Disc seeding and time of sowing locations

To compare the performance of disc and knife-point seeding at two different sowing times (early and late)

Key messages
  • Time of sowing is more important than seeding system.
  • Depth control on disc seeding systems can affect crop establishment.
  • In this trial the knife-point press wheel seeding system out yielded the single disc seeding system.
