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.

Farm animals have a high economic importance because of their important products such as meat, milk, hair as well as skin, not only in our country but also all over the world. These animals can be infected by serious pathogens, external and   internal parasites causing severe damage, which result in losses of animal production. Accordingly, the study of external parasites with light microscope and scanning electron microscope were recorded, to clarify the exact composition of species. Also, differences in the morphological characteristics between the two Myiasis species: Oestrus ovis (Linnaeus, 1758)and Cephalopina titillator (Clark 1797), were investigated.

The almond seed wasp Eurytoma amygdali Enderlein (Eurytoma amygdale End) is an important insect on almonds Amygdalus spin 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.

The study showed that the average amount of global production of cotton during the period (2004-2008) was estimated at 20.849 million tons. 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.

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 biscuit 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 ogran heart for groups rats fed on biscuits fortified with celery seeds and cinnamoin 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.

Four plant oils namely Barka, Sesam, Garlic and Almond were prepared as emulsifiable con centrate (EC). Polyethylene glycol 600 dioleate (PEG 600 DO), Toximol R and Toximol H were used as emulsifiers while xylene and toluene used as solvents. Four formulations only passed successfully (F1, D2, C3 and E5) in the Physicochemical properties according to the standards of WHO. The results indicated that the successful prepared formulations showed different degrees of effectiveness against second stage juveniles of Tylenculus semipenetrans under laboratory conditions. Second stage juveniles seem as paralyze at 24 hrs, whereas this effect disappears completely after 72 hrs in case of Almond and Barka. On the other hand, the effect of Sesam and Garlic showed a slight effect at 24 hrs and increased gradually to give highly effectiveness after 72 hours. According to EC50 values at 72 hrs, Garlic was more effective than Sesam. The respective EC5o values were 0.6 and 2 mg/ml. These results emphasized the promising effect of certain plant oil formulations including Garlic and Sesam oil against pathogenic nematode, and that such formulation might be used for nematode control in small areas, as gardens and plant nursery.

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.

Two Field experiments were conducted during the two summer seasons of 2007 and 2008 at EL-Serw Agricultural Research Station, Damietta Governorate, Egypt to study the effect of the time removal of weeds on associated weeds, growth, yield and its components in direct seeded rice in salinity land. Echinochilon crus – galli, Echinochilon colunum, Cyperus difformis, Cyperus longus and Dicanthium annulatum  were the major weed species. Competition beyond 8 and 10 weeks from sowing and weed competition for the whole season caused drastic reduction in the panicle length, number of panicles / m2 weight of 1000grain and grain yield. Grain yield of rice increased significantly with the increase of the duration of weed-free period. Weed free for the whole season and weed free for 10,8,6 and 4 weeks from sowing and weed removal at 4 and 6 weeks from sowing gave good results in this respect in both seasons. The period during 4 and 6 weeks after sowing was found to be an important factor in crop/weed competition. Weed cause 20 to 95% yield loss. Direct seeded rice ecosystems are most vulnerable to weed competition. Weed free is the most common and predominant method of control and is cost-effective. In direct seeded rice emergence of weeds begins with the germinating rice seedlings. This leads to competition between weeds and crop right from the very early stages. The degree of yield losses would depend on the type of weeds and the stage and duration of their competition with the crop. It could be concluded that the critical period of weed competition in direct seeded rice among 4- 6 weeks from rice sowing, thus it's important to remove the weeds at this time.
