Abstract

Abstract:
Background &Objective: The use of organic fertilizers such as vermicompost, mushroom waste compost and also biological fertilizers in the organic production of medicinal plants, in addition to providing part of the nutrients needed by the plant, also prevents soil pollution. Therefore, this research was carried out with the aim of evaluating the effect of organic culture medium and seaweed on growth indicators, yield and essential oil of savory plant (Satureja hortensis L.).

Materials & Methods: This factorial experiment was carried out in the form of a completely randomized design with 3 replications in the Horticultural Science Greenhouse of Mohaghegh Ardabili University. The experimental treatments of the substrate included soil with a ratio of 1:2 soil and sand as a control, and the replacement ratios were 30% of vermicompost and 30% of spent mushroom compost, and other treatments included foliar spraying with seaweed extract at four levels. 0, 0.5, 1 and 2 g/L) in another experiment

Results: The results of the experiment showed that the effect of organic and biological fertilizers on vegetative growth indicators and qualitative traits was significant compared to the control. The highest value for physiological traits and content of phosphorus, nitrogen and most essential oil compounds was related to vermicompost bed and the lowest value of these traits was related to the control treatment. The most phosphorus (4417 mg/kg), nitrogen (3.93 %) was obtained for foliar spraying with a concentration (0.5 g/liter) of seaweed and vermicompost bed,
