This investigation was conducted at Hada Elsham Experimental Research Station, King AbdulAziz University during 2007/2008 and 2008/2009 seasons, to study the effects of two irrigation water salinity levels (1200 mg/L and 10000 mg/L), three irrigation water intervals (3, 6 and 9 days) and three sulphur fertilizer rates (0.0, 4.0 and 6.0 t/ha) on seed yield; yield components and seed quality of canola, Pactole cv. The obtained results showed that seed yield kg/ha was significantly increased (Received June 1, 2009) (Accepted June 27, 2009) under the 1200mg/L irrigation water and 6t/ha of sulphur more than the seed yield/ha under the effect of 1200 mg/L irrigation water with 4 t/ha sulphur or 10,000 mg/L irrigation water with 6t/ha sulphur with no significant differences between the two later treatments. Irrigation every 3 days significantly dominated over the irrigation every 6 or 9 days on seed yield and yield components. Irrigation with 10.000 mg/L salinity water significantly decreased No. of branches /plant, No. of fruit/plant and seed weight/ plant. Besides, Protein content of the seed as well as oil content increased as water salinity increased in both seasons. As sulphur fertilizer rate increased seed yield, yield components protein and oil contents of seed significantly increased, in the two studied seasons.

Study was conducted during 2008 - 2009 on five local grape cultivars: Gubery, Assemy, Aswed, Razeql and Bayadh at the faculty of AgricultureThamar University . Cultivars were collected from Rawdha and Bany Husheish area - Sana'a Governorate. Morphological and physical characters of berry were determined and the chemical analysis for juice was also assessed. Finally, cuttings were taken from all, cultivars and cultivated at the nurser.Data were collected and analyzed by SAS system according to the least significant difference at the probability level of 0.05 and the results showed that: Assemy cultivar gave the maximum value of berry weight of 8.5 g, whereas the lowest rate was for Razeqi cv. of 1.2 g. According to berry dimensions, berry length ranged between 1.6 - 2.6 cm and berry width 1.35-2.43 cm. Razeql cv. gave the highest content of T.S.S (24.5%), whereas Gubery cv. contained the lowest value of 20.37%. pH value was between 3.98-4.77 and organic acids were between 0.35 -0.80%. Aswed cv. gave the highest rate of rooting percentage of 58% meanwhile, the lowest rate was found In the Razeqi cv. (6.75).

Where China, United States of America and India in the front of producing countries and was the relative importance of the Egyptian production of cotton for the world in tenth place. The harvested area it may an annual average of about 33.205 million hectares during the same period. Where India, United States of America and China in the front of those countries, while the average quantity of world exports during the same period was estimated at 8.293 million tons / year. Where United States of America, Uzbekistan and India in the front of those countries, were ranked Egypt in the ninth position. while the imports it may average annual rate during the same period was estimated at 7.76 million tons / year. Where China, Turkey and Indonesia in the front of those countries, The world Stock comes China United States of America and India in the front of those countries during the same period, while the consumption of cotton, it may average annual rate during the same period was estimated at 21.15 million tons / year. Where China, India and Pakistan in the front of those countries. There is also a decrease in the area of the Extra long staple cotton in Egypt by 6040 feddan per year during the period (1990-2008). The area of long-staple cotton, there is a decrease up to 18190 feddan annually during the same period, while the production of Extra long staple cotton there are decline 6620 tons annually, while the production of long staple cotton there is a decline of 13,250 tons annually during the same period. With regard to the evolution of the total production costs of cotton in Egypt, there are increasing by 113.14 pounds / feddan per year as well as prices of farm cotton in Egypt, there are increasing by 170.95 pounds / tc5ns every year either total return for Egyptian cotton, there is increased total 173.34 pounds / feddan per year during the same period, The net return of cotton feddan to the study, noted the relative stability, and that it ranges around the arithmetic mean during the study period. Looks at the future of cotton in the world by forecasting its progress during the period (2009-2018), the direction of the Beginning stock to decline during the same period, while that the harvested area and end stock consumption relatively stable during the same Period, while exports and imports tended to increase during the same period, As for the forecasting of the Egyptian market during the same period the harvested area has tended to decline while increasing domestic consumption and with the relative stability in the beginning stock, as well as exports, Comparing the results to predict the global and Egyptian variables is showed Egyptian market for cotton towards the import of foreign cotton.

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.

The almond seed wasp Eurytoma amygdali Enderlein (Eurytoma amygdale End) is an important insect on almonds Amygdalus sp in its plantig regions, causing a large loss in the production. The relationship between the adults of almond seed wasp in five regions: mid Syria (Homs), Southern region (Al Qunaitera, Swedaa), and the countryside of Damascus (Beet Tema,, Deer Ateah) was studied by ISSR. The results indicated that the females from Homs formed a separated cluster, and the females from Beet Tema and Deer Ateah were the most closed to each other,also the female from Al Qunaitera and Swedaa were closed to each other. It was noted that the males separated into two clusters, the first one contained the males from Homs and Swedaa, and the second contained the males from Beet Tema, Al Qunaitera and Deer Ateah.
