3-Year Data Shows 6.7 Bu/A. Advantage for Dawn Curvetine™ Closing Wheels

Three-year evaluation of the effect different closing wheel types have on plant emergence and yield. Unfavorable planting conditions were targeted for this study.

In this year’s closing wheel study, every closing wheel (when averaged across all pressure settings) outperformed the solid rubber control. We always attempt to plant this plot in less than ideal conditions and this year was certainly no exception. The wet conditions this spring put our closing wheels to the test. As farmers in our marketing area can attest, these conditions reflected the scenario that many of them were confronted with at planting. Overall, the SI Distributing Finger-Till wheels won the plot, with the best bushel per acre gain across all pressure settings. However, various closing wheels performed well at each individual pressure setting, making it hard to pick clear cut winners and losers. We saw our best yield gains across all closing wheel combinations when the pressure setting was on the third notch. This year, wheels that crumbled the seed trench shut from the sides generally outperformed wheels that applied more pressure above the seed. In the wet conditions we were planting into, this action helped decrease compaction above the seedling and allowed for more even and uninterrupted emergence. Wheels that apply more pressure from above would most likely work better in drier conditions, but their pressing action was less desirable in the moist seedbed we worked with this spring. When studying the various charts prepared for this study, please pay special attention to the overall closing wheel summary, the optimum pressure setting for each individual wheel, and the stronger long-term data that we have been building up for the past 2 to 3 years.
