The relationship between weed populations and cereal crops following nine organic break crops was investigated in field trials in Warwickshire, Aberdeenshire and Ceredigion in 2001. Weed biodiversity was high on all sites and varied between sites in terms of species present. Severity of weed infestation differed significantly between sites and between cereals following different break crops. The impact of break crop species on the incidence and severity of the weed burden in the following cereal is discussed in relation to the field trials at the three sites.</mods:abstract><mods:classification authority="lcc"> Weed management</mods:classification><mods:classification authority="lcc">   Farming Systems</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2002</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Organic Centre Wales, Institute of Rural Studies, University of Wales Aberystwyth</mods:publisher></mods:originInfo><mods:genre>Conference paper, poster, etc. </mods:genre></mets:xmlData></mets:mdWrap></mets:dmdSec><mets:amdSec ID="TMD_oai:orgprints.org:8408"><mets:rightsMD ID="rights_oai:orgprints.org:8408_mods"><mets:mdWrap MDTYPE="mods"><mets:xmlData><mods:useAndReproduction>
