Dates Palm

Dates Palm, is a type of flowering plant in the palm family, Arecaceae, cultivated for edible sweet fruit. Dates have been staples in the Middle East and the Indus Valley for thousands of years. There is archaeological evidence of dates planting in the Arabian Peninsula since the 6th millennium BC.

Date trees reach about 21 to 23 meters in height, grow individually or form a mass with several trunks of a single root system. Dates are Oval-cylindrical, 3–7 cm (1.2–2.8) in long, and about an inch (2.5 cm) in diameter, ranging in colors from red to light yellow. They are very sweet, containing about 75 percent of sugar when dried.

P. dactylifera is the type species of genus Phoenix, which contains 12–19 species of wild date palms, and is the major source of commercial production. The total annual global production of dates is 8.5 million metric tons. The countries of the Middle East and North Africa are the largest producers.

Cultivation of Dates Palm

Dates are important crops in the Arabian Peninsula, Iraq, and North Africa. Dates such as Medjool and Deglet Noor are grown in Southern California, Arizona, South Florida in the United States and in Sonora and Baja California in Mexico.

Palm trees take 4 to 8 years after cultivation before they bear fruit, and begin to produce viable yields for harvesting between 7 and 10 years. Mature palm trees produce between (70-140 kg) of dates in the harvest season. Date fruit does not mature at the same time, so many crops are required. To obtain the high-quality fruit, date bunches should be thinned and covered before maturity so that the remaining fruits are larger and protected from weather and pests.

Palm trees need deep sandy loam soils that are well depleted with an acidity of 8-11. Soil must have the ability to retain moisture. Calcium should not exceed 25% in the soil. Because increasing it leads to poor productivity of palm trees.

The Growth Stages of Date

Dates take about 7 months from the time they leave the casing until they are fully mature. Dates need very hot and dry weather and plenty of water at their roots.

  1. In hababuk stage, the pollination is done by hand. In nature, half of the palm is male, but in agriculture, females are mostly planted. One male is grown for 50 females. Pollen flowers are cut from the male tree and the pollen is extracted, and then applied by hand to the female flowers to ensure a good fruit group.
  2. Kimri is the second stage of the growth of date fruit and the fruit begins to elongate and becomes green and characterized by a rapid increase in weight and size. In the late kimri or early Khalaal, bunches of fruit are bagged; this keeps the dates from rain, birds and sun burning. This is done by a paper wrap or nylon bag.
  3. The khalal stage, the date fruit is characterized by weight gain and the color changes to yellow, red or blond and this takes about 3 to 5 weeks.
  4. In the rutab (wet) phase, the fruit becomes watery and sweet and ranging from 2-4 weeks.
  5. If allowed to hang on the trees for two or three weeks, they will be tamr. At this stage, the fruits of the dates are smooth and contain moisture content less than wet. Most dates are harvested at the tamr stage. There are more than 450 species of tamr dates in the world.

Culture

Dates are mentioned 20 times in the Quran and more than 50 times in the Bible.

In the Holy Quran, the God guides Virgin Mariam (Mary) to eat dates at the birth of Isa (Jesus) according to the verses 23, 24, 25, 26 from Surah Mariam (Mary).

The English translation of these verses, as in the English Translation of The Noble Quran - NobleQuran.com, is: “In the Name of Allah, the Most Gracious, and the Most Merciful.

23. And the pains of childbirth drove her to the trunk of a date-palm. She said: "Would that I had died before this, and had been forgotten and out of sight!"

24. Then [the babe 'Iesa (Jesus) or Jibrael (Gabriel)] cried unto her from below her, saying: "Grieve not! Your Lord has provided a water stream under you;

25. "And shake the trunk of date-palm towards you; it will let fall fresh ripe dates upon you."

26. "So eat and drink and be glad, and if you see any human being, say: 'Verily! I have vowed a fast unto the Most Beneficent (Allah) so I shall not speak to any human being this day.'" (Surah 19: Maryam).

Also, in the Islamic culture, during fasting the month of Ramadan, dates, milk or water are the first foods consumed for Iftar (fasting break) after sunset. This helps not to over-eat after the end of the day of fasting because when the body begins to absorb the high nutritional value of dates, the feeling of hunger recedes.

      I love dates. We used to have them at Christmas. I was known for sneaking into the kitchen as a child to eat them.

      Your research is superb! I've learned a great deal more about this fruit. I lived in the Coachella Valley of California and they have a number of date farms in the area. They grow Medjool and Deglet Noor varieties. I visited a date farm museum to learn about the cultivation, harvesting and history. The souvenir shop serves date milk shakes which are very tasty. I don't eat dates very often because of the high sugar and calorie content but I do like them!
