Plant density in low rainfall canola locations
Aims

To investigate the plant density response to yield and oil content of TT and RR hybrid canola in comparison with open-pollinated canola.

Key messages
  • Birds preferentially attacked low density treatments and late maturing variety Hyola 450TT.
  • The results from this site should be treated with caution.
