Composition and spore abundance of arbuscular mycorrhizal fungi in sweet potato producing areas in Uganda

Introduction Farming systems influence composition and abundance of microbial communities. Methodology A study was conducted using morphotyping enumeration methods to determine the spore Arbuscular Mycorrhizal Fungi (AMF) in sweet potato producing regions eastern Uganda. Sampling done from fields with crop types (CTs) including legumes (groundnuts, common beans, cowpea, soybeans, green grams), sorghum, potato, fallowed which were used as a control. Three agro-ecological zones (AEZs) i.e., Mt. Elgon High Farmlands (MEHF), Lake Victoria Crescent (LVC), Southern Eastern Kyoga Basin (SELKB) considered. Results discussion total 6 AMF genera comprising Glomus, Acaulospora , Scutellospora, Entrophospora, Archaeospora, Gigaspora isolated sites. Agro-ecological had significant (p<0.05) effect on Entrophospora spp. while although all present AEZs CTs. Spore similar across except for MEHF (177) lower lowest largest fallow (224), attributed soil properties crops included rotation program. The can be isolated, identified, multiplied produce bioinoculants regions.
