To evaluate the effect of organic fertilizers and mycorrhizal symbiosis on yield components and percentage of essence of <em>Mentha aquatica</em>, a factorial experiment based on a randomized complete block design with 8 treatments and 4 replications was conducted in Sari, in 2014. The experimental treatments were mycorrhizal fuangi (<em>Glomus mosseae</em>) with two levels (0 and 10% per pot), vermi-compost with two levels (0 and 10% per pot) and compost of tea with two levels (0 and 1.5 liter per pot). The results showed that use of organic fertilizer and mycorrhizal symbiosis significantly improved the quantity and quality characters<em> Mentha aquatica</em>. Use of organic and biological fertilizers had a significant effect on most of the measured traits and increased all of the traits as compared to those of control. Thus, highest plant height, leaf number, seed number per plant, plant dry weight, root length, root diameter, leaf area index, essence present and essence yield were obtained by using mycorrhizal symbiosis and compost tea, vermin-compost as compared to those of control treatment. Generally, the use of organic and biofertilizers, produced optimum quality and quantity of <em>Mentha aquatica</em>. In fact, increased performance of organic and biological fertilizers improved the activity of plant growth regulators and reduced elemental leaching and thus resulted in higher absorption of nutrients, increased plant growth, seed yield and essential oil content of <em>Mentha aquatica. </em>
