ABSTRACT

Sixteen soil isolates/mutants of Azotobacter chroococcum which were phytohormone producers and non producers were tested for their comparative performance on wheat crop under pot house conditions. A. chroococcum strains producing all the three phytohormones (indole acetic acid, gibberellin, kinetin) performed better with respect to all the growth parameters over the strains producing any two phytohormones or only one. The phytohormone non producer strain (Mala 11) performed poorly with respect to all the growth parameters. Exogenous application of pure phytohormones also improved the plant growth.
