تم تنفيذ هذا البحث على محصول الفليفلة لدراسة تأثير الإجهاد المائي باستخدام ثلاث معاملات مائية: ري كامل ( 110 % من الاحتياج المائي ), و 75 % من الري الكامل, و 60 % من الري الكامل, و تم تصميم التجربة بطريقة القطاعات العشوائية الكاملة, استخدم الصنف البلدي لنبات الفليفلة, استخدمت طريقة الري بالتنقيط.
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.

The experiment was carried out during spring season 2016 to study the effect
of foliar spraying treatment with Tecamin Flower 2.5 ml/L in comparison with
distilled water, on growth of three hybrids of tomatoes at two different levels of
irrigation
(100 and 50 % of field capacity). Three sprays were conducted started
from flowering with two weeks’ interval. The results showed that ‘Finenss’ hybrid
had significant differences in plant height, branches per plant and leaves number per
plant. ‘Hadeer’ hybrid had superiority in dry matter ratio and content of chlorophyll
in leaves. Reducing the level of irrigation resulted in a significant decrease in
plant height, total branches number, versus an increase in the leaves number per
plant, total leaves area and the percentage of dry matter. The results showed that
the treatment with Tecamin flower led to a significant increase in all indicators
studied. The interaction treatments shoed that Hadeer hybrid irrigated in level 50
% and spraying of nutrient solution (Tecamin flower) had a significant increase in
dry matter ratio and chlorophyll content in leaves. While the hybrid Finenss which
irrigated in level 100 % with nutrient solution (Tecamin flower) had a significant
increase in leaves number per plant and total leaves area.
The research was carried out on the farm of Abi Jarash affiliated to the Faculty of Agriculture in Damascus during the 2012 agricultural season for the spring and fall seasons. The experiment was designed in a completely randomized sector method with the aim of evaluating the response of the two potato cultivars (Spunta and Daraga) to water stress.
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.
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 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.
