Abstract: The present investigation entitled “Morpho-biochemical characterization and mica-K solubilization capacity of bacterial K-solubilizers in vitro” involved a laboratory experiment conducted at Soil Biology Laboratory, Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, U.P. (India). The bacterial isolates were selected based on their morphological and biochemical characteristics. The selected efficient isolates were further examined for their ability to solubilize potassium from insoluble K source. All the isolates were gram +ve, rods, motile. Colony color ranged from hyaline to creamy with smooth margin and elevated colony except isolate KSB 64 which was non-motile and forms rough flat colony. KSB 38 showed its significant superiority over rest of the isolates in forming zone of solubilization.
