MSU Extension Soybeans

The 2022 Michigan Soybean Performance Report is a result of a cooperative effort of the soybean breeding program at Michigan State University, Michigan State University Extension and the Michigan Soybean Committee. This information will help you to make informed critical choices for your 2023 soybean crop. 

This report provides information on the performance of Conventional and Roundup Ready soybean varieties in Michigan in 2022. The presentation of data for the entries tested does not suggest approval or endorsement of varieties by Michigan State University (MSU).

Testing Procedures

Seven locations are reported here. The Central locations for the Conventional and Roundup Ready trials include test sites in Allegan, Ingham, Saginaw, and Sanilac Counties. The Southern locations for the Conventional and Roundup Ready trials include test sites in Hillsdale, Ingham, Lenawee, and St. Joseph (irrigated) Counties. 

Nineteen seed companies entered a total of 160 commercial varieties, not including the experimental MSU lines. The cooperators, planting dates, harvest dates, and other site details for the locations are listed below.

Seed was planted in 6-row plots, 15-inch row spacing at planting rate was 160,000 seeds/acre. Each plot was 17 feet long with a 3 foot alley. Alleys at the Sanilac and Allegan County locations were trimmed to 15 feet long to accommodate for the reel of one of the combines and wider alleys for field days. At each location, varieties were replicated three times in a Randomized Complete Block Design (RCBD). Only the center four rows were harvested. Experimental design, data management, and data analysis were conducted with Genovix, (Agronomix Software, Inc., Winnipeg, Canada).
