SARDI's Dr Alan McKay says take-all is the disease likely to catch growers out... Inoculum levels are the highest in more than a decade and growers and advisers managing intensive cereal or cereal/pasture rotations should plan ahead to avoid yield loss later in the season... "If the paddock must be sown to a cereal, then consider barley because any yield losses will be only half that of wheat's potential losses, but inoculum levels will continue to increase."..

With profit margins in the eastern wheatbelt tight, Mr Kirk says even small changes across the production system can have a large impact on profits... "Even a 10 per cent change in running costs, grain yield or secured grain price can impact profits by 50 to 60 per cent," he says... While increasing grain yields in the low-rainfall region is a challenge, Mr Kirk says the better operators have shown it is not impossible: "A 10 per cent increase in yield would require an investment in new technology and practices, but such a move could translate into a $28/ha increase in profits."..

Photo of Cameron Weeks talking to farmers at a field day.. The basic principles of yield forecasting are: understanding stored plant-available water at a given point in time; "likely" rain to come (eg, historical rainfall records and rainfall outlooks); and, "reading" the crop to understand what other factors apart from water may be limiting yield (for example plant density, tillers, weeds, disease, etc)... But for the farmer who wishes to better quantify target yields and look at other factors that may affect crop input decisions, then APSIM (as a subscriber to Yield Prophet) or PYCAL (available from Meredith Fairbanks, mfairbanks@agric.wa.gov.au ) may be of assistance...
