Improving the early management of dry sown cereal crops locations
Aims

Research trials were established in 2019 to assess the impact of management on seed germination and establishment on three different soil types in field trials and pot experiments; a red loam [Minnipa Agricultural Centre (MAC)] and two grey calcareous soils (Cungena and Streaky Bay) for:

  • Impact of fertiliser type (P and N) and fertiliser placement,
  • Impact of practices, herbicides and seed dressings.

This article reports on field trials undertaken in 2019 at three sites.

Key messages
  • At Streaky Bay and Cungena in 2019, establishment was similar with dry sowing or sowing at the break, and at Minnipa establishment was better with dry sowing.
  • There was a yield penalty if no fertiliser had been applied at Minnipa.
  • Dry sowing increased grain yield at Minnipa by 0.2 t/ha compared to waiting for the break in the season.
  • Dry sowing at Streaky Bay and Cungena reduced grain yield, by 0.7 and 0.3 t/ha respectively, compared to waiting for the break and sowing into a moist soil bed.
  • All three sites showed a decrease in early dry matter with dry sowing.
  • The herbicides and fungicides evaluated in the trial did not impact on plant establishment when dry sowing.
