- Intervention effect Nitrogen application rates affected uptake, accumulation and transfer across growth stages.
- Observation Leaf nitrogen translocation amount exceeded stem by 89.18%.
- Observation Leaf translocation efficiency exceeded stem by 83.36%.
- Observation Leaf contribution to grain exceeded stem by 86.36%.
- Observation Leaf transfer supplied 47.10–57.66% of grain nitrogen.
- Observation Stem transfer supplied 22.46–30.94% of grain nitrogen.
- Intervention effect Nitrogen at 27.6 kg·hm-2 increased yield by 10.21% against no application.
- Intervention effect Nitrogen at 55.2 kg·hm-2 increased yield by 16.92%.
- Intervention effect Nitrogen at 82.8 kg·hm-2 increased yield by 15.55%.
- Observation Leaf and stem nitrogen transfer amounts, efficiencies and contributions to grain were maximal at 55.2 kg·hm-2.
- Association Apparent nitrogen recovery efficiency first rose then fell with increasing nitrogen rate.
- Association Partial nitrogen factor productivity decreased significantly as nitrogen rate increased.
- Recommendation The authors recommend 27.6–55.2 kg·hm-2 nitrogen fertilizer for dry land oil flax at the tested soil fertility.
