As an independent service to our members, we also provide trial design and data collection services for farmers wanting to undertake their own trials in a more scientific manner. Please contact Bronwyn Copestake via for more information.

Which Wheats for When?

Canola Time of Sowing to Maximise Yields in Your Area

Chaf Carts as Sheep Management Tools

To determine the appropriate sowing time by variety combination to maximise the grain yield and quality of wheat in different environments in Western Australia.

The optimum sowing window was defined as the sowing period that achieves on average more than 95% of the maximum yield for each cultivar type. Simulation of yield penalties due to frost and/or heat stress is still under development.

Demonstrate that chaff carts can benefit sheep enterprises by increasing sheep condition and reducing supplementary feed costs, impacting overall farm productivity and profitability, and foster a better understanding of the use of chaff carts and other sheep management tools such as condition scoring.

Soil Wetting Agents Used to Manage Water Repellence can Benefit Crops for More Than One Season Though Highest Yields Result From Annual Applications

Agronomic Options to Overcome Soil Water Repellence and Improve Crop Performance Regardless of Sowing Conditions

Managing Crop Grazing for On-Farm Profitability

Two small plot research experiments were established in 2016 at Darkan and Kojonup to investigate the longevity of banded soil wetting agents in duplex sandy gravel and loamy gravel soils in South-West Western Australia. The experiments were designed to test residual or additive effects of the soil wetters by either applying or excluding them in different years to achieve different cumulative rates over the length of the trial.

Soil water repellence (SWR) is a significant constraint to crop establishment in South-West Western Australia (WA). A long-term agronomic experiment commenced in 2015 to investigate a range of potential amelioration and mitigation options to manage SWR.

Demonstrating the advantages of crop grazing on farm profitability and enhance producer understanding of how to apply the tool to best advantage in different seasons and situations.
