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.
