The objective of this paper was to use nitrogen fixation parameters to determine the optimum amounts of mineral nitrogen needed when growing soybean using inoculation with the biofertilizer NS-Nitragin. The soybean cultivar Balkan and four rates of nitrogen fertilizer (0, 30, 60, and 90 kg N/ha) were used in the experiment. Just before sowing, the seed was inoculated with the soybean biofertilizer NS-Nitragin. Inoculation had a positive effect on nodule number (205% increase), weight (59% increase), and nitrogen content (60% increase). Inoculation accompanied by a nitrogen rate of 30 kg/ha produced the best nodulation and the largest weight and highest nitrogen content of nodules.
