يهدف البحث إلى تحديد الاحتياج المائي لنبات الفليفلة باستخدام تقنيات الري بالتنقيط، و الري بالميكروجيت (رذاذ خفيف)، و الري بالرذاذ (رش)، و الري السطحي (خطوط)، و قد تم الحصول على النتائج التالية: لم يتم الري خلال شهري آذار و نيسان و الثلث الأول من أيار حيث كانت كمية الأمطار الفعالة اكبر من الاحتياج المائي للنبات. بلغت كفاءة الري لنظم الري المستخدمة (تنقيط، ميكروجيت، رذاذ، سطحي) كما يلي: 0.921 -0.886 - 0.869 – 0.70 على التوالي. بلغ متوسط احتياج النبات الحقيقي اليومي من مياه الري خلال فترة الري بالنسبة لنظم الري المستخدمة (تنقيط، ميكروجيت، رذاذ، سطحي) كما يلي: ( 1.084-1.132 -1.152 -1.426) ليتر/يوم على التوالي. بما أن الري السطحي هو الشاهد فقد بينت النتائج انه يمكن توفير كمية من المياه في الهكتار الواحد خلال فترة الري مقدارها 3595 م3 باستخدام الري بالتنقيط، و توفير 3222 م3 عند الري بالميكروجيت، و توفير 2858 م3 عند الري بالرذاذ. بلغت كمية الإنتاج (كغ/م2) وفق المساحة المخصصة لكل نظام ري (التنقيط، الميكروجيت، الرذاذ، السطحي) وفق التالي: 3995- 3389- 3315- 2910 على التوالي.
The research aims to determine the water requirements by using drip irrigation, microjet irrigation, sprinker irrigation and surface irrigation for pepper. The study showed the following: • The pepper don’t need to irrigate through mars and april and the first third of may because the effective rainfall is more than the trees water requirement. • The irrigation efficiencies were 0.921, 0.886, 0.868 and 0.70 for drip, microjet, sprinker and surface irrigation, respectively. • the dayly irrigation averages for one plant by field studying were 1.084, 1.132, 1.152, 1.426 liter/day for drip and microjet and sprinkler and surface irrigation, respectively. • By regarding the surface irrigation as witness we can economize of water in one year for one hectare 3595 m3, 3222 m3 and 2858 m3 by using drip, microjet and sprinker irrigation, respectively. • The product quantities were 3995, 3389, 3315, 2910 by using drip, microjet, sprinker, and surface irrigation, respectively.

The experiment was conducted for one growing season 2011 at Teezen
Research Station in Hama Research Center-GCSAR in order to determine
water requirements, crop coefficient (Kc) and the effect of different irrigation
systems on productivity of pea
nut crop. Four methods of irrigation were used
(drip، sprinkler، mini sprinkler and surface irrigation) with three replications
for each . Experiment was designed on the basis of randomized complete block
with one water treatment (75% out of the field capacity). The results showed
superiority of drip irrigation in terms of water consumption, and total water
consumption (6522 m 3/h), which led to savings in irrigation water by (60.14%),
compared with traditional surface irrigation, with a consumption (13495 m 3/
h). It also outperformed drip irrigation when (p<0.05) in crop yield, reaching
productivity 5920 kg/ha, an increase of 22.57%, and total water use efficiency
1.91 kg/m3, compared with the (control) surface irrigation, reaching
productivity (4820) kg/ha. Followed by methods for: irrigation sprinkler sprays
small, with a water requirement (8999 and 9396 m 3/ h), and the efficient use of
water (0.67 and 0.58) kg/ m3, and the percentage of savings in water (36.65 and
31.98%), respectively, compared with surface irrigation traditional Phonology
developing did not show significant differences between irrigation methods in
terms of the dates of germination, flowering and maturity.
The study aimed to estimate water requirements for Anise, the crop
coefficient, and the effect of three water stress treatments out of full irrigation
amount respectively) on its yield
This research on pepper crop conducted to impact water stress using
three transactions water are: full irrigation (100% from water
requirement), 0.75% of full irrigation, and 60% of full irrigation,
has been designed experiment in a way random sectors full, use a
variety of municipal plant peppers, and used drip irrigation method.

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 i
ncluded 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.
