Maximising canola yield by getting establishment right - MACS5 Trial 1 locations

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

In 2015, seven separate trials were conducted as part of this project at Minnipa Agriculture Centre and Piednippie on upper Eyre Peninsula. Three trials will be reported in this article. Further trials were conducted on lower Eyre Peninsula and will be reported in the LEADA results booklet.

Key messages
  • Early sowing (22 April) had the largest positive impact on canola yield when comparing a range of treatments trialled in 2015, similar to results observed in 2013 and 2014. Sowing on 22 April improved yields up to 12%, depending on variety, compared to 29 April sowing date.
  • Different management practices are needed to establish canola on different soil types under marginal moisture conditions. On a loamy soil at Minnipa deeper sowing (to 4 cm) produced the highest yields, whereas shallower sowing (1 cm) produced the highest yields at Piednippie, particularly with the smaller seeded variety Stingray.
  • Trials at Piednippie in 2015 showed that yields up to 0.8 t/ha are achievable in a below average rainfall season, provided the crop is established early and achieves around 50 plants/m2 in open-pollinated varieties.
  • Results from similar trials in 2013, 2014 and 2015 have all shown that the highest yielding canola has consistently come from plots with plant establishments of over 50 plants/m2 for open pollinated varieties and 40 plants/m2 for hybrid varieties.

The trial received a total of 69 kg/ha 19:13:0 S9% + 57 kg/ha urea fertiliser, applied at seeding and a further 50 kg/ha of urea and 52 kg/ha sulphate of ammonia broadcast during the season (total of 72 kg/ha of nitrogen).


800 ml/ha Atrazine (500g/l a.i), 90 ml/ha Verdict and 1.0% Kwicken was applied to control weeds.


Multiple products were used during the season to control insects.
