Other claims from this paper (8)
- Observation After 3 years, seed density of spring/summer weeds was reduced in all treatments.
- Intervention effect Triticale had the lowest weed seedbank density (9,487 seeds m-2) compared with weedy fallow (28,543 seeds m-2).
- Intervention effect Stochastic analysis showed a lower risk of enlarging weed seedbanks in TRIT than in WF.
- Observation Seed density of Portulaca oleracea was reduced by 90 % by the end of the study.
- Observation Seed density of Chenopodium album was reduced by 80 % by the end of the study.
- Intervention effect Autumn/winter and indifferent weed seed densities increased 4.2 times more in WF and RCM than in TRIT.
- Intervention effect Fallow periods between cash crops may increase weed species linked to that season.
- Recommendation Introducing cover crops can mitigate this effect, although the choice of cover crop species may influence its extent.
