Three patterns of release for the parasitoid Eretmocerus mondus were compared with a low rate of Encarsia Formosa on the whitefly in sweet-potato fields. The patterns of Ere. mondus included that fixed weekly release number (3females/plant/week), variable release (5 females/plant/wks 7) follow (1 females/plant/wks 7), low release rate (1 females/plant/wk), while a low release of Encarsia Formosa at (1 females/plant/wk) was compared. The control was without parasitoid releases and whitefly nymphal densities reached 33100 individuals /50 leaves after 10 weeks. In patterns of parasitoid release, percentage parasitism was 77.9% by fixed-rate Ere. mondus after 8 weeks, while it was 47.5% with variable rate Ere. mondus after 6 weeks. The low-rate of Ere. mondus and E. Formosa induced 64.5%, 62.0%, respectively after 14 weeks. Releases of low numbers of E. formosa provided commercially acceplable whitefly control. There was no difference between the fixed and variable release rate treatment of Ere. mondus, indicating a high percentage of parasitism as a result of absence the host whitefly and honeydew increasing on the leaves. Also, the results proved that the low release gave satisfactory reduction on whitefly population and suitable parasitism percent to occur parasitoids continuously.

Planning for sustainable utilization of agriculture sector depends on possibilities to get accurate and enough information of the studied area. This is rather essential for scientific planning, implementing updated technologies, removing constrains and controlling environmental desertification. Also, it is critically needed to introduce new investments for the agricultural sector aiming to improve and develop new area for optimum agricultural production. Moreover, accurate data of the proposed IS-SAH are urgently needed to face day by day constrains of sustainable agriculture. Geographic map of the country is divided into horizontal sectors not more than 9 starting from the north direction; each sector is divided into vertical sub-sectors not more than 9 starting from the west. Each sub-sector is divided into horizontal locations not more than 9 starting from north. So, each location is representing by a directory of 3 numerical values starting from 111 and not more than 999. The meaning of the numerical value of each location, starting from the left; first is the number of the sector, second is the number of the sub-sector and third is the number of location. If the location is of wide area, it may be divided into vertical areas starting from the west, each denoted by a character e.g.: A, B, C, …up to Z (i.e. 26 areas), which is added at the right of the location numerical value e.g. 158-A, 228-B…etc. in vertical arrangement starting from the west. On the basis of this grid-system, the locations (and their areas) are cited on a geographic map of the country showing its numerical values and the site of the studied area. On level of different countries, the above details are to be conducted with each country, then the country name is to be added at the left of the numerical value of location and separated by a dash e.g. Egypt-198-G, Saudi-337-H, Sudan-828-D, …etc. The directory of each location comprises the following sub-directories: 1-Site details, 2-Soil resources, 3-Water resources, 4-Climatic conditions, 5-vegetative growth, 6-Dynamic strategies and scientific planning, 7-Updating the information unit at intervals, 8-Training and recruiting needs for development, 9-Facilities need for development and 10-Evaluation of Salinity and alkalinity hazards of location. Each of these sub-directories comprises different sub-sub-directories and the concerned files (as needed for the studied location). All directories of locations and/or area are connected with the (IS-SAH) in harmony with scientific planning for all locations, which will be subjected to updating activities that needed for sustainability and development of the agricultural sector in the studied country or on the level of different countries. As applied example for the IS-SAH, the available inputs of the area denoted as Egypt-353-S are presented and evaluated for combating soil salinity, alkalinity and waterlogging hazards.

