Variety traits
Corylus avellana L.
Hazel productivity is a key trait determining a plant's ability to produce a nut yield, measured by the mass of fruit per bush or relative indicators per unit of crown volume.
In the reference 26 varieties crop Common hazel, where this is mentioned in the description.
To assess hazel productivity, direct per-bush nut mass accounting is used, as well as biometric indicators such as yield calculation per unit of crown volume, crown projection area, or trunk cross-sectional area. Assessment per unit of crown volume is considered the most objective and stable.
Yield levels vary significantly depending on growing conditions. In natural forest environments, productivity ranges from 0.05 to 1.5 kg per plant, reaching 2.6 kg in favorable forest types. In open areas, this figure increases to 2–4 kg, while in cultivated varieties (hazelnuts), it amounts to 3–8 kg per plant.
