To trial and demonstrate two possible agronomic adaptations to a changing climate:

• to sow wheat varieties earlier to reduce the possibility of heat shock events during grain fill whilst taking into account the frost risk, and
• to sow more than one variety in the one paddock as a mix to ensure that the whole crop is not susceptable to frost and heat shock at the same time.

The GRDC Stubble project aims to improve farm profitability while retaining stubble in farming systems on upper Eyre Peninsula (EP). Weed control in stubble retained systems is an issue with reduced herbicide efficacy due to higher stubble loads especially for pre-emergence herbicides. Current farming practices have also changed weed behaviour with later germinating barley grass genotypes now being present in many paddocks on Minnipa Agricultural Centre (MAC) (B Fleet, EPFS Summary 2011, p 177). As a part of the stubble project 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 within the farming system. 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 seed bank of crop weeds can be reduced within the break phase by hay making, or green or brown manuring. Other techniques used effectively in WA with ryegrass and wild radish have been narrow windrows and chaff carts, however little research has been done on the effectiveness of these approaches with barley grass because of its early shedding of seeds before harvest.
