A seed tube for an agricultural planter having a rearwardly curving forward wall, a rearwardly curving rearward wall and opposing sidewalls defining a seed passageway which curves rearwardly from an upper ingress end toward a lower egress end. Wear resistant material is disposed proximate the egress end which provides a point of first contact with the opener disks thereby preventing appreciable wear of the egress end of the seed tube.
