Plant Growth Promoting Rhizobacteria (PGPR) is a community of bacteria located in the
rhizosphere of plant which are can suppress directly or indirectly plant diseases caused by
different plant pathogens and also promote plant growth. Twenty three rhizospheric soil
samples of chilli plants from Southern Plateau and Hills region agro-climatic zones of
Karnataka and Andhra Pradesh states of India were collected and isolated on four
different types of media viz. TSA (Tryptone soya agar), NA (Nutrient Agar), CPG
(Casamino peptone glucose) and Kings’ B media in the present study. A total of thirty one
bacterial isolates were isolated and screened their antagonistic against Ralastonia
solanacearum UTT- 25 and plant growth promoting activities in vitro condition. Out of 31
isolates of rhizobacteria, 35.4 % rhizobacteria showed antagonistic ability to inhibit
growth of R. solanacearum. In vitro screening of PGP activities rhizobacteria showed
phosphate solubilization (64.2%), production of IAA (78.5%), production of ammonia
(78.5%), production of HCN (35.7%), and siderophore production (50%). The
rhizobacterial isolates showing plant growth promoting activities along with having
biocontrol potentials were characterized using morphological, biochemical and
physiological. These rhizobacteria are good potential to use as biopesticide and
biofertilizers for improving crop health and growth.
