<strong>The dissipation and residual levels of penconazole and imidacloprid in squash fruit under field condition were determined by using GC-ECD and HPLC-DAD with QuEChERS method. The dissipation half-life time of penconazole and imidacloprid residues in squash fruits were 1.95 and 1.93 days, respectively. According to maximum residue limit (MRL). The pre harvest interval (PHI) of penconazole and imidacloprid were 10 and 7 days after application for squash fruits, respectively. This suggested that the use of squash fruits treated with these pesticides were safe for consumption. This study might be useful to prevent health problem from consumers. </strong>

<strong>In the present study, dried Moringa oleifera leaves </strong><strong>powder (DMLP) were incorporated at different levels (5,</strong><br /><strong>10 and 15 %) in cookies and their sensory and nutritional </strong><strong>properties were evaluated. The results revealed that the </strong><strong>contents of protein, dietary fiber, minerals in cookies </strong><strong>increased with incorporation of increasing levels of </strong><strong>DMLP. Sensory evaluation showed that cookies with </strong><strong>acceptable quality and typical Moringa leaf flavor could be </strong><strong>obtained by incorporating DMLP up to 10 %. Thus, the </strong><strong>nutritional quality of cookies could be enhanced by </strong><strong>incorporating DMLP in a dose dependent manner.</strong>

<strong>Bioassays were carried out for evaluating the toxicity </strong><strong>of different insecticides against the susceptible strain of </strong><strong>cotton Leafworm, Spodoptera littoralis (Boisd.). Toxicity </strong><strong>data based on LC50 values indicated that the proclam® is </strong><strong>more toxic insecticide against the laboratory strain, while, </strong><strong>the OP syclon®was less toxic. Esterase isozymes exhibited a </strong><strong>wide range of variability among the pupae and larvae. </strong><strong>Two common bands were detected among all samples in </strong><strong>pupae and larvae. Proclam showed one band in pupae</strong><br /><strong>(Es.C2) compared with other treatments and in larvae </strong><strong>detected one band in (Es.C3) and detecte the highest band </strong><strong>number (6 bands) comparing with other insectcides. The </strong><strong>results of biochemical analysis showed that there is </strong><strong>arelationship between the resistance to insecticide and the </strong><strong>increase of enzyme activity such as esterase enzyme. Five </strong><strong>out of ten oligonucleotide primers (50%) used in the</strong><br /><strong>RAPD analysis gave unique markers. Out of the five </strong><strong>primers, two detected single unique markers (OPA-02 and </strong><strong>OPA-15), two gave two markers (OPA-05 and opc-02), and </strong><strong>one yielded three unique markers (OPC-12).Additionally, </strong><strong>compared with the control worms, cotton leaf worm </strong><strong>exposed to insecticides recorded the emergence of 7 new </strong><strong>fragments from 98 total fragments. So, the total number of </strong><strong>fragments which disappeared in response to both </strong><strong>treatments was 98 fragments. Exposure to insecticides at all </strong><strong>concentrations revealed the increase or decrease the </strong><strong>number of amplified polymorphic DNA and increased gene </strong><strong>expression in comparison to control cotton leaf worm.</strong>

