| Abstract | ||||
| WO field experiments were conducted at El-Karada water management station, Kafr El- Sheikh Governorate, Egypt management station, Kafr El- Sheikh Governorate, Egypt during two successive summer seasons 2008 and 2009, to study the effect of irrigation water management for sunflower production through irrigation escaping of some irrigation events, during the growth season on yield, yield components and quality of sunflower crop. Randomized complete block design with three replications was used. The irrigation treatments included five treatments, conventional irrigation along the growing season every 15 days (T1), escaping irrigation at the age of 30 days from sowing = 3rd irrigation (T2), escaping irrigation at the age of 45 days from sowing = 4th irrigation (T3), escaping irrigation at the age of 60 days from sowing = 5th irrigation (T4) and escaping irrigation at the age of 75 days from sowing = 6th irrigation (T5). The highest values of seed yield, oil percent, oil yield and 100 seed weight were obtained under T4 as well as the highest net return of water unit and economic efficiency. Therefore, escaping sunflower irrigation at the age of 60 days from sowing (the 5th irrigation) could be recommended to maximize sunflower production under the condition of studied area. | ||||
