This study explored the opinions of central level extension employees about whether the Egyptian agricultural extension system needs to be reformed or not, and the alternatives they consider to be the best-fit options for extension in Egypt. The study covered 98 extension employees at the central level; findings show that all aspects of the Egyptian extension system are good candidates for reform and possible restructuring. These aspects could be ranked as financing, policy & organizational structure, staffing, and field operations as reported by 100%, 95%, 91%, and 68% of the respondents, respectively. Concerning the overall extension system, about 91% of the respondents reported that the Egyptian extension system is a good candidate for reform and possible restructuring. Findings also show that devolution, deconcentration, and delegation were the appropriate arrangements for extension decentralization as mentioned by 85%, 82%, and 55% of the respondents, respectively. Moreover, alternatives of providing and financing extension services were suggested and prioritized.

Mountain goat in Syria is one of important domestic animals, because its characters can produce and reproduce under the hard environmental conditions, it was used in crossbreeding with Syrian goat as a donor to acclimatization and resistance of diseases traits. In spite of that, this animal is still faraway from the scientific search, Moreover, it was exposed to random crossbreeding with Shami Goat by goat breeders, of which will lead in a long time to loss an important domestic animal genetic source, some of it,s characterizes were not detected. In this search, the genetic diversity among samples of pure mountain goat that exist in Era Station Search in AL-Sowidaa by using (SNP-PCR) was studied. The results indicated that this technique is successful for defining the genetic similarity and variance among samples of goats that under study, Moreover, the locations of some important genes were discovered, and that will help us in starting of genetic mapping for this economic animal.

Wheat is the most important strategic crops in Syria because it supports the national economy and provides a loaf of bread. The evaluation of wheat validity or its suitability for the bread production as well as the quality of the resulted bread, depends on its flour characterizations and character of formed dough as well as on quality of the resulted bread. Three water treatments were applied as follows: 500, 400, 300 ml on seven varieties and five promising lines of bread wheat selected at ICARDA. After the harvest and getting the productivity, the protein and Farinograph test were assessed. Response of varieties and lines differed, depending on the water treatments. Also in the same water treatment the productivity varied among them clearly, but not associated with any of the studied technological indicators. A correlation relation between the percentage of protein and the irrigation rate, as well as between the Farinograph development time (FDT) and Farinograph Mixing Tolerance (FMT), was observed. Quality of the dough varied according to studied plant material and also by applied water treatment. Plant material studied was divided into four groups: two groups of them characterized weak dough to medium strength which were suitable for the Arabic bread, and other two characterized by strong dough to very strong which, were more suitable for French bread.

This study aimed to establishing a protocol for producing in-vitro plants of Rosa Damascene. The culture was conducted at the Commission of Biotechnology in Damascus. Four types of explants were cultured on MS medium and some factors affecting culture were examined. The results showed that no viruses were observed, the lateral buds were superior over other explants, then the lateral microcuttings, after that, the apical micro-cuttings, and, finally, the shoot tips. The highest multiplication rate was observed at the hormonal combinations of (benzyl adenine BA 3mg/l with indole-3-acetic acid  IAA 0.1 mg/l), and the highest elongation average were observed at ( IAA 0.1 mg/l with BA 2-6mg/l) or ( indole-3-butyric acid (IBA) 0.1 with (BA) 5-6 mg/l). The transferring was positively effective. The highest rooting percentage was observed when naphthalene acetic acid NAA or IBA were used. (Berlite: peatmoss, 1:1) was the best growing medium for hardening.

A greenhouse pot experiment was carried out to investigate the effect of salinity and potassium at different levels alone or in various combinations on growth, mineral and proline content in leaves of plantlets of Phoenix dactylifera L. cv. Bartomouda (in vitro production, two years old from acclimatized them). The following treatments were applied: three levels of salinity Na Cl + Ca Cl2 w.w 2:1 (14000, 16000 and 18000 ppm.) and two levels of potassium (2000 and 3000 ppm) in addition to control (no salts or potassium used), salts and potassium were added in the irrigation water. In general, all levels of salinity significantly decreased various growth parameters such as plant height, number of leaves and roots, root length, fresh and dry weights of leaves than that of the control. These parameters were decreased with increasing salinity levels, whereas it, significantly increased Na, Ca and K contents in leaves with high content of proline. The treatment 18000 ppm salts gave the highest significant reduction of the growth parameters, while caused an increase in proline Na, Ca, and K contents compared to control treatment (no salts) . This was true in both seasons. The applications of potassium significantly increased the previous growth parameters as compared with the control treatment (without salts and potassium) the treatment 3000 ppm had the highest results. Moreover the applications of potassium gave high alleviated the negative effects of salt stress, the treatment 3000 ppm gave the best results on the growth parameters of date palm plantlets grown under salinity condition . Regarding the interaction the obtained data revealed that the interaction between treatment 3000 ppm potassium and 14000 salts produced the highest significant results. Generally, from the obtained results it can conclude that the plantlets of date palm produced by tissue culture can be tolerated salt stress by addition of potassium which can significantly ameliorate the harmful effects of salts, positive effects on the growth parameters of the plantlets was showed by potassium applications.

