Evaluation of a high‐speed planter in soybean production

Abstract Timely and quality planting of soybean is important to achieve maximum yield potential. Wet spring soil conditions rain frequently shorten the time for farmers plant crops within optimal conditions. New planter technology has been introduced that enables their fields faster more precisely than with traditional planters. Large plot field studies were conducted in Indiana from 2015 2017 evaluate a high‐speed at various speeds multiple seeding rates on soybean. Seedling emergence, distribution, final evaluated. Three [8, 12, 16 kilometers per hour (kph)] two (222,000 321,000 seeds ha −1 ) included all years, an additional speed rate 2016 (20 kph 420,000 , respectively). Overall, did not impact seedling emergence. Uniformity spacing decreased slightly as increased 8 20 2016. Cool wet immediately after likely led inconsistent Final grain was affected by or except when 12 yielded 0.25 Mg higher other speeds. Increasing can be achieved without detrimentally affecting population, spacing,
