The chemical fertilizers have harmful impact on the environment and decrease the quality of the agricultural products. This study was carried out in order to compare biological fertilizer type phosphate solubilizing bacterium (Barvar2) and nitrogen fixing bacterium (Nitroxen) and chemical fertilizer. The effects of biological and chemical fertilizers and mixtures of them were analyzed by using a complete random blocks design (CRD) with three replications during 2009 -2011 in Arak. The effect of treatments were significant on certain characteristics such as plant height, number of branches, plant dry weight, biomass, essence percent, essence yield, LAI. Between the treatments N150P120K150 with an average 9.314 kg ha-1 had highest essential oil yield and Barvar2+Nitroxen+ N50P40K50 with age 3469.51 kg ha-1 had highest biomass.