Two successive field experiments during two seasons of 2008 and 2009, were carried out to evaluate some safety treatments including: mulching, tunnels, natural yeast extract, antioxidant and two rhizobacteria Serratia marcescens and Pseudomonas fluorescens towards root-knot nematode Meloidogyne spp. on strawberry plant grown in naturally infested soil and consequently their probable effects on growth parameters, chemical components and yield of strawberry compared to untreated control. Results of this study confirmed that all used treatments, significantly reduced all related nematode parameters i.e. number of galls/root system; number of egg masses/root system as well as number of juveniles/250 g soil ﴾either after 2 or 4 months﴿ when compared to plants grown in the naturally infested soil only. The highest percentage of reduction in all related nematode parameters were noticed after 4 months. Mulching, S. marcescens, P. fluorescens and tunnels, played an important role in reducing the percentage of nematode parameters. Mulching and S. marcescens reduced the percentage of gall numbers/root system by 77%, followed by tunnels by 75% and P. fluorescens by 70%. S. marcescens reduced the percentage of egg masses/root system by 80% followed by P. fluorescens by 78% and mulching by 76%. Results indicated that the soil treated with mulching, also significantly reduced the percentage of juvenile numbers/250 g soil by 79% followed by S. marcescens by 73%. Results confirmed also that all used treatments significantly increased all related plant growth characters viz. leaves, stems, root fresh and dry weight; plant height, leaves number, root length as well as false stem length. Moreover, these treatments significantly increased the activity of some oxidative enzymes e.g. peroxidase and phenoloxidase as well as some other chemical components i.e. total soluble solids (T.S.S %) and vitamin C (V.C). Results revealed that all previous treatments significantly increased the early and total yield. Our results confirmed that, the rhizobacterium S. marcescens came in the first rank as a promoter of all related plant growth characters, followed by tunnels and mulching treatments. Results confirmed that also the antioxidants, are considered the effective one in enhancing the activities of peroxidase and phenoloxidase as well as T.S.S% and V.C followed by the natural yeast extract

The phytochemical studies on Zingiber officinale rhizomes revealed that it contains traces of flavonoid, carbohydrates, tannins, steroles or terpenoids and it is free from alkaloids.Assay of essential oil of Zingiber officinale rhizome was also carried out. The alcoholic extract of the plant rhizome, was examined against five tumor cell lines, BHK-2, HEPG-2, MCF-7, HCT-2 and HEP-2, using SRB. assay. All cell lines were growth inhibited in a dose dependent manner after exposure to the plant extract. The antitumor activity of the plant extract using E.A.C. method, showed a high activity against mice tumor.

The recent study aims to: identify the degree of farmers implementations for the recommendations of the technical rationalization of water use in New valley Governorate. In addition, identifying the independent variables affecting the degree of farmers implementations for the recommendations of the technical rationalization of water use as a dependent variable. In order to accomplish the study objectives, new valley Governorate was selected as a filed study. A systematic random sample of 212 farmers was selected. This sample represents about 5% of the total farmers in three villages in New valley Governorate. A questionnaire was designed and collected using the personal interview (after it was pre tested) during may 2011. Then, the data were tabulated and analyzed by using simple correlation coefficient, stepwise regression. The study finding showed that about 14% of the total sample have low level of implementations for the recommendations of the technical rationalization of water use. Medium category represents about 50%, and high category of implementations for the recommendations of the technical rationalization of water use represents about 36% of the total sample. Results revealed by using stepwise regression showed that three variables affected the degree of implementations for the recommendations of the technical rationalizations of water use, and these variables explained about 51% of the total variance of the implementations for the recommendations of the technical rationalization of water use. Those variables were: farmland holding size, respondent attitude towards the extension activities, finally respondent degree of formal social participation.
