The two-year results showed no yield advantage for the application of foliar fertilizers, foliar fungicides or between RR® and LL® soybeans. This lack of any yield advantage for the foliar applied treatments is probably a result of good soil fertility and no diseases being present as was the case for most of NW Missouri.. In poorer soils or under the right environmental conditions these practices could be a benefit. However if the issue is not preset, there does not appear to be a benefit to the application of these products.
The row spacing trial showed an increase in yield for the 15-inch rows over the conventional 30-inch rows during the second year of the trial and no statistical differences the first year. We hypothesize the differences in the weather patterns between the two years accounts for the differences.
The yields for the six different planting populations followed a curve with the yield flattening out between 120,000 and 140,000 planting population and decreasing above that level. An increase in seed costs for the higher populations did not translate into higher crop yields thus reducing overall profitability.
