Early canola needs planning

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

That’s according to the Grains Research and Development Corporation, which established the guidelines after an extensive three-year investigation.

Through the Optimised Canola Profitability project, 34 field experiments were conducted from 2014 to 2016, looking at the interaction between variety and sowing date.

The experiments were 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 John Kirkegaard, said the traditional canola sowing window in much of the southern and eastern growing regions 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,’’ he said.
