Aims

To demonstrate the relative performances of the three canola options available to Western Australian growers

Key messages
  • Intermittent prevailing dry conditions experienced through the growing season probably impacted negatively on the residual activity of Atradex WG and Intervix in the TT and CL canola systems respectively, while resistance to Group A and Group B Herbicides would also have been a contributing factor.
    • Final weed control ratings (out of 10):
    • Roundup Ready canola system – 9.9
    • Triazine Tolerant canola system – 7
    • Clearfield canola system – 7.5
  • The trial was harvested 5th November (168 days after sowing). Yield data are shown below. The high yields and oil content probably reflect timely rain rather than a particularly good season. There is some discrepancy between the yields of the trial and the paddock average harvested by Andrew. The harvest contractor is confident that the figures reflect the true yield for the site and suggest that this area of the paddock was possibly a high yielding area compared to other areas of the paddock, or that the impact of small plot water harvesting may have played a role. The trial is more about relative performance than actual performance: on average the RR system yielded 38 percent higher than the TT system and 15 percent higher than the CL system.
  • System specific input costs used in calculations in the table above provide a ball park summary of specific costs associated with each system. They are not hard and fast figures, to be disputed. It is appreciated that each and every item is subject to negotiation with suppliers so readers are encouraged to re-work the figures to suit their experience and anticipated costs for 2011.
  • The trial demonstrates that in this instance growers would have on average an additional $500 per hectare to meet other costs when growing RR canola over TT canola (purchased seed) or an additional $465 per hectare over TT canola (using farmer saved seed – assuming that the same yields are obtained for these TT crops).
  • Again in this instance growers would have on average an additional $225 per hectare to meet other costs when growing RR canola over CL canola (purchasing all seed) or an additional $190 per hectare over CL canola (using farmer saved seed).
  • These additional earnings per hectare are even more attractive when one considers the fact that the level of weed control achieved by the RR system was significantly better than that achieved by the other two systems.
