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).

The aim of this study was to use spreadsheet software (Excel) to solve linear programming models in formulating least cost rations of egg layers. The Ingredients used are corn, wheat, soybean meal, barley, wheat bran, protein concentrate, limestone, salt, dicalcuim phosphate, vitamin and mineral premix, vegetable oil. Results showed that the starter optimum ration for layers from (0 - 6) weeks, consist of these Ingredients (9.40, 26.91, 16.38, 38.71,' 4.51, 0.95, 1.09, 0.25, 1.18, 0.25, (Received April 18, 2009) (Accepted September 28, 2009) 0.33)% respectively and from (6-12) week of (0, 73.43, 8.72, 0, 14.37, 0, 0.99, 0.25, 1.39, 0.25, 0.57) % respectively, from (12-18) week (0, 78.36, 6.17, 0, 12.02, 0, 1.44, 0.25, 0.87, 0.25, 0.61)% respectively, from (18 week - start of production) (0, 15.55, 13.85, 0, 3.81, 0, 4.25, 0.25, 1.16, 0.25, 0.86 )% respectively, and during productive period from (0, 66.93, 10.62, 0,0, 9.09,9.01, 0.25, 3.82)% respectively, and the cost of these ration was 160.6, 130.70, 123.60, 145.22, 195.95) Iraqi Dinar/kg respectively. Results also show sensitivity report of allowable increase and decrease in ingredient cost and in constraint values and the shadow price.
