- Intervention effect Integrated nitrogen biofertilizer raised sunflower seed oil concentration significantly in both years.
- Intervention effect Integrated nitrogen biofertilizer raised sunflower seed fatty acid composition significantly in both years.
- Intervention effect Integrated nitrogen biofertilizer raised sunflower harvest index significantly in both years.
- Observation NECPI produced the greatest effects on NYE, NUE and NPE.
- Observation NECPI produced the greatest effect on photosynthetic N use efficiency.
- Association Treatment by year interaction significantly affected linoleic and linolenic acids.
