Increasing weed competition with barley locations
Aims
  • To compare the competitiveness of new and existing barley varieties in the presence and absence of weeds.
  • To increase the competitiveness of a non-competitive variety through sowing time and nitrogen applications in the presence of weeds.
Key messages
  • Compass, Fathom and Scope CL were good competitors with weeds, which is consistent with previous years’ findings.
  • Hindmarsh and Spartacus CL are poor weed competitors.
  • The advantage of sowing earlier in order to increase crop competition failed to improve the competitiveness of La Trobe given the high spring rainfall.
