Brief Project Summary:

Earlier planting in soybean in combination with genetic improvement has provided a synergistic increase in on-farm soybean yields in the Midwestern U.S. In addition, recent changes in weather patterns (e.g. early onset of spring) might allow for an earlier planting in northern states like Michigan, as well as cause delay in planting (e.g. wet spring). However, limited research has been conducted on management strategies to maximize yield as well as profitability in soybean planted at various times during the growing season. Selection of maturity group, seeding rate, and application of seed treatment are some of the management strategies that could vary based on planting time and help improve...

Information And Results
Project Deliverables

Information generated from this research will be used to develop and demonstrate recommendations for optimizing management strategies for soybean planted early vs late in the growing season in Michigan. Results will be disseminated to growers and stakeholders in Michigan through extension presentations at regional and county level winter extension meetings and summer field tours. Newsletter articles and factsheets generated from research findings will be posted on the MSU Extension News Field Crop Production webpage and email newsletter (http://msue.anr.msu.edu/topic/info/field_crops). Research findings will also be presented at the annual meeting of the American Society of Agronomy. A final report will be provided to MSPC at the completion of this research.

Final Project Results

Optimum planting date is important for higher soybean yield, quality and profit.
Selection of longer maturity group for early planted soybean.
Seeding rate is low as 90,000 seeds/acre had no significant effect on net return.
Response to higher seeding rate under late planting conditions.
Benefits from seed treatment were limited to stand improvements.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
