Microbial isolates were collected from rhizospheric soil of Meerut-Muzaffarnagar district of western Uttar Pradesh to identify the potassium solubilizing efficiency of different soil microbes. A total of thirty-eight potassium solubilizing microbes were identified and isolated on Aleksandrow Agar media. It was found that thirty-five of them were bacterial isolates and three were fungal isolates. They were further characterized based on morphological and biochemical characteristics. Among them SS 7-6, P-4-1, S-6, SS 5-3, P-1-1, SS 9-2 and SS 7-1 were Gram negative, while SS-13, SS 7-7 and P-21, were Gram positive. The highest solubilization efficiency was observed in case of SS7-6 i.e. 11.50 mm which was followed by SS-13 i.e. 11.30 mm. All isolated KSB were also tested separately for their phosphorous solubilization efficiency. It was observed that the isolates namely SS 5-1, SS 5-2, SS 5-4, SS 7-1, SS7-4, S-6, SS-6, SS 9-1, SS 9-2, SS 9-3, P-1-1, PYS-1, PYS-5B, PYS-5A, P-17, P-21 and three fungal isolates efficiently solubilized phosphorous. Such ‘dual-solubilizers’ can convert fixed potassium and phosphorous source in soil to available form for plants.
