An experiment was conducted at Field of Crop Production Sciences-College of Agriculture, Baghdad University, to study the effect of spraying concentrations of iron and zinc as sulfates on some vegetative properties and grain yield of wheat (Dor 29 variety).

N, P and K fertilizer were added.

Iron sulfate and Zinc sulfate were sprayed the concentrations of (0, 50 and 100) mg.

Fe and (0, 50 and 100) mg Zn.

L-1 at three stages of plant growth (vegetative growth, boating and flowering stages).

Randomized complete block design was used at three replicates.

Results showed that : All concentrations of iron , zinc and their interactions affected significantly on all study parameters .

Interaction treatment Fe2 x Zn2 had a high effect on all parameters which were plant height (115.7) cm, flag leaf area (39.1) cm2, chlorophyll index (51.5) spad unit, No.

of tillers (8) tillers and grain yield (5.33) t.ha-1.
