DIAZOTROPHIC BACTERIA AND FACULTATIVE SYMBIOTROPHIC ASSOCIATIONS IN THE PHYLLOSPHERE OF FOXTAIL MILLET

M. MOHAMMED RAFI AND P.B.B.N. CHARYULU

Abstract

Bacteria were isolated from the phyllosphere of foxtail millet (variety Lepakshi) at 15-day intervals. The bacterial isolates varied in their efficiency to fix nitrogen. Of the 10 selected isolates of bacteria, only 8 isolates were diazotrophs with 5 isolates exhibiting appreciable nitrogen fixation. Further, the isolates obtained from the phyllosphere of 45-day old plants showed maximum nitrogen-fixing efficiency. Most of the axenic bacterial isolates were identified as Beijerinckia indica. Facultative symbiotrophic associations from the phyllosphere also exhibited appreciable nitrogen-fixing activity.
