Wheat yield and quality in Western Australian sandplain farming systems locations
Aims

To explore the yield potential for wheat in the northern sandplain region and to identify the main constraints to achieving this potential.

Key messages
  • Despite the late sowing, wheat yields were reasonable. The hightest yield was for wheat after canola with ripping. With 80kg N/ha, this was 3.1t/ha.
  • The benefit of ripping had decreased markedly from the previous season.
  • The canola rotation increased wheat yield by about 0.5t/ha. It was greater with ripping.
  • The main conclusion from this experiment is that on this soil type, potential yields can be obtained with management tools already available to growers.