<strong>Desert development is the key role of enhancing </strong><strong>agricultural production in Egypt. The northwestern coast</strong><br /><strong>is one of the most attractive desert regions for sustainable </strong><strong>agrarian development due to its abundant qualifications </strong><strong>which have not sufficiently used yet. This investigation was </strong><strong>carried out in El-Qasr - Um El-Rakham area as a model </strong><strong>for rainfed pattern at the northwestern coast, to assess </strong><strong>both of types and capability of the soils representing </strong><strong>dominant land forms in the area. Studied area extends </strong><strong>over about 159603 feddan including 12 drainage basins.</strong><br /><strong>The extent of landforms was spatially identified using </strong><strong>geological and topographic maps in integration with DEM. </strong><strong>The area represented by 6 main land forms; (1) Coastal </strong><strong>plain (17.8%) which include: Alluvial fans (9.1%), </strong><strong>Lagoonal depression and salt marsh (3.5%), Oolitic </strong><strong>longitudinal sand dunes (2.2%) and Oolitic sand beach </strong><strong>(2.8%) – (2) Alluvial terraces and Interfluves wadis (9.7%) </strong><strong>– (3) Wadi course (2.7%) – (4) Escarpment (4.3%) – (5) </strong><strong>Piedmont plain (13.6%) – (6) Plateau (52.1%) which </strong><strong>include: Lower plateau (18.6%) and Higher Libyan </strong><strong>plateau (33.5%).</strong><br /><strong>Soils of the area were surveyed through 261 soil </strong><strong>profiles which spatially distributed upon ETM+ </strong><strong>LANDSAT 7 image classification to represent achieved </strong><strong>landforms. Twenty four representative soil profiles were</strong><br /><strong>selected in this study. A digital vector database was </strong><strong>created using GIS, consequently, soil and evaluation maps </strong><strong>were generated. Results indicated that ten soil mapping </strong><strong>units were differentiated according to differences in profile </strong><strong>depth, texture and topography properties in the area </strong><strong>under study. Further, data emphasized that 13.6% and </strong><strong>19.6% of the total area, respectively have deep and </strong><strong>moderately deep profile depth. Coarse to moderately </strong><strong>coarse texture classes dominated whole soils. Almost flat </strong><strong>topography to gently undulated conquered the area over </strong><strong>69.3%.</strong><br /><strong>Based on field check and laboratory analysis, soils </strong><strong>were classified into 10 family classes, while at sub great</strong><br /><strong>group level seven classes were differentiated. These are </strong><strong>Typic Torrifluvents (24259 F – 15.2%), Typic</strong><br /><strong>Torripsamments (28728 F – 18.0%), Lithic Torripsamments </strong><strong>(36070 F – 22.6%), Lithic Torriorthents (56978 F – 35.7%),o</strong><strong>olitic Torripsamments (7980 F - 5.0%), Typic Aquisalids </strong><strong>(5586 F - 3.5%), and Typic Haplosalids (260 F -0.15%).</strong><br /><strong>Soils of oolitic sand beach were classified as Oolitic </strong><strong>Torripsamments, while soils of the lagoon depressions and</strong><br /><strong>salt marsh were classified as Typic Aquisalids. Soils of </strong><strong>alluvial fans were classified as Typic Torrifluvents. As well, </strong><strong>soils of the alluvial terraces and interfluves wadis, </strong><strong>piedmont plain and wadi courses are generally belong to </strong><strong>the subgroups Typic and lithic Torripsamments and </strong><strong>Torriorthents, except small areas in the alluvial terraces </strong><strong>and interfluves wadis and the lower portions of wadi </strong><strong>courses were classified as Typic Torrifluvents and Typic </strong><strong>Haplosalids. Generally, soils of plateau are classified as </strong><strong>lithic Torriorthents.</strong><br /><strong>The study concluded that, soil potentiality classified as </strong><strong>"Good" over 13.6% of the area, including soils of alluvial </strong><strong>fans, partially alluvial terraces and down streams of wadi </strong><strong>courses landforms, where the potentiality index varied </strong><strong>between 60.9 and 68.1%. Meanwhile, the potentiality was </strong><strong>classified as "Fair" on 19.6% of the area, representing </strong><strong>some soils of alluvial fans, alluvial terraces, wadi middle </strong><strong>streams and piedmont plain landforms, where the </strong><strong>potentiality index ranged from 42.5 to 57.0%. "Poor" </strong><strong>potentiality unit extend over 22.6% of the area occupying </strong><strong>some soils of alluvial terraces, wadi upper streams and </strong><strong>piedmont plain landforms, as the potentiality index ranged </strong><strong>from 30.5 to 36.8%. Potentiality indices ranged between</strong><br /><strong>1.2-11.5% indicating "Very poor" and "Non agricultural" </strong><strong>units over the rest of the area, which may be relevant to </strong><strong>other land utilization types. Low soil potentiality associated </strong><strong>with limitations related to; limited soil profile depth, poor </strong><strong>drainage, coarse texture, low clay content, high salinity, </strong><strong>high lime content and low fertility status.</strong>

