Özet
A field trial was conducted to observe the effects of different irrigation strategies on the yield and the water use, oil
content and marginal return of sunflower which was irrigated by means of a drip system during 2010 and 2011 under
Çukurova condition of Turkey. The irrigation strategies include three irrigation intervals (A1
: 25 mm; A2
: 50 mm; A3
: 75
mm of cumulative pan evaporation) and six water levels (WL) based upon the percentages of cumulative pan evaporation
(WL1
= 0.50, WL2
= 0.75, WL3
= 1.00 and WL4
= 1.25). In addition, WL5
= PRD50 and WL6
= PRD75 treatments were
evaluated. They obtained water from alternative laterals 50% and 75% of the WL3
treatment. Additionally, a nonirrigated treatment (NI) was included as control plot in the experiment. In each of the experimental years, the largest and
the smallest average yields were acquired from the A2
WL4
and NI treatments, respectively. The oil content and fatty acid
composition were significantly affected by irrigation strategies. The oil content increased with the increasing amount of
irrigation. Among all irrigation intervals, PRD-50 (WL5
)treatment provided the largest water use efficiency (WUE) and
irrigation water use efficiency (IWUE) values in both growing seasons. In order to attain higher yields and a generated
the marginal return, A2
WL4
irrigation regime is suggested for sunflower production in the Mediterranean region. A2
WL3
water strategy is proposed for an acceptable marginal return in case of water shortage.
