Sowing into retained pasture residue at Mount Cooper locations
Aims

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. The trial at Mount Cooper was designed to compare crop establishment and production, and weed and pest control effectiveness in the presence and absence of legume pasture residues. Project: EPF00001 Maintaining profitability in retained stubble systems - upper Eyre Peninsula.

Key messages

The 1.6 t/ha pasture residue had no impact on sowing and plant establishment in drier seeding conditions in 2014. • In 2014 there were no differences in wheat establishment, yield or grain quality due to different pre-sowing treatments with pasture residues. • The wheat stubbles have been harvested at different heights and pasture establishment and will be monitored next season.
