Brief Project Summary:
Warm spring temperatures have resulted in soybeans being planted two to six weeks ahead of normal to maximize the length of the growing season, but there is risk of cold precipitation after planting causing chilling injury to seeds. Poor emergence may require producers to re-plant a field, which would negate the yield gains from early planting. This project intends to update recommendations related to early planting and risk of chilling injury after planting to help farmers improve production efficiency. Trials investigate critical durations of cold water exposure during imbibition and seed germination and assess the impact of soil type, planting depth, moisture content at planting and temperature of precipitation on emergence.

Information And Results
Project Summary

Warm spring temperatures have resulted in soybean being planted two to six weeks ahead of normal to maximize the length of the growing season but there is risk of cold precipitation after planting causing chilling injury to seeds. Poor emergence may require producers to re-plant a field, which would negate the yield gains from early planting and result in greater costs. There is an immediate need to update recommendations related to early planting and risk of chilling injury after planting to help farmers improve their production efficiency. Two studies will be conducted to: i) investigate critical durations of cold water exposure during imbibition and seed germination; and ii) assess the impact of soil type, planting depth, moisture content at planting, and temperature of precipitation on emergence. Farmers will be able to use this information to minimize replant waste and capitalize on increased season length benefits from earlier planting.

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.
