Among a total of 18 cultivable rhizobacteria isolated from Curcuma longa grown tropical region of Tamil Nadu, India. Two isolates were evaluated screened for different PGP traits. Based on the above studied parameters, rhizobacterial isolates AUPF25 and AUBM29 were selected for investigation and identified as Pseudomonas fluorescens and Bacillus megaterium by 16S r RNA gene sequencing. The ability of this isolates to assess the impact of bioinoculants application on turmeric (Curcuma Longa L.) plant productivity under pot culture conditions. Understanding the growth performances of turmeric plants inoculated with bacterial biofertilizers under pot culture conditions is a key to improve crop production further in field (15-20%). Turmeric plants with 5 different combinations of bacterial bioinoculants in the liquid formulation were applied as single and dual combinations. The experimental plants were maintained based on complete randomized block design (CRBD). Both biotic and a biotic factors that influence the plant growth including soil nutrient status, plant hypotrophy, phyotochemical composition, bacterial population density were taken into consideration and those were analyzed. Among the bioinoculants combinations applied worked out better than the single and chemical inoculation. The treatment such as T4 concluded as best combinations of bioinoculants and those were also found as compatible.
