Making the most of summer rainfall locations
Aims

To demonstrate how managing paddock stubble load and weed burden (paddock surface conditions) during summer can affect subsequent crop yield.

Key messages
  • Allowing weeds to grow during summer reduced subsequent wheat yield by more than 50 percent
  • Provided summer weeds were controlled, other surface treatments (slashed stubble, standing stubble, cultivation, bare earth) had little effect on crop yield
  • Controlling summer weeds is one of the most cost-effective input investments available to growers in the Mallee, returning $5 for every $1 invested in this demonstration.