The present study was carried out during two successive seasons 2006 and 2007, on Hayany date palm cultivar grown at four locations differed in environmental pollution in Alexandria Governorate. (A) Mostafa Kamel street as indicated to manufacturing and high way area, (B) Air port road as a density of settlement and traffic area, (C) El-Montaza Garden as a high density of plants and vehicular traffic and (D) El-Mamoura Botanical Garden (Horticulture Research Institute) as a palm trees orchard, fare from the major road about 700 meters. The effect of environmental pollution on pinnae composition, fruit set and fruit quality was studied. Soil analysis for every location were taken at two depths 0-30 cm and 30-60 cm to determine some heavy metals (Cd and Pb) content. Regarding the yield, highest yield was obtained at locations (C) and (D), while it was the lowest at, locations (A) and (B). Fruit set percentage was lowest at location (B) in comparison with other tested regions. Concerning physical properties, significant differences in fruit dimension, weight and flesh/fruit weight percentage they showed greater values at location (D) and lower at location (B). As for chemical properties, total sugars content was significantly higher in fruits at location (C), whereas it was the lowest at location (D), such differences were significant. Regarding T.S.S%, the differences between tested locations did not reach the level of significant. Fruits of “Hayany” had lower tannins percentage at location (A) as compared with other locations; no significant differences were detected in this respect between other three tested locations. Concerning effect of environmental pollution on some minerals content in fruits and pinnae, nitrogen, potassium and lead content in fruits increased in location (A) than other locations. Phosphorus content was significantly higher at location (D), whereas, it was the lowest at location (B). Cadmium content was not found in fruits or pinnae among all tested locations. As for pinnae mineral content, at location (C); nitrogen was the lowest, whereas phosphorus was the highest in comparison with other tested locations. Regarding potassium content, it gave highest value at location (D) than other locations. No significant differences were detected in pinnae lead content among tested locations. The results of this study emphasize that Hayany date palm cultivar was not affected by pollution contamination.

Residues of azoxystrobin (Amistar 25% SC), fenhexamid (Telidor 50% SC) and lufenuron (Match 5% EC) were determined on grapes treated with recommended doses. Grape leaves and fruit samples randomly collected after 1hr, 1, 3, 6, 10, 15 and 21 days of application, were extracted, cleaned-up and analyzed using chromatographic methods. Azoxystrobin, fenhexamid and lufenuron residues were dissipated on grape leaves after ten days of treatment by 87.83, 99.23 and 99.29% of the initial concentration, respectively. The corresponding values for dissipation of mentioned pesticides on grape fruits were 93.55, 99.62 and 99.99% of the initial concentration, respectively. The pre-harvest intervals (PHI) were calculated to be 6, 10 and 7 days after application of azoxystrobin, fenhexamid and lufenuron on grapes, respectively.

In the present study, the nitrification inhibitor, DMPP (3,4-dimethyl pyrazole phosphate) was used for inhibiting the nitrogen transformation and reduced the nitrate leaching in two types of soil, i.e. sandy loam and sandy clay loam. Soil columns (5 cm diameter and 24 cm length) were packed with soil at bulk density of 1.5 g/cm3. Nitrogen fertilizers (urea and ammonium sulphate) were applied at rate of 150 mg N/column. The soil columns were leached with 150 ml water/5 days and the leachate was collected. The experiment was lasted 40 days. At the end of experimental period the soil was pushed out the columns and sectioned at 5 cm pieces, then extracted for N-NO3- and N-NH4+ .The results showed that DMPP with urea or ammonium sulphate significantly reduced NO3- -N leaching. The cumulative leaching losses of soil nitrate under treatment of urea or ammonium sulphate with 1.0% DMPP, from columns of sandy loam soil were 34.7 and 40.6% and from column of sandy clay loam soil, were 51.7 and 43.4% lower than those of soil columns tested with urea or ammonium sulphate application only within the 40 days observation, respectively. The results also showed that nitrification rate (NR), was reduced as a result of DMPP application. The nitrification rate was reduced from 53.96 (with urea only) to 36.46% (with urea treated with DMPP) and from 65.92 (with ammonium sulphate only) to 27.92% (with ammonium sulphate treated with DMPP) in case of sandy loam soil. The corresponding values in case of sandy clay loam soil were from 60.70 to 43.76 % and from 67.46 to 36.59%, respectively. Also, the inhibition percentage of nitrate was 32.43 and 57.64% with urea and ammonium sulphate treated with DMPP, respectively in case of sandy loam soil. The corresponding values were 27.91 and 45.77%, respectively in case of sandy clay loam soil. It is proposed that DMPP could be used as an effective nitrification inhibitor to control nitrification process, decline N leaching, and increase the utilization efficiency of applied nitrogen fertilizers besides saving the fertilizers and labor costs.

