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.
