Other claims from this paper (19)
- Intervention effect Cereal–legume intercropping significantly reduced yield variability relative to sole crops.
- Observation Replacement-design intercropping had significantly the lowest coefficient of variation.
- Observation In tropical regions, cereal sole-crop production had higher yield variability than intercrops and legume sole crops.
- Intervention effect In tropical regions, intercropping reduced cereal sole-crop yield variability by 49%.
- Observation All cropping systems had higher yield stability in the sub-tropical region.
- Association Higher production yield levels were associated with higher yield stability.
- Intervention effect Nitrogen fertilizer had no strong effect on intercrop yield.
- Intervention effect Nitrogen fertilizer significantly increased barley grain yield.
- Intervention effect Nitrogen fertilizer significantly increased barley biomass yield.
- Intervention effect Nitrogen fertilizer reduced pea yield.
- Intervention effect Nitrogen fertilizer significantly reduced land-equivalent-ratio values.
- Mechanism Available soil nitrogen was interpreted as decreasing complementarity between intercrop components.
- Observation Coefficient of variation did not differ significantly between cereal sole crops and intercrops.
- Association Intercropping with a higher pea proportion had higher grain-yield stability.
- Association Intercropping with a higher pea proportion had higher biomass-yield stability.
- Observation The authors concluded that cereal–legume intercropping improves yield.
- Observation The authors concluded that cereal–legume intercropping improves yield stability.
- Recommendation The authors suggested cereal–legume intercropping could improve food security and livelihoods.
- Recommendation The authors recommended intercropping practice as a step toward agroecosystem sustainability.
