Wallendbeen NSW trials

Determine the effect of fungicide management strategies on disease control (especially crown canker blackleg, upper canopy blackleg and sclerotinia stem rot) and grain yield in HyTTec Trifecta (Resistant, Blackleg Group ABD) and 45Y28 RR (Moderately Resistant, Blackleg Group BC).

To determine optimum fungicide management for hyper yielding winter canola.

To determine optimum foliar fungicide management for hyper-yielding canola.

Individual objectives specific to the trial are:
1. Determine the value of contrasting major gene blackleg resistance groups in HYC environments:
a. BC (45Y28 RR and 45Y93 CL) – largely ineffective major gene resistance (good minor gene resistance).
b. ABD (HyTTec Trifecta) – currently effective major gene resistance.

2. Determine the effect of fungicide management strategies on disease control (upper canopy blackleg and sclerotinia), grain yield and profitability.

To assess the principal causes of erect heads at harvest in April sown wheat crops

Individual objectives specific to the trial were:
- To determine the value of BYDV tolerance in HRZ wheat crops using tolerant and non-tolerant cultivars.
- To assess the connection between erect heads and stem base disease complex e.g. crown rot, eyespot, sharp eyespot in the presence of different stem base fungicide applications.

To examine the phenology, disease resistance and standing power of new wheat germplasm sown on 20 April versus control varieties.

To examine the phenology, disease resistance and standing power of new wheat germplasm sown on 22nd April versus control varieties.

To develop profitable and sustainable approaches to disease management in high yielding and HRZ regions.
Individual objectives specific to the trial were:
- To evaluate whether newer germplasm or new fungicide chemistry allows a reduction in the number of fungicide applications whilst increasing profitability (note: reducing the number of fungicides is seen as a key measure for slowing down resistance development in cropping systems).
- Examine whether there is germplasm (varieties tested) that has sufficient early season disease resistance to replace the need for the “at sowing fungicide” and Timing 1 (T1) spray applied at GS31-32.
- To determine the cost benefit ratio of fungicide application in HRZ regions of different season lengths.

To develop profitable and sustainable approaches to disease management in high yielding and HRZ regions.

Individual objectives specific to the trial were:
- Monitor the effectiveness of fluxapyroxad (Systiva) for early disease control in wheat.
- To evaluate whether newer germplasm or new fungicide chemistry allows a reduction in the number of fungicide applications whilst increasing profitability (note: reducing the number of fungicides is seen as a key measure for slowing down resistance development in cropping systems).
- Examine whether there is germplasm (varieties tested) that has sufficient early season disease resistance to replace the need for the Timing 1 (T1) spray applied at GS31-32.
- To determine the cost benefit ratio of fungicide application in HRZ regions of different season lengths.

To assess the performance of winter and spring wheat germplasm that has shown potential in either HYC 1st stage screening or breeder’s trials with characteristics that may be suitable for regions with high yield potential. The yielded trial was grown under Hyper Yielding Crop management system with full fungicide protection (20th April sown).

To determine the response to increased crop inputs (fungicide and nitrogen) of a range of canola variety types.

To assess the performance of winter and spring wheat germplasm managed under three different levels of management (22nd April sown).

To assess the performance of winter and spring wheat germplasm managed under three different levels of management (20th April sown).

To examine the suitability of elite commercial and unreleased spring cultivars for hyper yielding regions.

To determine the response to increased crop inputs (fungicide and nitrogen) of a range of spring canola variety types.

To assess the value of pre and post GS30 defoliation in winter and spring germplasm grown in HRZ or high yielding regions of different season lengths.

Individual objectives specific to the trial were:
- Assess the dry matter offtake differences resulting from GS22, GS30 & GS32 defoliations and their effect on final harvest dry matter, grain yield and harvest index of spring versus winter wheat.
- Assess whether April sown spring wheat that has been “reset at GS32 (defoliated)” is higher yielding than GS30 and GS22 grazed and ungrazed crops.
- To assess whether the dry matter offtakes of longer season winter wheats at GS22 are more profitable (dry matter offtake and grain yield) than the same winter wheat defoliated at GS30.

To examine the suitability of elite commercial and unreleased winter canola cultivars for hyper yielding regions.

To determine the response to increased crop inputs (fungicide and nitrogen) on two commercial winter canola cultivars.

To determine optimum nitrogen nutrient management (including rate and timing) for hyper yielding spring canola.

To determine optimum nitrogen nutrient management (including rate and timing) for hyper-yielding canola.

To assess the value of higher nutrition input (N, P, K & S) for wheat in the growing season.
Individual objectives specific to the trials were:
- To assess the value of additional nutrients in the growing crop (set up as small plots at the HYC Research sites).
- To assess the value of adding increased P and K when targeting higher yield potential rather than N alone.

To assess the value of higher nutrition input (N, P, K & S) for wheat in the growing season and as an “N bank” for the following season.

Individual objectives specific to the trials were:
- To assess the value of additional nutrients in the growing crop (set up as small plots at the HYC Research sites) and for the following crop (mirror image trial set up in the host farmer’s surrounding paddock).
- To assess the value of adding increased P, K, and S when targeting higher yield potential rather than N alone.
