Iowa West Central and Iowa East Central
Chris Clark

Chris ClarkThe Central City, IA, field had a rough growing season. The location had a wetter-than-normal spring, followed by wet and windy conditions during spraying season which delayed herbicide application. An August windstorm also caused some root lodging and down corn. The stress caused below-average yields of 173.7 bu./acre and 172.1 bu./acre for the early and full-season tests, respectively.

Illinois North
Jason Beyers

Jason BeyersThe Grand Ridge, IL, field was planted May 8 and harvested Oct. 6. The average yield was 68.7 bu./acre, which was about 10 bu. above last year's yield at this location. Ample rainfall throughout the summer helped produce this excellent crop.
Grand Ridge, IL – Soybeans

The Malta, IL, field had a below-average yield due to lack of rainfall at the right time. Average yield was 43.3 bu./acre, and many plants only had 1-2 pods/cluster.
Malta, IL – Soybeans

The Walnut, IL, field had an average yield of 66 bu./acre, thanks to good rainfall. Tall soybeans caused some lodging, and white mold also affected some varieties.
Walnut, IL – Soybeans

Excess rain after planting hurt the germination at the Milledgeville, IL, field. The entire plot was lodged and matted at harvest. Average yield was 57.2 bu./acre.
Milledgeville, IL – Soybeans

Minnesota South Central and Minnesota Central
Rick Querna

Rick Querna The Nicollet, MN, field had adequate rains early during the growing season, then experienced a dry spell from June through the first part of August. A 5-in. rain in mid-August helped boost the average yield to 64.2 bu./acre.
Nicollet, MN – Soybeans

The Glencoe, MN, field had excellent growing conditions in May and early June. August also offered ideal weather with nice rains. Average yield was 54 bu./acre.
Glencoe, MN – Soybeans

At Litchfield, MN, good early season growth along with rain in late August helped save yields. Average yield was 55.9 bu./acre. The field was sprayed for aphids.
Litchfield, MN – Soybeans

The Clinton, MN, field had good growing conditions following planting, but dry and hot temperatures were experienced in July. Moderate rain in August and good subsoil moisture helped the crop produce a 54.4-bu./acre yield.
Clinton, MN – Soybeans

Pest pressure throughout the growing season at the Cottonwood, MN, field stunted the growth and yield of this test. Because the effects were not uniformly distributed across the field, none of the hybrids performed consistently and the data was rejected for this year’s report. This site will not be included in the calculation of regional average yields.
Cottonwood, MN – Soybeans

South Dakota East Central, South Dakota Northeast and South Dakota Southeast
Mark Querna

Mark QuernaThe Humboldt, SD, plot was planted May 14. Planting conditions were favorable, but rainfall was scarce during June and July. In August, enough rain fell to help the soybeans fill pods. The site averaged 47.4 bu./acre.
Humboldt, SD – Soybeans

Soil moisture was plentiful at the Parker, SD, plot at planting on May 15. Conditions were favorable most of the growing season, and August rains helped fill out the soybean pods. The site averaged 62.5 bu./acre. This was an above-average year at this location. Average yield at this site was 53.1 bu./acre in 2006 and 56.5 bu./acre in 2005.
Parker, SD – Soybeans

Heavy rain in May and June caused flooding at the Cavour, SD, plot. The field showed uneven emergence and poor stands due to this excess moisture. However, yields were considered good despite the weather. The site averaged 53.5 bu./acre.
Cavour, SD - Soybeans

Planting conditions were wet in May at the Webster, SD, plot. In June and July conditions were drier and higher levels of aphids were noted. The site averaged 47.7 bu./acre.
Webster, SD - Soybeans

Bath, SD, had excess rain prior to planting, followed by a dry summer. The field averaged 41.7 bu./acre. This was below the expected average annual yield of 45 bu./acre.
