The purpose of this study is to examine how planting depth impacts plant population, emergence and yield.

We observed that the ideal seedbed created last fall with a vertical tillage tool ahead of the planter, coupled with a timely rain immediately following planting, resulted in no visual differences in emergence. Although we experienced a cold winter, we didn’t see any heaving or winter kill in any of the planting depths. Winter heaving may have been more significant had we not had the opportunity to plant early, or if we didn’t have such a warm November and December, which got our root system established prior to dormancy. At harvest, our 1 in. planting depth resulted in the highest yielding entry.
