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.

Soybeans

Our soybeans yielded very well this year with a high yield from Kruger® K-393 RR/SCN of 76.3 bu./acre.  The Kruger® K-434 RR/SCN yielded well, but it is really too long a variety for us here in central Illinois with a maturity of 4.3.  Three Stine® varieties came in next with very respectable showings.

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.
