Other Articles in This Issue: TSM® Research Farm Fertility Trials, 2004 TSM® Micro-Boost Trials, 2004 2005: Time to Look Forward Most every year we put out a corn hybrid and a soybean variety trial.  This year we had 19 different corn hybrids and 10 soybean varieties.  The tables below show how the hybrids and varieties performed. Corn The weather was pretty good for corn this year although we had one problem.  We had high winds in July that knocked some of the corn down.  You will notice that some hybrids did not yield very well because they fell over or were completely cut off about knee high.  However, many hybrids did quite well with the highest yield at 216 bu./acre from Kruger® K-5313 YGCB. We had mostly Kruger® and Stine® in the plot this year with one Mycogen® and one Dekalb® hybrid.  The Dekalb® hybrid had a special seed coat on it although its yield was only average.

The Kruger® K-349 RR did very well because this is a very hearty variety that will do well on poorer soils.  The K-355 RR/SCN variety was the highest yielding soybean variety at the University of Illinois plots in Urbana.
