WHAT IS THE YIELD GAP?

The gap between Canadian canola yields and Australian canola yields has been widening for the past 10 years and currently stands at around 0.4 tonnes per hectare. This has also reduced the profitability of Canola for some Australian growers. Much of the yield gap is due to the high adoption rate of new technology, including canola hybrids (in Canada approximately 95% adoption). Hybrid adoption in Australia is much lower at around 35% with approximately 40% of the canola area planted to farmer-saved-seed.

At Pioneer, we know our current hybrids have exceptional genetic potential – however, they often fall short of their potential for a variety of reasons. As a result Pioneer has established a number of key areas of focus to Close the Yield Gap over the next 5 years. To find out more about our tactics for Closing The Yield Gap please click here

TRIAL OBJECTIVE:

Our hybrid canola management trial at Cummins on the Eyre Peninsula of SA aims to demonstrate the genetic potential of Pioneer® brand canola hybrids under a best management practice situation. Through demonstration of some key areas including time of sowing, phenology, nitrogen timing and use rates and fungicide applications for disease control, we aim to increase grower knowledge and capabilities in order to achieve the genetic potential of Pioneer® Brand canola hybrids on a commercial scale.

OCTOBER UPDATE

The trial has not been immune to the wild South Australian weather in the past few weeks. The plots have halved in height – like every other hectare of canola on the Eyre Peninsula!

Over 15 agronomists and 50 growers have looked through the trial in September and October. Yield estimates from 22nd September ranged from 3.5T/Ha to 6.3T/Ha. We believe it to be somewhere between 4 and 4.5T/Ha – Still a great crop!

This goes to show that Pioneer hybrids have the genetic potential to achieve higher yields with extra input and a kind season. The trial has also demonstrated the value of early sowing and early timing of Nitrogen application.

Full results will be published post-harvest and will be available from this website. We also have plans underway to repeat the trial in a couple of other areas in South Australia next year. Watch this space!
