District canola variety trial at Witera and time of sowing trials at Minnipa locations

To compare current released varieties at two locations on Eyre Peninsula.

Key messages
  • Early break to the season triggers a very early canola sowing time (22 March) in a time of sowing trial at Minnipa.
  • Disappointing yields and no stand out varieties in time of sowing 1 (TOS1) at Minnipa missing the full potential for early sowing due to shattering and mice damage.
  • Exceptional yields in TOS2 Clearfield trial at Minnipa where Hyola 571 CL, Pioneer 44Y84 CL and Pioneer 43C80 CL all exceeded 2.5 t/ha.
  • ATR Stingray, CB Junee HT and ATR Snapper are the highest yielding TOS2 TT lines at Minnipa.
  • Hybrids Hyola 571 CL, Pioneer 45Y82 CL and Pioneer 44Y84 CL shine in the Clearfield trial at Witera yielding above 2 t/ha.
  • ATR Cobbler, ATR Stingray and Tanami are the best performing TT lines at Witera.
  • Oil content in canola is above 42% across all trials.
