The objective was to evaluate milk yield, milk composition and milk fatty acids contents of lactating Harri ewes (n=24) receiving different concentrate to roughage (A 80:20; B 60:40; C 40:60 and D 20:80 C:R) rations. The results revealed that no differences (P = 0.29) in body weights of ewes were detected after parturition but body weights declined steadily as ewes continued on lactation. Group D produced more (P < 0.01) milk (1.38±0.5 kg/day) than groups A (0.76±0.5 kg/day), B (0.88±0.5 kg/day) and C (0.66±0.5 kg/day). Yields of milk fat, SNF, protein, lactose and minerals yields (g/day) were greater (P = 0.01) in group D than groups B and C not group A. No differences were found in milk fat, SNF, protein, lactose and minerals percentages (%). Groups D and A had more (P = 0.06) C18:2c (3.15±0.21 and 2.99±0.08 g/100g fat) than group B (1.98±0.54 g/100g fat) not group C (2.72±0.05 g/100g fat). Poly unsaturated fatty acids (PUFA) were increased (P<0.01) in groups A and D (4.07±0.18 and 4.49±0.27 g/100g fat) than groups B and C (3.34±0.12 and 3.41±0.23 g/100g fat). Lactating ewes' diet should include adequate ratio of roughage to increase milk yield and improve milk fat composition of unsaturated fatty acids.

This study aims to evaluate the toxic effects of insecticides on the foragers honey bee workers, Apis mellifera jemenatica. It tracks the effects of the insecticides, Deltamethrin, Malathion and Abamectin through the feeding by mouth, on the midgut epithelial layer, in order to show the histological changes. Histological study on samples of the foragers honey bee workers, after exposure to insecticides for 24 hours, was chosen as the average -concentration of the insecticide concentrations, which were used for each as follows: Deltamethrin 2.50 ppm, Malathion 3.125 ppm and Abamectin 0.1 ppm, in addition to the control group. Studying the effect of each insecticide individually and then comparing the reaction and impact of these insecticides on the tissue of midgut has showed that the insecticide Malathion was more harmful to epithelial tissue midgut in honey bees cells than Abamectin, while Deltamethrin had the least effect. Therefore, the life of the foragers honeybee worker depends upon the health and safety of the entire members of the beehive, so it is necessary to take into account, when using the application of insecticides, the continuity of life of the entire society adoption of individuals beehive on worker bees layer depends on their life on this layer of the bee community.

The present study was carried out in the lab. of plant tissue culture at King Abdulaziz University to test the response of four lemon cultivars to micro-propagation using BAP, Kin and 2,4D combinations. The used explants in this study were intermodal segments and collected from the one year old lemon seedlings which obtained from the Citrus Research Center, Najran, Saudi Arabia. The experiments were laid out in a split plot design using 4 replicates. The results revealed that there were significant differences due to genotypic and growth regulators effects and their interaction for all measured parameters except no of days to buds sprouting. Explants of ‘Shehri’ registered maximum values of no. of days to buds sprouting with 0.5mg/l Kin +0.5mg/l 2,4-D, % sprouted buds with 0.5mg/l BAP, % dead shootlets with 2mg/l BAP+0.5mg/l 2-,4D and length of primary shoots (mm) 1mg/l BAP+0.5mg/l 2-,4D. Shoots of ‘AlnEurka’ formed the highest no. of leaves with 0.5mg/l BAP+1mg/l 2-,4D. Low responses were observed for explants from ‘Shaary’, ‘Banzahir’ and ‘Aln-Eurka’ on culture medium supplemented with high concentration of BAP alone or with combination of 2,4D. There were observed no sprouted buds for explants of ‘Shehri’ on culture medium complemented with high concentrations of Kin in combinations with 2,4D. Lemon explants were successfully in vitro propagated using intermodal segments and combinations of BAP, Kin and 2,4D at low concentrations.

