Investing in RD&E to create enduring profitability for Australian grain growers

    Optimising Cereal Grain Yield

    Optimising Cereal Grain Yield

    Between 2017 and 2019 strategically placed wheat trials, located as far north as Central Queensland down to the Riverina region of NSW delivered data that will provide grain growers with regional information about variety adaption and recommended sowing times.

    The project is part of a bilateral agreement under the grains agronomy and pathology partnership between GRDC and NSW DPI, who brought Queensland’s Department of Agriculture and Fisheries onboard to work on the project.

    Tactical Nitrogen Agronomy

    Tactical Nitrogen Agronomy

    New research into Nitrogen applications as part of the Tactical Wheat Agronomy for the West project could challenge the way the industry thinks about what determines the timing of N applications.

    The research project, a WA Department of Primary Industries and Regional Development and GRDC investment, involved trials across Western Australia’s wheatbelt and revealed a key influencer of wheat yield, quality and protein level, is environment.

    Rhizoctonia in 2020

    Rhizoctonia in 2020

    Rhizoctonia is a fungal disease that’s causing some concern to growers in the Southern and Western regions.

    On this podcast we speak to SARDI scientists Alan McKay and Blake Gontar about some of the management options available to growers and, in particular, how they can lessen the presence of the disease in the soil moving in to 2021.

    Inter-row cropping under the microscope in the Southern Region (Part 2)

    Inter-row cropping under the microscope in the Southern Region (Part 2)

    A GRDC investment could see growers in the southern region growing crops like wheat and canola and even peas in the same paddock at the same time.

    Inter-row cropping is not new, but scientifically evaluating it on a broadacre scale is new. On Part 1 we heard Agriculture Victoria crop scientist, Garry O’Leary explain the aims of the multi-site trials.

    On Part 2, senior research agronomist, Penny Rifkin takes us into the paddock at Hamilton in Victoria to explain some of the challenges and opportunities that are already revealing themselves.

    Inter-row cropping under the microscope in the Southern Region (Part 1)

    Inter-row cropping under the microscope in the Southern Region (Part 1)

    It’s radical. It certainly looks different. But the potential benefits could be enormous. It’s called intercropping – growing two or more crops in the same paddock at the same time.

    In Part 1 of this two part mini-series, we hear about the sheer scale of trials underway across Victoria and what is hoped to be achieved.

    Agriculture Victoria crop scientist, Garry O’Leary dreams of a future that might be, but with a big dose of realism tossed into the mix.

    Yield losses from red leather leaf in oats

    Yield losses from red leather leaf in oats

    Yield losses from Red Leather Leaf in Oats could be significantly higher than growers have previously believed.

    One reason might be that the stubble borne foliar diseases is difficult to identify. On this podcast, Agriculture Victoria research scientist, Mark McLean talks about trials currently underway and why there is strong suspicion that this disease is costing farmers yield.
