Abstract: Experiment was conducted to study the effect of Bradyrhizobium inoculation at different nitrogen levels viz. 0, 20, 40, 60 and 80 kg N ha-1 on Binamoog-2. Bradyrhizobium inoculation increased dry matter production, nodulation, pod production, seed yield, harvest index and benefit cost ratio. Nitrogen negatively affected on nodulation and harvest index. Increase of nitrogen fertilizer increased seed yield up to 40 kg N ha-1 and straw yield up to 60 kg N ha-1. Highest seed yield (1607 kg ha-1) and benefit cost ratio (2.35) obtained when 40 kg N ha-1 was applied with Bradyrhizobium inoculation.
