Intervention effect Plant lodging in heritage wheat cultivars was 21.5% lower at low sowing density.
Intervention effect Weed biomass increased at low sowing density in heritage wheat crop stands.
Intervention effect Weed biomass increased at low sowing density in modern wheat crop stands.
Association Heritage wheat crop stands had 56% lower weed biomass on average than modern stands.
Association At low sowing density, heritage wheat stands had weed biomass of 6.82±1.50 g m–2, lower than modern stands.
