2023 Abstract - INFLUENCE OF SEED SIZE, SEEDING RATE, AND PLANTING SPEED ON COTTON STAND ESTABLISHMENT: High-speed precision planters are capable of covering more acres per hour than traditional planters and apply variable rates of seed across different management zones. Planting populations can be lowered without yield or maturity penalties if stands are uniform. Recent large-plot studies were established to evaluate the effects of plant populations on 12 cotton cultivars that varied in seed size. The cultivars were planted with prescription rates of approximately 1.0 to 4.5 seeds per row ft at low and high speeds. Reduced accuracy was recorded at the higher planting speed, especially in the high population treatments.
