A glasshouse experiment was conducted to screen and select the efficient AM fungi for inoculating two drought susceptible soybean cultivars MAUS 2 and MAUS 212. Screening was done using 10 different species of AM fungi. Plant parameters like plant height, stem diameter, biovolume index, total leaf area, dry biomass, P concentration, and mycorrhizal parameters like root colonization, spore number in the root zone soil were recorded according to the standard procedures. Based on the improvement in plant parameters like biovolume index, total leaf area, shoot and root dry biomass, plant P uptake, pod and seed yield, it was concluded that Ambispora leptoticha was the best AM fungus for inoculating both the cultivars MAUS 2 and MAUS 212.
