Thus, this research aimed to select the appropriate PGPR strains
that perform higher plant growth promotion than those of
commercial strains (Azotobacter sp. and Azospirillum sp.) when
forage corn (Z. mays L.) cv. Suwan 5 was used as a crop representative.
In addition, the effects of selected inoculant strains on
microbial community structure in the rhizosphere of forage corn
were also investigated.
