Abstract:

An attempt was made to isolate, screen, and evaluate the different Plant Growth Promoting Rhizomicrobial consortia on growth parameters of sweet corn (Zea mays convar. saccharata var. rugosa). In the course of the study, as many as five Acetobacter, four phosphate solubilizing bacteria and four potassium solubilizing bacterial isolates were isolated from the rhizosphere soils of Malnad regions. Further all the isolates were screened under in vitro condition. Out of five Acetobacter isolates, Aceto-5 fixed a maximum of 4.8mg of nitrogen/g of carbon source. Hence Aceto-5 was selected for further studies. Similarly, Out of four PSB isolates the maximum inorganic phosphorus was released by PSB-3, hence it was selected and with reference to potassium solubilization, the KSB 3 was efficient. Hence all the efficient isolates viz., Aceto-5, PSB-3 and KSB-3 were selected. Further the effective native Plant Growth Promoting Rhizomicrobial consortia carrier based formulations was developed and evaluated on growth parameters of sweet corn. With respect to germination percentage, number of leaves, chlorophyll content and plant height, the triple inoculation treatment resulted better than other treatment imposed indicating the combined inoculation of PGPR is having an impact on sweet corn. Finally, the treatment where Acetobacter-5, phosphate solubilizing bacteria-3 and potassium solubilizing bacteria-3showed maximum accumulation of NPK content in leaves after 90 days and the same treatment also showed increased residual nitrogen, phosphorus and potassium level in the soil.
