- Fifteen bacterial isolates were tested for their plant growth promoting and deleterious effects towards maize at both the Hinds and Curtiss Research farms of Iowa State University. Isolate effects on maize plant speed of emergence, height and silking were detectable at the Curtiss farın, but were generally lacking at the Hinds farm. Past cropping history of the soils may be an important factor in the successful elucidation of plant growth promoting rhizobacteria and deleterious rhizobacteria. Keywords : Rhizosphere bacteria; bacterial isolates, maize
