THE INOCULATION OF SOYBEAN SEEDS WITH NITROGEN - FIXING BACTERIA IS OF GREAT IMPORTANCE FOR THE CULTIVATION OF THIS SPECIES, AVOIDING THE NEED FOR NITROGEN FERTILIZATION. THE OBJECTIVE OF THIS STUDY WAS TO EVALUATE THE INFLUENCE OF DIFFERENT RATES OF BRADYRHIZOBIUM JAPONICUM INOCULUM ON THE PHYSIOLOGICAL QUALITY OF SOYBEAN SEEDS. THE EXPERIMENT WAS DEVELOPED AT THE SEED TECHNOLOGY LABORATORY AT THE STATE UNIVERSITY OF MINAS GERAIS. SEEDS OF THE NIDERA NS 7300 IPRO VARIETY AND THE GRAP NOD INOCULUM WERE USED. THE EXPERIMENTAL DESIGN WAS COMPLETELY RANDOMIZED (DIC), WITH FIVE TREATMENTS AND FOUR REPLICATIONS. THE ANALYZED VARIABLES WERE: PERCENTAGE OF GERMINATION, SHOOT LENGTH, ROOT LENGTH AND SEEDLING WEIGHT. THE DATA WERE SUBMITTED TO ANALYSIS OF VARIANCE BY THE F TEST AND THE MEANS COMPARED BY THE TUKEY TEST (P�‰¤0.05). THE DIFFERENT DOSES OF THE INOCULANT BASED ON BRADYRHIZOBIUM JAPONICUM DID NOT PRESENT SIGNIFICANT DIFFERENCES BETWEEN THEM FOR THE ANALYZED VARIABLES.
