To study the effect of different concentrations of Fe-foliar on the biochemical characteristics of sunflower under water stress, an experiment was conducted in Varamin in the agricultural year of 2013. The experiment was conducted as split plot in completely randomized block design with three replications. Main plot included three irrigation levels (normal irrigation, irrigation stop at flowering stage (8 leaves) and irrigation stop at grain filling stage (8 leaves and 16 leaves)) and sub-plot included three levels of Fe-foliar (pure water foliar, Fe-foliar once, Fefoliar twice). stopping irrigation at different growth stages increased the amount of antioxidant enzymes. Also, Fefoliar increased the antioxidant enzymes.
