A field experiment was carried out at the Al-Shafeieyah Wheat Research Station of the National Program for Wheat Development in Iraq (NPWD) to study the response of wheat to foliar application of nano- micro nutrient (Iron, zinc and copper) as single (mono) or in combinations. The experiment included application of nano-iron, nano-zinc, nano-copper and traditional sources of (iron + copper + zinc) and without application as control for comparison. Number of plant and yield (quality and quantity) parameters were recorded. Results indicated that significant response was combined nano- (Fe+Cu+Zn) followed by the treatments of di and single spraying compared to control treatment with an increment of the triple foliar of 27.47, 28.53,18.22,141.23, 33.33 and 57.40 % for plant height, length of spike, total chlorophyll SPAD, concentration of Cu, Zn and Fe ,respectively compared to control treatment. The same treatment (tri) had grain yield and protein yield of 5.84 t ha-1 and 830.44 kg ha-1 compared to the treatment of triple of traditional fertilizers and control, Which amounted to (4.55 and 3.60 t ha-1) and (571.48 and 443.88 kg ha-1) ,respectively. Harvest index were 51.05, 46.85, 48.73, 48.84, 40.57, 40.95, 43.71 and 37.89% for tri, di, single, control (Cu + Zn + Fe, Zn + Cu, Zn + Fe, Cu + Fe, Fe, Zn, Cu and control, respectively).