<strong>Field studies were conducted in two different locations </strong><strong>at El-Behira Governorate, in 2013 and 2014 cotton seasons </strong><strong>to evaluate some insecticide treatments against cotton </strong><strong>leafworm (CLW), Spodoptera littoralis (Boisd.).</strong><br /><strong>Glutathione S-transferase (GST) and esterases activities in </strong><strong>the CLW larvae from the two locations were compared.</strong><br /><strong>Spinetoram (field rate (FR)) / lufenuron (0.5 FR) mixture </strong><strong>achieved the highest %reduction of CLW larvae, followed </strong><strong>by fipronil (FR) / lufenuron (0.5 FR) mixture which are </strong><strong>followed by spinetoram (FR) and fipronil (FR). At </strong><strong>AbouElmatameer, spinetoram / lufenuron mixture achived </strong><strong>CLW %reduction of 90.3, 92.5, 91.5, 89.8 and 86.5% in </strong><strong>2013 and 90.8, 94.5, 90.3, 85.8 and 83.0% in 2014 season </strong><strong>after 1-, 3-, 5-, 7- and 10-days of treatment, respectively.</strong><br /><strong>The same mixture reduced CLW larvae numbers by 91.3, </strong><strong>91.0, 89.0 85.8 and 83.3%, in 2013 and 91.0, 92.0, 91.0 90.3 </strong><strong>and 88.3% in 2014 after 1-, 3-, 5-, 7- and 10-days of </strong><strong>treatment, respectively, at Shobrakeate. On the other </strong><strong>hand, cypermethrin and chlorpyrifos treatments achieved </strong><strong>the least %reduction of CLW larvae. Mixing the 0.5 FR of </strong><strong>lufenuron with the tested insecticides (chlorpyrifos, </strong><strong>cypermethrin, fipronil and spinetoram) resulted in </strong><strong>increasing their efficacy against CLW. Statistically, field </strong><strong>performance of cypermethrin, chlorpyrifos and </strong><strong>cypermethrin / lufenuron (0.5 FR) mixture were higher at </strong><strong>Shobrakeate than at AbouElmatameer in both seasons </strong><strong>2013 and 2014, where other insecticide treatments were </strong><strong>comparable. AbouElmatameer CLW strain showed </strong><strong>significantly higher esterases and GST activities about 2-</strong><br /><strong>fold compared with that of Shobrakeate one in both </strong><strong>seasons. From these results, fipronil and spinetoram can</strong><br /><strong>be good alternatives and can be used alone or in a </strong><strong>combination with lufenuron to improve the CLW control</strong><br /><strong>and overcome the insecticide resistance.</strong>

<strong>Toxicity and sublethal effects of emamectin benzoate, </strong><strong>novaluron and diflubenzuron were evaluated against the </strong><strong>2nd instar larvae of cotton leafworm (CLW). The joint </strong><strong>toxic action of emamectin benzoate with novaluron or </strong><strong>diflubenzuron was carried out. Emamectin benzoate (LC50 </strong><strong>= 0.014 mg L-1) was 264.3 and 5707.1 times more toxic </strong><strong>than novaluron (LC50 = 3.7 mg L-1) and diflubenzuron </strong><strong>(LC50 = 79.9 mg L-1), respectively. Novaluron was </strong><strong>approximately 21.6 times more toxic than diflubenzuron. </strong><strong>After 24 hrs of exposure, all mixtures of emamectin </strong><strong>benzoate (at LC10 or LC25) with novaluron or </strong><strong>diflubenzuron (at LC10 or LC25) resulted in antagonistic </strong><strong>effects with co-toxicity factors (CTFs) ranged between -25 </strong><strong>to -700 except the mixture of emamectin benzoate at LC10 </strong><strong>with novaluron at LC10 (CTF = 60). Mixtures of </strong><strong>emamectin benzoate at LC10 with novaluron at LC10 and </strong><strong>emamectin benzoate at LC25 with novaluron at LC25 </strong><strong>resulted in potentiating effects after 48, 72 and 96 hrs of </strong><strong>exposure. On the other hand, all mixtures of emamectin</strong><br /><strong>benzoate with diflubenzuron resulted in antagonistic </strong><strong>effects. Emamectin benzoate, novaluron and diflubenzuron </strong><strong>at the two sublethal concentrations reduced average larval </strong><strong>weight, average time to the pupation, %pupation, pupal </strong><strong>mean weight and %adult emergence compared to control. </strong><strong>Results of this study verified the lethal and sublethal </strong><strong>effects of emamectin benzoate, novaluron and </strong><strong>diflubenzuron on the larval stage of S. littoralis, which </strong><strong>negatively affect some biological parameters and insect </strong><strong>population can be negatively affected. Emamectin </strong><strong>benzoate, novaluron and diflubenzuron can be used for S. </strong><strong>littoralis control and in resistance management programs, </strong><strong>because their mode of action is different from pyrethroid, </strong><strong>carbamate and organophosphate insecticides.</strong>

