Many efforts have been made to find suitable ways to improve the quality of soil and agricultural products, among which are biofertilizers and organic fertilizers. This study was performed to investigate the effect of mycorrhiza fungus, different levels of humic acid (0, 200, and 400 mg l-1) and salicylic acid (0, 100, and 200 mg l-1) on the growth indices, phytochemical characteristics and nutrient levels of Lemon balm (Melissa Officinalis L. cv Citronella) in a greenhouse in northern Iran. The experiment was performed in completely randomized design with 3 replications. The results showed that all treatments had a significant effect on the measured variables. The highest fresh and dry weight of shoot, phenol and flavonoid, nitrogen, phosphorous and potassium content were observed in M + HA 400 mg l-1 + SA 200 mg l-1 treatment and the highest Fresh and dry weight of shoot and root volume were obtained in M + HA 400 mg l-1 + SA 100 mg l-1 treatment. Also the maximum total chlorophyll content and essential oil yield was obtained in M + HA 200 mg l-1 + SA 200 mg l-1 treatment. In general, mycorrhizal fungus with humic acid 400 mg l-1 and salicylic acid 200 mg l-1 treatment is effective to improve vegetative growth, essential oil and nutrient uptake on lemon balm (Melissa Officinalis L. cv Citronella).
