The search was conducted in Dabba site for Agricultural Scientific Research at Lattakia region in the growing season 2011 to study some physiological and productive parameters for peanut cultivars under the row spacing effect and number of plants per hill, the experiment was designed by using split-split plot design with three replications. The treatments of experiment included four cultivars of peanut (ICGV 92022, C16 local 262, Souri, Al-Baladi) and three row spacing (40, 60, 80 cm) and two levels of number of plants hill-1 (one plant hill-1, two plant hill-1).

The research was conducted in Dabba site for Agricultural Scientific Research at Lattakia region in the growing season 2011 during the period from early June to mid-October. The experiment included four cultivars of peanut (ICGV 92022, C16 local 262, Souri, Al-Baladi), three row spacing (40, 60, 80 cm), and two levels of number of plants per hole-1 (one plant per hole-1, two plants per hole-1). The experiment was designed by using split-split plot design with three replications. The results of the study showed that Al-Baladi variety was superior to all other cultivars in weight pods/plant (108.8 g), weight seeds/plant (56.8 g), weight 1000 seed (914.7 g) with yield of seeds reaching (3529 kg/h). On the other hand, ICGV 92022 was superior in number of mature pods (29.22 mature pod), in number of seeds/plant (53.90 seed) and in yield (3058 kg/h). Regarding the effect of row spacing, the spacing 80 cm between rows had given the highest values significantly for yield attributes in comparison with row spacing 40 and 60 cm. Yet the highest yield per unit area obtained with row spacing was 40 cm. As about the effect of number of plants per hole-1, two plants hole-1caused significant decrease in yield attributes and significant increase in seed yield in comparison with one plant hole-1
The research was carried out during 2015 and 2016 seasons at Arab El-Mulk village, Banias district, in Tartous Governorate, to study the effect of planting peanut seeds size (mixture, small, medium and large), and spraying plants with bread yeast (Saccaromyces serevisiae) concentration of (4%) in three treatments (control, once and twice), on biological yield (BY), Economic yield (EY) and some physiological indicators; yield index (YI), Harvest index (HI), crop index (CI) and seed index (SI). The experiment design was set as split plot in a randomized complete block with four replications. The seeds size considered the main factor, while spraying yeast allocated the sub plots. The results showed that seed size caused significant increases in all of the studied indicators. The large seeds gave better values of (BY) 210 g, (HI) 30.56%, (CI) 44.12%, (SI) 74.85 g, except (EY) compared with mix, small and med seeds. Also the results showed that there were no significant increase between mixture and medium seed size in (YE) and (HI), but there was a significant increase in (BY) and (SI), on the other hand the treatments; spray yeast for once and twice had significant increases compared to the control, and the twice yeast spraying gave better values (215.22 g ,63.98 g, 29.64%, 42.37 % and 73.45g ) of (BY , EY ,HI, CI and SI) respectively, compared to the control. The interaction between seeds size and bread yeast spraying caused a significant increase which achieved 15.78 % in (BY), 23.99 % in (EY), 9.74 in (HI), 13.68% in (CY) and 7.87g in (SI) compared to the interaction between untreated treatment and small seeds size.
Seven cotton varieties (Rakka 5, Aleppo133, Aleppo 90, Aleppo 118, Aleppo 40, Deir 22, and Line124) were used in the study of some quantitative characteristics of cotton yield and its components (seed cotton weight per boll/g, 100seed/g weight aver age, lint percentage %, seed cotton weight per plant/g, total dry matter weight, seed cotton yield per unit area kg/ha), and physiological qualities (leaf area cm2, leaf area index %). The seven varieties were grown in Salhab (Al-Ghab region, Hama) in 2012 using randomized complete block design with three replications. The study included estimating variance, broad sense heritability, genetic progress, and genetic correlation between cotton yield and its components, which is to be used in breeding programs.
Antimicrobial compounds have been used for decades in poultry diets to increase performance and decrease morbidity particularly in broiler chickens. However, consumer pressure related to the potential development of antibiotic-resistant bacteria ha s resulted in the development of non-antibiotic feed additives that may also improve broiler erformance. In recent years, aromatic plants and their extracts have received attention as growth and health promoters. Such products have several advantages over commonly used commercial antibiotics since they are residue free and they are also, generally recognized as safe and commonly used items in the food industry. The antimicrobial properties of medical plants and their extracts have been widely reported because they consist of many active ompounds such as carvacrol, eugenol,which partition lipids in the bacterial cell wall and mitochondria, disturbing the structures and rendering them more permeable. Generally,medical plants are slightly more active against Gram-positive than Gramnegative bacteria. Medical plants are well known for their antioxidant activity and show a considerable effect on increasing the antioxidant capacity of chicken meat because they consist of many of active compounds such as tocopherol, carvacrol. Spices or their active principles have been reported to stimulate digestive secretions such as lipase, amylase and proteases.because they consist of many active compounds such as anothol, eugenol. Variable effects of medical plants and their extracts on the productive performance of broiler have been reported. The majority of experimental results indicate improved body weight gain or final body weight and feed conversion ratio.
This study was conducted in the Agricultural college, Damascus university during the period from March 1ST until the beginning of July 2001 to determine some productive parameters in local Syrian female rabbits. Seventy six adult females and twelv e bucks from the local rabbits were used in the present study. These animals were divided according to their color into five groups (6 females each). The colors were white, black, white and black , red, gray and one group (7 female) of brown color. The animals were housed individually in cages. The females of each group were randomly bred with tow bucks. The parameters studied were: conception rate, gestation period and litter size at birth, 7 days, weaning (28 days), 56 days and at the Age of 84 days.
