Abstract
Dry bean seed at ambient and elevated moisture levels was passed through four different commercial air-seeders prior to sowing with standard small plot equipment. Seed damage, plant stand and yield for each treatment were compared to a control treatment. Significant changes in plant stand, yield and in percent visual seed damage were attributable to cultivar, seed moisture and seed distribution system interactions. Passing dry bean seed through air-seeding systems with impact distributors caused a significant increase in seed damage and a significant reduction in both plant stand and yield. Raising initial seed moisture content to 16-18 % reduced the damage caused by air-seeders with impact distributors.
