Other claims from this paper (10)
- Intervention effect Increasing sowing density decreased weed biomass in winter wheat.
- Intervention effect The uniform spatial pattern gave 23% lower weed biomass than rows in winter wheat.
- Intervention effect The uniform spatial pattern gave 14% higher grain yield than rows in winter wheat.
- Intervention effect In rows, increasing sowing density decreased weed biomass by 27% and 38%.
- Intervention effect In the uniform pattern, increasing sowing density decreased weed biomass by 36% and 50%.
- Intervention effect With herbicide weed control, increasing sowing density had no influence on winter wheat grain yield.
- Observation Field poppy had the largest weed biomass and the largest impact on winter wheat yield.
- Observation Canola had the lowest weed biomass and the least impact on winter wheat yield.
- Observation Weed biomass comprised 30% of total crop plus weed biomass in the first year.
- Observation Weed biomass comprised only 5% of total biomass in the second year.
