The aim of this investigation was to isolate the most specific, effective and competitive strains for peanut, determine level variability in peanut cultivars response toward single/dual inoculation. Peanut seeds three namely 55–437, Fleur 11 69–101 were inoculated with two bradyrhizobial (LMG9283 USDA3187) an AM fungus Glomus intraradices, individually or combination, grown open–air conditions using a non–sterile sandy soil from Sangalkam. Plant controls supplied NPK chemical fertilizer at rate 150 300 kg ha–1. Results obtained term nodule occupancy revealed high competitiveness LMG9283 strain 55–437 69–101. However cultivar nodulated by indigenous rather than introduced strains. Assessment data on nodulation, shoot biomass pods yield that, among single inoculation cultivars, produced largest increase parameters studied, however, showed higher growth fertilization. dual associated with G. intraradices further improved studied 69–101, demonstrating synergy between and G. intraradices. This better allowed us suggest that should be tested arable fields with Bradyrhizobium strain and G. intraradices.
