    New residue management practice delivers
    Author: Dr Sue Knights, 15 May 2021

    Cropping in the higher rainfall regions of Western Australia brings its challenges in respect to residue management, but the Heggatons near Kojonup are fine-tuning their practice with many benefits including improved water use efficiency.

  • New tool aligns climate models with on-farm decision making
    New tool aligns climate models with on-farm decision making
    Author: Dr Sue Knights, 27 Mar 2021

    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.

  • Long-term no-till trial delivers data legacy
    Long-term no-till trial delivers data legacy
    Author: Dr Sue Knights, 24 Mar 2021

    A long-term trial undertaken by the Western Australian No-Tillage Farmers Association has not only provided significant insights for growers into the principles of conservation agriculture practices, but also added to the international science base and trained future systems-thinking scientists.

  • Oats to be supercharged as GRDC ups the ante
    Oats to be supercharged as GRDC ups the ante
    Author: Dr Sue Knights, 17 Mar 2021

    As Gary Lang’s highest profit earner and with reasonable frost resistance, oats have become a regular part of his cropping rotation at Wickepin in Western Australia. This drives Gary’s keen interest in GRDC’s announcement of a comprehensive boost to oat improvement.

  • Yardstick projects provide feedback on nutrition
    Yardstick projects provide feedback on nutrition
    Author: Dr Sue Knights, 12 Mar 2021

    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.

  • Optimum soil sampling strategies for the west
    Optimum soil sampling strategies for the west
    Author: Dr Sue Knights, 16 Jan 2021

    The highly variable soils in Western Australia can be prone to over or under-fertilising, but a carefully considered sampling strategy can help resolve this.

  • Seed cleaning helps keep the lid on weed banks
    Seed cleaning helps keep the lid on weed banks
    Author: Dr Sue Knights, 18 Dec 2020

    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.

  • Addressing the crop sequence dilemma
    Addressing the crop sequence dilemma
    Author: Dr Sue Knights, 14 Nov 2020

    Growing understanding of biological constraints is driving a rethink on matching crop sequences, that include pulses, to production systems and environments for the medium-rainfall zone of the Western Australia.

  • Sleeves-up search for the elusive pulse option
    Sleeves-up search for the elusive pulse option
    Author: Dr Sue Knights, 02 Nov 2020

    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.

  • Native plants a novel ally
    Native plants a novel ally
    Author: Dr Sue Knights, 19 Oct 2020

    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.
