The state experienced a hard freeze Oct. 10 and 11, ending a growing season that had been slowed by rain and, in some areas snow. Despite the overall cool growing season – highlighted by a warm period in early September – the USDA October yield estimate of 186 bushels per acre in Iowa is the highest on record. As often happens with high grain yields, quality issues are surfacing. This article summarizes current field conditions, looks at test weight, weight shrink, and corn storability; two other articles in this series discuss field molds and storage management.
