Pearl millet ( Pennisetum glaucum ), a staple cereal in the Sahel, faces severe yield limitations due to sandy, nutrient-poor soils and erratic rainfall. Sustainable fertilization strategies that enhance nutrient use efficiency are urgently needed. This study evaluated the combined effects of arbuscular mycorrhizal fungi (AMF) inoculation and fertilizer microdosing on nutrient removal and agronomic efficiency in pearl millet grown in Sahelian sandy soil. A greenhouse experiment with nine treatments combining NPK, urea, cow manure, and AMF was conducted using soil pots arranged in a completely randomized design with five replicates. Nutrient removal (N, P, K, Ca, Mg, Cu, Mn, Fe, Ni) and shoot dry biomass were measured after 12 weeks, and agronomic efficiency (AE) was calculated for N, P, and K. Treatments significantly affected nutrient removal (p < 0.001). AMF alone enhanced micronutrient removal, particularly Mn (296 mg/kg) and Fe (550 mg/kg), while manure + AMF increased macronutrient removal (N ≈ 17 mg/kg, K ≈ 81 mg/kg). Moderate NPK microdosing with AMF achieved the highest AE values (AEN = 6.7 g/g; AEP = 15.8 g/g; AEK = 15.8 g/g). High-input treatments increased nutrient removal but reduced efficiency. This controlled environment study demonstrates that AMF-based microdosing is a promising strategy to improve nutrient efficiency in pearl millet grown on Sahelian sandy soils.
