Other claims from this paper (13)
- Association Plant nutrient contents at maturity responded predominantly to N rate.
- Observation Relative nutrient content at silking compared with maturity was 47% for P.
- Observation Relative nutrient content at silking compared with maturity was 100% for K.
- Observation Relative nutrient content at silking compared with maturity was 58% for S.
- Observation Equivalent stoichiometric ratios were documented for N and S partitioning in leaf, stem and ear components.
- Intervention effect Plant density and N rate treatments did not modify P, K and S partitioning to plant components during vegetative or reproductive periods.
- Association N rate affected leaf vs. stem P partitioning.
- Observation Near silking, relative nutrient partitioning to the ear followed the order P > S > K.
- Mechanism The ear partitioning order mimicked the harvest indices at maturity, suggesting genetic modulation.
- Association N rate influenced whole-plant nutrient ratios through N content changes.
- Association Plant density did not influence whole-plant nutrient ratios of N to P, K and S.
- Association As the season progressed, plant density and N rate changed the absolute P, K and S quantities.
- Association As the season progressed, plant density and N rate had little influence on nutrient ratios.
