Potassium is a vital mineral and the second most important macronutrient required by the majority of crops. Potassium sources in soil are ample but most of it being insoluble is unavailable for plant uptake. Potassium deficiency results in poor plant growth and development which eventually reduces crop output. Microorganisms have the capability to release soluble potassium from potassium-bearing minerals, therefore making the unavailable potassium available to the plants in soluble form. For this investigation, rhizosphere soil samples from the Rice crop were gathered from 15 different locations at Veeranam command area in Cuddalore district, Tamil Nadu. The isolated potassium solubilizing bacteria in rice rhizosphere (KSBR) were tested for their ability to solubilize the insoluble source of potassium (Mica). Mica was used as an insoluble potassium source. The isolates were identified based on morphological and biochemical characteristics. The solubilization zone for potassium ranges from 0.23 to 1.29 cm in diameter. The isolate, KSBR-12 had the maximum solubilization zone at 72 hours after incubation, measuring 1.29 cm in diameter. Also, the strain (KSBR-12) released the highest level of potassium (40.12 µg/ml of broth) at 21 days after incubation in broth containing Mica.
