Rains, Hail, Wind: Déjà vu All Over Again?

requent and heavy rainfall in recent days has caused flooding of rivers, creeks, and streams throughout parts of Indiana. Large ponded areas exist in fields distant from floodwaters.  Storms in recent weeks have also included damaging winds and hail that caused additional damage to a number of cornfields.

The consequences to grain yield and quality from the damage caused by the flooding/ponding and wind are difficult to pinpoint with much accuracy because little research exists that addresses these chance-occurring yield-limiting factors.  Risks and expectations, however, can be outlined.

Author’s Note: This article is 99% identical to one I first published in July of 2003 following near record rainfall events that caused massive flooding of rivers/creeks as well as extensive ponding in low lying areas of fields. As Yogi Berra once was quoted, "This is like déjà vu all over again."
