Two field experiments were conducted during the two successive seasons of 2007 and 2008 at the Agricultural Experimental Station of Agricultural Research Center, at EL-Serw, Damietta Gover-norate Egypt, to study the effect of the bio horm and weed control treatments (Bentazon, Py-razosoulfuron, Fenoxaprop, Penoxsulam, Bentazon + Fenoxaprop, Bentazon + Penoxsulam, Pyrazosoulfuron + Fenoxaprop, Pyrazosoulfuron + Penoxsulam, twice hand weeding and un- weeded check ) on growth, yield, its components and NPK percentage in grains of direct seeded rice as well as associated weeds in salinity soil. Results illustrated that appli-cation of bio horm increased fresh and dry weight of total weeds. Spraying bio horm after 50 days from sowing (DFS) markedly increased rice growth characters (plant height, number of productive till-ers, fresh and dry weight of rice plants), yield and yield components (panicle length, number of pani-cles/m2, weight of 1000 grain, grain and straw yield) and N, P and K% of grain rice, as compared with untreated treatment. All weed control treat-ments caused significant reduction on number, fresh and dry weight of total weeds/m2 after 60 DFS in both seasons. Pyrazosoulfuron treatment gave the highest decrease in total number of weeds followed by Pyrazosoulfuron + Penoxsulam and Pyrazosoulfuron + Fenoxaprop treatments. Pyrazosoulfuron + Fenoxaprop treatment gave the highest decrease in total fresh weight of weeds followed by Bentazon + Penoxsulam, Pyrazosoul-furon and Pyrazosoulfuron + Penoxsulam, respec-tively in the first season. While, in the second sea-son Pyrazosoulfuron treatment gave the lowest values of total fresh weight of weeds. Meanwhile, Bentazon + Penoxsulam was more effective than other treatments in reducing the dry weight of total weeds in both seasons. All herbicidal treatments and hand weeding increased significantly growth, yield, yield components and chemical composition of grain rice. Bentazon + Penoxsulam was superior treatment for increasing number of productive tillers, number of panicles / m2, 1000- grain weight and grain and straw yield as well as NPK percent-age of rice grains in both seasons. While, the same treatment Bentazon + Penoxsulam recorded the highest values of plant height, fresh and dry weight of whole plant and panical length in the first season. While, Pyrazosoulfuron + Penoxsulam gave the highest increment in plant height, fresh and dry weight of whole plant and straw yield in the second season. The interaction between bio horm and weed management treatments had significant effect on total fresh and dry weight of weeds, num-ber of productive tillers and 1000 grain weight. Pyrazosoulfuron produced the maximum values of number of productive tillers when bio horm was used in the second season, while, application of Bentazon + Penoxsulam gave the highest values of 1000 grain weight when bio horm was used in the second season. It could be concluded that using the bioregulator (bio horm) resulted in incre-ment of growth and productivity of rice crop under salinity soils. Using the combinations of herbicides caused more reduction of weeds and increased rice grain yield.

A detailed survey was carried out for 8 Foster grapefruit (Citrus paradisi Macf.) groves in Sennar area (13˚ 37΄ N, 33˚ 37΄ E) representing Sudan Central Clay Plain. Trees were budded on Sour orange (Citrus aurantium L.). Soil and leaf samples were collected and analyzed according to standard procedures. Soil analyses included particle size distribution, pH (paste), ECe, SAR, N, P, K, Ca, Mg, Na, Zn, Fe and Mn. Leaf nutrient  levels  determination included N, P, K, Ca, Mg, Zn, Fe and Mn. Yield per tree was recorded for one season and quality parameters were measured for fruits sampled from representative trees. Results indicated that, soil texture of the orchards ranged between clay and clay loam. Although the orchards were receiving the same cultural practices, yet, they were significantly different in some soil and plant constituents. All orchards were non-saline and non-sodic of slightly to moderately alkaline reaction. Soil and plant were deficient in nitrogen and zinc with high leaf phosphorus, magnesium, iron and deficit calcium levels. Mean fruit yield ranged between 0.93 and 7.76 tons ha-1 with an average of 4.35 tons ha-1, which is considered lower than world average. A low % TSS (total soluble solids), low ascorbic acid content and high % green color on fruit surface are evidents of low quality fruits. The low yield and poor quality fruits in this area were attributed to unsuitable soil conditions and the poor management practices

