Seed inoculation with Bradyrhizobium japonicum (Kirchner) Jordan is a common production practice for most soybean [Glycine max (L.) Merr.] growers in northwest Minnesota; however, plants seldom are well-nodulated. Our objectives were to (i) identify strains of B. japonicum that enhance nodulation and agronomic performance of Maturity Group 00 soybean cultivars grown on soils having a range of NO3 - -N concentrations; and (ii) asses cultivar-by-strain specificity. Six cultivars and five B. Japonicum strains were evaluated in six field trials during 1988 to 1990. Nonfertilized (1988-1990) and N fertilized (1990), uninoculated controls were included. Soil NO3 - -N concentrations (0-60 cm) at planting ranged from 52 to 175 kg N ha -1. Residual soil NO3 - -N values were low and substantially less than initial values in only three environments. Nonetheless, significant increases in response to inoculation were observed for grain yield, seed weight, and grain N concentration in 17 of 18 comparisons. In 1990 trials, fertilizer N (168 kg ha -1) increased seed weight and grain N concentration significantly more than inoculation. Nodule number (r = -0.89; significant at P = 0.05) and dry weight (r = -0.97; significant at P = 0.01) were inversely correlated with soil NO3 - -N (0-60 cm) at planting. Estimated (difference method) N2 fixation (r = -0.93; significant at P = 0.05) and relative increases in grain yield (r = -0.93; significant st P = 0.05), seed weight (r = -0.97; significant at P = 0.01) and grain N concentration (r MenosSeed inoculation with Bradyrhizobium japonicum (Kirchner) Jordan is a common production practice for most soybean [Glycine max (L.)
