Abstract: Iron (Fe) is one of the essential elements for plant growth and plays an important role in the photosynthetic reactions. The purpose of this study was to evaluate the effects of different concentrations and different application times of Nano-Fe fertilizer on quantitative and qualitative aspects of wheat. A field experiment was carried out at the Research Center Research for Agriculture and Natural Resources of Sabzevar, northeastern Iran, during 2011-2012 to evaluate the effect of concentration and time of application of Nano-Fe on wheat (Triticum aestivum) yield and yield components with a factorial arrangement of treatments in a randomized complete block design with 3 replicates. Treatments consisted of 3 application times (tillering, stem elongation and tillering+stem elongation) and 4 Nano-Fe application rates (spraying with concentrations of 0, 2‰, 4‰ and 6 ‰ as corresponding with 0, 2, 4 and 6 kg Fe ha -1 water-soluble Fe (Nano_Fe Chelates). Nano_Fe Chelates used in this study contained 9% Fe, 1% Zn and 1% Mn without ethylene compounds from Khazra Company. Results revealed that the time of application had a significant effect on tillers number, seeds per spike, grain yield, biological yield and thousand grains weight. Foliar application of Fe at tillering+stem elongation and at tillering had 9.17% and 5.19% more grain yield, respectively, compared to foliar application of Fe at stem elongation. Increasing Nano-Fe concentration, increased wheat yield and yield components. In this study, spraying with concentrations of 4‰ produced maximum grain yield, with no significant differences found between 4‰ and 6‰ concentrations.. Foliar application of Fe at 2‰, 4‰ and 6‰ produced an increase of 12%, 22.09% and 19.07% grain yield, respectively, over the control.