A one-way diallel cross among five common wheat genotypes were evaluated in F1 at Etay El-Baroud Agricultural Research Station during 2005/2006 and 2006/2007 seasons to study some genetical parameters. Mean squares of genotypes were highly significant for all characters in F1. Parents vs crosses mean squares, as an indication to average heterosis overall crosses, were found to be highly significant for number of spikes/ plant, number of grains/spike and 1000-kernel weight. (GCA) and (SCA) mean squares were highly significant for all studied traits. Also, GCA/SCA variance ratio were found to be greater than unity for all traits except grain yield /plant. The additive variance (D) was significant for all studied traits except number of kernels/ spike and grain yield/ plant. Dominance components of variation (H1) and the dominance effects associated with gene distribution (H2) were highly significant and greater than (D), for all characters. The overall dominance effects of heterozygous (h2) were significant for number of spikes/plant and number of kernels/ spike. The covariance of additive and dominance (F) was significant for heading and maturity dates. (H1/D) ½ showed the presence of overdominance for most traits. Low heritability narrow sense values were detected for all characters. Therefore, selection would be more effective in postponed to the advanced generations.

In an attempt to achievea better diet for rearing larvae of the silkworm Bombyx mori and increase its productivity, different antiseptics were added to a recommended basic semi – artificial diet to prevent contamination with yeasts and molds. The tested antiseptics were potassium sorbate, propionic acid and delvocid. The results indicated that all these materials were effective in extending the shelf life of the diet as well as improving the rate of growth and productivity of silkworm B. mori. The maximum improvement in all tested criteria was occurred with supplementing delvocid to the diet, in comparison to the other tested materials.

This investigation was carried out at the experimental farm of Etai El-Baroud Agricultural Research Station, El-Beheira Governorate (Agricultural Research Center) during the two successive growing seasons 2006/2007 and 2007/2008. Five bread wheat cultivars and lines, Triticum aestivum L. en Thell, representinga wide range of diversity for several agronomic characters were selected for the study. The five parents and ten crosses were grown in a randomized complete block design with three replications with recommended fertilization. The genetic analysis (variance, combining ability, heterosis, and path coefficient analysis) of grain yield per plant and some agronomic traits, i.e., (days to anthesis, days to maturity, plant height, spike length, number of tillers/plant, number of spikes/ plant, number of grains/spike and 1000-grain weight) were evaluated. Differences among parents and hybrids were significant. Highly significant heterosis was depicted in two crosses (P1´ P3) and (P1 ´ P2) for grain yield/plant.Three parental combinations; (P1´ P2), (P1×P3) and (P1´ P5) expressed significant specific combining ability effects for grain yield/plant. The Number of grains/spike followed by 1000-grain weight proved to be the major grain yield contributors.

Field investigation was carried out during 2006/2007and 2007/2008 seasons on Zaghloul and Samany date palm cultivars grown in Alexandria, Egypt to study the effect of different sources of nitrogen namely, city garbage as organic source and urea or ammonium nitrate as chemical sources on yield, fruit quality, and some minerals content on fruits and pinnae, moreover chlorophyll content in pinnae. Applying 1200 g N/palm/year from city garbage alone or in combination with chemical nitrogen sources improved yield, fruit length and fruit diameter while fruit weight was not affected significantly by the different treatments in both cultivars. TSS and total sugars content were highly when trees fertilized with city garbage in combination with urea for Zaghloul and Samany cultivars. City garbage decreased chlorophyll content in pinnae of Zaghloul and Samany. The highest value was obtained with control (1200 g N/palm/year from ammonium sulphate as well as 10 kg cattle manure) and urea in Zaghloul and Samany, respectively. Fruit and pinnae mineral content (N, P, K and Mg) was not affected significantly by the different treatments in both cultivars. As for the effect of fertilization treatments on fruit heavy metals,in both study seasons the highest value of cadmium in Zaghloul and Samany fruits were recorded when trees treated with combined urea with city garbage. Concerning fruit lead content the highest concentration was obtained with ureaand combined urea with city garbage in Zaghloul and Samany, respectively.

