Sažetak

In this study the symbiotic interactive effect of different Bradyrhizobium japonicum strains with six soybean cultivars were evaluated under fi eld conditions. The rhizobial strains ASR011, USDA123 and CB1809 respectively showed hostcultivar specifi city with JS335, Lee and Bragg. B. japonicum ASR011 recorded the highest nodulation and nitrogenase activity with all the studied cultivars. Generally, plants inoculated with strain ASR011 produced higher plant dry matter accumulation and seed yield over all other cultivars. On the basis of analysis of correlation coeffi cients, it was
found that plant dry matter accumulation emerged as best criterion for selection of most effective legume-Rhizobium associations for given physical and biological conditions.
