Closing Wheel Study - Why The Dawn Curvetine Won This Year.

To determine what effects different closing wheel combinations have on plant emergence and yield. In this study, ten closing wheel combinations were tested on four different pressure settings. The control in this study was the solid rubber closing wheels. Unfavorable planting conditions were targeted for this study, While wheel pressure settings were maintained at optimum pressure for performance and field conditions.   

Summary:   
In this year’s study we found that at the Kentucky PFR location, the Dawn Curvetine performed the best over the control (2 rubber closing wheels). The Dawn Curvetine also gave us our best emerged stands. The combination of a Yetter Spike and rubber closing wheel came in second with a yield of 194.7 Bu./A. When we look at the 2 year average at the Kentucky PFR site shown in Figure 1, the Yetter Spike Wheel with one rubber wheel has performed the best at 5.1 Bu./A. above the control. This is the first year that we looked at the Dawn Guagetine and Curvetine combination. In this year’s study, it was one of only three that gave a positive response.

Beck's Hybrids PFR program conducts more than 75 different studies across multiple locations (500+ acres) to learn how different management practices and new technologies perform in field environments. Simply put, it is research focused with the farmer in mind. To see the entire study, please download the PFR Book and see page 115.
