The project objectives were to: determine what effect stubble load and type had on YLS infection. Determine whether changing cultural practices would aid in reducing YLS incidence. Investigate the effect of fungicide application timing and nutrition on YLS severity.

To investigate wider range of fungicides for yellow leaf spot control.

To investigate wider range of fungicides for yellow leaf spot control.

Regional specific agronomy has been identified as a need by growers in RCSN Open Local Forums, in particular in using regional specific agronomy demonstrations to assist decision making of growers.

The aim of this project was to use best district practice to examine if newer varieties respond differently to increasing nutritional inputs and whether this can be exploited by growers.

This was done by measuring crop performance with different sowings times and nutrition regimes, representing different decision-making scenario's depending on budget and seasonal rainfall.

This information should then assist grower’s decisions with variety specific agronomic management.

To use whole farm soil mapping to rationalize the farm fertilizer programme.

To compare three N products for topdressing nitrogen onto wheat.

To investigate the response to nitrogen fertiliser on wheat.

To examine the potential for crop yield in the northern sandplain systems and explore practices that will allow the potential to be approached.

To examine the potential for crop yield in the northern sandplain systems and explore practices that will allow the potential to be approached

This trial is apart of a three year GRDC project to develop a benchmark to be used to accurately determine crops' N status.

The aim of this years trial is to determine how a crops’ N status changes in relation to early sowing and variety.

The aim of these trials was to compare existing wheat varieties under dryland and irrigated conditions, evaluate new breeding material and continue to assess the disease responses of all germplasm.
