Abstract

Broadcast and drill seeding of Brassica napus L. were compared at four seeding rates. Drill-seeded material yielded more than broadcast-seeded material, particularly at the low seeding rates. Broadcast-seeded plants had more branches and pods than drill-seeded plants. Seeding method did not affect number of seeds per pod or 1,000-seed weight.
