The relationships between multi-traits beneficial bacteria and their inoculations and Arachis hypogaea L. have been poorly explored, despite they dominate in the peanut’s rhizosphere and support plant growth, yield, nutrient uptake, and soil fertility. Inoculation with multi-traits beneficial bacteria promotes plant growth, yield and nutrient uptake. The present study assessed possible effects of mineral fertilizer (NP and P), two commercial liquid bio-fertilizer and IAA-producing, ACC deaminase-containing, N2-fixing, and P-solubilizing bacteria based bio-fertilizers in single (Pseudomonas fluorescens RC512, Bacillus subtilis RC210, Bacillus megaterium RC16), dual (RC210+RC16, RC512+RC210, RC512+RC16) and triple strains combinations (RC512+RC210+RC16) on nodulation and growth parameters of peanut. Inoculations of peanut with RC512, RC210, RC16, RC210+RC16, RC512+RC210, RC512+RC16, and RC512+RC210+RC16 gave increases over control respectively of by 10.9, 11.4, 5.3, 7.4,14.6, 7.2, and 21.9 % in dry weight of root, by 7.8, 3.0, 4.0, 9.5, 15.5, 9.0, and 23.6 % in dry weight of shoot, by 21.9, 10.1, 13.6, 20.4, 27.5, 20.0, and 28.7 % in number of nodules per plants, by 16.1, 8.6, 7.3, 13.8, 25.7, 8.6, and 27.9% in weight of nodules and by 18.3, 11.0, 8.8, 13.6, 16.4, 18.2, and 24.3 % in N content of shoot per plants. NP applications, however, increased dry weight of root up to 20.3%, dry weight of shoot by 27.1 %, number of nodules by 23.6%, weight of nodules per plants by 26.1% and N content of shoot by 26.2%. In general, triple inoculations performed better than uninoculated control, single and dual inoculations in terms of growth and nodulation parameters.
