This research was conducted in order to evaluation of bio–fertilizer Nitroxin, Super–nitro plus, Bio–sulfur and urea fertilizer (NH22CO) in randomized completely block design (RCBD). This trial included of 9 treatments and 3 replications. Data of this experiment analyzed using SPSS software and means comparison studied according to Duncan test.Bio–fertilizers including bio–fertilizer Nitroxin, Super–nitro plus and Bio–sulfur each one in 4 and 8 kg\ha, urea fertilizer in 75 and 100 kg\ha and control treatment (without using urea fertilizer and bio–fertilizer). The results showed that according to results obtained from variance analysis in Lemon balm medicinal plant found that effect of soil fertilizers including bio–fertilizers (Nitroxin, Super–nitro plus, Bio–sulfur) and urea fertilizer on traits such as plant height, number of stems per plant, fresh weight of stem in plant, dry weight of stem in plant, fresh weight of root in plant, dry weight of root in plant, leaves number per plant, fresh weight of leaves per plant, dry weight of leaves in plant, fresh weight of shoot in plant, essential oil percent, essential oil yield and dry biological yield in 1% level of probability was significant. This trial showed that bio–fertilizers (Nitroxin, Super–nitro plus and Bio–sulfur) could partly compensate the decline in biological yield and essential oil yield resulted from nutrients deficiency caused by not using of fertilizers thus application of these bio–fertilizers (Nitroxin, Super–nitro plus and Bio–sulfur) alone or with less amounts of chemical fertilizer is recommended.<\div>
