The interrelationship between the altered rhizosphere microflora and rhizobia in the rhizospheres of green gram, black gram ahd sunnhemp following foliar spray with gibberellic acid (50 and 100 ppm). 2,4-dichlorophenoxy acetic acid (5 and 10 ppm) and indole acetic acid (250 and 500 ppm) was assessed. A positive correlation existed between the bacterial and rhizobial populations in the rhizophere of the three plant species. However, no such correlation was apparent between fungal and Rhizobium population in black gram while a positive relationship in green gram and a negative correlation in sunnhemp was evident. The interaction between actinomycetes and rhizobia revealed a positive influence in green gram and black gram while such a relationship did not exist in sunnhemp.
