Timing of nitrogen in low 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
  • Pioneer 43Y23 (RR) had higher grain yield, oil yield (kg/ha) and gross margins, than Sturt (TT).
  • Grain yield responded to applied nitrogen up to ~ 40 kg N/ha.
  • Both varieties responded similarly to applied nitrogen with no variety x N rate interaction for grain yield. 
  • Oil yield and gross margins did not respond to applied nitrogen.
  • Timing of nitrogen application did not alter the response to nitrogen of both varieties for GY, oil %, oil yield or gross margin.
