Hail damage to Soybean: Evaluation and Replant Options (Jul 05, 2017)

Soybean plants with significant amounts of green tissue remaining are likely to survive early-season hail damage, as they can regrow from axillary buds located at the juncture of the stem and leaves. Soybean plants cut below the cotyledons or entirely stripped of leaf tissue will not recover. Similarly, larger plants with a small amount of green leaf material remaining are likely to recover, but expect regrowth to occur slowly.

Soybean can tolerate low plant populations well, with only small reductions in yield potential across wide ranges in stand loss. For instance, populations near 100,000 plants per acre are likely to produce maximum yields, and those around 80,000 will yield about 90% of the maximum.

Replanting should be considered only in fields where the crop is a total loss. Soybeans planted on June 20 are expected to produce around 70 percent of an early planted soybean crop. Replanting during mid-June is likely to produce a yield similar to that in an extremely thin soybean stand; therefore, producers must carefully consider all of the tangential factors: replanting costs, seed availability, weed control, and aesthetics. Seed availability may be the primary determinant for replanting or not.
