To determine what effect different closing wheel types have on plant emergence and yield. Unfavorable planting conditions were targeted for this study.

It rained two days prior to planting this closing wheel study, which created marginal conditions, but the seed trench was closed in all treatments.

Early in the season, the two Dawn Curvetine™ treatments delivered more uniform plants and overall better looking plant stands. The one Dawn Curvetine and one solid closing wheel resulted in the best yield increase with 2.7 Bu./A., followed by the two Dawn Curvetines with a 2.0 Bu./A. advantage.
