Effects Of The March 17, 2026 Freeze On Soybean Plants And Their Recovery

The initial planting for a soybean date of planting by population trial at the Dean Lee Research and Extension Center occurred on March 3, 2026. On March 17, 2026, a freeze event resulted in damage to the unifoliate leaves and apical meristem (the primary growing point) of the main stem.
