Contributor Hart Field Site Group
Trial location(s) Hart, SA
Long term comparison of seeding systems locations
Aims

To compare the performance of three seeding systems and two nitrogen (N) strategies.

Key messages
  • Seeding systems did not affect wheat grain yield, averaging 5.3 t/ha.
  • Good rainfall and cool temperatures during grain fill increased yield potential and the higher N rate resulted in a 1.2 t/ha yield advantage.
  • Available soil N pre-seeding ranged from 80 – 190 kg N/ha with 75 kg N/ha more accumulated under the high N rate.
