Seeding into stubble - Trial 1: a comparison of seeding systems, preemergent herbicides and stubble height in barley locations
Aims

To investigate the effect of full stubble retention compared with other stubble management methods and seeding technologies.

Key messages
  • Hindmarsh barley grain yield was unaffected by stubble or seeding systems averaging 3.3 t/ha.
  • Of all pre-emergent herbicides trialled a grain yield reduction was observed for Sakura (average reduction 0.18 t/ha). A split application of Boxer Gold (IBS/POST) was slightly safer compared to the full rate IBS.
