Brief Project Summary:

With the unpredictable threat of tropical weather and the pressures of harvesting large acreage, the question of whether to use chemical application to hasten maturity often arises in North Carolina soybean production. Several factors need to be considered when considering application of a harvest aid: avoiding grain loss due to shattering or seed quality decline, pre-harvest intervals associated with chemical application, harvestability due to green stem and proper application timing. This research conducted at five locations determines the influence of harvest aid application and harvest timing on soybean yield.

Final Project Results

The use of harvest aid products for desiccation can expedite harvest in a way that allows farmers to achieve optimal yields at adequate moisture, while harvesting their crop substantially earlier. In this study, yields equal to the untreated check were attained while harvesting 14-24 days ahead of a normal harvest time, which could be the difference in avoiding a devastating weather event. Although Gramoxone performed best in this study when applied 7 to 10 days before harvest, the NC Soybean Producers support following the 15-day PHI mandated by the label.

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.
