Trial location(s) Minnipa, SA
Row direction and stubble cover locations
Aims

To investigate the effects of row direction, row spacing and stubble cover on grain yield and quality.

Key messages
  • E-W sowing direction yielded 0.24 t/ha higher than N-S on 18 cm row spacing in the 2009 season, despite consistent trends in the opposite direction over the last 4 years.
  • Burning stubble (2005-08) yielded 0.2 t/ha higher than retained stubble at 3 t/ha, and had higher protein levels, also an opposite trend to previous years.
  • Rhizoctonia was similar in all stubble treatments.
