Abstract:
In order to study the effects of fungal growth and amount of vermicompost on yield components herb Echinacea purpurea, a pot experiment was conducted in a research station of mazandaran province(amol) during 2014 growsing season. The experimental treatments were arranged as split plots based on a randomized complete block design with three replications. Factors in this study were including fungal growth(Glomus intraradices and Gigaspora margarita, combinations of two fungi and control) and amount of vermicompost (0%,25%,50%,75%,100%),The results showed that use of fungal tretments and amounts of vermicompot were significant at 1% on traits of herb height, canopy size,flower diameter,shoot fresh and dry weight, root length and specific root weight of herb Echinacea purpurea. Use of combinations of mycorizal fungi and vermicompost was significant at 1% on specific root weight and was significant at 5% on root fresh and dry weight. Use of amounts of vermicompot were non-significant on root fresh and dry weight and root volume. The highest root length(43/68 cm) was observed in control treatment (without use of vermicompost) and the shortest root length (31/84cm) was observed in treatment of 75%vermicompost.The highest shoot dry weight(12/79 gr) was obtained by combinations of two fungi and the fewest shoot dry weight(9/26 gr) was obtained in control treatment,wthout use of fungi. The highest root volume (60/27 cm3) was obtained by applying 25%vermiccompost and without use of fungi. and the fewest root volume (24/75 cm3) was obtained by applying Glomus intraradices and 75% vermicompost. The highest shoot fresh and dry weight and root fresh and dry weight and specific root weight were obtained by applying combinations of two fungi and 75-100% vermicompost. finally use of combinations of two fungi and 100%vermiopost has been abled to improve 45% herb hight than control herb.