<strong>This research aimed to determine the effect of </strong><strong>processing conditions, including temperature and time of</strong><br /><strong>popping on expansion of popped rice cultivars. The results </strong><strong>of the two seasons 2013 and 2014 showed significant </strong><strong>differences between cultivars for most studied characters.</strong><br /><strong>Giza 178 rice cultivar showed highest significant values for </strong><strong>expansion ratio, weight of popped and popping percentage </strong><strong>in both seasons. Increasing temperature degree from 220 </strong><strong>to 260 oC significantly increased all studied characters in </strong><strong>both seasons. In addition, the optimum time for all studied </strong><strong>characters was 60 seconds. Interaction for expansion ratio </strong><strong>between 40 and 60 second, at 260 oC, revealed a gradual </strong><strong>increase but with different magnitude for each cultivar.</strong>

The aim of current study is to asses the effect </strong><strong>of nitrogen fertilizer types (urea and ureaform) at </strong><strong>different levels on soil organic carbon decomposition.</strong><br /><strong>Soil organic carbon decomposition percentage (SOCD) </strong><strong>is at a minimum amount in the 2nd week and at a</strong><br /><strong>maximum amount in the 7th week at the recommended </strong><strong>urea level - 15% (R-15%). The biweekly SOCD % varied </strong><strong>from 0.82 and 9.55 % at 70 kg N/fed level (R-30%).</strong><br /><strong>SOCD% ranged between 0.16- 12.73, 5.14- 10.61 and 0.41- </strong><strong>8.78% for ureaform level at (R-15%) and (R-30%) less </strong><strong>than the recommended one (R), respectively. The amount </strong><strong>of soil CO2 flux from recommended ureaform level </strong><strong>treatment was the highest one during the entire growing </strong><strong>season. Overall, SOCD% followed the order of R > R-15% </strong><strong>> R-30%. The highest values of SOCD % were 8.4 and 8.2 </strong><strong>at 2.4 Q10 value with urea and at 2.7 Q10 value with </strong><strong>ureaform, respectively. The lowest values of SOCD % </strong><strong>were 2.3 and 4.4 at 2.2 Q10 value with urea or ureaform, </strong><strong>respectively. Soil C: N raties under all treatments were </strong><strong>higher than that of initial state except that under R-30% of </strong><strong>urea. The soil C: N ratio was higher at R-15% of urea than </strong><strong>that when soil treated by ureaform. The opposite trend is </strong><strong>true at R-30%.</strong>

<strong>The neurological damages resulted by abamectin </strong><strong>(ABA) poisoning is not completely elucidated, especially in</strong><br /><strong>cellular organelles such as mitochondria. In the present </strong><strong>study, the pro-oxidant effect of ABA on rat brain</strong><br /><strong>mitochondria was first investigated. A single oral dose of </strong><strong>ABA (3.3mg / Kg body weight; 1/3 LD50) was given to rat </strong><strong>and the brain mitochondria were isolated at various times </strong><strong>(4, 24 and 336 h) after dosing. Oxidative stress in this </strong><strong>organelle was noticed, since it provokes a significant </strong><strong>reduction in the activity of adenosine triphosphatase </strong><strong>(ATPase) and superoxide dismutase (SOD) and reduced </strong><strong>glutathione (GSH) level. In addition, a significant increase </strong><strong>in malondialdehyde (MDA) level was observed in neuronal </strong><strong>mitochondria, indicating clearly an intense peroxidation </strong><strong>within mitochondria. Second, the histochemical evaluation </strong><strong>was carried out to estimate the extent of ischemic brain </strong><strong>injury as a result of ABA exposure. The average area of</strong><br /><strong>infarct for the neurologically impaired rats was increased </strong><strong>in a time-dependent manner. The percentage of surface </strong><strong>area of each infarcted section was found to correlate with </strong><strong>the severity of the neurologic deficit. The results suggest </strong><strong>that ABA-induced neuronal mitochondrial toxicity may be </strong><strong>an important contributing factor to brain aging and </strong><strong>neurodegenerative diseases.</strong>

