In order to study the effect of biofertilizer on essential oil content and yield of Pot marigold (Calendula officinalis L.), an experiment was conducted as randomized complete block design with 6 treatments and three replications at research field of Islamic Azad University (Shahr-e-Ray branch) of Iran in 2012. The treatments were nitroxin, super nitro plus, mycorrhizae, animal manure, chemical fertilizer (NPK) and control (no fertilizer). Results showed that biofertilizer had significant effects on studied characteristics. 42 components have been detected in the essential oil of C.officinalis representing 94.3% of the total oil. The results have indicated that 29 constituents were affected by the application of biofertilizer. The highest essential oil content and essential oil yield were obtained by using the biofertilizer.
