Swing to sowing canola early

Grain Central, January 19, 2018

SOWING canola early in most southern and eastern Australian cropping regions can increase productivity and profitability by following 10 key tactical guidelines.

The guidelines – relating to location, variety selection, soil moisture management, seed placement and rates, weed, pest and disease management, soil nutrition and croptop/windrow timing – have been established after an extensive three-year investigation as part of a Grains Research and Development Corporation (GRDC) collaborative research investment.

Through the Optimised Canola Profitability project – a collaboration between the GRDC, CSIRO, New South Wales Department of Primary Industries and the South Australian Research and Development Institute (a division of Primary Industries and Regions SA) – 34 field experiments were conducted from 2014 to 2016, looking at the interaction between variety and sowing date.

The experiments were located at 14 sites, from Eyre Peninsula in South Australia and the Wimmera in Victoria through to the central-west slopes of NSW and the Darling Downs in south-eastern Queensland.

One of the project leaders, CSIRO research scientist Dr John Kirkegaard, says the traditional canola sowing window in much of the southern and eastern growing regions has opened in late April, continuing well into late May.

“However, changing rainfall patterns, disciplined summer fallow management and improved no-till seeding systems are enabling growers to capitalise on soil moisture opportunities and reduce production risk by sowing canola earlier in the season,” Dr Kirkegaard said.

“The project was established to quantify potential yield and grain quality benefits from sowing crops in early to mid-April and has focused on tactical agronomic requirements to achieve successful outcomes. We have been looking at varieties that are suitable for earlier sowing and how they should be managed.”

The guidelines for early-sown canola, developed with Rohan Brill (NSW DPI) and Andrew Ware (SARDI), have been published in a new electronic Ten Tips to Early-Sown Canola brochure, available at
