Trial location(s) Buntine, WA
Canola density response in low rainfall environments – East Buntine locations
Aims

To compare the plant density response of yield and oil content between hybrid and open-pollinated (OP) canola in Triazine tolerant (TT) and Roundup Ready (RR) herbicide tolerance groups.

Key messages
  • In a low yielding season canola yield reached a plateau at between 20 and 40 plants/m².
  • Hybrid canola reached a plateau at lower density than open-pollinated canola.
  • Canola yield held up at high density well, even though plants became severely stressed in early winter and early spring.
  • Hybrid canola had a significant yield advantage over open-pollinated (OP) canola in a below average season.
