Applying a microdose of NPK fertilizer to pearl millet in a greenhouse experiment increased chlorophyll content by 46% and collar diameter by 30% compared to untreated controls. Inoculation with arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR), alone or combined, produced more variable effects; shoot biomass improved up to 20%, but root biomass showed no significant change (1.02% increase). A site effect was observed: growth at Touba Toul was about 60% higher than at Gossas. Combining biofertilization with fertilizer microdosing may offer a sustainable strategy for pearl millet production in the Sahel.
