Advanced and new cultivation of hazelnuts is done either by hand or with mechanical and ordinary snails for collecting fallen grains.Hazelnut is widely cultivated in the gardens of Europe, Turkey, Iran and Kaoccasus.

Hazelnut seeds can be grated to any hazelnut. The hazelnut, the seed kernel, is edible and is used as raw or taffeta or flavoring. The seeds have a dark, thin, brown skin, which is slightly flavored and sometimes carved before cooking.

Turkey is the top producer, especially in the province of Gerhoson and the province of Urdu. Turkey’s hazelnut production is 625,000 tonnes, accounting for about 75% of global production. In North America, hazelnut production is concentrated in the state of Oregon.

They also widely cultivate seeds in Colombia and the United Kingdom. In 1996, skin production in the organ was about 191900 tons (18,000 tons), compared to 100 tons (91 tons) in Washington. The hazelnut in the United States is growing steadily, the Nut Marketing Association was founded in 1949 by the Federal Marketing Department 982.

Hazelnuts have also been seen on the Jababa Panghi Street in India, which they know as “trash”.

Variety of species

Variety of varieties of many types of hazelnuts include: Barcelona, ​​Butler, Cassina, Clarke, Casfred, Daviana, Del Lange, England, Anis, Philbert, Halit Jant, Jamtgard, Kent Kob, Louis, Tucoli, Tunda, Tunda Jiffoni, Tondarumana and Valencia Pride And William.

Some of these species are cultivated for certain qualities. These qualities include hazelnut size, late or premature species, or for pollination. Most commercial hazelnuts are rooted and some species are from hybrid rootstocks between hazelnut and hazelnuts.

A species grows in Washington state, “DuChilli” has a taller appearance and a thinner and shorter skin. Flavor is sweeter than other species.


Hazelnuts are harvested annually from mid-autumn. When the fall comes, trees, hazelnuts and leaves are shed. Most commercial gardeners are waiting for the seeds to fall themselves. Instead of using the equipment or shaking the tree. The first 4 pieces of equipment are used for commercial harvesting, which include: picker, pickup truck, hazel carts, cranes. The wicker moves the hazelnuts to the middle of the row. Harvesting removes hazelnuts from branches and leaves. Holds the carcass of hazel nuts, which is assembled by the pick-up, and pours the hazelnut from the carriage, pours into the tank to pack and ship, then goes to the processing stage. The sweeper is a car near the ground that passes through each row of the tree twice and has a 2 meter front belt, which rotates to sweep the leaves and remove the hazelnuts and small twigs from the left and right and in the center of the row as it is Going to go At the rear of the sweeper, a blower is powerful enough to burn the material in the next row at a speed of 90 m / s. Careful pruning during the year and bored with a sweeper can reduce the need for hand-picking the nuts. The wiper keeps a central row of hazel nuts, which is enough for the tractor to move around the center of the row without moving and driving. It is advisable to vacuum only a few rows of trees by the sweeper and the number of queues facing the reaper in time, to prevent the pickup from the hazelnuts and their breakdowns that may have fallen from the tree.

Hazelnuts may be collected up to 3 times during the harvest season, and this depends on the quantity of hazelnuts and their falling to the climate. The pick-up is a car that is driven by a tractor that removes material from the ground and separates the hazelnuts from leaves and branches.

As the pick-up moves in a row, a rotating cylinder with thousands of rounds of material moves into a conveyor. The conveyor slashed the material into a weighbridge and, under a powerful atmosphere, drops the lighter soils and separates the leaves from hazelnuts. The remaining hazelnuts are pulled with a cart attached to the pickup holder.

When a barrel of hazelnut is filled, the carrel drops the barrel and returns to the pickup. Maximize pickup until picked up. 2 Different strategies are used for collecting fallen hazelnuts. First, it’s time to be picked up and when about half of the hazelnuts fall, the pickup can quickly get nuts on the ground faster and with less chance of breaking.

The second choice is to wait for all hazelnuts to fall before landing. Although the first option looks better than the second option, the latter takes two to three times more time; of course, weather should be taken into consideration. Delayed Rainfall and a farmer must wait until all hazelnuts fall after a rainy season, making it harder to harvest.

Harvesting operations vary according to how many times it has been farmed, how much the number of scrapers, reapers, cart cars and carriages are. In a dry garden that is dusty, equipment and respiratory protective equipment should be covered. Conversely, if the ground is so wet and wet, it will humidify the device and cause the equipment to not function properly.
