DECISION SUPPORT TOOLS

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.

Deep ripping, 'deeper' deep ripping and water use efficiency
  • OBJECTIVE 1: For growers, researchers and advisers to have a better understanding of the costs and benefits of ‘deeper’ deep ripping versus standard deep ripping and in particular depth of deep ripping required to optimise crop yield and profit.
  • OBJECTIVE 2: To gain a better understanding of whether the higher cost associated with deeper ripping is matched with a corresponding yield increase taking into account the rainfall zones and the soil type.
  • OBJECTIVE 3: Assess how long the benefits of ‘deeper’ deep ripping benefit last in a CTF system.
  • OBJECTIVE 4: Enable growers and advisors on behalf of their clients, assess the cost-benefit of undertaking ‘deeper’ deep ripping.

Demonstrating integrated weed management strategies to control barley grass in low rainfall zone farming systems

Barley grass possesses several biological traits that make it difficult for growers to manage it in the low rainfall zone, so it is not surprising that it is becoming more prevalent in field crops in SA and WA. A survey by Llewellyn et al. (2015) showed that barley grass has now made its way into the top 10 weeds of Australian cropping in terms of area infested, crop yield loss and revenue loss.

The biological traits that make barley grass difficult for growers to manage in low rainfall zones include:

  • early onset of seed production, which reduces effectiveness of crop-topping or spray-topping in pastures,
  • shedding seeds well before crop harvest, reducing harvest weed seed control effectiveness compared to weeds such as ryegrass which has a much higher seed retention,
  • increased seed dormancy, reducing weed control from knockdown herbicides due to delayed emergence, and
  • increasing herbicide resistance, especially to Group A herbicides, used to control grass weeds in pasture phase and legume crops.

 

Barley grass management is likely to be more challenging in the low rainfall zone because the growing seasons tend to be more variable in terms of rainfall, which can affect the performance of the pre-emergence herbicides. Furthermore, many growers in these areas tend to have lower budgets for management tactics, and break crops are generally perceived as more risky than cereals. Therefore, wheat and barley tend to be the dominant crops in the low rainfall zone. This project is undertaking coordinated research with farming systems groups across the Southern and Western cropping regions to demonstrate tactics that can be reliably used to improve the management of barley grass.
