Abstract

Sunflower (Helianthus annus L.) is the most important oilseed crop in Iran. This study evaluated the effects of soil application levels of zinc on SUNFLOWER yield and yield components under drought stress conditions. This experiment was conducted as split plot design based randomized complete block design at Sabzevar Agricultural Research Station in 2010-2011. Experimental factors were: Irrigation regimes in three levels (50, 100 and 150 mm evaporation from class A pan) as main plots and four fertilizer treatments of Zn (Control, 30 kg/ha, 60 kg/ha, 90 kg/ha) as subplots. The results showed that, IRRIGATION INTERVAL did not show significant effect on plant height and oil percent. Head diameter, seed number per head, seed weight, biological and seed yield was affected by IRRIGATION INTERVAL. The results indicated that, increasing IRRIGATION INTERVALs decreased head diameter, seed number per head, seed weight, biological yield and seed yield significantly. The maximum amounts of these traits were obtained in 50 mm IRRIGATION INTERVAL. 90 Kg/ha Zn application had the maximum value for all characteristics that did not have significant difference with 60 kg/ha Zn application. Increased Zn levels were reduced the effects of drought in SUNFLOWER. Drought stress effects wre decreased in higher Zn levels consumption. Although increasing IRRIGATION INTERVALs were decreased yield and yield components but this reduction was less than control for treatments that received Zn. Overall, In both stress and non stress conditions, 60 Kg/ha Zn application as ZINC SULFATE was recommended in order to achieve acceptable yield in SUNFLOWER.
