Deep ripping results over several sites and seasons are not always clear locations
Aims

To investigate deep ripping over several sites and seasons .

Key messages
  • The deep ripping site at Kojaneerup showed no consistent canola yield response in 2017
  • Two consecutive frosts and extreme rainfall in late September reduced yield potential.
  • Small differences in yield were not consistent within yield zones nor replicates.
