هدف البحث إلى دراسة تأثير خلطات عدة من أوساط النمو في نمو شتول الفليفلة، و في مقدرتها على تحمل صدمة التشتيل. استخدم من أجل ذلك الصنف البلدي "قرن الغزال" من الفليفلة، و خمسة أوساط تختلف في نسب مكوناتها الحجمية، اشتملت على البيت – موس منفرداً, كما استخدم خلطتين مؤلفتين من وحدات حجمية متساوية من البيت–موس, و على كل من التراب أو الرمل, و خلطة واحدة من التراب و الزبل البقري بنسبة ، و خلطة من الزبل البقري المتخمر، و التراب، و الرمل بنسبة 1:1:1. نفذت التجارب في بيت بلاستيكي غير مدفأ في المشتل الزراعي التابع لكلية الزراعة بجامعة تشرين على وفق التصميم العشوائي الكامل, بثلاثة مكررات للمعاملة الواحدة، و بمعدل خمسة عشر نباتاً للمكرر الواحد. أظهرت النتائج أن الأوساط المحتوية على الزبل البقري المتخمر هي الأكثر تأثيراً في نمو الشتول، و تمثل ذلك بزيادة أطوال الشتول، و أعداد الأوراق، و بمساحة مسطحها الورقي، و كذلك في زيادة الوزن الرطب للمجموعين الخضري و الجذري للشتول، و كان هذا الدور أكثر وضوحاً في الوسط المحتوي على التراب و الزبل البقري المتخمر بنسبة 2:1.
This research work aimed to study the effect of different mixtures of growing media on pepper seedlings and their ability to withstand transplanting shock.The variety QarnAlgazal of pepper and five mixtures of growing media were used.The mixtures included bitmoss alone,bitmoss with equal volume of soil or sand,soil and cow manure in a ratio of 1:2,and cow manure with soil and sand in a ratio of 1:1:1. The experiments were implemented in aplastic green house without heating in the nursery farm of the faculty of Agriculture,Tishreen University.The completely randomizel design was adopted with three replications for each treatment and 15 plants for each replication. The results showed that themedia containing cow manurewere the more effective ingrowth of sapling as represteded by the increased hieght of sapling, number and area of leafs,fresh weight of both biomass and roots of sapling.The effect was very clear in the media containing cow manure and soil in the ratio of 1:2.

The research aimed to study the effect of size of container on the growth of
seedlings pepper "Snapper". Two different sizes of plastic containers, with
dimensions 8×8 cm and12×12 cm were used, Results showed that the use of
containers with large
dimensions had increased the growth of seedlings
compared with the use of smaller ones. A significant increase, of about 14%
was observed in the average length of seedlings and about 16% in the average
number of leaves produced in the large containers as compared with seedlings
produced in smaller ones. Also the fresh wet weight, whether for the plant or its
separate parts was significantly higher in seedlings produced in the large
containers. The plant fresh wet weight in the large container was 26.98 g vs.,
2.27 g in the smaller ones.
This study is aimed at studying the effect of using four species of
bacteria Plant Growth Promotion Rhizobacteria (PGPR) Azotobacter
chroococcum, Rhizobium leguminosarum, Bacillus megaterium and
Frateuriaaurantia on the growth, yield and reducing
the effect of
Cucumber mosaic virus(CMV) on pepper plants in a greenhouse
experiment. The observed growth parameters were: plant height, foliage
fresh weight, root fresh weight, fruit weight in a green house expirment
in Tartous in the season 2016/2017.
This search aims to study the efficiency of using“Biotolerance” as a
fertiliser; by a foliar spry on Pepper seedling. Four varieties were
used (Marcony, California wander, Maroty-7 andRobber). The
results showed that the treatment by the fertilizer resulted in an
increase in growth thorough the plant length increasing.
The aim of this study was to test the effeciency of some organic and bio fertilizers in
improving the seeds germination and transplants growth of pepper Capsicum annum L.
local variaty" Qorn Algazal":by using two commercial compounds; organic (Hube
st) and
one bio (EMI) fertilizers. Two experiments were used; the aim of the first was to study the
effect of these fertilizers on germination of seeds in Petri dishes and plastic peatmoss peds.
Whereas the aim of the second experiment was to evaluate the effect of the fertilizers on
the pepper transplants growth that prepared in the 5 * 5 Striopor peatmoss plates placed in
un warmed plastic tunnel.
The results showed that the soaking of pepper seeds in the tested fertilizers, provoked
and the germination increased the seeds, vigor, with a significant performance of the bio
fertilizer.
The results also showed that the treated transplants with the tested fertilizers gave an
increase of the transplants growth ratio (the height, leaves number and foliar surface area,
the dry and wet weight) with a significance superiority of the bio fertilizer.
The research was carried out on (960) broiler chicks of the hybrid Hibrd in
the Poultry Unite of Kharabo–Agriculture Faculty–Damascus University,
during 27/10/2003 and 23/12/2003.
The chicks were distributed randomly since the first day of age int
o four
experimental groups, every group contained 240 chicks distributed as four
replicates, every replication contained 60 chicks, the area of the replication was
5.5m2 and the density was 11 chicks/m2. Every replication is an independent
sector from byre is open type on deep litter, all conditions of keeping and
caring were the same for all birds of replications.
The purpose of research was to study of effect of using different levels of the
energy and raw protein into mixtures of (pre-starter) since the first day until
sixth day of age on absorption of yolk sac, growth of digestive system ,and some
productive parameters of broiler. 48 chicks were dissected, the chicks were
distributed as 16 chicks in the first day and 16 chicks in the fourth day and 16
chicks in the sixth day of age, from every group 4chicks were evaluated.
