Biotic nitrogen fi is a phenomenon mainly depended on mutualistic interrelation between host plant and root nodule bacteria. This interrelation affects photosynthesis and productivity of biological N-fixation and requires studies of biological particularities of grown legume cultivars and effectiveness of Bradyrhizobium strains used for seed inoculation. A field experiment was conducted on the territory of Nesvizhskaya Crop Testing Station (Minsk region, Republic of Belarus). Based on chlorophyll and nitrogen content in soybean leaves, number of nodules on roots of cultivars grown, and on quantity of nitrogen accumulated in plants, four soybean cultivars were assessed. The cultivar Pripyat (control) has poorly responded on inoculation, whereas cultivars Slavyankа an Sobrini responded well by increase of chlorophyll and nitrogen content in leaves and by larger number of root nodules. As a result, they produced unusually high seed yields. Therefore, these soybean cultivars may be recommended for wide use in regions of Belarus.
