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.
Predicting crop yield response to irrigation level is increasingly important to
optimize irrigation under limited available water and for enhancing
sustainability and profitable production. This study was carried out to evaluate
the performance of
CropWat model in predicting deficit irrigation effect on
cotton crop, and to explore some alternatives for cotton irrigation. Crop yield
and water use data were collected from a 3-yr (2007-2009) field experiment to
assess the response of drip-irrigated cotton to deficit irrigation (DI).
