Engaging the soil at seeding with a single disc opener locations
Aims

To demonstrate the effect of seeder type and operation on the efficacy and safety of pre-emergent herbicides in barley.

Key messages
  • High operational speed reduced sowing depth of both disc and tyne openers.
  • Counts of unsprayed (nil) annual ryegrass were greater for the tyne machine than the disc seeder at 8km/h and 14km/h.
  • Within the applied herbicide treatments herbicide efficacy was fairly high. 
  • all standing stubble and poor seed placement at 8km/h and 10km/h by the tyne machine severely affected crop establishment.
  • At 14km/h the discs ability to penetrate the soil was greatly reduced, impacting sowing depth.
  • Barley yields were higher for the disc sown treatments than the tyne sown treatments.
