Seeding into stubble - a comparison of seeding systems, pre-emergent 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.
