Harvest results favorable It's been a bumper crop in many harvest locations. In the reports below, the managers of F.I.R.S.T. (Farmer's Independent Research of Seed Technologies) provide a weekly snapshot of how corn and soybeans are yielding. These managers conduct on-farm research trials from farms just like yours. Take a look at their area's summaries and then click on the reports in blue to see exact harvest information from on-farm tests.

Hot and dry weather early in the growing season at the Roanoke, IN, location set the corn crop back. Good rain in late June and July turned things around some. Average yields were 174.1 bu./acre on the early season test and 178.7 bu./acre on the full-season test.

Extremely dry conditions plagued the Reading, MI, plot. Rain in August brought the plants back to life, but did not boost the final yield much. Average yield was 110.3 bu./acre on this all-season test.
Reading, MI - All-Season Test
At the Riga, MI, plot, dry conditions reduced the yield potential. Plant health at harvest was good despite the dry year. The average yield was 150.6 bu./acre for the all-season test.
Riga, MI - All-Season Test
Dry growing conditions and insufficient nitrogen fertilization resulted in an average yield of only 78.8 bu./acre for the all-season test at Marshall, MI.

The Mason, MI, plot had delayed emergence, which caused later pollination. But, this allowed plants to take advantage of the August rains and produced a respectable average yield of 146.6 bu./acre for the all-season test.

The Fayette, OH, plot produced a good yield for the growing conditions it experienced. There was poor emergence due to crusting after planting. A June rain helped the plot get going. The average yield was 154.4 bu./acre for the all-season test.
Fayette, OH - All-Season Test
Dry conditions after planting resulted in short plant heights at the Dunkirk and Leipsic, OH, plots. This allowed late-season grass to emerge and rob both locations of their full potential. The average yield was 127.6 bu./acre for the all-season test at Dunkirk and 138.6 bu./acre for the all-season test at the Leipsic location.

The Celina, Bowling Green and Caledonia, OH, locations all had dry conditions early in the growing season. Then, timely rains helped produce good yields. The Celina plot had an average yield of 196 bu./acre for the all-season test. The Bowling Green field averaged 171.4 bu./acre for its all-season test, and the Caledonia location had an average yield of 219.8 bu./acre on the all-season test.

Wet soil conditions at planting were a concern at the LeHigh, IA, plot. The location experienced weather extremes all growing season, but managed to tolerate the conditions and turn out a nice yield. The early season test averaged 190.6 bu./acre. The full-season test had an average yield of 195.4 bu./acre.

Weather was a factor affecting yields at the Keystone, IA, field. The plot emerged well and grew fine until a dry spell from June 20 through late July hampered growth. A mid-August windstorm also caused a fair amount of stalk lodging and stalk breakage. Average yields were 159.6 bu./acre and 160.6 bu./acre for the early and full-season tests, respectively.

At the Nicollet, MN, plot, growing conditions were good until the weather turned dry in early June. Minimal rain fell until a 5-in. soaker occurred in mid-August. Average yield was 198.4 bu./acre and 203 bu./acre on the early season and full-season tests, respectively.

The Lake Crystal, MN, location had optimum spring weather and moisture. Drier conditions prevailed from early June through early August. Then, welcome rains were received from mid-August through harvest. Average yield was 149.9 bu./acre on the early season test and 165.1 bu./acre on the full-season test.

The Lancaster, WI, plot struggled early on due to wet soils. Germination was spotty, and yield levels were considerably lower than field averages in the area. At harvest a large amount of stalk rot was noted. Average yield was 162.5 bu./acre on the early season test and 164.2 bu./acre on the full-season test.

Wet conditions most of the growing season hampered the corn at the Elkhorn, WI, field. Additionally, a flush of grass growth late in the season pulled corn yields down. Average yield was 143.7 bu./acre on the early season test and 145.3 bu./acre on the full-season test.

Prolonged dry and hot conditions stressed the corn at the Arlington, WI, location. In August, 15 in. of rain fell, but the high winds and wet conditions caused some root lodging. Several hybrids also had a number of dropped ears. Average yield was 162.8 bu./acre on the early season test and 162.1 bu./acre on the full-season test.

Planted May 15, the Macomb, IL, plot had an average yield of 48.6 bu./acre. Some varieties experienced plant lodging, which made it necessary to slow down the combine and lower the reel at harvest. Seed quality produced varying sizes from medium to large.

The Tremont, IL, plot had robust plant growth and yields. Plant lodging was noted in some varieties at harvest. Average yield was 59.3 bu./acre.

August heat coupled with minimal rainfall caused lower yields at the Virden, IL, site. The site also had high SCN egg counts in 2006, which may have contributed to the reduced yield. Average yield was 43.1 bu./acre.
Virden, IL - Soybeans
The Clayton, IL, site produced a disappointing average yield of 33.7 bu./acre. Lack of rain late in the season and hot days in August were to blame for the reduced yield.
