Abstract

In order to study the effects of applying chemical and biofertilizers on some quantitative andqualitative characteristics of Dracocephalum kotschyi Bioss., a factorial CRD experimentincluding 18 treatments with 4 replications, was conducted at Imam Khomeini InternationalUniversity research greenhouse. The treatments were: Vermicompost (0, 10 and 20 V/V), phosphate biofertilizer (application and no-application) and chemical fertilizer (0, 50 and 100%of the recommended amount equal to 0, 0. 48 and 0. 96 gr/pot respectively). The Essential oil wasextracted by hydro distilation method by using a clevenger apparatus and were analyzed by GCand GC/MS. Results were showed that the maximum plant height, number of branches perplant, number of inflorescences per plant, fresh and dry weight and the highest percentage ofessential oil were obtained as a result of using 20% Vermicompost. Plants treated by 50% ofrecommended NPK+20% Vermicompost showed the highest rate of photosynthesis andtranspiration. The maximum nitrogen concentration in leaf tissue was obtained from applying100% of the recommended amount of NPK+Biophosphate. Applying 100% recommendedNPK+20% Vermicompost, resulted in higher phosphorus concentration in leaves. The highestconcentration of potassium in leaves was obtained from plants treated with 20% Vermicompost. 26 different compounds were identified in the Essential oil among them Limonene and verbenonewere the main components. The highest amounts of these two compounds were obtained under20% Vermicompost treatment. According to the results Vermicompost is an efficient substitutefor chemical fertilizers in production of D. kotschyi.
