Abstract
A corn emergence demonstration was established at the University of Missouri Graves Chapple Extension and Education Center. The objective was to show how emergence if delayed decreased corn yield. Corn emergence was marked using different color stakes and then individual corn plants were followed through the growing season. Plants were evaluated for stunting, lodging, death, barren stalks and individual ears kernel weights measured. Corn plants started emergence 10 days after planting. More than 70% of the corn plants emerged the first day and anther 25% emerged the second day. The last plants emerged 12 days later. Stunted plants occurred throughout the emergence dates, not just the late emergers. Kernel ear weight was measured for each of the emergence dates and emergence dates with lodged plants caused by a straight wind. Lodged plants had reduced kernel ear weight compared to standing plants within emergence dates.