Vegetable production provide great value in the agricultural production sector in the Kingdom of Saudi Arabia. Growers and agricultural engineers need a comprehensive database in Arabic lan-guage that can be available for use any time any where. Therefore, this research project was initiat-ed. The computer program was developed using Visual Basic Net 2005 which is one of the ad-vanced visual programming languages. We took into consideration easy usage and coherence be-tween all program components. Main results in-clude computer program with the data base, which includes: vegetable crops, diseases, insect pests and other pests that attacks vegetable crops, management tactics, cultural practices, irrigation requirements, planting dates, data search. Fur-thermore, field trips have been carried out to some vegetable farms in all the Kingdom regions. A digit-ized map of the Kingdom has been added to the program in addition to crop water and heat re-quirements. Various search capabilities have been developed in the program. After the completion of the program build up, verification trips have been carried out for five regions in the presence of farm-ers and extension specialists of the different direc-torate of the Ministry of Agriculture to test the accu-racy of steps used in the program. A manual for the computer program as well as leaflet on pro-gram set up and usage have been included. It is recommended to make this program available at the internet and distribute copies to the Ministry of Agriculture and its directorates as well as farmers.

Experiments were carried out on honey bee colonies (Apis mellifera) during the winter of 2008 and spring of 2009 using colonies wintered with five levels of varroa infestation (0.0, 3.8, 9.0, 13.1 and 22.9%) in the Central Region of the kingdom of Saudi Arabia. The goal of the present work is to determine varroa treatment thresholds and colony collapse level. Response variables examined included varroa mite infestation level (%), cm2 of brood number of frames of brood, number of frames covered with adult honey bees and mites recovered on sticky boards. The data obtained reveled that no significant differences were noticed in cm2 of brood, number of frames of brood, and number of frames of bees in colonies (range of 0.0 to 9.0% varroa infestation or 0.0 – 0.9 mites/bee). Colonies with 13.1% infestation (0.13 mites/bee) exhibited a significant reduction in all measures of performance. The present results suggested that honey bee colonies can tolerate a level of 9.0% varroa infestation (0.9 mites/bee) during the winter without evidence of colony injury. It also suggested that 13.1% infestation (0.13 mites/bee) is the colony collapse or economic injury threshold in the Central Region of the Kingdom of Saudi Arabia. Also colonies with 12.3 or more mites falling on sticky boards after 48-hour period were likely to have lower populations of bees and brood the following spring.

Garlic is promoted for use as a preventive factor against the formation of cancer. Although several compounds in garlic may have anti- cancer properties, the dially sulfide compounds are said to play a major role. garlic is known to help in regulating blood sugar levels. Therefore, yoghurt was manufactured by using the aqueous extract of garlic to produce a healthy yoghurt. Different concentration of this extract; 0.1, 0.2, 0.3, 0.4 and 0.5% were added to yoghurt milk. Results showed that 0.1% of garlic extract was the best concentration which gained the highest score. The resultant yoghurt treatments were analyzed chemically and organoleptically when fresh and after storage at 5 + 1°C until 15 days. Yoghurt acidity was gradually increased during storage at 5 ± 1°C until 2 weeks, either for control or different treatments. On the other hand pH took an opposite trend of acidity. The resultant fresh yoghurt had high acetaldehyde, diacetyl, TVFA, viscosity values than control, whereas it showed low whey synersis. During storage at (5 ± 1°C) acetaldehyde, diacetyl decreased while TVFA, viscosity, whey synersis values were increased. Statistical analysis showed high significant difference (a 0.05) for acidity, TVFA, viscosity, diacetyl values and non significant difference (a 0.05) for acetaldehyde content between treatments and during storage.

