Reaction of soybean [Glycine max (L.) Merr.] to seed inoculation with Bradyrhizobium japonicum bacteria

The aim of the study was to assess soybean response to sowing material inoculation with HiStick® Soy preparation, containing Bradyrhizobium japonicum. Based on the obtained results, it was found that the inoculation significantly increased the number and dry weight of nodules on soybean roots compared to control. The bacterial preparation significantly increased the number of pods per plant. As a result, a significant increase in seed yield (0.58 t/ha) was obtained compared to control. HiStick® Soy increased total protein content in seeds. Protein and fat yield was higher after seed inoculation by 318 kg/ha and 101 kg/ha, respectively, compared to control.
