Other claims from this paper (15)
- Observation Common lambsquarters dominated midseason weed biomass in potato.
- Intervention effect In 1991–1992, conventional management had the least weed biomass.
- Intervention effect In 1991–1992, weed biomass did not differ between RI and BIO systems.
- Intervention effect In 1993, RI and conventional systems suppressed weeds below BIO levels.
- Intervention effect Soil management had no effect on weed biomass during 1991–1993.
- Association Soil management affected weeds in BIO during 1994 and 1995.
- Intervention effect Amended soil management lowered weed biomass by 77% in 1994.
- Observation No significant weed-related yield loss was detected in the 1994 BIO system.
- Observation Weed-related yield loss in 1995 was 37% under unamended soil management.
- Observation Weed-related yield loss in 1995 was 12% under amended soil management.
- Association Soil management effects in the 1994 BIO system carried into the following season’s germinable seed bank.
- Observation Germinable common lambsquarters seed density in 1995 BIO was 4,082 m −2 under unamended management.
- Observation Germinable common lambsquarters seed density in 1995 BIO was 1,280 m −2 under amended management.
- Mechanism The authors suggest organic amendments and green manure promote a potato crop better able to compete with weeds.
- Recommendation The authors recommend organic amendments and green manure as components of integrated weed management with minimal herbicide reliance.
