- For the fourth year running, on-row sowing proved it has potential as a brome management tool on non-wetting sands, reducing brome grass seed set by 55%.
- The use of trifluralin with metribuzin reduced the brome density in July but did not reduce seed set.
- On-row sowing resulted in more soil water and nitrogen supply potential near the crop, improved crop establishment and higher crop biomass.
- On-row sowing did increase root disease incidence, but there were low levels of disease for both on- and inter-row sowing in 2017.
