An in vitro experiment was carried out at Microbiology Laboratory, Department of soil Science of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Bangladesh to determine the effect of diazotrophic bacteria inoculation on growth and biomass production of sugarcane. Two indigenous diazotrophic bacterial strain isolated from sugarcane rhizosphere i.e. Bacillus cereus (BUSo 13) and Acinetobacter calcoaceticus (BUSo 9) and one reference strain, Azospirillum barsilense (SP 7) collected from ATCC, USA were used to conduct the experiment. Three levels of nitrogen viz., no nitrogen, 50% nitrogen and 100 % nitrogen were provided for the crop. The results of the experiment revealed that diazotrophic bacterial inoculation in sugarcane increased growth parameters and biomass yield significantly over control. The highest leaf greenness (38.67), number of leaves per plant (9.67), plant height (76.00 cm), root length (31.67 cm), dry matter yield (3.17 g), N content in plant (1.52%) and N-uptake (48.12 mg g -1) were obtained in treatment T6 receiving 50% N along with Bacillus cereus (BUSo 13) inoculation.
