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
  •  In a dry year, there was no economic response to applied N.
