To determine the response to increased crop nutrition and to determine yield potential of leading commercial spring canola varieties.
• Yield potential in this trial was limited by a hailstorm on 12 December.
• High input management (including high rates of mineral fertiliser plus 5 t/ha pig manure) increased grain yield by 0.29 t/ha compared with low input (modest rates of mineral fertiliser only).
• The Clearfield varieties 45Y93 CL and 45Y95 CL had the highest yield at approximately 3.8 t/ha. The glyphosate and triazine tolerant varieties all yielded less than 3 t/ha.
• The high input management strategy had a small negative effect on grain value, dropping oil concentration by 0.8%. There were larger oil concentration differences between varieties ranging from 42.9% for 45Y95 CL to 45.9% for 45Y28 RR.
• Assuming a grain price of $700/tonne, gross income of 45Y95 CL was $2674 and the gross income of 45Y28 RR was $2015, highlighting the importance of yield over oil for income.

Hail Hail damaged the trial site in the early hours of Monday 12 December, leading to considerable pod damage and seed loss in the ripe spring types. Winter types still had green pods and were not affected. |
