Other claims from this paper (11)
- Intervention effect Light increased weed seed germination.
- Observation In darkness, E. crus-galli germination was 85%, higher than E. colona at 70%.
- Observation Surface sowing produced 80% germination for E. colona.
- Association Weed emergence declined with increasing burial depth.
- Intervention effect Burial at 2.2 cm reduced E. crus-galli emergence by 50%.
- Intervention effect Burial at 1.4 cm reduced E. colona emergence by 50%.
- Observation No weed emergence occurred at 6 cm burial.
- Observation At equal burial depth E. colona emergence was lower than E. crus-galli emergence.
- Intervention effect Wheat residue mulch reduced emergence and aboveground biomass of both weed species.
- Intervention effect Wheat mulch inhibited E. colona more than E. crus-galli.
- Intervention effect Early deep flooding suppressed emergence, height and biomass of both weed species, especially E. colona.
