Other claims from this paper (10)
- Intervention effect Tuber yield rose from 8.4 Mg ha‐1 at zero P to 18.0 Mg ha‐1 at 207 kg ha‐1 P.
- Intervention effect Plant P absorption rose from 5.8 to 11.8 kg ha‐1 P across the same fertilizer rates.
- Observation Average tuber P concentration was 0.20 % P.
- Observation Average top-growth P concentration was 0.24 % P.
- Association P accumulation increased with P rate.
- Association P partitioning between tuber and top growth depended on applied P amount.
- Observation Without fertilizer, P distribution between top growth and tuber was about 1:1.
- Intervention effect Increasing P rate decreased top-growth P share and increased tuber P share.
- Observation At the highest P rate, 36% of accumulated P was in top growth.
- Observation At the highest P rate, 64 % of accumulated P was in the tuber.
