英文摘要	Injudicious application of chemical fertilizers in India has a considerable negative impact on economy and environmental sustainability. There is a growing need to turn back to nature or sustainable agents that promote evergreen agriculture. Potassium is important and well known constraint to crop production in India. In present investigation, K-solubilizing bacteria (KSB) were isolated from wheat growing area in different climatic conditions in India. A total 842 bacteria were isolated and 362 were found to solubilize potassium on Aleksandrov agar medium containing three different K-substrate including mica, potassium aluminosilicates and feldspar. Selected KSB isolates were characterized for other plant growth promoting (PGP) attributes such as solubilization of phosphorus and zinc, production of siderophore and IAA, ACC deaminase activity. Selected KSB were characterized employing 16S rDNA-Amplified Ribosomal DNA Restriction Analysis with three restriction endonucleases AluI, MspI and HaeIII, which led to formation of 16-28 groups for the different sites at 75% similarity index, adding up to 131 groups. Phylogenetic analysis based on 16S rRNA gene sequencing led to the identification of 131 bacteria grouped in four phyla, Proteobacteria (59%), Firmicutes (34%), Actinobacteria (5%) and Bacteroidetes (1%), and included 48 distinct species of 21 different genera: K-solubilizing PGP bacteria may have exploited as agricultural agent for wheat crop under different stresses condition, critical diseases and may have also been used in the amelioration of K-deficient soils.
