Abundance and diversity of arbuscular mycorrhizal gungal (AMF) spores isolated from the rhizosphere of papaya and other different cropping systems in Central Kenya

Arbuscular mycorrhiza fungi (AMF), obligate symbionts, are important in the majority of cultivated plant species colonizing roots and supporting growth adverse climatic conditions. However, abundance quality mycorrhizal colonization is affected by land-use types, cropping systems climate change. On other hand, rhizospheric mycorrhizae present soils can be isolated for enhancing performance. One such opportunity arises acclimatization seedlings adaptation to depleted field Isolation characterization AMF evaluating efficiency especially plants that have not been previously evaluated as papaya, which well known its high nutritive value. In this study, were sampled from grass, banana papaya plants’rhizosphere, three different growing regions Kenya; Mwea, Mitunguu Juja. Spores using sucrose method. Spore was done a gridded Petri dish morphologically characterized International Culture Collection Vesicular Mycorrhizal Fungi (INVAM) database. At least 4 families, 10 genera 41 glomeromycota phylum 3 sampling sites. The families glomeraceae (16 species) acaulosporaceae (14 dominated Juja Mwea Sub Counties. Glomus spp. rhizosphere grass most abundant, at p≤0.05, while Diversispora spp (diversisporaceae) p≤0.05. County had spore abundance, compared spores family (Mwea, 41; Juja, 37; Mitunguu, 35.2) opposed plants. results showed diversity varies with locations associating
