To determine the impact of inoculum loads of STB on wheat grain yield and quality.

To improve lentil establishment, biomass production and yield by soil amelioration and or lime application on Mallee sands

The objective of the four small plot trials is to provide statistically sound data that will inform farmer and consultant decision making in years of early waterlogging, where they are considering late sown cereals as an option. The trials will be professionally implemented and managed by industry best practice standards to ensure the data is reliable. The implementation of four trial sites also ensures the data generated is locally relevant to farmers right along the South Coast of WA.  

GRDC Project Outcome:

By March 2024, All Western Region growers and advisers will have access to trial information on late winter to early spring sown cereals (wheat and barley) on the south coast of WA to assist in making educated decisions to sow at this time when waterlogging presents and cereal crops cannot be sown at the traditional time or for other reasons that may present for a later sowing opportunity such as weed issues or poor crop establishment.

To improve knowledge of Rosinweed and Star of Bethlehem biology in grain growing regions of western Victoria and collect preliminary evidence of effective control options for further validation and extension.

This project aims to demonstrate a range of management strategies for disease complexes as they arise, including plot trials at two locations assessing genetic plant resistance, fungicide and other management strategies in wheat, barley and lentils, and up to four responsive in paddock trials across the subregions, if and where need arises. Trials are aimed to support facilitated discussion and peer to peer learning around key disease management decisions.
