Title: Effects of co-inoculation with Bacillus cereus UW85 and (Brady)Rhizobia on the nodulation, nitrogen fixation and dry matter accumulation of grain legumes
Authors: Buss, Terry J.
Issue Date: 1-Mar-1998
Abstract: Putative evidence, from both laboratory and field experiments by other researchers, has indicated that Bacillus cereus UW85 can increase soybean (Glycine max L. Merr) growth and yield by promoting nodulation and N$\sb2$ fixation. That work involved only soybeans in situations where indigenous Bradyrhizobium japonicum was often present. The objective of my research was to access the effects of co-inoculation with B. cereus UW85 and (Brady)Rhizobia on the nodulation, N$\sb2$ fixation, and DM accumulation of soybean (Glycine max L. Merr.), field bean (Phaseolus vulgaris L.), field pea (Pisum sativum L.) and lentil (Lens esculenta Moench) both in the growth chamber and in the field. Gnotobiotic growth chamber experiments were conducted. In field experiments, the four legume species were inoculated with a granular formulation of B. cereus UW85. It is suggested that B. cereus UW85 promotes the growth of soybean roots by some unknown mechanism(s). Increases in root nodulation were a consequence of an increase in potential infection sites.
