Elucidating the diversity of native arbuscular mycorrhizal (AM) fungi is essential for sustainable management semi-arid land ecosystems. This because they significantly improve plant nutrient uptake and decrease stress caused by biotic abiotic factors. In this study, we examined AM fungal communities key drivers influencing their occurrence in smallholder farming systems Eastern Kenya. Soils samples were collected from 34 diverse agricultural fields spores extracted using wet-sieving decantation techniques. The quantified, identified based on morphological characteristics. Statistical data analyses, including relative abundance, Shannon-Wiener index, analysis variance (ANOVA), principal component (PCA), performed R software 4.4.0. results revealed that two families dominated fields, namely Gigasporaceae (61.0%) Acaulosporaceae (39.0%). These comprised a total five genera, with following abundances: Acaulospora (39.0%), Gigaspora (35.05%), Scutellospora (23.92%), Dentiscutata (1.32%), Rococetra (0.72%). morpho-species ranked 1 to 26 across genera. denticulata highest, proportion 25.19%. index higher greater spore richness. PCA showed composition was strongly related soil physiochemical Dryland also played role composition. Overall, distribution lower, implying need adopt dryland enhance support development context-specific biofertilizers.
