Abstract

In the present study, the maximum rhizobacterial population was observed in Nutrient Agar (NA) (average; Cfu=135×106) followed by King’s-B (average; Cfu=57×106), Soil extract agar (SEA) (average; Cfu=11×106), and Trypticase soy agar (TSA) (average; Cfu=9×106). Screening of arsenic tolerant rhizobacterial isolate revealed that about 1% of the bacterial isolate was from Nutrient Agar and King’s-B survived at 20ppb arsenic concentration, while 0.8% and 0.7% survived from TSA and SEA media respectively. 50ppb arsenic tolerant rhizobacteria were screened for plant growthpromoting activity such as IAA, Phosphate solubilization, Siderophore production, ACC deaminase activity. Maximum IAA activity was observed in rhizobacterial isolates, isolated from all different media. P- solubilizer, Siderophore producer, ACC deaminase, proline, and TSS activities were observed in the isolates of NA media followed by King’s-B media. 50ppb tolerate best suitable PGP traits producing isolates were inoculated to observe carrot plant growth in the pot experiment, Interesting and significant (p<0.05) result were observed in King’s-B media producer isolates; (Pseudomonas) induces
plant length, chlorophyll-a and chlorophyll-b content of the plant after 60 days followed by 30 days.
