The recent study aims to identify the Impact of Domestique culture variations on the degree of political participation for rural women at two different sub-cultures in rural Egypt. In addition identify factors affecting the degree of rural women participation in political issues. In order to accomplish the study objectives, Qalubiya Governorate was selected to represent the culture of Lower-Egypt Governorates, and Minia Governorate was selected to represent the culture of Upper-Egypt Governorates. Each Governorate,s administrative districts were divided into three categories (High, Medium, Low) based upon their human development indices, related to status of woman at those communities. Two districts were selected randomly from the medium category of the common human development index, Banha district from Qalubiya Governorate, and Maghagha district from Minia Governorate. From each of those districts two local village units were randomly selected. Within each of those previously mentioned villages, a random sample of 160 rural women was selected, and the total sample was 640 rural women. A questionnaire was designed and collected using the personal interview (after it was pre-tested) during August, September, and October 2003, then the data were tabulated and analyzed by using X2 coefficient. The study findings showed that about 43% of the total sample have low level of political participation, medium category represents about 28%, and high category of the political participation

The agricultural policy in Egypt showed great importance for improving organic agriculture technology to produce clean and safe crops and foods. This will have positive economic and environmental response on human beings, animals, plants and soils. The present study aimed to clarify success opportunities for cultivating cotton, summer potatoes and wormwood under organic system in Egypt. The study made also a comparison between organic and chemical agriculture in sandy soils, by testing investment efficiency for organic agriculture in the sandy soils. The study states that total area of organic agriculture was about 26.3 thousand feddan in 2003, and this area is increasing at about 1941 feddan a year. These areas expected to be nearly 35 thousand feddan in year 2010. The economic production that realize the economic efficiency could not be obtained at least before 5-7 years to gain complete use from adding organic matter to sandy soil. The preference of organic agriculture over chemical agriculture is due to its advantage in enhancing mechanical soil properties and avoiding chemical pollution of agriculture. Another advantage of organic agriculture is to keep environmental balance of living organisms in soil and enhancing vertical agricultural increase in sandy soils to add indirectly new agriculture area to present agricultural land. The two criteria used in the study; net cash flow and cost/ benefit ratio indicated the advantage of organic agriculture over chemical agriculture for cotton, potatoes and wormwood crops. Meanwhile, the internal rate of return in case of chemical cropping was higher than that of organic agriculture for cotton and summer potatoes. This may be due to the great loss of nutrient elements occurred by leakage, and thus decreasing total benefit from adding organic matter in the first years of organic agriculture. The increase of the internal rate of return of the two crops organically cultivated in the sandy soils is an indicator for its economic

A sample of wheat grain var. Research-32, cultivated locally in the Republic of Yemen was treated and milled into flour of 72% extraction.  Main chemical components of the flour were determined, then the flour was portioned out to three sets.  Each set was made into dough with similar constituents except the type of fat, where Al-Kamaria ghee, Al-Mumtaz butter and Crude sesame oil were added to the first, the second and the third sets respectively. Three samples of each set with levels of 15, 25 and 35 % were prepared.  Rheological properties of the dough were tested and compared with those of dough samples made of SNABLE wheat flour, which were prepared and treated under similar conditions.  Physical and organoleptic characteristics of cookies made of both Research-32 and SNABLE flours were evaluated also.  Results indicated that concentrations of total protein and wet gluten in Research 32 wheat flour were found to be significantly (0.05=α) higher than those of SNABEL flour.  Though of their high values of water absorption and degree of stability, Research 32 dough samples were characterized with moderately low calculated proportional number, which indicates the suitability of Research 32 wheat flour for use in making cookies of good quality.  Statistical analyses of data obtained through testing physical and organoleptic properties of cookies made of Research 32 dough mix with 35% fat showed that cookies were found to be of high and acceptable quality among Yemeni consumers at 0.05 level of significance.

Laboratory experiments were carried out to investigate the effect of two bacterial commercial products of B. thuringiensis (Dipel 2x and Protecto) on eggs and the newly hatched larvae of pink bollworm, P.gossypiella. Different concentrations of both commercial products of B. thuringiensis were tested. The results showed that the percentage of larval mortality increased by increasing concentration and the period after treatment, calculated LC50s values after 3-7 days of treatment. Treatment of eggs did not affect, significantly, the hatchability. While the percentage mortality of newly hatched larvae produced from the treated eggs was high according to the concentrations used.