<strong>This study aims to assess the effect of both of aspect </strong><strong>and slope gradient on some soil characteristics in a</strong><br /><strong>representative watershed in the NW coastal region of </strong><strong>Egypt. Topsoil samples (0 – 25 cm) were collected from</strong><br /><strong>thirty sites approximately evenly distributed over the </strong><strong>entire watershed; depending on a particular combination </strong><strong>of major slope gradient and aspect of soils by using the </strong><strong>spatial analyst function in Arc GIS software. Soil samples </strong><strong>were analyzed for physical, chemical and nutritional </strong><strong>routine characterizations. A factorial model on the basis of </strong><strong>randomized complete block design was used to analyze the </strong><strong>soil data. The results based on statistical analysis showed </strong><strong>significant differences between soil characteristics of </strong><strong>coastal plain (having none of both aspect and gradient) </strong><strong>and those of other different slope aspects and gradient at 5 </strong><strong>% level of confidence. The magnitude of some soil physicochemical </strong><strong>characteristics and available nutrients such as </strong><strong>clay, active calcium carbonate, EC, OM, soil pH, N, P, and </strong><strong>K is significantly higher in the coastal plain soils compared </strong><strong>to northern, eastern and western slope aspect and low, </strong><strong>medium and high slope gradient. However, the available </strong><strong>Fe was significantly higher in the west facing slope and </strong><strong>high slope gradient than the other aspect and slope </strong><strong>gradient. The differences in available nutrients of Mn, Zn </strong><strong>and Cu were not related to slope gradient across soils on</strong><br /><strong>all slope aspects and gradients of the study area. Also, the </strong><strong>results showed that aspect and slope gradient had an effect </strong><strong>on spatial heterogeneity and distribution of some soil </strong><strong>characteristics and nutrients resources in the NW coastal </strong><strong>region of Egypt.</strong>

Effectiveness of substituting sugar (sucrose) with date syrup (Dips) at substitution level ranged Zero , 25, 50, 75 and 100 % toward viability and physical properties of probiotic ice cream containing <em>Lactobacillus acidophilus</em> La-5 and <em>Bifidobacterium lactis</em> Bb-12 were studied during 12 weeks of -18 °C storage period. Viability of <em>L. acidophilus</em> were gradually decreased in all probiotic ice cream treatments during freezing process by the rate of 2.44 log cycle in control sample (34.4% decreasing) and 0.15 log cycle in the sample containing 75% Dips (2.1% decreasing).On the other hand<em>, B. lactis</em> substituted treatments previously referred were affected negatively by the freezing process, by the rate of 0.89, 0.3, 0.55, 0.24 and 0.70 log cycle after freezing process with the decreasing percentage 12.29, 4.64, 7.67, 3.38 and 9.56% compared with control, respectively. The pH values were varied among the substituted treatments after freezing process and during storage period. Overrun property was associated decreasing with the increase of Dips substituted percentage in either of ice cream containing <em>L. acidophilus </em>or<em> B. lactis</em>. Substitution of sugar with Dips caused increasing in specific gravity as well as weight per gallon in both of probiotics ice cream. The melting down of both probiotics ice cream were decreased with the increasing of substitution ratio.The statistical analysis results of sensory evaluation revealed no significant differences between the control sample and the treatment which substituted with 25% in either of probiotics ice cream. Significant affects in flavors were noticed with sugar substitution ratio (50 and 75%), while the treatment fully substituted with date syrup showed no significant difference comparing with control. The present study suggests the possibility to use date syrup (Dips) as a sugar substitute for probiotics ice cream, where retained with an appropriate viable count of probiotics bacteria directly either after processing or during storage, according to the ratio of substitution.

The purpose of this study is to investigate the long-run relationship between real agricultural exports and agricultural economic growth in Egypt using cointegration analysis. Previous studies suggested that these two variables are cointegrated which is considered as evidence of along-run equilibrium relationship. we employed cointegration analysis and annual data for the period 1990-2013 to study the relationship between real agricultural exports and its agricultural production. We found weak evidence of cointegration between real agricultural exports and agricultural economic growth. Results showed that there is a unidirectional causality between output and real agricultural exports. Output causes agricultural exports but not agricultural exports cause its output. On the other hand, Results showed that there is a unidirectional causality between output and Terms of Trade agricultural. Output causes Terms of Trade agricultural but not Terms of Trade agricultural cause its output.

