils can be increased via DWTR amendments to provide additional Al- based sorbents. Such information is critical for protecting natural resources, developing improved remediation strategies, and making better risk assessments.

Microbial Contamination of Some Health Care Textile Products in Al-Ahsa Hospitals, Kingdom Saudi Arabia
Textiles are common materials in health care requirements; therefore, hospitals laundering practices are critical to the prevention of transmission of pathogenic microorganisms, which could be the vector of many dangerous diseases. This study was conducted to study the microbial contamination of certain health care textile products in hospitals through both field and laboratory study. The field study revealed the presence of statistically significant relationship between microbial contamination of the hospital type, washing process, washer type, washing practice method, the amount of cleanser materials, as well as bleaching, disinfecting laundry, Ironing type, walls of the laundry, water source, sorting laundry, washing method used, the time of sterilization and storing the washed textiles. The laboratory study which was conducted on some textile products used in hospitals during Laundering processes indicated that difference in the microbial content before and after washing of bed linen was (59 %) (74 %); while the difference was (33 %) (24 %) in doctors’ clothes and for the patients’ garments, it was (56%) (30 %) .This may be due to the density of the threads and the weight per square meter (yar/m2). Microbial genera identified laundry on these textiles samples from different hospitals type revealed that gram negative was more persist laundry treatments and spread more than gram-positive bacteria. On the other hand, yeast species diminished completely after washing and this indicated that the washing agents used had a positive impact on the presence of yeasts.

Immobilization of Phosphorus in Biosolids-Amended Soils by Water Treatment Residual Nanoparticles
Phosphorous mobility in soil environments is largely controlled by P sorption and desorption reactions. This study was designed to evaluate the effects of water treatment residual nanoparticles (nWTRs) at different rates on P mobility in biosolids-amended soils. Sorption and desorption batch experiments were performed on two different soils amended with biosolids at a rate of 3% and 3 rates of nWTRs (0.10, 0.20, and 0.30%). The sorption data showed that nWTRs increased the amount of P sorbed by the biosolids-amended soils with the effect increases as the nWTR application rate increases suggesting that more sorption sites were added on the soil surface as a result of nWTRs addition. The modeling of sorption equilibrium data showed that Langmuir model fit the data much better than Freundlich, Elovich, Kiselev Hill-de Boer, Fowler– Guggenheim, and Temkin models, with relatively higher R2values and smaller standard error of estimates (SE). Whereas, the power function and first order kinetics models provided much better fit for the P adsorption kinetics as evidenced by higher coefficient of determination (R2) and lower SE values. Application of nWTRs with different rates to the clay soil drastically reduced the percentage of desorbed P to 6, 4, and 1% from clay soil and to 12, 7 and 4% from sandy soil at 0.10, 0.20 and 0.30% application rates, respectively. The lack of similarity between adsorption and desorption due to the hysteresis is likely a result of binding to Al/Fe hydroxides. Fourier transmission infrared (FTIR) results indicate the crucial role of surface hydroxyl groups in P retention onto nWTRs.

Morphologgical Changes and Antioxidant Activity of Stevia rebaudiana under Salt Stress
Stevia rebaudiana, a herbaceous perennial shrub contains steviol glycosides, as an alternative source of sugar for diabetic patients. Salinity is one of the limiting factors determining plant distribution and survival in natural ecosystem. The objective of this study was to investigate morphological changes and antioxidant activity of Stevia rebaudiana under salt stress and the ability of tolerance of Stevia plants to salt stress. Plants of Stevia were subjected to different levels of salt (1.58, 2.58, 5.2, 6.60, 10.17 and 13.7 EC mmhos/cm), whereas control plants were watered with tap water. Plant height (cm), plant spread (NS--EW), leaves number per plant, stem numbers/plant, stem fresh weight (g), leaves fresh weight (g), stem dry weight (g), leaves dry weight (g) and antioxidant enzyme activity (peroxidase) were assayed during the different cutting time. All these parameters were found to be severely affected under salt condition. Salt treatment caused an increase in electrolyte leakage compared to control. There is an increase in antioxidant enzyme activity under the high level of salt compared to untreated control plants. The experiment emphasizes that variety of stevia which used under this study can planting in the salt soil until 5.20 EC salt as an agricultural crop to meet the challenges for sugar and energy crisis.

