Splitting of nitrogen in medium-high rainfall canola locations
Aims

To investigate the response to changing the nitrogen rate and changing the time of application.  Canola yield and oil will be measured and RR hybrids will be compared with open-pollinated TT types (OP TT).

Key messages
  • Hyola 404RR outperformed ATR Stingray.
  • Canola yield responded positively to applied N.
  • Oil decreased as N rate increased.
  • N had no effect on gross margins.
  • Timing of nitrogen had no consistent effect on grain yield, oil or gross margins.
