Phoenix dactylifera (Sanskrit:Kharjūra खर्जूर, Hindi:खजूर), commonly known as the Date Palm, is a palm in the genus Phoenix, extensively cultivated for its edible sweet fruit. Due to its long history of cultivation for fruit, its exact native distribution is unknown, but probably originated somewhere in the desert oases of northern Africa, and perhaps also southwest Asia. It is a medium-sized tree, 15–25 m tall, often clumped with several trunks from a single root system, but often growing singly as well. The leaves are pinnate, 3–5 m long, with spines on the petiole and about 150 leaflets; the leaflets are 30 cm long and 2 cm broad. The full span of the crown ranges from 6 to 10 meters.

Iraq

is the largest producer in the world in spite of the huge damage to the date industry that happened in the 1980s and 1990s.

History of dates

Dates have been a staple food of the Middle East for thousands of years. They are believed to have originated around the Persian Gulf

, and have been cultivated since ancient times from Mesopotamia to prehistoric Egypt

, possibly as early as 4000 BCE. There is archaeological evidence of date cultivation in eastern Arabia in 6000 BCE. (Alvarez-Mon 2006).

In later times, Arabs spread dates around South and South West Asia, northern Africa, and Spain

and Italy

. Dates were introduced into Mexico

and California

by the Spaniards by 1765, around Mission San Ignacio.

Dates

The fruit is a drupe known as a date. Dates are oval-cylindrical, 3–7 cm long, and 2–3 cm diameter, and when unripe, range from bright red to bright yellow in colour, depending on variety. Dates contain a single seed about 2–2.5 cm long and 6–8 mm thick. Three main cultivar groups of date exist: soft (e.g. 'Barhee', 'Halawy', 'Khadrawy', 'Medjool'), semi-dry (e.g. 'Dayri', 'Deglet Noor', 'Zahidi'), and dry (e.g. 'Thoory'). The type of fruit depends on the glucose, fructose and sucrose content.

The Date Palm is dioecious, having separate male and female plants. They can be easily grown from seed, but only 50% of seedlings will be female and hence fruit bearing, and dates from seedling plants are often smaller and of poorer quality. Most commercial plantations thus use cuttings of heavily cropping cultivars, mainly 'Medjool' as this cultivar produces particularly high yields of large, sweet fruit. Plants grown from cuttings will fruit 2–3 years earlier than seedling plants.

Dates are naturally wind pollinated but in both traditional oasis horticulture and in the modern commercial orchards they are entirely pollinated manually. Natural pollination occurs with about an equal number of male and female plants. However, with assistance, one male can pollenate up to 100 females. Since the males are of value only as pollenators, this allows the growers to use their resources for many more fruit producing female plants. Some growers do not even maintain any male plants as male flowers become available at local markets at pollination time. Manual pollination is done by skilled labourers on ladders, or in some areas such as Iraq

they climb the tree using a special climbing tool that wraps around the tree trunk and the climber's back to keep him attached to the trunk while climbing. Less often the pollen may be blown onto the female flowers by a wind machine.

Parthenocarpic cultivars are available but the seedless fruit is smaller and of lower quality.

Dates ripen in four stages, which are known throughout the world by their Arabic names kimri (unripe), khalal (full-size, crunchy), rutab (ripe, soft), tamr (ripe, sun-dried). A 100 gram portion of fresh dates is a source of vitamin C and supplies 230 kcal (960 kJ) of energy. Since dates contain relatively little water, they do not become much more concentrated upon drying, although the vitamin C is lost in the process.

Dates are an important traditional crop in Turkey

, Iraq

, Arabia, and north Africa west to Morocco

and are mentioned in many places in the Quran. In Islamic countries, dates and yogurt or milk are a traditional first meal when the sun sets during Ramadan. Dates (especially Medjool and Deglet Noor) are also cultivated in southern California

, Arizona

and southern Florida

in the United States

.

Date palms can take 4 to 7 years after planting before they will bear fruit, and produce viable yields for commercial harvest between 7 to 10 years. Mature date palms can produce 80–120 kilograms (176–264 lbs) of dates per harvest season, although they do not all ripen at the same time so several harvests are required. In order to get fruit of marketable quality, the bunches of dates must be thinned and bagged or covered before ripening so that the remaining fruits grow larger and are protected from weather & pests such as birds.

Cultivars of dates

A large number of date cultivars are grown. The most important are:

Aabel — common in Libya
Ajwah — from the town of ‘Ajwah in Saudi Arabia, it is the subject of a famous hadith of the Prophet Muhammad.
Al-Barakah — from Saudi Arabia
Amir Hajj or 'Amer Hajj' — from Iraq, these are soft with a thin skin and thick flesh, sometimes called "the visitor's date" because it is a delicacy served to guests.

Barhee or (barhi) (from Arabic barh, a hot wind) — these are nearly cylindrical, light amber to dark brown when ripe; soft, with thick flesh and rich flavour. One of the few varieties that are good in the khalal stage when they are yellow (like a fresh grape as opposed to dry, like a raisin).
Bireir (Arabic: برير‎) — from Sudan
Deglet Noor (Arabic: 'translucent' or 'date of light') — so named because the centre appears light or golden when held up to the sun. This is a leading date in Algeria , the USA , and Tunisia , and in the latter country it is grown in inland oases and is the chief export cultivar. It is semi-dry and not very sweet.
Derrie or 'Dayri' (the 'Monastery' date) — from southern Iraq — these are long, slender, nearly black, and soft.

