| Popis: | Naturalized bradyrhizobia in Argentinian soils originate from introduced inoculants with poor properties. Attempts to improve soybean production by new inoculants usually fail. We wanted to improve inoculation success by a careful selection of competitive inoculants. Initially a field with naturalized bradyrhizobia was used for soybean cultivation using seeds which were inoculated with several inoculant strains, added separately or in mixture in a replicated experiment. Strain E110 was the most competitive strain since it occupied most nodules and resulted in the highest dry matter production. In a second experiment, a soil free of bradyrhizobia was used where a bradyrhizobial strain was introduced to serve as a representative of the naturalized population, and E110 was used as an inoculant. We found that E110 increased plant growth, indicating a potential for use of this strain as an inoculant in soils with less efficient naturalized populations. |