A field experiment was conducted during agricultural growing season of 2005-2006 on three sites of newly reclaimed loamy sand soils irrigated with low qualities of irrigation waters derived fromBahr Wahbey water, Bats drainage water and blending water of Bats mixing station at Fanos Village, Tamia district, Fayoum Governorate. The experimental treatments were designed to study the negative effects of the used low water qualities on both the newly reclaimed soils and sugar beet characteristics as well as to clarify the optimized rate of the used farmyard manure (FYM) which was integrated with local gypsum as soil amendments to alleviate the hazardous effects of these irrigation water on soil properties and both sugar beet yield and its quality. The applied rates of the tested soil amendments were 0, 15, 30 and 45m3 FYM /fed and 0, 2, 4 and 6 ton gypsum/fed, and thoroughly mixed with the tested soil plots before planting sugar beet, which their root yields were harvested after 180 days from planting. Soil physical and chemical properties were determined for each of the studied treatments after sugar beet harvest, thereafter, root yield and its quality were also measured The obtained results showed that the short-term use of the low water qualities for irrigating sugar beet plants left their negative footprints on the tested soil properties as well as root yield and its quality parameters under study, particularly in case of soil plots received Bats saline drainage water. However, the values of soil bulk density, hydraulic conductivity, available water were tended to decrease vs. an increase in each of soil pH, ECe and ESP, besides a noticeable reduction in the vegetative growth, root yield and its quality parameters of sugar beet, taking into consideration that the changes in the majority of these characteristics reached the level of significance. On the other hand, application of FYM and local gypsum as solely or together was associated with an ameliorated effect on each of the aforementioned characteristics concerned with either the experimental soil or sugar beet, with a significant positive effect being at the combined treatments. That was true, since the treatments of (30 m3 FYM /fed + 4 ton gypsum /fed) and (45m3 FYM /fed + 6 ton gypsum /fed) gave the best improvement efficiencies on root yield of + 43.90 and + 44.60 % with site I; + 45.80 and + 46.50 with site II and + 21.10 and + 21.5 with site III over the control treatment, respectively, but the difference between these two treatments in the studied characteristics of both soil and plant didn’t reach the level of significance. Such ameliorated effects in soil properties were positively reflected on root yield and its quality of the grown sugar beet plants. Thus, it is noteworthy to mention that the treatment of (30 m3 FYM /fed + 4 ton gypsum/fed) is considered the best one from the economical point of view. So that, it could be recommended that organic manure integrated with gypsum should be applied to alleviate the hazardous effects of long-term use of low qualities of irrigation waters on soil properties and to achieve sustainable root yield of sugar beet.

Field experiments were conducted at the experimental farm of the soil salinity and alkalinity laboratory at Alexandria, Egypt during the growing season (May-September) in two consecutive years, i.e., 2007-2008 to assess the agronomic potential of the organic compost thus obtained for growing maize, and comparing the effect of this compost supplemented with mineral fertilizer with the conventional mineral fertilization on maize yield and on macronutrients concentrations and uptake in the plant tissues. The results of this study revealed that in all fertilizers treatments, significant increases in available macronutrients concentrations in soil were observed in the minerally and organically amended plots, and there was no significant difference between mineral and organic plots. However, the combination between mineral and organic fertilizers (T10, 25% mineral fertilizer + 75% organic fertilizer) had the highest value of available macronutrients concentrations compared to the other fertilizers treatments. It is interesting to emphasize that the highest values of macronutrients concentrations were observed with combination fertilization (T10) followed by T11(50% mineral fertilizer+ 50% organic fertilizer) and T12(75% mineral fertilizer + 25% organic fertilizer). Similarly, the highest grain and stover dry matter yields were obtained at the combination of mineral fertilizer by the rate of 25% and organic fertilizer by the rate of 75%. The increased values of grain and stover yields at the organic plots and the plots fertilized with both mineral and organic fertilizers may be associated with beneficial changes in soil N, P, K and organic matter dependent soil properties. There were significant positive relationships between N uptake, kg.ha-1[R2 (1st season) = 0.94, R2 (2nd season) = 0.95], P uptake, kg.ha-1 [R2 (1st season) = 0.95, R2 (2nd season) = 0.97] and K uptake, kg.ha-1 [R2 (1st season) = 0.96, R2 (2nd season) = 0.95] and maize grain yield in the two years. This study demonstrated that use of combination of organic and mineral fertilizers in field experiment improved soil fertility, yields and nutrient concentration in the crops compared to mineral fertilization.

