Canola variety by time of sowing in the northern agricultural region locations
  • To see if matching canola variety maturity to sowing time would increase yeilds in the NAR.
  • To compare the response of common RoundupReady (RR) and triazine tolerant (TT) varieties.
Key messages

Early sowing is the key to maximising canola yeild in the Northern Agricultural Region (NAR) All varieties yielded less when sown on April 29 compared to April 14 Yield loss was on average 43kg/ha per day between April 14 and April 29th sowing Using the highest yeilding variety rather than trying to match variety maturity to sowing date was the best option.
