The influence of seed inoculation with a bio-preparation of nodule bacteria Rhizobium leguminosarum, fertilization of 0, 40, 80, 120 kg N/ha and molybdenum topdressing on the yield of green mass, dry matter, seed, average number of pods per plant, average number of seeds per pod, average nodule number per plant, nodule dry weight as well as plant and seed protein concentrations were studied during two years of investigations on two soils - Mollic Gleysols and Eutric Cambisols. The highest values of all investigated parameters were obtained in the inoculated seed variants with Mo application, except the average nodule number per plant where the highest values were achieved in variants without No. The effect of N fertilization depended on the soil type, i.e. its chemical properties. The largest number of the investigated parameters obtained the highest values as a result of fertilization with 40 kg N/ha on Mollic Gleysols. Thus, seed yield was 4.02 t/ha, nodule dry matter 0.482 g per plant, whereas seed protein concentration was 26.91 %. On Eutric Cambisols, the highest values for most of the studied parameters were obtained with 80 kg N/ha as the seed yield amounted to 3.65 t/ha, nodule dry matter was 0.456 g per plant and seed protein concentration 26.48 %.
