This report provides information on the performance of Conventional and Roundup Ready soybean varieties in Michigan in 2024.*
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 150 commercial varieties, not including the 48 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, 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
The 2024 growing season in Michigan was marked by some variable weather conditions across the state for soybean farmers. Early spring saw mild temperatures and some rainfall, allowing for timely planting despite occasional wetness in the soil.
Summer temperatures were warm, with ample rainfall in June, promoting good growth, though heat stress and dry conditions in late July and early August reduced yields in some areas. Despite rain during flowering time and good canopy growth, white mold was not a problem in most areas.
Limited moisture during October created dry harvest conditions for most of the state. Overall, the season featured variable conditions, with farmers in more balanced weather zones seeing better results, while those facing heavy rains and heat stress saw reduced yields.
Soybean performance trial harvest ran from October 6 through November 12. Consistent rain throughout the early part of the season led to overall high yields in the MSU trials and grower fields. More rain in the later part of August would have contributed to even higher soybean yields for the state.There was a variable soil spot in the Central RR Late trial in Allegan, resulting in variable data, which is not published in this report.
