Wide Row Spacing and Rigid Ryegrass (Lolium rigidum) Competition Can Decrease Barley Yield

Blakely H. Paynter Weed Technology 2010. doi:10.1614/wt-d-09-00062.1

Other claims from this paper (9)

Observation The four barley cultivars differed in grain yield.
Intervention effect Doubling row spacing decreased barley grain yield at three of four sites.
Intervention effect The row-spacing impact on yield was greater at 48 or 50 cm than at 36 cm.
Intervention effect Rigid ryegrass competition reduced barley grain yield at two of four sites.
Association The weed competition effect on barley yield was the same at narrow and wide spacing at both locations.
Association At one location cultivar modified the weed competition impact.
Intervention effect Wide barley rows increased rigid ryegrass biomass production.
Intervention effect Wide barley rows increased rigid ryegrass tiller number.
Recommendation The authors warn that spacing above 25 cm is likely to raise weed productivity unless integrated weed management is applied.
