Other claims from this paper (9)
- Intervention effect Intercropping reduced lodging in pea and lentil.
- Intervention effect Intercropping improved harvesting conditions of pea and lentil.
- Intervention effect At the other sites, intercropping had similar or intermediate fertilizer use efficiency relative to monocropped legumes and non-legumes.
- Observation The percentage of nitrogen derived from fixation ranged from 4.6 to 87.6 across sites, nitrogen rates and cropping systems.
- Intervention effect Intercropped legumes had significantly higher percent nitrogen derived from fixation than monocropped legumes at two sites.
- Intervention effect Nitrogen fertilization reduced percent nitrogen derived from fixation in monocropped legumes at two sites.
- Intervention effect Nitrogen fertilization did not affect percent nitrogen derived from fixation in intercropped legumes.
- Intervention effect Total nitrogen fixed was almost always lower in intercropped than monocropped systems, significantly so at two sites.
- Intervention effect Intercropped non-legumes did not show significantly lower atom percent 15N than monocropped non-legumes.