ABSTRACT   Iron deficiency anemia is considered one of prevalent patients in developing countries, whereas it is well known that wheat flour is deficient in iron, hence, in this study wheat flour (72%) extraction fortified with celery seeds and cinnamon bark meal individually as a natural sources of iron at levels 5, 7.5 and 10 g/100 g wheat flour and preparation of biscuit samples. Iron content in wheat flour, celery seeds and cinnamon were determined. Biscuit samples were sensory evaluated and baking quality tested. Total iron and available iron were determined in biscuit samples. Biological evaluation for experimental rats designed and histopathological examination was tested for heart organ of rats. The results showed that wheat flour, celery seeds and cinnamon contained from iron 1.98, 57 and 50 mg/100 g respectively. Total iron and available iron increased in biscuits samples by increasing celery seeds and cinnamon additives compared with unfortified biscuits (control). Sensory evaluation of biscuit samples showed slight decrease in color, crunchiness and appearance while odor and taste significantly improved by increasing celery seeds and cinnamon additives compared with control. Baking quality of biscuit samples indicated increasing in weight, while volume, diameter and thickness slightly decreased by increasing celery seeds and cinnamon additives compared with control. Biological evaluation revealed that mean values of hemoglobin, hematocrit, red cell count, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, serum iron and serum ferritin significantly improved after 8 weeks in groups rats fed on biscuits fortified with celery seeds and cinnamon compared with control. Histopathological overhaul declared amelioration in organ heart for groups rats fed on biscuits fortified with celery seeds and cinnamon compared with anemic control.

\{ In view of balady bread in Egypt is considered as backbone in diets, accordingly, in this study wheat flour (82%) extraction treated by microwave at 2,4 and 6 minutes, that target to modify starch wheat flour by heating. The rheological properties were studied by using farinograph and extensograph apparatus. Falling number and amylose percent were determined. Balady bread samples were sensory evaluated and staling rate was evaluated. The wheat flour, crust and crumb layers of balady bread were examined by scanning electron micro scope (SEM). The results of farinograph indicated that, water absorption arrival time, dough development time and dough stability increased while dough weakening decreased in wheat flour treated by microwave compared with wheat flour untreated (control). The results of extensograph revealed that, dough extensibility, resistance to extension and dough energy increased while proportional number decreased in wheat flour treated by microwave compared with control. Falling number decreased while amylose percent increased when microwave treatment increased from 2 to 6 minutes. Sensory evaluation showed slight decrease in values of both color crust and color crumb while, values of both taste and flavor slightly increased but not significantly different, meanwhile, values of crumb distribution significantly increased in balady bread samples prepared from wheat flour treated by microwave compared with balady bread prepared from untreated wheat flour (control). Wheat flour treated by microwave led to delay staling of balady bread and imilorated freshness of balady bread. The examination by scanning electron microscope (SEM) showed that average size of starch granules increased from 26.10 µm in untreated wheat flour (control) to 29.37 µm in treated wheat flour by microwave at 6 minutes.

Recommended application was done by spray regime for two pesticides, namely diniconazole, fenitrothion and a plant growth regulator (gibberellic acid) and their mixtures. Their residues were determined after different successive treatments in and on grape fruits in two consecutive years. The initial deposits of the fungicide diniconazole when used alone were 0.49 and 0.50 ppm for 2006 and 2007, respectively. While the initial deposits of fenitrothion reached to 11.35 and 11.19 ppm for the same interval, respectively. Initial deposits of the plant growth regulator gibberellic acid were 30.52 and 30.42 ppm for the same period, respectively. After mixing the tested pesticides and the plant growth regulator, the initial deposits loss reached 38.77 and 42.0 % for diniconazole, 43.08 and 48.16 % for fenitrothion and 6.88 and 7.00 % for gibberellic acid for the same seasons, respectively. A significant degradation was recorded with the mixture of the two tested pesticides and plant growth regulator compared with that occurred when pesticide was used alone at' the two studied seasons.

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.
