Research probes profitability of canola systems.. Caption: CSIRO-led research under the GRDC project 'Achieving stable and high canola yield across the rainfall zones of WA' is continuing in 2015... "In most areas of the WA grainbelt, the question for growers becomes - do I use hybrids simply as a weed control tool due to their greater vigour, even if they're not necessarily making me more money in the short-term," he said...

WA guidelines sought for hybrid canola.. DAFWA senior research officer Mark Seymour says overseas research shows hybrid canola, which is a first cross produced from two parents, has the advantage of early vigour, weed competition, nitrogen efficiency and yields. ".. Farmers are discouraged from retaining hybrid canola seed due to genetic variation in subsequent generations, and retaining seed is not permitted by seed companies for RR varieties," he says...

Growers who burn their windrows and have auto-steer should move their windrows by about one metre each year to avoid costly losses of nutrients from their paddocks, according to new research... Mr Newman said the preliminary study by DAFWA investigating the cost of nutrient removal from harvest weed seed management systems was conducted as part of GRDC supported integrated weed management (IWM) research in the northern grainbelt... Mr Newman said the conservative value of nutrients (potassium and nitrogen only) burnt in wheat windrows if an auto-steer harvester followed the same path each year was $42.75 per hectare, and $13.15/ha if the harvester moved across by one metre annually...
