Maximising canola yield by getting establishment right - upper EP experience in 2013 locations
Aims

To maximise canola productivity through creating soil specific management strategies that improve canola yields, profitability and establishment in field trials on lower and upper Eyre Peninsula.

 

Key messages
  • Early sowing had the largest positive impact on canola yield when comparing a range of treatments trialled in 2013. Good seeding depth and the correct seed rate were also important in maximising canola yields, but not to the same extent as time of sowing.

Sow rate or Target density 40 plants/m2 and 60 plants/m2
Sow date 23 April 2013 4 x dates 2013:TOS1: 23 April TOS2: 7 MayTOS3: 17 MayTOS4: 27 May
Harvest date Not specified
Plot size 1.5m x 10m
Plot replication 4
Fertiliser

The trial received a total of 63 kg/ha 19:13:0 S9% + 64 kg/ha urea fertiliser, applied at seeding and 100 kg/ha sulphate of ammonia (SOA) broadcast during the season.

Herbicide

500 ml/ha Intervix, 300 ml/ha Select, 100 ml/ha Lontrel and 0.5% Supercharge was applied to control weeds

Insecticide

Multiple products were used during the season to control insects, but there was still some damage from Diamond back moth and aphids in all trials discussed in this article.

Other trial notes

Not all trial results are presented for this trial. Time of sowing had a large impact on yield, where the earliest sowing time produced the highest yield with each subsequent time of sowing producing significantly lower yields. The time of sowing did have an effect on establishment, but this did not correlate to the differences in yield achieved. Other treatments such as sowing depth and seeding rate (results not shown), while significantly affecting establishment did not significantly affect grain yield within the same time of sowing (i.e. all treatments sown on the same day, regardless of sowing rate and sowing depth did not yield significantly different to each other.) A similar trial was established in the high rainfall zone of lower Eyre Peninsula, near Wanilla, and similar results were achieved.
