Abstract EN
Abiotic stresses represent a major impediment to crop productivity, especially in arid regions.
Thus, over two years of 2014 and 2015, a field experiment was undertaken at El Nubaria region, Egypt to assess the productivity and water use efficiency (WUE) of sunflower as affected by plant-ing dates (April 21, May 21, and June 21) and irrigation levels (ET100 %, ET85% and ET70 %,).
Re-sults clarified that leaf chlorophyll a content was higher by sowing in May than in either April or June sowings, while leaf carotenoides of plant sown in May or June surpassed those sown in April.
The minimal value of proline was obtained with sowing in May.
Sowing in May increased plant height by 52.2 and 22.3 as well as LAI by 19.3 and 73.1 % than sowing in April and June, respectively.
The reductions in seed yield, oil yield and WUE amounted to 10.5 and 12.8, 13.7 and 18.3 as well as 11.8 and 9.8 % with April and June sowings, respectively, compared to May sowing.
ET100% showed superiority over than ET85% and ET70% in improving sunflower yields and its attributes, but WUE did not affect.
Sunflower sown in May and irrigated with ET100 % gave the maximum values of seed yield and its attributes and WUE surpassing other interaction treatments.
In June, WUE value increased under severe water deficit i.e.
ET70% comparing to moderately water–stressed (ET85%) or well–watered conditions (ET100 %).
