Pistachios are small trees or shrubs, and their fruits are called pistachio nuts. Pistachio nuts have been used as food for over 2,5 years. They were especially revered in Persia – as a symbol of wealth. Pistachio nuts have a high nutritional value – they contain more than 50% fat, as well as a lot of proteins and carbohydrates. They have a tonic effect, and they are recommended for chronic fatigue.

Pistachios are cultivated in the Mediterranean, Northwest Africa, West, Central and East Asia. Two types of pistachios are found in Central America, as well as in the south of Texas (USA).

Pistachios bloom in March-May, bear fruit in July-September. After harvesting, the nuts are dried in the sun. After that, they can be stored for no more than a year. They are also soaked in saline and fried.

The most prominent representative of the Pistachio genus is the Pistachio real or Pistachio tree. The real pistachio is of great commercial value, since its fruits are several times larger than those of other species of this genus. Under natural conditions, this species is found on the slopes of the mountains of Central Asia (Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan), in the north-east of Iran, in Syria and in the north of Afghanistan. In similar climatic conditions, real pistachio is bred and successfully cultivated in many parts of the world.

Pistachios grow in areas with a continental climate, which is characterized by long hot summers, when the air temperature often rises above 40 °C, and the humidity drops to 10%. At the same time, the soil surface heats up above 70 °C, and there is no moisture available to plants at all. That is why the plants have a huge two-tiered root system – the roots go to the sides by 30-40 meters, to a depth of 12-15 meters.

Everywhere pistachios grow in single specimens, but sometimes they form sparse pistachio forests.

Pistachio is photophilous, heat- and frost-resistant, it easily tolerates frosts down to −30 °C.

The pistachio tree begins to bear fruit from the age of seven or eight, abundant fruiting begins at the age of 15 and increases up to 100 years. Each tree bears fruit with a one-year break, especially fruitful years are repeated after 3-5 years. From one tree, you can collect 12-15 kg of fruit. In culture, it was possible to obtain up to 250 kg of fruits from one tree.

World production of pistachio nuts is actively growing from year to year and amounts to more than 1 million tons. Let's name the 10 largest producers of pistachio nuts (in descending order, starting from the largest): Iran, Turkey, USA, China, Syria, Greece, Spain, Italy, Tunisia, Afghanistan.