Field experiments were carried out for two consecutive seasons at the Experimental Station of Soil and Water Department‚ Faculty of Agricultural‚ Assiut University, to study the effect of both irrigation intervals and methods of potassium application on yield and yield components of wheat (Triticum aestivum L.) beside potassium content in plant and soil. The experimental design was a split plot design with four replications. The main plots were three irrigation intervals (15, 21 and 28 days), while the subplots contained two methods of potassium application (side dressing and fertigation). Results indicated that, shorter irrigation intervals improved yield and yield components of wheat crop. The best yield was obtained from 15 days irrigation interval followed by 21 days. Longer irrigation interval (28 days) produced the least yield and yield components due to water stress conditions. Applying potassium with irrigation water improved yield of wheat crop and potassium contents in grain and straw yields compared to side dressing application. Also it increased the available potassium in soils.

Comparing between different methods for classifying 12 maize inbred lines to heterotic groups was achieved using general and specific combining ability effects; agronomic traits to the maize inbreds per se; and ISSR-markers. The results of line-tester design showed that Giza656 lines had the highest yield for the cross with Gemmiza 1021 tester (7.20 ton per hectare) at Nubaria, while Giza655 lines had the highest yield for the cross with Gemmiza 1021 tester (8.24 ton per hectare) at Gemmiza. Regarding Heterotic specific and General Combining Abilities, the inbred lines were grouped into three groups as their testers were, but groups differed from Nubaria to Gemmiza locations. The classification due to Inter Simple Sequence Repeats markers have agreement with pedigree data more than the HSGCA and agronomic characters, because the HSGCA method affected by testers, lines, environments, and the interactions between all of them, also, agronomic character method need to plant the inbreds and evaluate them at more locations and more seasons .Furthermore, all these cautions will not discard the environmental effects but they will reduce it to the minimum values. On the other hand, molecular marker will keep time and efforts needed to evaluate the inbred lines.

Indoor and outdoor airborne particulate matter (PM10 and PM2.5) were sampled from homes with different heating facilities, located at Sakaka city, northern of Saudi Arabia during winter season. Elemental composition of PM10 and PM2.5 samples, including Al, Ba, Be, Ca, Cd, Co, Cr, Fe, Ga, K, Li, Mg, Mn, Na, Ni, Pb, Se, Te and Tl, were analyzed using inductively coupled plasma-mass spectroscopy (ICP-MS). Black carbon (BC) was also measured using EEL-type Smoke Stain Reflectometer. Results showed that the highest indoor concentration PM2.5 (541.67 μg m ) and PM10 (1201.39 μg m ) were found at homes using wood burning as heating facility. The most dominant metals were Na, Fe and Al in the investigated PM2.5 and PM10 samples. The highest concentrations of black carbon were found in homes using wood burning as heating facility. For similar homes in heating facilities, we can deduce that by increasing the number of smoking persons the value of BC increased.

Two field experiments were carried out in the experimental farm of Faculty of Desert and Environmental Agriculture, Fuka, Matrouh Branch, Alexandria University, Egypt, during two successive seasons 2012/2013 and 2013/2014 to study the effect of seed priming with Ascorbic and Salicylic Acids and spraying with silicon on drought tolerance of two barley cultivars, Giza 126 and Giza 2000. Six treatment were used as follows: Seed priming with Ascorbic acid (AA) and irrigation till heading (T1), seed priming with Salicylic acid (SA) and irrigation till heading (T2), seed priming with distilled water and irrigation till heading (T3), spraying with silicon and irrigation till heading (T4), dry seeds cultivation and irrigation till heading (T5) and dry seeds cultivation and all season irrigation (T6). The results indicated that post anthesis stress decreased grain yield by 17.1 % and 100-grain weight by 11.96 %, as an average of the two seasons. Hydropriming and osmopriming with salicylic acid, in addition to spraying with silicon, decreased the effect of drought and barley plants gave comparable grain yield to that of non-stress conditions. Barley cultivar Giza 126 was more tolerant to late drought compared to Giza 2000 cultivar with S values of 0.58 and 1.42, as an average of the two seasons, respectively.
