Please click download above for the complete report.
This report provides information on the performance of Conventional and Roundup Ready soybean varieties in Michigan in 2025.*
Soybean trials are reported for Central and South zones of Michigan. 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 151 commercial varieties, not including the 48 experimental MSU lines. The cooperators, planting dates, harvest dates, and other site details for the locations are listed in the full report.
Seed was planted in 6-row plots, 20 feet long with 15-inch row spacing, at a depth of 1.5-inches. The planting rate was 160,000 seeds/acre. At each location, varieties were replicated three times in a Randomized Complete Block Design (RCBD). All locations were planted to 17 feet with 3-foot alleys. Alleys in Allegan County were trimmed to 5 feet wide, other alleys were not trimmed. Only the center four rows were harvested. Experimental design, data management, and data analysis were conducted with Genovix (Agronomix Software, Inc., Winnipeg, Canada).
Growing Conditions.
A review of Michigan's 2025 growing season shows that a dry spring with moderate weather provided for some early planting and overall normal planting conditions. The planting season for the MSU soybean research plots ran from May 15th to June 2nd.
Soybeans experienced favorable mid-season moisture from July rains. However, August-September drought conditions hit most of Michigan, especially from the Saginaw Bay to Grand Rapids area. This stressed late pods and, in some cases, affected bean size. Due to dry conditions at the Hillsdale location, slight field variations affected yield and caused high coefficient of variation, so yield data is not included in this report.
Overall weather patterns provided warm temperatures in September and through most of October. Most soybeans were dry and ready to harvest slightly earlier than normal. Soybean performance trial harvest ran from October 6 through October 27. The Lenawee location ended with very high yields.
