Barley grass management in retained stubble systems - farm demonstrations

The GRDC ‘Maintaining profitable farming systems with retained stubble - upper Eyre Peninsula’ project aims to improve farm profitability while retaining stubble in farming systems on upper Eyre Peninsula (EP). Weed control in stubble retained systems can be compromised where herbicide efficacy is limited due to higher stubble loads, especially for preemergent herbicides. Current farming practices have also changed weed  behavior with later germinating barley grass genotypes now present in many paddocks on the Minnipa Agricultural Centre (MAC) (B Fleet, EPFS Summary 2011). Several MAC farm demonstrations  were undertaken in 2014 to address barley grass weed issues including later germinating types and barley grass resistance to Group A herbicides. An integrated approach to weed management aimed at lowering the weed seed bank can make use of diverse techniques such as cultivation, stubble burning, in-crop competition using higher sowing rates and possibly row orientation. The weed seed bank can be reduced within the break phase by hay making, or green or brown manuring. Other techniques used effectively in WA on ryegrass and wild  radish have been narrow windrows and chaff carts. However there is limited information on the effectiveness of these tactics on barley grass in part because it is believed that most seed is shed well before harvest, limiting control. In 2015 the monitoring of farm paddock demonstrations in low rainfall farming systems to  assess control methods for grass weeds, mainly targeting barley grass, were undertaken by;
• Monitoring of narrow windrows in MAC paddocks N1 and N6W, and Bruce Heddle’s paddock CE42 (windrows and chaff dumps).
• Spray topping after oat and vetch hay (MAC paddock S4) using both crop competition (high seeding rate) followed by spray topping after the hay cut.

COGGO Snails 2020 demonstration

The aim of this trial is to determine and demonstrate if stubble management treatments can lead to a reduction in conical snail numbers.

The trial is based on techniques used in SA where snails on the stubble are knocked to the ground on to days (35 deg +) where they dehydrate and die. 

The trial tested and analysed the effectiveness of three techniques- speed-tilling, cableing and stubble crunching on snail mortality.  

This trial aims to provide growers with a clear percentage of the effect of three stubble management techniques (cabling, stubble crunching and speed tillage) on small conical snail mortality.  

Introduce more ‘tools’ into growers’ repertoire to control snails & reduce reliance on snail baiting. 

Demonstrate the effectiveness of ‘GrainCam’ to identify snail hot spots in paddocks and map their distribution for targeted future management.

Establishing pasture into heavy stubble at Mount Cooper

The GRDC project ‘Maintaining profitable farming systems with retained stubble - upper Eyre Peninsula’ aims to produce sustainable management guidelines to control pests, weeds and diseases while retaining stubble to maintain or improve soil health, and reduce exposure to wind erosion. The major outcome to be achieved is increased knowledge and skills allowing farmers and advisers to improve farm profitability while retaining stubble in farming systems on upper Eyre Peninsula (EP).

 

One issue Mount Cooper farmers identified as an issue was the establishment of self-regenerating medic pastures into heavy stubble residues. The trial reported here was designed to compare medic establishment and production, with different management strategies imposed on the previous crop stubble residues.

The GRDC project ‘Maintaining profitable farming systems with retained stubble - upper Eyre Peninsula’ aims to produce sustainable management guidelines to control pests, weeds and diseases while retaining stubble to maintain or improve soil health, and reduce exposure to wind erosion. The major outcome to be achieved is increased knowledge and skills allowing farmers and advisers to improve farm profitability while retaining stubble in farming systems on upper Eyre Peninsula (EP).

One issue upper EP farmers identified as a problem was sowing into retained pasture residue with pasture vines causing issues with blockages at sowing and uneven germination. Also establishing legume pastures into heavy stubble residues has also an issue in this region. The trial at Mount Cooper was designed to compare plant establishment and production, and weed and pest control effectiveness in the presence and absence of previous crop or legume pasture residues.
