In order to evaluate the effects of organic and chemical fertilizers and mycorrhizal inoculation on seed yield and oil percentage of common dill (Anethum geraveolens L), an experiment was conducted as factorial based on randomized complete block design with three replications at Research Farm of Ferdowsi University of Mashhad in 2013 growing season. Fertilizer resources (cow manure, vermicompost, chemical and control) and mycorrhizal inoculation (Glomus mosseae, G. intraradices and lack of inoculation) were the first and second factors, respectively. Based on analysis of variance, effects of mycorrhiza and fertilizer application on all of the studied treatments of common dill were significant. Seed and biological yields and seed weight per plant were increased significantly as the result of application of cow manure, vermicompost and mycorrhizal inoculation; so that vermicompost application increased seed yield, biological yield and seed weight per plant by 41, 45 and 50%, as compared to control treatment. In addition, application of cow manure and mycorrhizal inoculation increased significantly the oil percentage to 10 and 5 percent and oil yield to 16 and 54 percent, in comparison with control treatment.
