description A flat seed disk is provided with a series of circumferentially arranged se ed retaining protrusions providing seed retention at locations offset axially from the remainder of the disk. The offset allows the seed to fall in the correct location of the seed tube to reduce unwanted seed bounce and provide better seed delivery to the ground and better seed spacing as compared to flat disks without the offset. In one embodiment, the protrusions have seed retaining faces opening generally in t he direction of disk rotation. In other embodiments, the faces are angled away from the direction of rotation to reduce interference between released seed and adjacent protrusions, and trailing radial ledges can be provided to enhance seed retention.
