Evaluation of nodulation and yield of soybean crops due to the application of different formulations inoculants. The application of different formulations of Bradyrhizobium japonicum inoculants on nodulation and yield of soybean in the center of the province of Santa Fe was evaluated. The treatments were: uninoculated, inoculated with B. japonicum, with B. japonicum more Nod factors and with B. japonicum more bacterial protectors. Nodulation patterns corresponded to a soil with good supply naturalized rhizobia population. The number of nodules showed satisfactory nodulation of the plants, although the weight values of the nodules were low. Treatment inoculated Nod factors presented favorable effect on root development. The yield was higher in inoculated treatments, showing increases between 3.5% and 10.8% compared to the control. Soybean plants inoculated with B. japonicum more Nod factors showed the highest yields
