Initial survey of the current management practices of barley grass in upper Eyre Peninsula farming systems locations
Aims

A recent N LP2 investment, Adapting cropping systems to changing climatic conditions to reduce inputs and maximise water use through improving crop competitiveness, is a demonstration and extension project which started in late 2019. An initial grower survey of current management practices and attitudes towards barley grass was undertaken in March 2020 to be used as the baseline to assess changes in grower attitudes and changes in practices at the completion of the project. 

Key messages

The initial baseline survey received 96 responses from growers on the upper Eyre Peninsula.

68% of the grower respondents identified barley grass as having a medium to hight impact on their cropping systems

 35% of growers used some method of harvest weed seed collection and 65% did not

Current row spacings for cropping were 3% having greater than 30 cm (12") wide rows, 35% having 30 cm (12") wide rows, 21 % having 25 cm (1 0") and 31 % having 22.5 cm (9") row spacing, 10% having 18 cm (7") row spacing, and 1% having less than 18 cm row spacing.

30% of growers were using paired row or splitter systems to increase crop competition, 62% were not and 8% would like to.
