Abstract :

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.‎
