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.
This study was carried out in a protected area at Rangeland and Dry
Environment Research Station, belongs to ACSAD and Aleppo university in
the Muslumieh, Aleppo, during 2004, by cultivating 11 plant species belong to
three different families, Fab
aceae (3 species), Poaceae (7 species) and Rosaceae
(one species), using 4 moisture Levels (5, 10, 15 and 20 mm), and 6 seeding
depths (0, 1, 2, 3, 5 and 7 cm). Results showed that the seeds of all the
investigated species failed to germinate at the moisture level of 5 mm, while
Onobrychis sativa (36.2%), Agropyron elongatum (53.9%), Agropyron cristatum
(36.1%), Phalaris tuberose (41.1%), Dactylis glomerata (12.2%) and
Sanguisorba minor (1.12%) germinated under 10 mm humidity. The seeds of all
investigated species germinated at the higher moisture levels (15 and 20 mm),
but the germination ratio varied between the species. The seeds of all studied
species were capable of germinating when placed at the soil surface and seeding
depth of 3 cm. The seeds of Agropyron elongatum (73.3%), Agropyron cristatum
(13.3%), Phalaris tuberosa (36.7%) were capable of germinating at depth of 5
cm. The seeds of all studied species failed to germinate at a the planting depth
of 7 cm.
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
