Duration 6 hours and 35 minutes

Keep updated on the latest developments in grains research at the Gunnedah GRDC Grains Research Update. Leading-edge research that’s farm ready for the Liverpool Plains.


  • Bridging the yield gap - how much yield do better growers on the Liverpool Plains leave behind and why? Identifying areas to capture lost yield and profit.  Zvi Hochman, CSIRO
  • Farming systems research – new data from trials at Narrabri & Spring Ridge: Gross margins and $ return/mm water from different systems.  Also; issues for sequencing cotton in dryland production systems.  Andrew Verrell & Jon Baird, NSW DPI
  • Impact of different summer crops on soil water extraction and subsequent fallow efficiency. Lindsay Bell, CSIRO
  • Soil water - methods to predict plant available water capacity (PAWC) using soil-landscape associations. Kirsten Verburg, CSIRO
  • Reserve P and K mobility and testing strategies – flood impacts on the release of P and K; what happens to fertilizer reaction products; and the effect of rhizosphere acidification on P&K mobility. Chris Guppy, UNE
  • Irrigation water quality – Soil impacts over time? What constitutes poor quality? What can be managed?  When is it better to not irrigate at all? Chris Guppy, UNE
  • Sequencing cotton in dryland farming systems – insights into getting into and out of dryland cotton.  Jon Baird, NSW DPI
  • The Helicoverpa resistance management strategy – why; what in it; how it will work?  Efficacy data of alternate products and their use at times where Altacor is not available. Repeated low-rates of NPV to suppress Helicoverpa populations. Melina Miles, DAF Qld
  • New sorghum agronomy - Pushing cold soil temperature at sowing.  Seed size and sowing depth impacts on emergence. Loretta Serafin, NSW DPI
  • Robots with lasers! - What are researchers looking at for future weed control? Lasers, robotics, microwaves, precision tillage and more. Mike Walsh, University of Sydney
