Other claims from this paper (11)
- Observation Poppy yield ranged from 798.7 to 1293.1 kg ha−1.
- Intervention effect White clover intercropping had no significant effect on poppy yield versus sole cropping.
- Intervention effect White clover intercropping did not significantly change poppy dry matter, height or leaf area index.
- Intervention effect White clover intercropping did not significantly change poppy C/N ratio.
- Observation Poppy-barley intercrop yields were higher in 2018 and 2020 than 2019.
- Observation The poppy-barley intercrop had higher land equivalent ratios in 2018 and 2020 than 2019.
- Mechanism Differences in seeding dates, precipitation and nutrients chiefly explained year differences.
- Intervention effect Barley seeding density had a small effect on intercrop performance.
- Recommendation The authors advise seeding poppy before barley to limit competition.
- Recommendation The authors conclude poppy and white clover can be sown together.
- Recommendation The authors consider carefully managed poppy intercropping promising for reducing total yield-loss risk.
