Wide row spacing in Arrino wheat locations
Aims

To evaluate the effectiveness of wide row spacing in Arrino wheat in a low rainfall environment with limited inputs.

Key messages
  • The main difference in yield may have been due to poor tillage in the 500mm spaced crop.
  • The entire crop was reliant on the soil nutrition from the pasutre as no fertiliser was applied to the paddock prior to and following seeding.
  • Later sowing of the trial may have jeopardised the wide row's yield capacity therefore it would be encouraged that when considering sowing in wide rows early seeding is preferable.
  • It may be noted that if nutrition was not a limiting factor for the 500mm crop, the water supply from the wide row may have increased yield to similar or better than that of the 250mm crop.
