Jorschumb Soybean Test Plot

This plot was located just east of Wheaton on the Norcross tar. There are a couple things to learn from this plot and I'll talk about them after the results. The results are:
Pioneer 90Y41    - 50.7 bu/a
Pioneer P05T24r - 46.2 bu/a
Pioneer 90Y70    - 48.9 bu/a
Pioneer 90M80    - 42.3 bu/a
Pioneer 90Y81     - 47.6 bu/a
Pioneer P10T91r  - 53.2 bu/a
Pioneer 91Y10     - 53.7 bu/a
Pioneer 91Y30     - 49.1 bu/a
AsGrow AG1431 - 44.4 bu/a
Pioneer 91Y41     - 43.6 bu/a
Pioneer P16T04r  - 55.0 bu/a
Pioneer 91Y70     - 43.0 bu/a
Pioneer P19T60r  - 60.6 bu/a

   Colored in blue are the top 4 varieties in the plot. Three of them are brand new and the results are outstanding. The other variety, 91Y10, is also new. What sets the 91Y10 apart however is that it is the only one of the top four not seed-treated. That is a major plus for that variety in this plot.
   Colored in red are 4 varieties that didn't do so well in this plot but all showed signs of a disease called charcoal root rot. I didn't know alot about this disease but luckily our account manager Jim Kokett was observing the plot harvest and he did. Charcoal Rot is showing up quite often this year and is most prevalent in years with a cool wet rainy period early in the growing season, followed by a hot, dry late summer. Sound familiar? The most obvious symptom is leaves hanging on the bean stalks at harvest time. If you take those plants and split them at ground level, you'll find grayish-black spotting in the phloem tissues of the stalk. Varieties will differ on how they handle charcoal rot and the varieties marked in red exhibited reduced yields because of it. If you find that you have a field of beans that exhibited the symptoms of leaves hanging on the stalk as well as less than expected yields, let me know as I'd like to check to see if Charcoal Rot is the problem. Google up Charcoal Rot if you'd like to see what it looks like.
