Fertilizer management is one of the most important factors in successful cultivation of medicinal plants. Meanwhile, identification of eco-friendly and suitable fertilizers could have favorable effects on quantitative and qualitative indexes of plant. For this purpose, an experiment was conducted based on factorial in a completely randomized design with two factors, nanophosphorus for foliar application (0, 2 and 4 g.l-1) in three stages and vermicompost (0, 5 and 10 percent by weight of pot soil), in Sari Agricultural Sciences and Natural Resources University with three replications in 2014. Results indicated that all traits such as number of flower per plant, fresh and dry flower yield, essential oil percentage, essential oil yield and kamauzolen percentage were affected by different fertilizer treatments. The highest number of flower per plant, fresh and dry flower yield and essential oil yield was obtained using 2 g.l-1 nanophosphorus + 10 percent vermicompost and the lowest amount was belonged to control. The maximum essential oil percentage (4.46 percent) was obtained by applying the highest levels of fertilizer (4 g.l-1 nanophosphorus + 10 percent vermicompost) that increased 43 percent compared to the control. Also, kamauzolen percentage was the highest amount in control (15.9 percent) which positioned in the same statistical level with 2 g.l-1 nanophosphorus + 5 percent vermicompost (15.43 percent).
