Abstract
Current demand for soybean grain [ Glycine max (L.) Merrill] may lead to a conversion of pasture and Conservation Reserve Program fields into soybean or corn ( Zea mays L.) production. Our objective was to determine the effect of soybean seed inoculation with Bradyrhizobium spp. and fertilizer N application rate on soybean productivity planted 1 and 2 yr after conversion to row crop production. Soybean followed the pasture the first year and followed an intervening corn crop the second year. Treatments consisted of a factorial arrangement of seed inoculation and fertilizer N rate. Application of rhizobia inoculum significantly increased soybean grain yield by an average of 130 kg ha −1 Plant dry matter (DM), N concentration, N accumulation, and grain N were also increased with soybean seed inoculation; however, seed quality was not affected. Fertilizer N application increased plant DM but did not increase grain yield, with or without inoculation. Furthermore, N fertilizer did not increase plant N or improve seed quality. Results from this study indicate that growers should inoculate soybean seed when planted after long‐term grass pasture. Application of N fertilizer is not suggested even if no rhizobia seed inoculation is used because fertilizer N did not improve grain yield.
