Abstract: The present research was undertaken in order to study the effect of Acetobacter isolates on performance of sweet corn and response of nitrogen fixing ability of newly collected endophytic bacteria Acetobacter spp. in sweet corn. It comprised of experiments in order to select effective local isolate(s) of Acetobacter in especially for N accumulation, yield and yield attributing characters of sweet corn crop at maturity of crop. The Pot culture experiment was conducted in green house of the Department of Agricultural Microbiology, College of Agriculture, IGKV, Raipur in rabi, 2016-17 with Vertisol (medium fertility status and pH 7.6) by using same sweet corn variety (Sugar-75). Top ten isolates were selected (on the basis of growth performance) from 45 local isolates collected from Raipur and Rajnadgaon districts of Chhattisgarh for future screening study under controlled conditions. The highest green cob yield (28.67g/plant) of sweet corn was obtained from plants raised from seeds inoculated with isolate No.18 which was followed by isolate No.16 (25.35 g/plant). Similarly, highest N uptake was associated with Acetobacter isolate No.18 (329.66 mg/plant) followed by Acetobacter isolate No.16 (301.64 mg N/plant) and minimum was observed in un-inoculated control (139.64 mg/plant).Overall findings of the experiments the performance of Acetobacter isolate No.18 was found superior followed by Acetobacter isolate No.16 with most important BNF parameters related to N and biomass accumulation. Microbial dynamic study also supported that isolate No.18 and 16 were well adapted to the rhizosphere of sweet corn and both the isolates retained their highest cell counts in soil taken from sweet corn rhizosphere during pot experiment. Hence, it was concluded that isolate No18 and 16 were most potent N2 fixing local Acetobacter isolate for sweet corn cultivation in Chhattisgarh.