This study aimed to identify the degree of cognitive training needs of the respondents supervisors working in the maintenance of public parks in Riyadh, according to their self-assessment. The study was conducted on 130 supervisor representing 38% of the overall population of all the supervisors working on the seven sites of the city of Riyadh.
Preliminary data were collected through personal interviews using a questionnaire. Data collected were subjected to statistical analysis and presented in the form of: the percentages, arithmetic means, standard deviation, the simple Spearman correlation coefficient, and multiple regression analysis (Stepwise).
Findings of the study revealed that training needs for some 74% of the respondents were low, and 83.1% of respondents were applying their skills and knowledge at a high level. The results of the study also showed a significant negative correlation between the degree of the training requirement (dependent variable) and the independent variables like: scientific specialization and the level of education at the probability level of (0.01).
Also a positive relationship for the nationality of the respondents was found at the same probability level of (0.01). However, significant negative relationships were realized for the independent variables like: place of duty, experience in years, and the information sources at the probability level (0.05). The study exhibited a positive relationship at the same level with the probability for the variables like: place of birth, and the monthly salary.
While no significant relationship has not been established at any of the levels for any of the independent variables like: age, marital status, training. The respondents identified the most important obstacles making their work performance low and offered 13 suggestions to improve their working.
Some 30.8% of the respondents suggest that training programs are needed to increase the working of the supervisors and employees. Whereas about 15.4% of them emphasize the need to adhere to the implementation of programs chalked out for the maintenance work and assignments mentioned.
About 13.8% of the respondents felt the need for the provision of appropriate machinery, equipment and spare parts to undertake their activities better. As little as 1.5% of the total respondents suggested to prepare a comprehensive study to take advantage of the resulting crop of dates of gardens, whether they are good for human consumption or better to convert them to feed. The purpose of the study was to raise the efficiency of the workers/field supervisors involved in the maintenance of public gardens.

This study aimed to identify the level of role caused by the agricultural extension programs radio and television, on the knowledge and skills of Coffee farmers in the Udayn region of Ibb area in the Republic of Yemen. The study also determines the nature of the correlation between the independent variables and the degree of role on the knowledge and skills of the respondents as the dependent variable of those programs.
The study included 200 farmers, representing 86% of the coffee growers of the study area. Preliminary data have been collected through personal interviews using a questionnaire. After the collection of the data, they were subjected to the statistical analyses and were presented in the form of: the percentages, arithmetic means, frequency tables, standard deviation, and the simple Pearson correlation coefficient.
The study revealed that radio and TV Extension programs had low role on the level of knowledge and skills of 46.5% of the respondents, about 44% of them had an average role, and only 9.5% respondents were highly role. The results also showed a positive and significant correlation at a probability level (0.01) between the degree of the level of the role of agricultural extension programs radio and television on the knowledge and skills of coffee growers respondents as the dependent variable: qualifications/ education, the total area of agricultural land, the area under coffee cultivation, satisfaction with the extension service, the degree of exposure to other sources of agricultural information. However, a negative relationship at the same probability level for age and the type of tenure. Also, no significant relationship for the independent variables: the number of family members, main occupation, other agricultural activities, the annual income from the coffee crop, and a full-time agricultural work was found.
The study suggests for the development of the programs that focus on: the need for diversity in agricultural extension programs emphasizing on other agricultural aspects of the production, followed by the establishment of specialized agricultural channel keeping in view the high illiteracy rate and lack of extension services in the region. Farmers want that agricultural programs should be recorded in their fields to ensure their credibility. The study revealed that farmers ask for the re-broadcasting television programs on what’s good for their lands and also through Satellite Channel once a week due to repeated power shut-off in most of the rural areas in Yemen.