Estimate the Economic Efficiency of the Wheat Crop in the Old and New Land in Egypt
Wheat is one of the major food crops in Egypt and represents the biggest planting areas for the rest of the agricultural crops in the old or new lands, but the production is not enough to cope with rapid population growth may be due to non-optimal use of factors of production used in the production of wheat, so research aimed at measuring the efficiency of resource use used in wheat production by comparing the economic efficiency of it in the old and new land in order to make the most of those resources to take advantage of the increase in production of wheat, and to identify the amount of wasteful in these resources.
Keywords: Economic Ffficiency, Robust Regression, old and new lands.
The important results are:
1- The cultivated area of wheat account for about 37.2%, 24.6% respectively of the total cultivated area, as the value of its production accounts for about 7.1%, 42.3% of the total value of agricultural production, which indicates the extent of the wheat contribution in increasing agricultural production, especially cultivated in the new land, which It has a significant role in increasing production during the study period.
2- Estimating wheat production functions using OLS method in the old lands show that inputs of human labor and pesticides, is located in the third production stage and must work to rationalize the use of these inputs, while in the new lands inputs of Machinery of production is located in the first stage and must work on the concentration of component output to the Economic stage.
3- Using the estimated production function using Robust Regression method to estimated economic efficiency of inputs of production, which was less than the one in the old lands and New, suggesting that the output value of marginal minimum price input, meaning that there extravagance in the use of these inputs must work to rationalize their use.
4- The economic efficiency estimated using DEA analysis is about 93%, 87% in the old and new lands and that there is an opportunity to increase efficiency by 7%, 13%, suggesting that old land is still more efficiently than new in wheat production, as demonstrated by the presence of extravagance in production inputs used in the production of wheat the amount used of human labour, machinery labour, seeds, manure, fertilizers and pesticides was more than optimum by 37.20, 7.7, 25.5 pounds, in the old lands, while it reached in the new lands, 61.46, 50.54, 49.47 pounds.
Find it recommended the need to work to rationalize wasteful production inputs used in wheat production by selecting the appropriate quantities and types and that contribute to the increase in production, both in the old lands or new.

Economic Analysis for Marketing Efficiency and Competitive Advantage for Egyptian Orange Exports
Exports increase in general, agricultural exports in particular is considered one of the methods of achieving prosperity as well as raising the standard of living for community's individuals.
Accordingly, the country aims at supporting its competitive capabilities in global markets, especially for its competitive advantage crops.
The purpose of this research is to identify marketing costs and efficiency of orange crop marketing.
Conclusion shows an increment in both traders and brokers share comparing with producers, which negatively affects the economic situation of producers. Results also show low efficiency in orange crop marketing process, because of the high profit marketing margin that brokers get as a result of their monopolistic practices such as controlling the supply by storing the crop in refrigerators the matter that affects the prices for both producer and customer bearing in mind that orange is storable longer than other fruits.
While studying the competitive advantage indicators of orange exports from Egypt, results show a clear competitive advantage in favor of Egypt compared with other countries except for Morocco and South Africa.
Also, Egypt enjoys a competitive advantage in price compared with its most important competitors in the field of orange export excluding Spain. Egypt achieves a higher proportional production than its competitors excluding Spain.
Market penetration rate weakness for Egyptian orange was recorded compared with some competing countries such as Morocco, Greece, America, South Africa and Spain.
Egypt surpassed all the competing countries in the relative importance of its orange exports, Egypt's annual rate of orange exports is higher than all the competing countries.
Egypt's market share of orange exports to the Saudi and Oman market represents the first rank comparing with its most important competitors. As for the Russian and Kuwait market it occupies the second place and it occupies the forth place for the Dutch market.
While preparing an economic orientation model for Egyptian orange exports the model works to maximize exports return, the model shows that there are several alternatives that introduce a higher return than the current export model.

