The objective of the present study was to investigate the comparative roles of nitrogen (50 kg ha-1) and inoculums Bradyrhizobium (1.5 kg ha-1) in improving the yield of two mungbean varieties (BARI mung-5 and BARI mung-6). The experiment was carried out during the period from April 2011 to July 2011 at the Sher-e-Bangla Agricultural University (SAU) Farm, Dhaka. The experiment was laid out in Randomized Complete Block Design (RCBD) with four replications and plot size was 8 m2 with 30 cm line spacing. The Bradyrhizobium strain BARI RVr-403 was used for the experiment. The recommended dose of TSP, MOP and Gypsum were applied in each plot. BARI Mung-6 performed higher stover and seed yield than BARI Mung-5. Bradyrhizobium inoculation significantly increased 1000-seed weight, pods plant-1, seeds pod-1, stover and seed yield. BARI Mung-6 with Bradyrhizobium inoculation recorded the highest seed and stover yield compared to other treatment combinations. Non-inoculated BARI Mung-5 gave the lowest yield.
