Other claims from this paper (6)
- Association Volunteer barley caused severe pea yield losses at both locations.
- Association Pea yield loss per volunteer barley plant was 1.7% at Vegreville.
- Association Pea yield loss per volunteer barley plant was 5.4% at Lethbridge.
- Observation Volunteer barley seed revenue partly offset monetary losses from reduced pea yield.
- Observation Pea density effects on pea and volunteer barley yields were inconsistent and marginal.
- Recommendation The authors found little advantage to sowing pea above 100 plants per square metre.
