Abstract
Bacteria that colonise plant roots and promote plant growth are referred to as Plant Growth- Promoting Rhizobacteria (PGPR). Rhizobium bacterial isolated from soil samples (PEC 1 and PEC 2) collected from prathyusa college garden soil. The emergence of seedlings, from the seed at a height of 2 mm was treated as germination. PEC1 and PEC2 inoculated seed germination, coefficient and vigor index value remarkably changed compared to control groups. PEC2 showed better responses compared to PEC 1 and control groups.
Keywords: Plant Growth-Promoting Rhizobacteria (PGPR), germination, bhendi and vigor index
