This experiment was conducted in in Boin Zahra area, Qazvin at 2015-2016 in order to investigate the effect of spraying time and micronutrient elements on wheat traits in split plot as randomized complete block design with three replications. The time of spraying at stemming stage and spike emergence stage as main factor and the micronutrient elements in 8 levels: non-consumption (pure water), iron, zinc, copper, iron + zinc, iron + copper, copper + zinc and iron + copper + Zinc in sub plots. The results of analysis of variance showed that the effect of spraying time (at 5% level), micronutrient elements (at 1% level), and the interaction effect of spraying time × micronutrient elements (at 1% level) on grain yield was significant. The results of comparison of the effect of spray time on grain yield showed that spraying during spike emergence increased grain yield. Spraying at the time of emergence of spike with an average of 6789 kg/ha was significantly superior to stemming stage, and increased by about 5%. The results of the comparison of micronutrient effects on grain yield showed that the coagulation of iron + copper + zinc with the mean of 7483 kg/ha had the highest grain yield. The results of comparing the effects of spraying time and micronutrient on grain yield showed that iron + copper + zinc solution had the highest grain yield at spike time. The results also showed that spray application spray increased seed yield of each micronutrient treatment.