The work was conducted to clarify the efficiency of certain insecticides on the population of whitefly B. tabaci and incidence of yellow leaf curl virus (TYLCV) in tomato field. The experiment was carried out during Nili plantation of two successive seasons at El-Fayoum governorate. The obtained data showed that the alternate use of etofenprox /thiamethoxam; imidacloprid/ thiamethoxam; acetamiprid/ etofenprox; single continuous application of etofenprox; etofenprox / imidacloprid; acetamiprid/ imidacloprid; thiamethoxam/ acetamiprid; imidacloprid; thiamethoxam and acetamiprid gave excellent initial mortality over 90% on the adult stage of B. tabaci and incidence of tomato yellow leaf curl virus without significant differences between treatments. Thimethoxam as soil drench proved to be the most effective insecticide against adult and immature stages of whitefly, while acetamiprid achieved the lowest mortality for these two stages as well as short residual mortality. On the other hand, alternation of etofenprox / imidacloprid showed the highest initial mortality on nymphs. Residue levels in tomato fruits were also investigated at 30, 45 and 60 days after application of tested insecticides. For imidacloprid residues were found in amounts nearly above maximum residue levels MRLs 30 days while degraded to amounts below MRL by the progression of time to 45 and 60 days after application. Application of imidacloprid in alternate spray program with thiamethoxam; etofenprox; acetamiprid resulted in residues below MRL at the 3 preharvest intervals. Acetamiprid when used at the recommended rate showed the residue of 0.36 mg/kg at early season and then decreased to 0.08 mg/kg at late season. Alternate use of acetamiprid with thiamethoxam; etofenprox or imidacloprid reduce MRLs in tomato fruits. The successive applications of etofenprox alone at the recommended rate resulted in residues above MRL after 30 and 45 days and approximately near MRL at 60 days. On the other hand, the half rate in alternative use with imidacloprid; acetamiprid or thiamethoxam showed residues below MRL at all sampling intervals. Thiamethoxam when used in single successive applications gave residues of 2.5, 1.9 and 1.5 mg/kg at the 3 preharvest intervals, respectively

Two field trials were carried out at South Tahrir Research Station (Ali- Moubark). These trials were conducted in 2003 and 2004 to evaluate three planting dates of maize (the over story shade crop) intercropped with groundnut i.e, on 1st June, 10th June and 20th June, and four plant densities of maize intercropped with groundnut, i.e, maize was spaced at 50 and 100 cm apart leaving one or two plants/hill. Groundnut (the main crop) was grown on all rows. The data obtained indicate that ear length, ear diameter, number of rows/ear, number of kernels/row and the weight of 100grains increased with increasing maize spacing as well as with diminishing the number of plants remained per hill after thinning (to one plant/ hill). On other hand dense planting resulted in higher yield of maize whether by narrowing maize spacing or increasing the number of maize plants per hill after thinning. Yield and yield components of maize were significantly decreased by delaying planting date of maize up to the latest date. Yield /fed and yield components of groundnut were associated with maize density and distribution. The more the shade offered by maize the less the values of these traits were obtained. Highest values were obtained when maize was spaced at 100cm. and thinned to one plant/ hill. Increases in the values of yield and yield components of groundnut were associated with delaying the planting date of maize. Delaying the planting date of maize resulted in increases in the values of land equivalent ratio (LER) and the relative crowding coefficient. The treatment effect at any planting date of maize exerted very low competitive pressure when aggressivity was measured. With delaying seeding maize, competitive ratio (CR) diminished to the least. Spacing maize at 50cm. apart and leaving two plants / hill after thinning resulted in highest value of LER and relative crowding coefficient (RCC). Nor any maize density had any heavy competitive pressure on groundnut when aggressivity was measured

Different types of whey proteins concentrate (WPC) were prepared in Brewaster Dairy pilot plant at Ohio State Univ. USA and used for formulating an infant formula and compared with Alacen 841 (Commercial WPC) as control to select the best WPC preparations which succeed in manufacture of infant formula. Infant formula was prepared with different types of WPC (Alacen 841, UF 5x, UF4x, DF 8x and DF 4x). The ratio of WPC: sodium caseinate was 40: 60. Salt, sucrose, lecithin and vegetable oil were added then homogenized and sterilized after sealing at 121ºC for 6 minute, cooled in an ice bath and stored at room temperature. Samples were analyzed chemically and organoleptically when fresh and after storage at room temperature for three months. Emulsion volume index (EVI), viscosity, protein solubility, sedimentation and particle size were determined before and after sterilization. Results showed that EVI, viscosity, sedimentation and particle size increased after sterilization than before where as protein solubility take an opposite trend. Emulsion volume index, viscosity, sedimentation and particle sizes were increased after storage at room temperature for three months than fresh. Whereas proteins solubility deceased after storage than fresh. Statistical analysis showed high significant difference (α0.05) for emulsion volume index, protein solubility, viscosity, particle size and sedimentation.

