- <p id="par0005">Variation in the yield-to-N uptake relationship was corresponded more with changes in N harvest index (NHI) rather than seed N concentration.p>
- •
- <p id="par0010">N, P and K HI and seed HI relationship were well explained using specific-organ nutrient concentrations in seed and stover.p>
- •
- <p id="par0015">Phosphorus and N presented similar nutrient HIs: seed HI relationship but potassium followed a differential nutrient partitioning dynamic.p>
- •
- <p id="par0020">Variations in nutrient stoichiometry, represented as the N:P and N:K ratios, were primarily related to changes in the stover nutrient concentration.p>
