Row direction, row spacing and stubble cover effects locations
Aims

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

Key messages
  • Mean grain yield has been 8.4% higher with north-south over east-west sowing over the last four seasons.
  • Grain yield has been higher with narrower row spacings when stubble has been retained.
