WARREN, Ill. — Jung 7V635 was the best in the field of 54 varieties in a full-season hybrid corn test plot farmed by the Harbach Partnership in Jo Daviess County, Ill.

The Jung hybrid yielded 229.7 bushels per acre, with an estimated gross income of $1,558.30 per acre. The second-highest yielder was Channel 209-85VT3P, which produced $221.40 bushels per acre, with an income of $1,504.

Third-place Croplan variety 6125VT3 yielded 218.7 bushels per acre, with a gross income of $1,480.40.

This test and an early-season test on the partnership’s property was conducted by Farmer’s Independent Research of Seed Technologies (F.I.R.S.T.).

The top-yielding Jung variety was grown on moderately well-drained Osco/Musatune silt loam, which was conventionally-tilled in the fall with no irrigation. Pest management included the use of Force, Lumax and Stratego.

Corn preceded the 2011 crop, which was planted May 9 at a rate of 35,100 seeds per acre. A stand of 33,200 plants per acre was harvested on Oct. 15. F.I.R.S.T. Site Manager Jason Beyers said the test produced excellent corn, despite the extreme conditions this plot encountered.

“High winds with the July 11 storm caused most hybrids to have some degree of root lodging. Plant health on most hybrids was still good at the time of harvest. Others showed signs of Anthracnose, but very little of other diseases,” Beyers said.

In the early-season test, FS Seeds FS56TV4 was the top yielder, with 229.4 bushels per acre and a gross income of $1,317.20. Although Cornelius C447VT3 provided the second-highest yield at 226.9 bushels per acre, it provided a bit more income, at $1,319.20.

Number three on the list was Kruger K4-9205, at 222.5 bushels per acre, translating to $1,295.60.
