Purdue Soybean Performance Program
Suggestions for using these results to select top-performing varieties
The results provide producers with an independent and objective evaluation of the performance of soybeans sold in Indiana .
- Use multi-year data in tables 1-9 (3yr averages) and tables 1A-9A (2yr averages).
- Use multi-location average data (tables 1B-9B). Consider single location results with extreme caution.
- Evaluate consistency of performance of the varieties you are interested in over years, across locations in other zones.
A. Look for varieties that are consistently in the top group (those with an asterisk).
B. Beware of varieties that have up and down performance. - Look at several other reliable, unbiased trial results focusing on consistency.
- Test varieties on your farm. Try to get experimental numbers and put them in your test for two years.
Remember you are taking a tremendous gamble if you make variety selection decisions based on one year yield comparisons in only one or two local test plots .
