Millicent SA trials

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

Individual objectives specific to the trial are:
- To determine the value of Barley Yellow Dwarf Virus (BYDV) tolerance in HRZ wheat crops using a tolerant (cv Manning) and a non-tolerant (cv RGT Relay) cultivar.
- 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 develop profitable and sustainable approaches to disease management in HRZ barley. 

To develop profitable and sustainable approaches to disease management in HRZ wheat – winter and spring wheat sown 21 April.

Individual objectives specific to the trial were:
- To monitor the effectiveness of flutriafol in furrow 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 value of higher nutrition input (N, P, K & S) for wheat in the growing season (cv RGT Accroc).

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 Research Centre) .
- To assess the value of adding increased P, K, and S when targeting higher yield potential rather than N alone.

To examine the suitability of elite commercial and unreleased winter canola cultivars for Hyper-yielding regions

The project established, assessed and demonstrated a research programme that has resulted in the demonstration of best management IDM practices for the control of Septoria tritici blotch (STB) in the southern region HRZ.

Are we better to increase seeding rate and reset phenology in faster spring Barley sown early to capitalize on root growth, greater carbohydrate reserve, and initiate more tillers rather than utilise current winter germplasm options sown early in the HRZ? Is spring barley more sensitive to changes in plant density than winter barley?

Individual objectives specific to the trial are:
- Assess whether growers are currently under fertilizing barley crops in the region and N requirements required to reach target yields of 10 – 12 within each region.
