In this experiments were carried out to isolation of mycorrhiza from roots and spore population from rihzosphere in five species of angiosperms and to investigate the effect of mycorrhiza fertilizer on the yield of Capsicum annuum L.(pepper) in Magway University during January to December 2017. These experiments included laboratory, pot were conducted at Magway University. In laboratory experiment mycorrhiza colonization of roots were calculated by grid-line intersection method and spore population were collected by spore decanting method. The highest colonization was observed in roots of Allium cepa L. (63.4%) and the Lowest colonization was occurred in Andrographis paniculata Nees. (22.10 %). Highest number of spore was observed in rhizosphere of Zea mays L.. (42). and lowest number of spore was observed in root of Cleome gynandra L. ( 28 ). In pot experiment, the effect of mycorrhiza infected roots on yield of pepper were also investigated. These results also indicated that yield parameter of the earliest day to flowering and fruiting was found in treated with VAM , and the latest was observed in the control. The yield component of pepper weight were obviously increased the effect of treated with VAM, than control at harvested time. According to result suggested that, the use of mycorrhiza had a higher positive effect of yield on Capsicum annuum L.(pepper)
