Also, the capsule makes the harvest more complicated and even painful for the worker. 2 By hand with nets: This technique is less time-consuming and protects the fruits from injuries. However, setting up the nets is work intensive. 3 Mechanical: The fruits are collected with a machine that works similarly to a vacuum cleaner. Doing so is time-saving and economical, but it's possible that some fruits get injured, and a big initial investment is needed. Furthermore, a visual sorting is not possible.

Overview
History
It has been a staple food in southern Europe, Turkey, and southwestern and eastern Asia for millennia, largely replacing cereals where these would not grow well, if at all, in mountainous Mediterranean areas. Evidence of its cultivation by man is found since around 2000 BC. Alexander the Great and the Romans planted chestnut trees across Europe while on their various campaigns. A Greek army i…
Etymology
The name "chestnut" is derived from an earlier English term "chesten nut", which descends from the Old French word chastain (Modern French, châtaigne). The French word in turn derives from Latin Castanea (also the scientific name of the tree), which traces to the Ancient Greek word κάστανον (sweet chestnut). A possible source of the Greek word is the ancient town of Kastanea in Thessaly. …
Description
Chestnut trees are of moderate growth rate (for the Chinese chestnut tree) to fast-growing for American and European species. Their mature heights vary from the smallest species of chinkapins, often shrubby, to the giant of past American forests, C. dentata that could reach 60 m. Between these extremes are found the Japanese chestnut (C. crenata) at 10 m average; followed by th…

Fresh chestnut fruits provide about 820 kJ (200 kcal) of food energy per 100 g of edible parts, which is much lower than walnuts, almonds, other nuts, and dried fruit (about 2,500 kJ or 600 kcal per 100 g).

Cultivation, pests, and diseases
Chestnuts produce a better crop when subjected to chill temperatures during the dormant period. Frosts and snowfalls are beneficial rather than harmful to the trees.

Chestnut is hardy to USDA zone 5, which is −29 °C (−20 °F) lower in average minimal temperature than London in zone 9. The young growth in spring, even on mature plants, however, is frost-tender; bud-burst i…

Cultivation
Three different cultivation systems for the sweet chestnut can be distinguished:
• Coppicing: Mainly for wood extraction. Standard conditions yield 15 m wood per ha and year.
• Selve: Fruit production from grafted trees. The trees have a short tribe and a big crown. Trees have a high density and the ground between the trees is often used as pasture.
Uses
The species is widely cultivated for its edible seeds (also called nuts) and for its wood.

The first charcoal remains of sweet chestnut only d…