meat derived it's importance of being a major animal proteins necessary for life and calorie source and reflected meat problem in the local production is unable to cover the consumption of it and thus lower per capita for preventive health limit study aims to estimate and measure the food gap of meat and prospects and to propose a set of policies and procedures that can be introduced to limit the growth of this gap in the future The study used the descriptive and quantitative statistical analysis methods.
The study shown that the local production of red meat increased over the study period 1995-2013 with Annual growth rate of about an average of 2.8%, It is expected that production up to about 1131 Thousand Tons at 2018, 1176 Thousand Tons at 2020, as for The consumption of red meat has an annual growth rate of which was estimated at 2.3 % During the period referred to, It is expected that the consumption of red meat the size of up to about 1329 Thousand Tons at 2018, 1375 Thousand Tons at 2020 .
The Study also revealed that the fish production has increased over the period 1995-2013 at a rate of as much as an annual growth of about 6.8% and is expected to fish production up to about 1.7 , 1.8 million tons in 2018, 2020 respectively while consumption has been estimated annual growth his rate of about 5.8% and shows consumption forecasts of fish consumption to reach about 1.9 million tons a year 2018 ,2 million Tons in 2020.
The study suggested that agricultural policies focused during the next phase on four main themes to limit the growth of red meat, fish gap.
1- Increasing poultry and fish meat production.
2- Improving the efficiency of utilized resources in livestock production.
3- Implementing Structural changes to improve the efficiency of livestock and livestock products marketing system.
4- Benefiting from the Arab free trade area and African commessa in implementing joint projects for animal production and trade.

Economic Study for Slaughtered Red Meat Case Study on Faculty of Agriculture Slaughterhouse, Alexandria University
Animal production sector is the main source of animal protein represented in red meat production, which amounted to about 941 thousand tons in 2014, Self-sufficiency ratio was about 72% of the same year. The stage of animal slaughter did not receive sufficient attention so far, both from research or government organization in spite of its importance. The numbers of slaughterhouses in Egypt are 474, and only four slaughterhouses exist in Alexandria. In 2013, the numbers of slaughtered cattle in governmental slaughterhouse in Alexandria were 70.39 thousand head (4.45%) comparing with 1.58 million heads were slaughtered in whole Egypt. The aims of current study were to show the most important operations carried out within government slaughterhouses and knowing their important economic and technical aspects using the published data in central agency for public mobilization and statistics (CAPMS) and preliminary data from research sample at faculty of agriculture slaughterhouse in period of 2006 to 2015. In order to, estimate the periodic fluctuations and economic performance of slaughtered animals. The researcher has adopted to achieve those goals on the descriptive method of economic analysis, statistical analysis.
The results of current study were: The minimum average of monthly seasonally fluctuations of slaughtered animals were 80.7 % and the maximum average was 114.91%. 3) the higher slaughtered animals were concentrated in 7 months January, July, August, September, October, November and December, where the percent rate of slaughtered animals for those months were 103.43%,114.91%, 114.03%, 108.56%, 106.18%, 101.14% and 104.86% respectively. And through the performance evaluation of the slaughterhouse it shows that the benefit cost ratio amounted to about 9.18, which means that the slaughterhouse in the best investment than the banks investment. Furthermore, the net profit of slaughterhouse was 3.68 million Egyptian pounds in 2015, the return on slaughtered animals was 89.1% and worker productivity was 21.46 thousand Egyptian pounds in the slaughterhouse of the research sample.

