Occurrence Of Nitrogen Fixing Bacteria In Turmeric Rhizosphere
ABSTRACT
The soil sample used in this study was collected from the
rhizosphere of turmeric plant dated National Root Crop Research Institute
analysis. Nitrogen-fixing microorganisms were iSOlr onas by spread-plate
technique on the solid medium. The study revealed the presence of
NitrOSOrn;ieCted europea and Azotobacter species. The total Hetertrophic
bacterial load of soil samples coPe total from rhizosphere of turmeric plant
showed range from 1.08 x 108 to 7.8 x 10 whi1 isolates nitrifying bacteria
count ranged from 1.9 x iO4to 4.8 x iO4. Shows the distribution Of obacter from
soil samples. Nitrosomonas europea had the frequency of 2 (33.3%) while
AZObj1jty to species had 4 (66.7). Nitrogen fixing rhizobia have been reported
to vary in their, symbiont compete, infect and fix nitrogen in their hosts due
various factors such as host, extremes, compatibility, soil salinity; soil pH,
mineral and heavy metal toxicity, temperature inadequate or extreme soil
moisture and nutrient deficit.
