Maximising canola yield by getting establishment right - MACS5 Trial 2 locations
Aims

To evaluate the effect of two triazine tolerant varieties, sown at three different seeding rates and three different depths has on emergence and yield at Minnipa Agricultural Centre and at Piednippie. 

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.

Sow rate or Target density The varieties; ATR Stingray, a small seeded open pollinated variety, (seed size 0.34 gms/100 seeds) and Hyola 559TT, a large seeded hybrid variety, (seed size 0.63 gms/100 seeds) were used in all treatments. The trials were planted at three depths (1 cm,

Harvest date Not specified
Plot size Not specified
Plot replication Not specified
Fertiliser

The Minnipa trial received a total of 65 kg/ha 19:13:0 S9% and 41 kg/ha urea fertiliser, applied at seeding and 50 kg/ha of urea and 120 kg/ha sulphate of ammonia (SOA) broadcast during the season (total of 78 kg/ha nitrogen).
Herbicide

The trials received knockdown herbicide of Sprayseed plus pre-emergent 1.5 L/ha Trifuralin 480 prior to sowing.
Insecticide

Multiple applications of insecticides were applied at both sites throughout the season to control a range of insects.
