Canola trials: Nitrogen Efficiency Trial – Nitrogen Timing Trial (Finley) locations
Aims

To assess whether the optimum timing for applied N interacts with N rate

Key messages

• Different N timing strategies had no significant effect on yield irrespective of N rate applied (80, 160, 240 kg N/ha)
• Applied N fertiliser (based on urea 46% N) significantly increased yield over the unfertilised crop up to the highest rate of 240 kg N/ha.
• Dry matter production at 80% flowering significantly increased over the unfertilised crop when N fertiliser was applied at the early timing (Post sow pre-emergence (PSPE)/6 leaf).
• Nitrogen removal at 80% flowering was significantly increased compared to the unfertilised crop when N fertiliser was applied at the early timings (PSPE/6leaf), however N removal at the later timing (green bud/yellow bud) was only increased at the highest rate of N fertiliser (240 Kg N/ha).
• Oilseed test weight was significantly higher when Nitrogen application was delayed until 6 leaf/green bud (62.8 kg/hl) or green bud/yellow bud (63.0 kg/hl) compared to PSPE/6 leaf application (62.2 kg/hl)
• Grain oil content decreased as N application and yield increased.
