نفذ البحث في موقع دبا للبحوث العلمية الزراعية في منطقة اللاذقية خلال الموسم الزراعي 2011 بهدف دراسة بعض المؤشرات الفسيولوجية و الإنتاجية لمجموعة من أصناف الفول السوداني تحت تأثير المسافة بين الخطوط و عدد النباتات في الجورة. صممت تجربة عاملية باستخدام القطع المنشقة لمرتين مع ثلاثة مكررات و تضمنت معاملات التجربة أربعة أصناف هي: ICGV 92022، س16 محلي 262، سوري، البلدي و ثلاث مسافات بين الخطوط 40، و 60، و 80 سم و مستويين لعدد النباتات في الجورة (نبات واحد/جورة و نباتين/جورة).
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.
