Abstract :

Sunflower is one of the most important oilseeds in the world, because of the high quality of oil it is important to plant. In order to investigate the effect of three factors of water stress, magnetic pretreatment and aqueous pretreatment on yield and yield components of experimental sunflower, a factorial experiment was conducted in which water stress as the main factor and two other pretreatments as factorial. The sub factor was evaluated. The results showed that in this experiment none of the main effects and interactions had any effect on grain yield. Grain yield was affected by the interaction between water stress and magnet pretreatment and triple interaction effects. The highest grain yield was in full irrigation treatment, 150 mT magnet pretreatment for 30 min and water pretreatment. The effect of stress on the harvest index based on oil yield as well as the interaction of stress on magnetism was significant.
