To provide farmers in the Facey Group grower region with new options for sustainable grazing and summer pasture species. Growers have identified the need for drought tolerant summer grazing options rather than traditional options more suited to higher rainfall zones. This trial aims to compare tedera to the more commonly used annual pasture species – annual ryegrass, serradella and subterranean clover to fill the summer and autumn feed gap.

• Conduct 197 in-paddock surveys in both 2019-20 and 2020-21 to identify the composition of summer weed species present across the GRDC Western region covering the 6 eco-agricultural zones.

• better inform possible future initiatives on identification and management of summer weeds

To optimise cereal protein by better understanding response to high nitrogen rates in a given season through demonstration trials while also better understanding disease response.

This GRDC investment aims to look at the impact of summer cropping on waterlogged winter soils and the resultant impact on crop growth and yield in the next winter growing season. Stirlings to Coast Farmers member Steve Lynch has been growing summer crops for the sole purpose of drying his soil profile in the summer to reduce the risk of waterlogging in the winter-time. Without livestock to benefit from the summer feed, Steve still believes the reduced risk of water-logging is a tangible benefit to his winter crop yields as well as providing diversity into the cropping system. Simon Harding’s (Williams demonstration host) intentions with the summer crop was to reduce his waterlogged areas within his farming practice. The area chosen suffers severe winter waterlogging that impacts on winter crop production and profitability.
