Abstract:

Interaction between soil microbes and minerals play a major role in environmental cycling processes, which leads to the mobilization of nutrients from soil components into available forms for biological uptake which enhances crop growth and yield. In the present study four (4) potassium solubilizing bacteria (KSB), eight (8) zinc solubilizing bacteria (ZnSB) and two (2) zinc solubilizing fungi (ZnSF) isolated from Rice, Maize, Cotton and Sorghum rhizosphere soil collected from Student and College farm Rajendranagar PJTSAU Hyderabad. The isolated KSB isolates screened for solubilization of insoluble potassium source (potassium alumino silicate) and zinc oxide (ZnO). The solubilization zone for potassium is ranged from 160 mm to 85 mm. The isolate KSB-2 showed maximum solubilization zone of 160 mm. The solubilization efficiency (%) ranges from 212.50 to 150 % which was maximum for KSB-3 (212.50 %). The solubilization zone is ranged from 16 mm to 6 mm for zinc oxide (ZnO). The isolate ZnSB-3 showed maximum solubilization zone of 16 mm. The solubilization efficiency (%) ranges from 333.33 to 150 % which is maximum for ZnSB-1 (333.33 %). The isolate ZnSF-1 showed maximum solubilization zone of 85 mm followed by ZnSF-2 with 34 mm for ZnO. The solubilization zone is ranged from 6 mm to 25 mm for ZnP. The isolate ZnSB-8 showed maximum solubilization zone of 25 mm for zinc phosphate. The solubilization efficiency (%) ranges from 157.14 to 500 % which was maximum for ZnSB–8 (500.0 %) and least for ZnSB- 6 (157.14 %).
