Mariateresa Lazzaro; Ambrogio Costanzo; Dalia Hosam Farag; et al. Italian Journal of Agronomy 2017. doi:10.4081/ija.2017.901

Other claims from this paper (8)

Intervention effect Single cultivars and mixtures did not differ significantly in grain yield and weed suppression.
Intervention effect At low versus high sowing density, grain yield increased 15.6% in heritage wheat cultivars.
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.
