Long-term comparison of stubble management strategies locations
Aims

To compare the long term effects of different stubble treatments on crop establishment, growth, grain yield and quality. The sustainability of treatments will also be evaulated with comparison of soil physical, chemical and biological data.

Key messages
  • Five stubble managmenet strategies were compared: fully retained; fully retained with higher sowing rate; cut and baled; burnt and incorporated with Lemken discs.
  • Fully retained stubble resulted in some soil improvements such as increased worm populations.
  • Grain yield from plots where stubble was retained (fully retained ad cut and baled) tended to produce higher yields compared with plots where stubble was burnt. The wet season and irrigation may have masked any greater potential yield benefits from plots with retained stubble.
