Cereal growers in western Australia have, traditionally, burned cereal stubbles. Burning stubble residues reduces weed seed populations and fungal pathogens, but its main purpose has been to eliminate straw which might cause blockages od seeding machinery and por see-bed preparation in the time critical seeding operation.
In 982, the Department of Agriculture began a project to determine whether wider spaced rows also depressed cereal yields in Western Australia. This article summarises some of the important results from that work.
