Iowa State University (ISU) recently completed a five-year study of high-speed planter equipment in corn and soybeans. The study utilized a 12-row planter equipped with the Precision Planting SpeedTube high speed planter system and a 24-row planter equipped with the John Deere ExactEmerge high speed planter system (Figure 1). Both planters utilized individual row hydraulic downforce and were tested using a side-by-side strip trial experimental design. Each planter was used on approximately 400 acres per year. Additionally, a third planter with a standard drop tube seed delivery system was included in select fields for seed spacing comparisons.
