Abstract. This study was conducted in an experimental field in a randomized complete block with three replications in Urmia, West-Azarbayjan province of Iran. Foliar application nano Fe3O4 was performed at 3 stages of corn growth, knee stage, vegetative growth and grain filling. Corn seeds after harvested, were soaked and then germinated and dried. Iron content and phytase activity were determined. The results of this study revealed that foliar application of nano Fe3O4 significantly induced iron concentration and the activity of phytase (P<0.01). The results of this study showed that nano iron oxide fertilizers enhances the quality of corn seeds by decreasing phytate content and increasing Iron concentrations.
