Trial location(s) Birchip, VIC
Wheat canopy management trial - Mallee locations
Aims
  • To look at canopy management and its interaction with disease management in the different climates of southern Australia.
  • To examine how the crop canopy was influenced by nitrogen rate and timing in the Mallee environment.
Key messages

On a site with high N at sowing, yields of 2.0-205t/ha were achieved and there was no apparent benefit from N applications of 30 and 60kg N/ha, thus all applied nitrogen treatments lost money relative to the zero nitrogen plots.
