Description

Currently, there is a lot of interest in soybean seed inoculation. Several new products have entered the market and created a renewed interest in seed inoculation even on fields that have a history of soybean production. As a result of this renewed interest and the lack of information from Iowa, a soybean inoculant evaluation trial was initiated this year in Iowa to evaluate these products. Our objective was to determine if we need to adjust our current recommendations when using inoculants. Twelve different inoculants were tested at two locations (Ames and Vincent) in Iowa. Averaged across locations, none of the inoculants resulted in a significant yield increase over the non-inoculated plots. Two of the inoculants (BYEXPS and TagTeam), however, yielded greater that the non-inoculated plots at Ames. Currently, none of the inoculants look to give us a consistently higher yield in the corn-soybean rotation. More data is needed before final conclusions can be drawn.
