Abstract
Soil fertility management systems (SFMS) can influence the community structure of arbuscular
mycorrhizal fungi (AMF). Hence, long-term SFMS was studied. The SFMS comprised three legume
combinations, urea application and solely maize as control. Spores were extracted by wet sieving,
characterized and identified using their morphology. Interrelationships between cropping systems
and occurrence of AMF species were analyzed with genotype by environment (GGE) biplot. Seventeen
species were identified with Glomus species (47.05%) having highest value while Gigaspora species
had the least (11.76%). Legume residues significantly (P < 0.05) increased spore population with
the highest spore count (120 spores/100 g soil) obtained in plot under cowpea residue. Shannon Weiner index (H
) of maize/Lablab purpureus plot was highest (1.996) while that of sole maize
system was the least (1.550). The GGE indicated Glomus intraradices as a stable species across all
the SFMS. Community structure of AMF and function can be preserved using appropriate SFMS.
