Uniform Stand and Narrow Rows are Needed for Higher Double-crop Soybean Yield

Double-crop soybean producers do not always realize a yield benefit when they convert from a 15-inch planter to a 7.5-inch grain drill. Poor seed singulation with drills was suspected to limit narrow-row yield response. Experiments were conducted to determine if a precision drill with 7.5-inch row spacing and accurate soybean seed singulation would improve stand uniformity and/or increase yield over a standard grain drill with poor seed singulation or a vacuum-meter planter with 15-inch row spacing and accurate soybean seed singulation.
