till farming system

Catalogue: GRDC Updates
Optimising barley yields and quality in No-Till farming systems.. X Highest yields generally occur with row spacing narrower than 300 mm and the benefits of adopting wider row spacing need to be evaluated against the costs (in terms of lower yields)... At one site, there was a strong correlation between the variety ranking in terms of trifluralin effects on plant establishment and the ranking of varieties in terms of the effect of wide row spacing on plant establishment, suggesting the observed "tolerances" are more related to (unidentified) seed quality issues rather than genetic differences between the varieties...
