In order to study the effect of mycorrhizal fungi and compost on some of the growth characteristics of lawn (Ray grass/Perennial ryegrass) a greenhouse experiment was conducted in factorial in completely randomized design with 3 replications at Plant Productions Center, Mashhad Municipality, during cropping season 2015-2016, Mashhad, Iran. The factors were included five levels of compost (0, 1, 3, 5, and 7 Wt% flower pot soil) and two species of mycorrhizal fungi in four levels (Without application (Control), Glomus intaradices, Glomus mosseae and Glomus intaradices + Glomus mosseae). The result of variance analysis showed that the effect of compost on all traits, and mycorrhizal fungi on leaf length, root length, root fresh and dry weight, root length / shoot length and chlorophyll content were significant. However the effect of interaction between the two factors on traits was not significant. Based on mean comparison of traits, the highest amount of all traits (Expect: root length/shoot length) were obtained by 5% compost. The highest amount of root length/shoot length obtained by 7% compost. The most root length, root fresh and dry weight and root length/shoot length were influenced by Glomus intaradices + Glomus mosseae application. Overall, the results of this study showed positive effect of the application of compost on all traits and mycorrhizal fungi on root growth characteristics of lawn.
