Effect of sowing date and applied phosphorus on canola grain yield locations
Aims

To test the hypothesis that less fertiliser P is required to acheive maximum grain yield if a mid-maturing variety (Hyola 559TT) is sown earlier than the traditional date of 25 April.

Key messages
  • There was no significant interaction between sowing time and phosphorus (P) in response in 2014 and 2015.
  • Both sites and years responded positively to P fertiliser with 10kg P/ha achieving a relative yield of 88% and 97% in 2014 and 2015 respectively.
  • Further research is required to determine if winter canola requires less applied P than slow spring phenology types (due to teh longer vegetative phase to accumulate biomass by flowering.
