Isolation, screening, and molecular characterization of plant growth promoting rhizobacteria isolates of Azotobacter and Trichoderma and their beneficial activities.

Objectives: The present study was conducted for isolation, screening, and identification of Azotobacter and Trichoderma from different soil samples.

Methods: A total of 10 isolates of Azotobacter and Trichoderma were isolated from rhizospheric soils. The test isolates were biochemically characterized and screened in in-vitro conditions for their plant growth promoting properties.
