The purpose of this study is to evaluate how planting depth impacts plant population, emergence and yield and how these factors are further impacted by planting date.

4-YEAR MULTI-LOCATION PLANTING DEPTH YIELD AVERAGE

To maximize yield potential, it’s critical to take the time to ensure your planter is set correctly to achieve proper planting depth for variable field conditions. Ensuring proper seeding depth is one of the easiest things we can do to set ourselves up for a successful growing season. As in previous years, our 2 in. planting depth was the optimal depth for maximizing yield across all of our testing sites in 2018. Although soil temperatures may be slightly cooler at deeper depths, the 2 in. seeding depth does ensure a more stable and consistent environment for moisture imbibition and seedling germination. This helps us maintain uniform emergence across the field and properly placed root systems for the duration of the growing season. An adequate root system is critical to aid the plant in moisture and nutrient uptake, especially during periods of dry weather.
