Abstract

Current corn development is from just planted to V4 (four-leaf stage) across Iowa. First plantings of corn are reported to have good color and stand, according to Iowa State University Extension field crop specialists on May 21, 2007; although some corn, particularly in the southwest, west, and northwest regions, is exhibiting problematic stands if it was planted between the many rainstorms. In particular, it is corn that was planted under too wet conditions; it would be approximately V2 (two-leaf) or V3 (three-leaf) now. Corn that is placed into a wet seed furrow can have restricted root growth, resulting in "rootless" corn (also referred to as rootless corn syndrome) among other problems that will become apparent as the season unfolds.
