• To study timing of post-flowering applications of desiccants on
  1. sterilisation of developing ryegrass seeds and
  2. seed-filling, development and yield of range of field pea varieties.
• The objective is to time a single “crop-topping” spray to kill all developing ryegrass seeds and at the same time desiccate the field pea crop with minimal or no loss of yield or seed size.

The aim of this experiment was to determine the Critical Growth Period (CGP) of field-grown canola so that sowing date and variety can be selected to ensure that the CGP (the period when the crop is most sensitive to environmental stresses) occurs when the growing environment is likely to be the most favourable (a balance between adequate moisture, heat and frost stress, and adequate solar radiation).
 

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).

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 evaluate dryland dual-purpose canola varieties in the high rainfall zone (HRZ) (>550 mm) of the south-east of South Australia (SA).

This project aims to evaluate dryland dual-purpose canola varieties in the high rainfall zone (HRZ) (>550 mm) of the south-east of South Australia (SA).

This project is being carried out in the Upper South-East region to assess various Decision Support Tools and the role that they can play in improving the uptake of conservation tillage, and more efficient nitrogen management. It aims to look at 2 different “Decision Support Tools”; Yield Prophet – a computer model, and Soil Moisture probes to assess their role in conservation agriculture, and to
better understand what is happening under the soil in minimum till systems.

This project is primarily about understanding more about the size of the water bucket (Plant Available Water as a crop input),
and how that may impact our management decisions and the final result of our crops for the season.
