A Split plot experiment based on randomized complete block design (RCBD) with three replications was conducted in 2012,Treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (Sardari, Rijav, Biseton and Rashid) as the second factor. Plant characteristics such as plant height, length of the peduncle, length of stamen, diameter of node, the number of node, and spike of length Fe and leaf area index were considered. Results showed that the time of Fe foliar application had a significant effect on studying traits. With respect to Duncan's Multiple Range test, mean comparison results revealed that the Fe foliar application at tillering stage and treatment control (no application) had the greatest and the least effect on traits respectively. Also there was significantly different among cultivars, as among cultivars the maximum and minimum mean of traits was obtained for Rijav and Rashid respectively. The interaction of foliar application × cultivar for plant height and leaf area index was also significant. Highest the wheat height and LAI were observed at foliar application in tillering with Rijav cultivar and the lowest means to control with the Rashid it can be concluded that the most suitable application of Fe solution for improvement morphological and physiological properties of different dry land wheat cultivars (in the same climate condition) was tillering stage, since more impression of Fe was observed in early growth stages
