Effect of Different Water Stress Levels on Yield and Oil Content of Sunflower (Helianthus annuus L.) Cultivars

Ameer Khan, Muhammad Iqbal, Iftikhar Ahmad, Naeem Iqbal and Mumtaz Hussain    

Abstract: A decreasing trend in head diameter, number of achenes per head, hundred achene weight and achene yield per plant to as observed as the level of water stress increased from 100 percent to 25 percent of field capacity. Seed oil content was very sensitive to even mild water stress but showed stability under increasing stress conditions. FH-1 responded better at high level of water stress in respect of all the parameters studied except for hundred achene weight, where FH-3 showed better response.
