AL-ali A. | B. Issa | S. Lawand
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.

Egypt depends on the Nile River as a major source of water, it provides about 76.3% of its water requirements, other water sources provides about 23.7% of total water requirements. Agriculture sector is the main consumer of water in Egypt as it consumed about 85.9% of the total actual consumption of water in 2009. The main problem of the present paper is the decrease in the efficiency of water use in Egyptian agriculture. The objective of paper is to assess the efficiency of water use in agriculture in the old and new land Egypt through the use of partial efficiency measures. Results showed that in average of the cost of irrigation per feddan during the period (1998-2009), that was for winter crops in the old lands as follows: 85.3, 105.8, 119.3, 127.3 pounds/feddan for faba bean, sugar beet, alfalfa sustained, wheat at a cost of irrigation per feddan of which respectively. For summer crops in old land cost was about 114.7, 129.5, 139.8, 156.2, 217.8, 606.1 pounds/ feddan at a cost of, sesame, soybean, peanut, corn, rice, sugar cane, respectively. For the winter crops in the new lands irrigation cost per feddan was about L.E 99.3, 169.0 for garlic and onion respectively. Summer crops in the new lands irrigation costs for watermelon, cucumber, potatoes, eggplant, peppers, and tomatoes were as follows: L.E 92.4, 133, 138.7, 139.8, 157.7, 194.3 pounds/ feddan respectively. The results of the statistical analysis of partial-efficiency measures showed that, according to the criterion of net revenue from the water unit - winter crops on the old land as follows: alfalfa, wheat, faba bean, and sugar beet. As for the summer crops of old land the results showed of the statistical estimate of the partial-efficiency measures that peanuts, corn, sesame, sugar cane, rice, soybeans respectively. In the new lands the results of statistical analysis for the partial- efficiency measures, according to the standard net return of the water unit for winter crops were garlic followed by the first crop of onions. As for the summer crops, the results of statistical analysis of partial -efficiency measures, according to the standard net return of the water unit came summer crops in the new lands, were as follows: potatoes, tomatoes, watermelon, cucumber, eggplant, pepper. The results in general indicated the necessaries of reconsidering the present structure of cropping pattern to increase the efficiency of irrigation water use.

The research aims at studying the indicators of Adoption (Rate of Adoption and Degree of Adoption) of sprinkler irrigation technique of farmers growing wheat depend on underground water for irrigation (wells) and studying some of the economical and social factors and others which influence the decision of the wheat farmers in adopting sprinkler irrigation technique and knowing the obstacles which limit adoption of this technique. To fulfill aims of the research, the data were collected from a random sample, (335) farmers from the two zones, the first and second agricultural stability zones from the north region (two provinces of Aleppo & Idlep) by an interview questionnaire in the third and fourth quarters of 2010. The study relied on the following tests and measures: Correlation, binary logistic regression . Results of the research have shown that the farmers adoption rate of sprinkler irrigation technique was 47.8% and the adoption degree of this technique is 50.9%, and the adoption rate of this technique is expected to increase from 47.8% in 2007 to77 % in 2030 with an annual rate of nearly 1.27. The results of studying the factors which influence the adoption of this technique using binary logistic regression revealed a negative significant relation between the dependent variable " adoption of modern irrigation techniques by wheat farmers" and all the independent variables (Percentage of farming labor force to total family labor force, the availability of labor force, the availability of water for irrigation). While, there has been revealed a positive significant relation between the dependant variable (sprinkler irrigation technique adoption by farmers) and all independent variables (crop area, family participation in agricultural decision making, attitude of the farmer towards the agricultural extension, the percentage of farmers with level of elementary certificate and above). The results also have shown that the factors which influence the decision of wheat farmers adoption of sprinkler irrigation technique varies between the first agricultural stability zone and the second one concerning the effect value and its signification. The results have shown that the great obstacles which limit the sprinkler irrigation adoption was increasing the technique cost of 38.1 % and the ignorance of the loans& facilities which are presented by the transfer project to the modern irrigation in a percentage of 14.2 %.

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 research aimed to identify the training needs for agricultural officials in the control of sunn pest affecting wheat in general, and to identify the correlation between training needs and the independent variables surveyed, namely (age, educational level, gender, managerial position and a number of years of service), and to order the items of training needs according to the needs of agricultural officials. The search included all agricultural personnel in Nineveh province, (172) employees, where a simple random sample of them represented by 40% with a rate of (69) employees, were takes. A questionnaire consisting of two parts, was designed. The first part included a number of questions to obtain personal and vocational information for agricultural officials, while the second part included scale to measure the training needs, which included (32) items relating to the training needs, for control of sunn pest affecting the yield of wheat. The questionnaire was offered to the specialists in agricultural extension and in education, to make sure face validity and was also offered to specialists in the plant protection to ensure the content validity for items of the scale. The reliability of the scale was found in siplit-half method. Data was collected during December, 2010.

The study amid to investigate the stability of production and Egyptian exports of onion and analysis of production policy of the crop. This is to show the economic effects of taxation and the support of the crop on the production and the comparative advantage of the crop to redistribute the Egyptian exports of onions so as to increase the value of exports of the crop. The results of the analysis indicate that values of nominal protection coefficient of Tradable output, nominal protection coefficient of Tradable input were, 0.90, 0.93 and 0.90 in 2010 year, respectively indicating that producers did not obtain the real prices of their production which turned to the form of support to the consumer. On the other side, theDomestic Resource cost was 0.20 in the year of 2010 indicating the comparative advantage in the onion production. Results of stepwise multiple regression of the factors affecting the Egyptian exports showed that feddan productivity, the farm price and export price of U.S onion have statistical significant effect on the quantity of exports with F value being 17.82 the above factors contribute at 86% of the total factors affecting the onion exports during the study period (1995-2010). The results of linear programming showed that a minimum limit of Egyptian exports of onion to the importing countries, is necessary so as to the Egyptian exports of onion do not lose any foreign markets which, in turn, increase the value of onion exports by 44.64% compared to the current value in order to take advantage of importing the promising markets of onion crop, such as Saudi Arabia, Iraq, Jordan, the Netherlands and Italy.
