Aims:

To report on a summary of paddock surveys of harvest weed seed collection samples taken in 2016, 2017 and 2018 as a part of the GRDC Stubble Initiative project ‘Maintaining profitability in retained stubbles on upper Eyre Peninsula’ (EPF00001).

Aims:

Barley grass continues to be a persistent grassy weed in low rainfall farming systems and current farming practices have selected for increased seed dormancy. This change in seed dormancy has resulted in Barley grass germinating later, and being much harder to control with knockdown and pre-emergent herbicides. In 2018 a range of herbicide strat… read more

Aims:

To identify plant varieties or mixtures that can increase dry matter production of the pasture break phase on the highly alkaline soils of upper Eyre Peninsula. Current cropping and grazing systems are mostly based on monocultures and the potential feed base of the break phase could be broadened to be more productive for grazing and available fo… read more