Phytostimulation microorganisms (PSM) viz. Trichoderma harzianum (TH), Bacillus subtilis (BS) and arbuscular mycorrhizal (AM) fungi were tested individually or in mixed culture for their ability to induce pathogenesis-related (PR)-proteins (chitinase, β-1,3-glucanase, peroxidase, phenylalanine ammonia-lyase PAL) and phenolics in tomato plants grown in sterilized soilless medium artificially infested with or without the Fusarium oxysporum f. sp. radicis-lycopersici (FORT). PSM-treated plants were more developed than non-treated control or inoculation with FORT. PSM-treated plants were effective in reducing diseases produced by FORT infection. Plants application with PSM significantly increased the activity of peroxidase, chitinase, β-1, 3-glucanase and PAL and accumulated phenolics in tomato plants compared to untreated control. Among the treatments, AM fungi recorded the maximum increase in the activities of all defense–related enzymes and accumulated phenolics followed by T. harzianum and B subttilis. The maximum increase in the activities of peroxidase, β-1, 3- glucanase, PAL and accumulated phenolics were observed 6 days after application of PSM. However, the maximum increase in the activities of chitinase was observed 9 days after application of PSM. Several fold increase in the accumulation of phenolics and activities of defense enzymes was observed when the induced plants were inoculated with Fusarium oxysporum f. sp. radicis-lycopersici (FORT). These results suggest that enhanced activities of defense enzymes and elevated content of phenolics by inoculation with PSM may contribute to protection of tomato plants against F. oxysporum.

A study on mite species in marjoram and chamomile plantations in Fayoum was carried out during 2003 and 2004 seasons. Twenty-six species were found and divided according to their feeding habits into three major groups, phytophagous (7 species), predaceous (8 species) and a group of debatable feeding habits (11 species). Population density evaluation showed that Tetranychus urticae Koch was the main phytophagous mite on both hosts. The predatory mite Amblyseius cydnodactylon Shehata and Zaher was dominant on marjoram followed by Hemicheyletia bakeri (Ehara). From the debatable group, Pronematus ubiquitus Mc Gregor was the dominant followed by Tyrophagus putrescentiae (Schrank) and Paralorryia gizai El-Bagoury. On chamomile, the predatory mite Eupodes niloticus Abou-Awad & El-Bagoury was dominant and from the debatable group, Tydeus kochi Oud. was dominant followed by T. putrescentiae and P. gizai. Population densities were insignificantly affected by temperature and relative humidity.

Bacterial canker caused by Clavibacter michiganensis subsp. michiganensis (Smith) and bacterial spot caused by Xanthomonas campestris pv. vesicatoria (Doidge) Dye have become important diseases of tomato in Egypt. The present work was planned to evaluate the reaction of different tomato cultivars and the role of seeds to transmit both pathogens. Cultivars of Dora, Flora-Dade, KTM141, Money Maker, Niagra, Super strain B hybrid and GS12 were moderately resistant to both diseases, but Castle rock, Peto 86 and Super strain B cultivars were susceptible. However, Castle rock, Peto 86, Super strain B and Niagra cultivars were highly susceptible for bacterial canker than spot disease. Using the Liquid assay method, C. michiganensis subsp. michiganensis bacterium could be detected in seeds of cultivars Dora, KTM141, Niagra and Super strain B hybrid, but X. campestris pv. vesicatoria was detected on seeds of cultivars GS12, Peto 86 and Super Marmand. However, both bacterial pathogens were not detected in seeds of all cultivars, except GS12, when direct planting method on selective media was used. In an in vivo assay, bacterial canker has developed more than bacterial spot disease on tomato seedlings produced from non-treated seeds. Bacterial canker has developed on all tested cultivars at different frequencies. Transmission of both pathogens occurred at high frequency by seeds of cultivars Niagra and Dora, however bacterial spot was not borne on samples of other tomato cultivars