Toxicity effect of Dipel-2X, and three insect growth regulators IGRs: Diflubenzuron; Spiromesifen and Pyriproxyfen, were determined against 2nd larval instar of Spodoptera littoralis. The results showed that Diflubenzuron was the most potent toxicity followed by Spiromesifen; Pyriproxyfen, and Dipel-2X. The effect of LC50 of the tested IGRs on the in vivo inhibition of chitinase from Spodoptera littoralis was assayed. The interaction effect of Dipel-2X with IGRs was investigated. Results proved that pretreated of Dipel-2X with IGRs caused more toxicity effect than single treatment. The sensitivity of chitinase activity to the three tested IGRs was measured by the I50 values. The I50 values of Diflubenzuron; Spiromesifen and Pyriproxyfenon Lab strain larval chitinase are 0.54, 0.60 and 0.73µM respectively. While the I50 values are 0.60, 0.72 and 0.81µM respectively against Field strain. The results proved that chitinase was sensitive to the IGRs. Generally, Dipel-2X pretreated with IGRs will produce a new trend so as increase toxicity of the bioinsecticide, enhance the role of beneficial insects. The results of the present study may add some forward steps to use bioinsecticide as alternative to conventional insecticides especially against this insect. So, the tested compounds can be involved in important steps necessary for successful IPM programmes applied against S. littoralis.

Two field experiments were conducted at the Experimental Farm of Faculty of agriculture Damanhour Branch, Alexandria University at El-Bostan region to evaluate the effects of phosphorous solubilizing bacteria( PDB) (Bacillus megaterium as a commercial product Phosphorein), and Vesicular Arbuscular Mycorrhiza (Glomus macrocarpium) with four different fertilization levels of inorganic phosphorus (0, 30, 60 and 90 kg P2O5 fed.-1) on the growth, seed yield, seed protein, N, P and K contents of seeds of common bean (Phaseolus vulgaris L.) cv."Bronco". The results revealed that Inoculation of common bean seeds with Mycorrhiza gave significantly higher mean values of dry seed yield fed.-1 than those inoculated with Phosphorein in both seasons also the inoculation of common bean seeds with Mycorrhiza or Phosphorein and application of 60 or 90 kg P2O5 fed-1. was the best combined treatment Moreover, inoculation with VAM or PDB under the applied P-mineral levels supply reflected significant difference on the percentage of N, P and protein content in dry seeds in both seasons. Polynomial quadratic models were established and used to describe seed yield responses of bean plants inoculated with Phosphorein or Mycorrhiza in combination with four different levels of P-mineral. The equation constants were used to calculate maximum rates of P fertilizer (Pmax) and the corresponding maximum yields (Ymax.) for all treatments.

the identification of both the internal design and the privacy element of housings in Riyadh city, on a sample of 175 of the families of female students in the department of housings and home management in the faculty of education for home economics, research data were collected from field by interviews via questionnaire .The results reveal the following:
1. Most of sample members dwell in housings of 7 to less than 15 years old, and the majority of these housings are composed of a suite annexed to villa (70.5%), also it is revealed that 44.3% of these housings combine both the traditional as well as the modern style, also it is clear that the internal spaces in it is distributed between the different daily usages.
2. There are spaces characterized by high degree of privacy and is concordant with criteria of good design, represented by a reception (male and female) and a living room.
The majority of respondents have high perception as regards to privacy criteria represented by insulation of internal and external walls and the use of reflecting glass.
The problem of inefficacy of external fences to satisfy privacy, comes on the top of current existing problems in housings of the respondents.
The internal design of housing understudy, as an independent variable, accounts for explaining 13.6% of the variance in the degree of privacy as a dependent variable.
