Selective screening and characterization of plant growth promoting bacteria for growth enhancement of tomato, Lycopersicon esculentum.

ABSTRACT:

Background and objectives

Plant Growth-promoting Bacteria (PGPB) can replace the dangerous chemical fertilizers and pesticides. The aim of this study was to isolate the PGPBs for Lycopersicon esculentum plant and to determine the appropriate volume for inoculation.

Materials and methods

Plants samples were collected from tomato fields. Nitrogen fixing-PGPBs were isolated from rhizoplane and rhizosphere. Five isolates were screened based on their growth abilities and examined for PGPB traits including phosphate solubilization, and IAA, ammonia and HCN production. After high cell density cultivation, the cells were separated by centrifugation and freeze dried after resuspension in cryoprotectant. The powders were inoculated into sterile soil with a dose of 10⁶
