While most of the corn in the Southeast is a lot farther along than the Indiana corn in this Indiana Prairie Farmer story, I think corn farmers here will also be interested. The story discusses some research done on the impacts of row spacing, convention versus no-till, and cool weather conditions. It showed that cool weather definitely slowed the emergence of the plants, but that they still emerged earlier than expected. It also showed that conventional tillage corn plants emerged about a day earlier than the no-till planting. There was also more variability from row to row than expected.
