Other claims from this paper (9)
- Intervention effect At 79 days after planting, 25 volunteer barley plants per square metre reduced faba bean leaf area index by 41% versus no barley.
- Intervention effect At 79 days after planting, 25 volunteer barley plants per square metre reduced lupin leaf area index by 64% versus no barley.
- Observation Volunteer barley was shorter than the faba bean canopy.
- Observation Volunteer barley was taller than the lupin canopy.
- Intervention effect Volunteer barley did not affect light availability at the top of the faba bean canopy.
- Intervention effect A barley density of 25 plants per square metre reduced lupin dry matter by 68%.
- Intervention effect A barley density of 25 plants per square metre reduced faba bean dry matter by 38%.
- Mechanism The authors attribute poor lupin competitive ability to slow early leaf area development, short stature and poor light interception.
- Recommendation The authors call for early and effective control of volunteer barley in lupin crops.