The study aimed at analyzing the role of accounting data and information in the decision-making process of grain-public companies companies in Egypt. The case study examined is the General Company for Silos and Storage. Both of the statistical and financial analyses have been used. These analyses are confined to two main sections; the first dealt with the Company’s activities pertaining to imported wheat. The second handled the role of data and information in making the Company’s decisions.
The study results of the first section disclosed the following: (1) Amounts of wheats imported in 2013/2014 outweighed those imported in 2012/2013 by 32.97%. (2) The main wheat-importing countries of Romania, Russia, and France realized imported-amounts’ increases of 52.97%, 118.47%, and 91.52%, respectively. Whilst both of the USA and the Ukraine have experienced imported-amounts’ decline of 78.12% and 52.64%, respectively. (3) Wheat imports reaching the ports of Damietta and Alexandria have witnessed wheat-imports’ increases of 68.03% and 56.85%, respectively. Whereas the port of El-Dekhaila has practiced a decline of 20.77% in wheat imports. The port of Safaga has witnessed no change whatsoever.
The second section, which is typical to the case study examined during the period 2008/2009- 2012/2013, showed the following: (1) Employment rates in the Company have declined significantly despite of offering high wage rates. This is partially because wages occupied a large portion of the Company’s cost structure with ratio of wages to returns of 37.61% in the 2012/2013 budget. (2) The Company suffered from inventory-stock accumulation which is estimated at 6.42% of the current liabilities. Moreover, capital accumulation is found to be poor with a net fixed-assets ratio of barely 17% during the average study period. (3) Weak and poor liquidity ratios and self-financing sources are common trajectories in the Company. And (4) depressed sales and collection policies, as indicated to by the ratio of cash to returns of 0.31 during the average study period.
The existing financial and crediting records of the General Company of Silos and Storage indicated to numerous imbalances and shortcomings. These inadequacies could be corrected via the acquiring, implementation, and analysis of upright data bases.
Finally, the study recommends the application of regular financial and statistical analyses of data and accounting information of the company to identify aspects of strengths and weaknesses. Consequently, better decision making and policy formation could be made in accordance with governmental policies.

The research aims at studying the relation between knowledge resource and the bread winner's ability to take family decisions through two pivots for managing knowledge resources, represented in the sources of getting knowledge and the requirements of knowledge management. In addition to studying his ability to take the family decisions in its dimensions like determining the problem, specifying the available alternatives, choosing the appropriate alternatives, carrying out the alternatives and assessing the results. It also aims at studying the relation between some study variables and the bread winner's management of the knowledge resource and taking the family decisions. Also, the study focuses on the difference amongst the female bread winners "study sample" in managing knowledge and taking the family decisions according to their educational level, and determining the aspects of difference amongst the rural and urban female bread winners (employed and unemployed ones) in each of managing knowledge and taking decision.
The study sample included (304) female bread winners (employed and unemployed in rural and urban areas) in Dosok and Mansura towns and some villages following them in Kafr Ash-Shiekh and Dakahlia governorates. The sample had been chosen by random from various social and economic levels. The study tools included a form of public data and knowledge management and decision taking questionnaires.
The most important results there is correlation relationship between resource management in its two aspects and taking the family decisions in its five dimensions by the bread winner. There is also correlation relationship between knowledge resource management and the bread winner's taking decisions and some variables in the social and economic levels. There is no difference amongst the average degrees scored by all female bread winners- in rural and urban areas- in the management of knowledge resource. There are also differences amongst the average degrees scored by all female bread winners- in rural and urban areas- in taking decisions and the high scores were for the rural female bread winners. Difference in the average degrees scored in the management of knowledge resource amongst the employed and unemployed female bread winners for the employed e female bread winners. No differences in the average degrees of all employed and unemployed female bread winners concerning taking the decisions. There is no statistical indicative contrast amongst the female bread winners (study sample) in knowledge management and taking decisions according to the educational level. There is a statistical indicative contrast amongst the female bread winners (study sample) in the sources of getting knowledge according to the period of the female bread winner's marriage where the value "f" is 0.69 and an indicative value at "0.001 indication. By applying Tukey test, it became clear that the scores average of the female bread winners (study sample) in this dimension vary between (27.42) represented in short marriage period (less than 5 years) to (29.30) represented in a marriage period that more than 10 years and the high scores were for those having long period of marriage. There is no statistical indicator amongst the female bread winners (study sample) in the total number of taking decisions according to the period of the bread winner's marriage, where F value reached (3.15), it is non-indicative statistically.
The study recommendations: The necessity of the government's adopting the culture of knowledge management and participating in it by establishing an organizational environment basing on the participation by knowledge and personal experiences. The media shall put programs for the development of the bread winner's awareness concerning knowing the importance of the knowledge resource and how to manage it for helping in solving its problems for taking the sound decision in the appropriate time. The mass media shall adopt an idea for knowledge management as a means for the development and improvement of the individual and collective performance inside the institutions of the community in general and the institutions of family and childhood in particular. The government and mass media shall prepare a definite and clear strategic plan for managing the knowledge to specify what you want to achieve.They also shall improve the investment of the information and knowledge the individuals of the society have as a whole and to make them valuable through participation and accepting their opinions.The government shall design and provide databases for keeping all what is collected of information and data in all fields.
