We conducted field experiments in two locations to investigation of organic and chemical fertilizer on soil characteristics and essential oil yield in dragonhead. Results showed that the inoculation of bacteria with the seeds in location 1 and also the inoculation of bacteria with the seeds of G ₁ genotype in location 2 than G ₂ genotype increased the total soil nitrogen content. The application of azocompost and its inoculation with urea's chemical fertilizer comparing to chemical control, it increase the soil carbon content. Results indicated that by increasing azocompost content with a linear procedure bulk density increased. Results showed that application of 100% azocompost treatment had the highest electrical conductivity in the soil. According to the results, the main effect of genotype and fertilizer regime and also two-way interaction (bacteria × fertilizer) had significant relationship with essential oil yield.
