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 Michigan State University 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

Early season planting time (late April-early May): longer maturity group can improve yield; no benefit from increasing planting population; seed treatment-limited to stand improvement.
Mid season planting time (mid May-early June): limited impact from changing maturity groups; no benefit from increasing planting population (potential for reducing seeding rate); seed treatment-limited to stand improvement.
Late season planting time (mid June-late June): shorter maturity group can avoid poor seed quality; increasing planting population can improve yield; seed treatment-limited to stand improvement.

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.
