Plant growth promoting bacteria are found on the surfaces of roots, and associated with the roots that can promote the growth of the plant both qualitatively and quantitatively. Many bacteria such as Pseudomonas and bacillus were found in the different rhizosphere soil of paddy fields. Pseudomas fluoresecence were isolated in the paddy fields of rhizosphere soil. This isolate were biochemically tested and screened for the growth promoting substances like such as indole acetic acid, hydrogen cyanide and siderophores. This result showed that the organism can produce both the growth promoting and inhibiting substances.

Indole 3 acetic acid, siderophores, Hydrogen cyanide and plant growth promoting substances.
