Agave cantula is an essential plant for decreasing soil erosion and withstanding drought. In this paper, we discuss about the possible impact of symbiosis between mycorrhizae and Agave cantula seedlings, especially their accelerated growth, biomass and photosynthetic pigments in nursery conditions. Furthermore, we delineate the process of mycorrhizal spore isolation from soil and also the adaptability of plants in conjunction with Arbuscular Mycorrhizal fungi. In order to study this impact, the plants were grown in arsenic amended pot soil under the Four levels of arsenic (0, 25, 50 and 100 mg/kg soil) and three mycorrhizal treatments (Glomus fasciculatum, Glomus macrocarpum and non-mycorrhizal) with five Replications. Mycorrhizal colonization significantly increased the root length, shoot height, collar diameter and number of leaves for maximum 4.28cm, 4.92cm, 0.97mm and 9.8 sequentially. The results showed that biomass of seedlings was enhanced by Arbuscular Mycorrhizal symbiosis compared to non-mycorrhizal seedlings which was 0.23gm for Root and 0.449 gm for Shoot. The phenomena of root nodules formation due to Arbuscular Mycorrhizal symbiosis were not observed in Agave cantula seedlings. This study also symbolizes that this symbiosis might have great potential for soil conservation and ecological restoration.