An Economic Study of the Consistency of the Poverty Line with Welfare in the Arab Gulf Cooperation Council
The search aims at estimate the absolute poverty line in GCC, for compare it with the international poverty line, to identify the consistent with welfare in those countries. A search depends on World Bank data for the GCC countries during the period (2001-2014) in the cross-series form to estimate consumption and saving functions. To estimate the absolute poverty line at the level of the Arab Gulf Cooperation Council (GCC), dividing the study period (2001-2014) to three periods: the first period (2001-2004), and the second period (2005-2009), and the third period (2010-2014). The results of those periods that increase the per capita income of about $ 100 / year, leading to increased consumer spending per capita per year by 47,12,3 $ for the three periods, respectively. The absolute poverty line of the individual countries of the Arab Gulf Cooperation Council for the three periods was about 1420.5, 6754.7, 9963.1 USD / capita / year which is equivalent to 3.9, 18.5, 27.3 $ / person / day for the three periods, respectively. this means that an individual during those periods in which his income equivalent to 3.9, 18.5, 27.3 dollars / day has not spared any part of his income (savings is equal to zero), where barely enough to meet consumer needs, and that the individual who is earning less than this limit will not be able meet his needs.
This confirms that those countries use a higher consumption pattern of welfare in determining the poverty, which exceeds global absolute poverty line, which amounts to about $ 2.25 / person / day. Moreover, the Arab states of the low hunger index compared to all the nations of the world. Therefore, the study suggests that the Gulf Cooperation Council are using the highest consumption patterns of welfare in determining the poverty, which exceeds global absolute poverty line. This means that the GCC Arab poverty line is consistent with the economic welfare of those countries. Hunger Index results also revealed that the GCC Arab states of low hunger index compared to all the nations of the world. In addition, the national absolute poverty line for these countries is higher than in the United States and lower than in Luxembourg in the last two study periods.

The Economic Impact of Using Wastewater Triple Treatment in Agricultural Irrigation of Al-Ahsa Oasis in Saudi Arabia
The study aims at measuring the impact of using wastewater triple treatment on the productivity, total costs, and profitability of palm and lemon crops, The study area includes three zones within the irrigation and drainage project Ahsa, irrigated two types of water (ground water, and wastewater triple treatment) which Mansoura, Alhara and Jlijlh, A stratified random sample of 290 Farms was taken and distributed into three zones according to the number of irrigated farms in all of them, Descriptive and quantitative analysis are used in this. T-test, a correlation coefficient and dummy variables are utilized to estimate the difference between two types of water, The results showed a positive relationship between the wanted farmers on using wastewater triple treatment in irrigation and type of tenure, full-time farming, family size, education level, while inverse relationship the old, and holding size (dunum). Using T test showed a significant difference between the two means, perhaps due to the lack of groundwater quality because of increased salinity, especially in the north of the oasis bordering the Arabian Gulf. Using dummy variables show an increase productivity of Alrziz Palm, Alkhallas Palm, lemon tree that's irrigated with waste water triple treatment therapy significant increased by 10.1, 5.3, 12.0 kg from those that are irrigated with groundwater respectively, While showing low amount Al -basr by 3.1 kg compared to their irrigated with groundwater.
The results also pointed to a rise in profit margin and total productivity and yield of dunum and a decrease in the amount of irrigation water and then rise in unit revenue and water productivity of crops study when using wastewater- triple treatment compared to irrigation groundwater, As it turns out that the use of wastewater treatment for irrigation substitute for use in fertilizer additions because there are some necessary nutrients for plant growth certain concentrations within the safe limit, which will reflect positively on the farms, which can provide about 33%, 32.5%, 55.5%, 80%, 100%, 20% of the total amount of water used, manure, nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, and the number of human labor hours, respectively. The research suggests the following recommendations:
- Educate farmers and increase their knowledge of the nature of this type of irrigation water and the content of essential nutrients, whether organic fertilizer or metal ones.
- Encourage farmers to use wastewater triple treatment in agricultural irrigation to increase economic returns as a result they have to increase productivity in terms of reducing costs on the other.
- Oriented the Agricultural Extension Department of Irrigation and Drainage Authority Ahsa out the recommendation in fertilizer fit with the results obtained and their impact on the farmer and the environment.
