What Is "Rouging Corn" in Iowa?

Definition

Rouging corn (sometimes spelled "roguing") is the practice of removing husks from ears while still on the stalk to expose kernels to sun and wind.

Purpose

• Accelerates field drying.
• Promotes even moisture reduction.
• Reduces mold and mycotoxin risk.
• Improves test weight and storability.

Methods

• Hand-rouging (labor-intensive, small fields).
• Mechanical corn pickers with husking beds (commercial scale).

Common in Iowa's humid harvest seasons when natural dry-down is slow.
