A field experiment was conducted at department of agricultural microbiology at UAS Dharwad to test the two potassium solubilizing bacteria and one phosphorus solubilizing bacteria on growth and yield maize in comparison with the 75 per cent and 100 per cent fertilizer level as absolute control. The maize seeds were treated with KSB 11, KSB 27 and PSB 98 (2). From this research results showed that there were increased in plant height, leaf area, and increased yield as compare to control among all the treatments dual inoculation of KSB and PSB with 75 per cent N and P was recorded maximum growth and yield parameters of maize crop. This result concluded that dual inoculation of KSB and PSB have more effective as compare to individual application to the Maize.
