Increasing seed germination and enhance seedling growth with expensing less time, cost and effort is vital for supply growing edible oil demand, in Iran. This experiment was carried out using a split plot layout in a randomized complete block design with three replications during 2013 growing season. The main factor was seed priming with various nano-sliver particle concentration including 4 levels of 0 (distilled water: control), 20, 40 and 60 ppm, the sub factor was saffl ower cultivars with 3 levels included: Sina’, Faraman’ and IL111’. Results showed that the effects of nano-silver on growth traits including: stem dry mass, leaf dry mass, head dry mass, seed weight in head and numbers of head in plant were signifi cant and the highest value of mentioned characters were achieved at 20 ppm nano-silver. The comparison of seed weight in head in various nano-silver particles treatments with control showed that the highest seed weight in head was obtained at 20 ppm nano-silver as it produced 63.18% more yield in comparison to control.
