Abstract
The main objective of this study was to evaluate the influence of soybean inoculation with different Bradyrhizobium japonicum strains and the application of Bioalgeen-S90, as a growth regulator, on photosynthetic pigment content and soybean yield. Regarding the main objective, both greenhouse experiment and field trials were conducted. The positive effect of interaction between Bioalgeen-S90 and seed inoculation with B. japonicum strain D344 on photosynthetic pigment content was determined in greenhouse experiment. The results from field trials showed a significant influence of Bioalgeen-S90 on chlorophyll b and a+b content and soybean yield. Regardless of the B. japonicum strain used, inoculation had a significantly positive effect on chlorophyll a, b and a+b content. Compared to the non-inoculated control variants, inoculation with both B. japonicum strains, showed the statistically significant effect on soybean yield. The simultaneous application of Bioalgeen-S90 and B. japonicum strains caused the highest yield increase.
