Key Messages
- Hybrid canola (43Y92 (cl)) consistently produced 20-30% more grain yield than open pollinated (ATR Stingray) canola across key Mallee soil types at Karoonda in 2018.
- Given the decile 1 season, yields were substantial and ranged from 0.35-1.16 t/ha with yields of more than 0.9 t/ha achieved on all soil types.
- Hybrid canola appeared to have a lower fertiliser N requirement as it produced significantly more grain than open pollinated canola at each level of N input.
