Studies on the inoculation effect of PGPR on the enhancement of growth and yield parameters in rainfed groundnut (Arachis hypogaea L.)

Author(s): S Dinakar
Abstract: The application effect of different formulations of Bradyrhizobium and Paenibacillus cells, viz., single strain inoculation, co-inoculation and co-aggregates application together with 75% recommended N and P level on the enhancement of growth and yield parameters of rainfed groundnut was studied under in-vitro conditions. It was observed that the application of each formulation of Bradyrhizobium and Paenibacillus cells augmented the growth and yield parameters of rainfed groundnut to a higher level when compared to uninoculated control. However, the application of Bradyrhizobium and Paenibacillus cells, as, natural co-aggregates, exhibited the highest performance followed by co-inoculation and single strain inoculation of PGPR cells. It was concluded the application of PGPR cells viz., Bradyrhizobium and Paenibacillus as Interbacterial co-aggregates, together with 75% recommended N and P level augmented the growth and yield parameters of rainfed groundnut to the highest level when compared to control (100% recommended N and P level without bio inoculation) and thus a saving of 25% recommended N and P level is possible due to co-aggregates formulation of PGPR cells.
