Other claims from this paper (15)
- Observation Above-root dry weight and nutrient uptake increased through growth.
- Method / resource Logistic equations described dry matter and nutrient uptake dynamics.
- Observation Dry matter accumulation rate rose early and fell after its peak.
- Observation N and K2O uptake rates changed rapidly, unlike P2O5.
- Observation Peak nutrient uptake preceded peak dry matter accumulation.
- Observation After spinning, N and P2O5 were mainly in grains while K2O was scarce.
- Observation Dry matter transference was 14.28%.
- Observation N transference was 40.41%.
- Observation P2O5 transference was 47.47%.
- Observation K2O transference was 37.04%.
- Observation Producing 100 kg grains required 1.65 kg N uptake.
- Observation Producing 100 kg grains required 0.56 kg P2O5 uptake.
- Observation Producing 100 kg grains required 1.40 kg K2O uptake.
- Recommendation The authors recommended applying all P2O5 as base manure.
- Recommendation The authors recommended split applications of N and K2O, with K2O completed before spinning.
