seeds/A = target stand ÷ (germination × survival)
seeds/ft = seeds/A × row width (ft) ÷ 43,560
units = seeds/A × acres ÷ seeds per unit

Many university trials find final stands of roughly 100,000–120,000 plants/A are enough for top yield in good conditions; aim higher for late planting, poor seedbeds, narrow-row disadvantages or IDC-prone ground, and lower where white mold is a concern. Read the seeding-rate guide →
