F.I.R.S.T. CORN PROGRESS REPORT
Iowa East Central, Iowa West Central and Iowa North West
Chris Clark

Chris ClarkThe Sully, IA, field was a third year corn-on-corn location. Despite a highly variable growing season, the plot grew well. An August windstorm caused some root lodging, but the corn was fully harvestable, so the data is reliable. The average yields were 195.9 bu./acre and 192.2 bu./acre for the early and full-season tests, respectively.

Wet soil conditions at planting were a concern at the Liscomb, IA, plot. Plant emergence was a little uneven and stayed that way for the early part of the growing season. Eventually, the plants evened up and produced a good yield. The early season test averaged 199.6 bu./acre. The full-season test had an average yield of 192.6 bu./acre.

Fourteen in. of rain in early May caused severe flooding at the Cavour, SD, location. The rains continued after planting and the early season test was lost. The results of the full-season test were also seriously affected by the excess rain. The average yield was 86.5 bu./acre on the full-season site.
Cavour, SD - Full-Season Test

Soil conditions were good after rains in April and early May at the Beresford, SD, site. Rains continued until June 2, but then ceased completely until Aug. 2. The drought took its toll and at harvest yield range was 0-30 bu./acre. Thus, this location was deemed a crop failure due to the drought, and no results are being reported for 2007.

Wisconsin South and North Central Tri-States
Jason Beyers

Jason Beyers Plants were standing well and stalk quality was good at harvest on Oct. 26 at the Miles, IA, field. Average yield was 197.9 bu./acre on the early season test and 214.4 bu./acre on the full-season test.

North Central State-Line, Iowa South and Wisconsin South
Jason Beyers

Jason Beyers The average yield of 60.4 bu./acre was surprising at the Elkhorn, WI, location given the lack of rainfall in July. August rains were plentiful which helped with pod set. Plant heights were relatively tall, which caused some lodging.
Elkhorn, WI - Soybeans

The Winnebago, IL, field had good rainfall most of the season, which helped produce a respectable average yield of 68.9 bu./acre. Plant heights were all tall, causing some lodging.
Winnebago, IL - Soybeans

Field conditions produced a nice yield of 68 bu./acre at the Farmersburg, IA, field. Soybeans showed no sign of disease, and all varieties were standing well at harvest on Oct. 29.
Farmersburg, IA - Soybeans

The Letts, IA, field had heavy grass pressure for the first four weeks after planting and did not get spray until the middle of June. The average yield of 54.8 bu./acre was better than expected.
Letts, IA - Soybeans

The presence of aphids early in the growing season may have hurt yields slightly at the Warren, IL, field. The average yield was 54.3 bu./acre.
Warren, IL - Soybeans

The Spring Green, WI, location was irrigated, which helped the crop during the hot and dry weather in June and July. Plants were short and had lots of pods/cluster. The average yield was 62 bu./acre.
Spring Green, WI - Soybeans

Good rains in August helped produce nice yields at the Lancaster, WI, field. The average yield was 60.3 bu./acre. Plants were tall and experienced some lodging.
Lancaster, WI - Soybeans

The Watertown, WI, plot had no rain in June and July, but August rains helped save the crop. The average yield was 46.6 bu./acre. There were not many pods/clusters.
Watertown, WI - Soybeans



South Dakota East Central
Mark Querna

Mark QuernaSpring rains provided good moisture at planting at the Trent, SD, plot. Although June and July were dry, light rains in August helped boost yields. However, an early frost on Sept. 14 took some toll on the yield. The site averaged 47.6 bu./acre.
Trent, SD - Soybeans

Early season moisture was good at the Howard, SD, plot. A hard frost mid-September cut the season short, but the soybeans were mostly mature by then. The site's average yield was 52.6 bu./acre.
