To explore plant growth promoting abilities of native rhizospheric potash mobilizing bacterial (KMB) consortium with/without graded doses of potash in maize. A liquid potash mobilizing PGPR consortium was developed and its efficacy on maize was ascertained through field experiments at Main Maize Research Station, Godhra, Panchmahals, India during two consecutive seasons kharif and rabi in Randomized Block Design (factorial) with three replications. Based on PGP traits and tolerance tests five selected Acinetobacter potash mobilizing PGPR strains were screened for compatibility with each other showing high viable cell count in GYC broth. Overall results obtained from the field experimentation, it is concluded that the highest yield and yield attributing parameters of maize were recorded in treatment receiving KMB consortium @ 5 ml/kg seed along with soil application of 100% recommended dose of potash fertilizer (RDFK). The treatment receiving KMB consortium @ 5 ml/kg seed along with 75% RDFK was found at par with 100% RDFK suggesting possible saving of 25% RDFK. An innovative potash mobilizing PGPR consortium based on Acinetobacter strains developed and when applied @ 5ml/kg seed along with potash fertilizers enhanced growth and yield of maize - a promising life sustaining food and fodder crop
