Hazelnut

Hazelnut
Corylus spp.

A promising, low-input perennial source of food, oil, and livestock feed. Hazelnuts represent a $7 billion global market set to double in the next decade. Hazelnuts can be hand or machine harvested.

DRAINAGE:Well-drained soils
LIGHT: Full sun
ZONES: 3–8
SPACING IN A ROW:20 x 20 ft or 30 x 30 ft, thinning periodically as trees grow
YEARS TO PARTIAL/FULL BEARING: 5-10
HARVEST SEASON: September–October

Opportunities

Hazelnuts grow on a perennial shrub that mature relatively quickly for a nut crop. Researchers and farmers have been developing hazelnut plant material and cropping systems for the Eastern United States over the last several decades. Improved hybrid hazelnut cultivars have recently become available.

Challenges

The main environmental challenges in these regions are cold winters and Eastern Filbert Blight, a fungal disease that affects the European hazelnut (Corylus avellana) but not the American hazelnut (C. americana). For this reason, American hazelnut selections have been used as a source of disease resistance, as well as cold tolerance, in hybrid crosses with commercial European varieties.

Management

Hazelnuts are self-incompatible, and therefore selection of pollinators is variety specific. For this reason, care must be taken to design orchard layouts that involve inter planting of compatible varieties or seedling populations. Prune to 1-3 trunks (more trunks lead to earlier nut production). After the first or second year, pruning is needed.

Our Research

The team has planted thousands of hybrid hazelnut seedlings on research acreage at Savanna Institute’s Campus in Spring Green, WI. Unique in terms of its design and genetics, this planting will facilitate successful evaluation of yield density (using drone imagery) and machine-harvest ability (using custom-designed single plant combines).
