<![CDATA[Arbuscular mycorrhizal fungi (AMF) have been reported to increase yield and phosphorus (P) uptake. However, it is still unclear how the common bean responds to mycorrhizal inoculation when there is a phosphate supply. This research focused on finding out how bean performance will be affected by mycorrhizal inoculation and increasing P dosages in order to reduce phosphate input. The study was conducted during the A 2021 cropping season in Kabare, while a split-plot design was used to compare two levels of inoculation and increasing phosphorus doses. Rhizophagus irregularis inoculation significantly improved mycorrhizal colonization, biomass, yield, and harvest index of beans at 0 and 30 kg P ha-1. Bean plants inoculated with R. irregularis performed better in terms of biomass, yield, and harvest index at 30 kg P ha-1 than non-inoculated and inoculated plants at 60 and 120 kg P ha-1, indicating the potential of AMF in lowering phosphate input. Phosphorus levels of 60 and 120 kg P ha-1 significantly decreased mycorrhizal infection, indicating the impact of inorganic P on the mycorrhizal symbiosis. In the ferralitic soils of Kashusha, mycorrhizal inoculation with R. irregularis may be a key tool for increasing bean production and ensuring phosphate fertilizer savings.]]>