Mishriq (Arabic: 'East' — مشرق)‎ — from Sudan and Saudi Arabia
Mozafati — from Iran, where it is mainly grown in Kerman province, and often named "Bam (Mozafati) dates", after a city in that province. It is a dark, soft and sweet date of medium size. It is exceptionally well-suited for fresh consumption, because of its long shelf life. At a temperature of -5 celcius it can be kept for up to 2 years. It accounts for 10% of total Iranian date crop. (100.000 tons, of which 30% is exported)

Umeljwary — in Libya.
Umelkhashab — Brilliant red skin; bittersweet, hard white flesh (Saudi Arabia).
Zahidi (Arabic: '[Of the] ascetic') — these medium size, cylindrical, light golden-brown semi-dry dates are very sugary, and sold as soft, medium-hard and hard.

There are more than 100 known cultivars in Iraq

. It should be noted, however, that a cultivar can have several names depending on the locality.

Iraq

has long been a major producer of dates. While the amount of dates produced and exported has decreased in recent years, it is still the world's major producer of dates with 87% of the world's exports.

Food uses

Dry or soft dates are eaten out-of-hand, or may be pitted and stuffed with fillings such as almonds, walnuts, candied orange and lemon peel, tahini, marzipan or cream cheese. Pitted dates are also referred to as stoned dates. Dates can also be chopped and used in a range of sweet and savory dishes, from tajines (tagines) in Morocco

to puddings, ka'ak (types of Arab cookies) and other dessert items. Dates are also processed into cubes, paste called "'ajwa", spread, date syrup or "honey" called "dibs" or "rub" in Libya, powder (date sugar), vinegar or alcohol. Recent innovations include chocolate-covered dates and products such as sparkling date juice, used in some Islamic countries as a non-alcoholic version of champagne, for special occasions and religious times such as Ramadan.

Dates can also be dehydrated, ground and mixed with grain to form a nutritious stockfeed. Dried dates are fed to camels, horses and dogs in the Sahara. In northern Nigeria

, dates and pepper added to the native beer are believed to make it less intoxicating.

Young date leaves are cooked and eaten as a vegetable, as is the terminal bud or heart, though its removal kills the palm. The finely ground seeds are mixed with flour to make bread in times of scarcity. The flowers of the date palm are also edible. Traditionally the female flowers are the most available for sale and weigh 300–400 grams. The flower buds are used in salad or ground with dried fish to make a condiment for bread.

According to a study by Al-Shahib and Marshall, in many ways, "dates may be considered as an almost ideal food, providing a wide range of essential nutrients and potential health benefits." The sugar content of ripe dates is about 80%; the remainder consists of protein, fat and mineral products including copper, sulfur, iron, magnesium and fluoric acid. Dates are high in fiber and an excellent source of potassium.

In India

and Pakistan

, North Africa, Ghana

, and Côte d'Ivoire

, date palms are tapped for the sweet sap, which is converted into palm sugar (known as jaggery or gur), molasses or alcoholic beverages. In North Africa the sap obtained from tapping palm trees is known as lāgbī ( ). If left for a sufficient period of time (typically hours, depending on the temperature) lāgbī easily becomes an alcoholic drink. Special skill is required when tapping the palm tree so that it does not die.

In Southeast Spain (where a large date plantation exists including UNESCO

protected Palmeral of Elche

) dates (usually pitted with fried almond) are served wrapped in bacon and shallow fried.

It is also used to make Jallab.

Other uses of the plant

Date seeds are soaked and ground up for animal feed. Their oil is suitable for use in soap and cosmetics. They can also be processed chemically as a source of oxalic acid. The seeds are also burned to make charcoal for silversmiths, and can be strung in necklaces. Date seeds are also ground and used in the manner of coffee beans, or as an additive to coffee.

Stripped fruit clusters are used as brooms. In Pakistan, a viscous, thick syrup made from the ripe fruits is used as a coating for leather bags and pipes to prevent leaking.

Date palm sap is used to make palm syrup and numerous edible products derived from the syrup.

Date palm leaves are used for Palm Sunday in the Christian religion. In North Africa, they are commonly used for making huts. Mature leaves are also made into mats, screens, baskets and fans. Processed leaves can be used for insulating board. Dried leaf petiole are a source of cellulose pulp, used for walking sticks, brooms, fishing floats and fuel. Leaf sheaths are prized for their scent, and fibre from them is also used for rope, coarse cloth, and large hats. The leaves are also used as a lulav in the Jewish holiday of Sukkot.

Date palm wood is used for posts and rafters for huts; it is lighter than coconut and not very durable. It is also used for construction such as bridges and aqueducts, and parts of dhows. Leftover wood is burnt for fuel.

Where craft traditions still thrive, such as in Oman

, the palm tree is the most versatile of all indigenous plants, and virtually every part of the tree is utilized to make functional items ranging from rope and baskets to beehives, fishing boats, and traditional dwellings.

Traditional medicinal uses

Dates have a high tannin content and are used medicinally as a detersive (having cleansing power) and astringent in intestinal troubles. As an infusion, decoction, syrup, or paste, dates may be administered for sore throat, colds, bronchial catarrh, and taken to relieve fever and number of other complaints. One traditional belief is that it can counteract alcohol intoxication. The seed powder is also used in some traditional medicines.

A gum that exudes from the wounded trunk is employed in India for treating diarrhea and genito-urinary ailments. The roots are used against toothache. The pollen yields an estrogenic principle, estrone, and has a gonadotropic effect on young rats.

Diseases

Date Palms are susceptible to a disease called Bayoud disease, which is caused by the fungus Fusarium oxysporum. This disease, which kills many of the popular older cultivars like 'Deglet Noor', has led to a major decline in production where it is present, notably Morocco

and western Algeria

. However, new cultivars resistant to the disease are being developed.
