The AgScore project puts different seasonal climate systems under the microscope to better understand which models might offer skilful forecasts up to six months into the future. The project asks ‘How good is the forecast?’ not just in terms of rainfall, but the potential to use the model data to forecast yield and other productivity metrics related to on-farm decision making.

Demonstration sites over two seasons across Western Australia have shown that little consistent evidence that crop varieties respond differently to nutrition strategies. However, results were highly variable and season and location specific highlighting the importance for growers to consider adjusting their fertiliser strategy throughout the year to increase yield or improve grain quality, and ensure inputs are not wasted by the crop.

With herbicide-resistant weeds a continuing challenge, changes in weed spectrums, off-farm grain cleaning is an important tool in the IWM toolkit. This has been demonstrated by increased uptake of off-farm cleaning by Western Australian growers in surveys taken over a seven-year interval.

Corrigin, Western Australia, grower Gavin Hooper is searching for a high-value legume that suits his low-rainfall cropping environment. Hooper and his family have been involved in several GRDC projects and other industry trials aiming to identify pulses adapted for their environment.

A grain protectant, inspired by an insecticidal molecule found in Australian native flora, is soon to become part of the integrated pest management toolbox. Its low toxicity and new mode of action may provide growers with increased flexibility and profitability from being better able to optimise grain sales.
