- •
A set of sink and source indicators was assessed at sunflower harvest.
- •
Oil and protein seed concentrations and contents were related to these indicators.
- •
Sinks and sources were manipulated by N-fertilization, plant density and genotype.
- •
Plant density had a positive effect on nitrogen uptake after flowering.
- •
Oil concentration was related to biomass remobilization.
- •
Genotype with highest protein concentration was the same regardless of management.
- •
Genotype with highest oil concentration changed with plant density and N-fertilization.
