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
  • RR hybrid canola maximised gross margins
  • OP TT variety Sturt produced similar gross margins to the hybrid TT variety Hyola 450 TT
  • Gross margins were optimised at:

             ~ 50 plants/m² for Sturt TT.

                5 to 25 plants/m² for Hyola 450TT.

              ~ 13 plants/m² for Pioneer 43Y23 RR.
