Abstract

Currently trend to organic agriculture and uses of organic products is increasing. In order to investigation the effects of organic fertilizers of spent mushroom compost and vermicompost and seaweed and trichoderma fungi inoculation on growth indices، yield and secondary metabolites of Sovary (Satureja hortensis L.) two factorial experiment based on completely randomized design with three replications was carried out at Mohaghegh Ardebili University at 2016. In both experiment treatments including organic matter (soil with a ratio of 1: 2 soil and sand as control) and replacement ratios of 30% of vermicompost and spent mushroom compostas one factor and Trichoderma fungi inoculation and foliar spraying of seaweed extract in four levels (0، 1، 1.5 and 2 g per liter) were another factor in these experiments.. The results of both experiment showed that the effect of organic and biofertilizers on vegetative growth indices and qualitative traits were significant. The highest plant height, number of lateral branches, lateral branch length, leaf area, vegetation index, dry weight, zinc, phosphorus, nitrogen, and most essential oil compounds were obtained by vermicompost, and the least amount of these traits was related to control. In the first experiment the highest plant height, number of lateral branches, leaf area, dry weight, zinc, and some essential oil components were obtained for inoculation treatment with Trichoderma fungus and the least amount of these traits were obtained in control treatment. The highest vegetation index, leaf area, nitrogen and combination of sabinen and carvacrole related to the concentration of half a gram and the highest amount of plant height, number of lateral branches and most essential oil compounds were related to the concentration of 1 g/l and the most number of lateral branches, calcium, nitrogen and camphen compounds, beta . Bisabolene, Delta. 3. Kern and Thymol were the concentration of 2 g/l of seaweed treatments. In the interaction of organic substrate and Trichoderma fungi, for most of the indices, the vermicompost was inoculated with the highest amount, and after that, the bedding of the inoculated mushroom compost residue had a positive effect on the indices. In the interaction of s bed and seaweed, the highest amount of Vermicompost substrate was sprayed with 1 g/l algae, followed by 1 g/l of mushroom compost. Which had the least amount of interaction in the treatment of both treatments. Comparisons between treatments showed that the use of organic Vermicompost and Trichoderma fungi, and then mushroom and seaweed compost were better. In the case of seaweed, 1 g/l concentration The rest increased the amount in the factors and the concentration of 2 g/l in many cases was negative
