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. date: 2022-10-22 date_type: published publication: 3 Biotech (TSI) volume: 12 number: 318 publisher: Springer pagerange: 1-11 refereed: TRUE issn: 2190-5738 official_url: https://doi.org/10.1007/s13205-022-03389-8 related_url_url: https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=doi.org%2F10.1007%2Fs13205-022-03389-8&btnG= related_url_type: pub citation: Gopalakrishnan, S and Srinivas, V and Chand, U and Pratyusha, S and Samineni, S (2022) Streptomyces consortia‑mediated plant growth‑promotion and yield performance in chickpea. 3 Biotech (TSI), 12 (318). pp. 1-11.
