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.
Aniseed Crop, Pimpinella anisum L. is one of the important medicinal and
aromatic plants in Syria and the world. It has very important economic value,
appear in its medicinal and multi-uses. Weeds considered as the greatest
obstruct for aniseed pr
oduction and hand picking is commonly used for weed
control. So the investigation was carried out to evaluate the effect of the
herbicide, Afalon on the weeds of aniseed and its phytotoxicity. Afalon
treatment resulted in high efficacy for the broad leaves weeds (92.4 %, 97.1 %
and 96.1 %) for the half rate, field rate and double field rate, respectively and
(5.8 %, 23.9 % and 29.1 %) for the narrow weeds. The treatment of double
field rate gave a high yield (715.3 Kg/ha.) that was equal to weeded plots (777.8
Kg/ha.), and the field rate treatment (673.6 Kg/ha.) was significantly superior
to other treatment. This indicated the importance of spraying aniseed crop with
Afalon especially when hand picking not possible. Phytotoxicity effect were not
recorded on anise plants. Some other plants were not affected by the herbicide
like Ammi majus and coriander, those are belong to the same family, Apiaceae.
This research was carried out at the farm of Faculty of Agriculture,
Damascus University, during 2010-2011 growing season to determine the effect
of seedling rate on yield traits (plant number at harvesting, plant height,
number of umbels/plant, n
umber and weight of seeds/ umbel, plant dry weight,
seed yield and harvest index.) of four ecogenotypes of Anise plants, (Pimpinella
anisum L.) collected from different places of Syria: Damascus countryside
(Hena, Saasaa), Homs and Edlib. Sowing rates were 10, 15 and 20 Kg/ha.. Trial
was laid out using completely randomized block design with three replicates for
each treatment. Results showed that studied traits differed according to seeding
rate and the ecotype. There were significant differences for the treatment of
seeding rate of 15 kg/ha., on seed yield. Regardless the ecotype, increasing the
seeding rate up to 20 kg/ha. resulted in maintenance of highest number of
plants/unit area, but accompanied with reduction in fertile umbels and seed
weight. Statistical analysis showed that the ecotype of Edlib recorded the
highest seed weight/ plant and highest seed yield/ planted area, especially with
the seeding rate of 15 kg/ha. However, the results showed the seed components
of Anise (plant number at harvesting, weight of seeds/ plant) and seed yield
were affected by the ecotype and seeding rate.

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.
