Break crop selection for Eyre Peninsula low rainfall farming systems locations
Aims

The aim of this research is to identify the best break crop options for different climate, soil type and biotic stress situations within major cropping regions of the southern low rainfall zone.

Key messages
  • Field pea had higher biomass and grain yield production than other break crop species at Minnipa, although @RISK analysis suggests field pea is only profitable as a grain crop in 41% of years.
  • @RISK analysis model outcomes indicate chickpea, vetch hay and lentil are lower risk break crop species, and are profitable in more than 50% of years.
  • Field pea and vetch have multiple alternative end-use options in dry seasonal conditions that can be utilised to recover crop input costs and salvage a financial return.
