Pushing the limits with spring sown winter canola in 2013 locations
Aims

To test the vernalisation theory and answer questions around grazing management.

To test the vernalisation theory and answer questions around grazing management.
 

Key messages
  • Winter habit canola has been successfully sown in spring, grazed over summer and harvested for grain in 2012 and 2013.
  • Establishing canola in spring means larger, more resilient plants in autumn with less impact from slugs and waterlogging.
  • Forage value comparable to commercially available dedicated forage rapes over summer and autumn with added benefit of oil seed production.
  • In 2012, grazing over summer increased grain yield compared with no grazing.  Ungrazed yield was 1.9 t/ ha; grazed was 2.7 t/ha.  Taurus sown at the conventional time (April) yielded 2.3 t/ha.
