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
Laboratory experiment was conducted in the laboratories of field
crops department, Faculty of Agriculture, Damascus University,
during the year 2011, in order to screen some lentils genotypes to
osmotic stress at seedling stage.
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.
