- Association Competition influenced primary wood growth and productivity.
- Intervention effect The densest spacing had the lowest content for almost all soil nutrients.
- Association Higher density increased competition index.
- Intervention effect Higher density produced fewer stems from stools.
- Intervention effect Higher density produced smaller stem diameters.
- Intervention effect Higher density lowered biomass productivity.
- Association Competition index rose with plant age.
- Intervention effect Coppice development increased productivity by up to 15%.
- Observation The optimum treatment yielded 7.2 kg primary wood biomass per tree.
- Observation The optimum treatment yielded 8.22 kg coppice wood biomass per tree.
- Observation The treatment produced approximately 22% lignin content.
- Observation The treatment produced calorific value around 18,807 kJ.
- Intervention effect Harvest at 24 months did not significantly increase productivity.
- Intervention effect Harvest at 24 months did not significantly increase lignin content.
- Intervention effect Harvest at 24 months did not significantly increase calorific value.
