Ready in time for the 2013 harvest, it is an initiative of the Grains Research and Development Corporation (GRDC) Albany port zone Regional Cropping Solutions Network (RCSN) and was produced by the Department of Agriculture and Food (DAFWA) with support from the Australian Herbicide Resistance Initiative and growers... Project leader Alex Douglas, of DAFWA, said excellent HWSC studies had previously been conducted in WA's northern and central grainbelt but less had been known about effective methods used by growers in southern areas, where seasonal conditions are unique... "HWSC provides growers with the opportunity to more effectively manage weed populations and allows them to move away from the almost complete reliance on herbicides for weed control," she said...

To help address the knowledge gap Grain Orana Alliance (GOA) chief executive officer Maurie Street recently conducted a trial on his property in Central West New South Wales to examine the effects of windrow burning... Mr Street says growers need to look further than chemical solutions to manage herbicide-resistant weeds in no-till systems... "I have concerns about herbicide resistance and felt that we needed to try something different that wasn't just another herbicide," Mr Street says...

Canola is often windrowed to ensure all pods are mature at harvest... In summary, windrowing too early can result in lower yields and oil contents and too late will lead to shattering losses... Canola is sold into a deregulated domestic market and the responsibility of finding an acceptable price and arranging a buyer rests with the grower...

" Nutrient removal - the hidden cost of chaff windrow burning Peter Newman, Department of Agriculture and Food, Geraldton carts and KEYMESSAGES The value of nutrients removed in a chaff cart when harvesting wheat in 2011 was $13/ha compared to $43/ha for windrow burning... The analysis suggests that lupin residue contains higher levels of potassium than cereal or canola; this is from a small number of samples only... The cost of a unit of potassium was estimated at the time of writing and will vary considerably...

EARLY PLANNING KEY TO DIRECT HEADING Many grain growers fear that direct heading canola is risky and that high shattering losses are inevitable... Yield losses due to shattering while direct heading are likely to be lower than yield losses associated with windrowing a crop too early, such as a week or more before 40 to 60 per cent of seeds on the main stem have changed colour... Direct heading is not suited to paddocks with significant variations in soil type and/or topography - factors that affect plant-available water and plant maturity...

direct heading allows for maximum yields if canola is harvested on time and the header is set-up correctly to avoid shattering... yield losses due to shattering while direct heading are likely to be lower than yield losses associated with windrowing a crop too early, such as a week or more before 40 to 60 per cent of seeds on the main stem have changed colour...
