Agricultural soils of Serbia are low in soybean symbiotic bacteria and application of bacteriological preparations has been introduced as a regular cultivation practice when growing soybean. A trial was set up on experimental field of Institute of Field and Vegetable Crops from Novi Sad, Serbia, on chernozem soil using a randomized block design with four replicates. Mineral nitrogen fertilizers were used in rates of 0, 30, 60, and 90 kg/ha in the experiment. Each of the nitrogen treatments had two variations, with and without inoculation. The effects of inoculation and different nitrogen fertilizer rates on yield and yield components were determined based on the pod number, seed number, 1000 seed mass and protein and oil content in seeds. Significantly higher pod number was observed in inoculated plants with the application of 30 kg N/ha. Inoculation with NS-Nitragin increased seed number per plant. In treatment with no mineral nitrogen applied and with application of 30 kg N/ha and 60 kg N/ha, 1000 seed mass was statistically higher in inoculated plants than in uninoculated ones. Inoculation produced statistically signifi cant difference in soybean yield only in the treatment with no mineral nitrogen applied. Inoculation and applied mineral nitrogen rates had no significant effect on protein content in soybean grain.
