Potassium is a vital component of plant nutrition package limiting crop yield and quality that performs a multitude of important biological functions to maintain plant growth. The isolation of potassium solubility bacteria (PSB) were carried out using soil sample of Vicina faba plant rhizospore samples. The bacterial isolates were selected exhibiting highest potassium solubilization and characterization on the basis of colony morphology and biochemical characters. The screening of PSB on the basis of growth diameters and zone formation, were measured. Among the six PSB, the PSB6 was maximum activity as well as zone formation than followed by other strains. The plant hormones are a group of naturally occurring, organic substance which influencing the physiological processes. PSB1 to PSB6 strain has maximum potential for production of plant growth hormone such as Indole acetic acid and Gibberellic acid was determined. The Indole acetic acid synthesized from PSB1 bacterial strains which stimulatory primary in leaf primordial and young leaves and in developing seeds. It was 102.5, 98.9, 72.7, 33.4, 121.2, 176.4 and 179.4µg/ml with PSB1, PSB2, PSB3, PSB4, PSB5 and PSB6 strains reported respectively. Whereas Gibberlic acid was 108, 78, 89, 56, 121 and 159µg/ml with PSB1, PSB2, PSB3, PSB4, PSB5 and PSB6 bacteria were estimated respectively. The sideroplores are molecular receptor that binds and transports iron content. It was 1.6, 3.9, 8.9, 1.4, 0.8 and 0.4µg/ml and the potassium solubilizing strain of PSB1, PSB2, PSB3, PSB4, PSB5 and PSB6 performed respectively. Among the all the strains, PSB3 was excellent production of iron binding activity when compared with other strains whereas hydrogen cyanide (HCN) is a electroplating, chemical synthesis and production of synthetic fibers between potassium and PSB1, PSB2, PSB3 and PSB4 was tested and performed the structural functioning when compared with other strains of rhizobium bacteria.
