Other claims from this paper (12)
- Observation Early rice had one nitrogen uptake peak at tillering to jointing, about 60% of total uptake.
- Observation Late rice had a nitrogen uptake peak at booting earing representing 24% of total uptake.
- Observation Early rice absorbed phosphorus and potassium largely from tillering to milky stage.
- Observation Late rice had one phosphorus and potassium uptake peak at tillering, exceeding 55% of total uptake.
- Association Two line hybrid rice strains accumulated 21% more dry matter than other varieties.
- Association Two line hybrid rice strains yielded 46% more grain than other varieties.
- Association Two line hybrid rice strains yielded 32% more straw than other varieties.
- Association Late rice surpassed early rice in dry matter accumulation and grain and straw yield.
- Association Late rice had higher grain yield than early rice at the same phosphorus or potassium uptake.
- Association Rice grain yield was positively correlated with nitrogen uptake at all growth stages.
- Association Rice grain yield had no correlation with phosphorus or potassium uptake during reproductive growth.
- Mechanism The authors interpreted reproductive phosphorus and potassium uptake as luxury consumption.
