To test the best response to narrow vs wide row over high and low rainfall zones of the NAR.
To test the best agronomy for wide rows; hybrid vs open pollinated, seeding rate, fertiliser and fungicide.
Canola grown in wide rows (50-60cm) yielded well enough to consider this row spacing an option. Caomla Plants were able to compensate for being sown in wide rows - biomass similar to narrow rows. We may be able to reduce input costs, sees and fertiliser by refining the production package in wide rows. Wide rows offer benefits of reduced fuel costs at seeding, easy stubble handling and safety of IBS herbicides.
