Description Fourteen Streptomyces strains reported earlier as plant growth promoters (PGP) in chickpea were characterized for production
of ammonia and 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase and solubilization of silica and zinc. The
results showed that nine (CAI-17, CAI-78, KAI-26, CAI-21, CAI-26, MMA-32, CAI-140, CAI-155 and KAI-180) and six
(CAI-17, CAI-21, CAI-26, CAI-13, CAI-93 and KAI-180) strains were found to produce ammonia and ACC deaminase,
respectively, while one (KAI-180) and eight (CAI-17, CAI-21, CAI-26, MMA-32, CAI-13, CAI-85, CAI-93 and KAI-180)
strains solubilized silica and zinc, respectively. The selected 14 Streptomyces strains were categorized into three consortia
groups, consortium-1 (CAI-17, CAI-68, CAI-78, KAI-26 and KAI-27), consortium-2 (CAI-21, CAI-26 and MMA-32) and
consortium-3 (CAI-13, CAI-85, CAI-93, CAI-140, CAI-155 and KAI-180), based on their compatibility, and evaluated for
their PGP traits in chickpea. The experiment was conducted under field conditions with two chickpea varieties over two
years. The consortia-treated plots enhanced nodule number up to 23%, nodule weight up to 36%, root weight up to 27% and
shoot weight up to 26% at 30 days after sowing and pod weight up to 35%, pod number up to 34% and grain yield up to 24%
at harvest over the un-inoculated control plots. The harvested grains of consortia treatments were found to enhance crude
protein up to 14%, crude fibre up to 17% and crude fat up to 16% over the grains from un-inoculated control. The rhizosphere
soils of the consortia-treated plots enhanced total nitrogen up to 21%, organic carbon up to 8% and available phosphorous
up to 16% over the un-inoculated control plots. This investigation demonstrated the potential use of the selected consortium
of Streptomyces strains in the farmers’ fields to improve the chickpea yields and soil fertility.
