It is believed that Prophet Muhammad used to break his fast with dates. Muslims follow the tradition of breaking Ramadan fast with dates fruit, which is also an instant energy source.

Dates are fruits of the date palm (Phoenix dactylifera), which is believed to have originated from areas surrounding the Persian Gulf. The present day Iraq is considered the birthplace of this tree, which is now widely cultivated in many parts of the world. According to fossil records, this palm tree existed on the Earth before 50 million years.

Date palm is one of the oldest fruit crops and the history of date fruit cultivation can be traced back to the period of Ancient Egyptians. Even the Arabs started cultivating date palm from 6000 BCE. Archeological evidence indicates that the people of Indus Valley used to cultivate date palms and consume the fruits. It was the Arabs, who introduced this fruit to other parts of the world. Now, there are numerous date palm cultivars that produce delicious and nutritious fruits that are consumed by people across the globe.
Date Palm - Phoenix dactylifera
The date palm belongs to the genus Phoenix. Usually, this palm tree grows in semi-arid regions with high levels of groundwater. The date palm grows to a height of 25 to 30 meters, and has a crown with a diameter of six to ten meters. The pinnate leaves of the palm has long, thin leaflets. The petiole has spines and each leaflet can be around 12 inches long and two inches wide. Fruits are formed in clusters, that develop from the axils of leaves. While date palms require high groundwater levels, they also need extremely hot weather for bearing fruits.

On an average, this palm takes four to eight years to bear fruit. In case of date palms, male and female trees are separate. Wind plays a major role, as far as natural pollination is concerned. In case of commercial cultivation, machines are used for pollinating date trees. Traditional farmers go for hand pollination, wherein the male flowers are harvested to collect the pollen, which is smeared over the female flowers. A single male tree is sufficient to pollinate around 50 female date palms. The fruit bunches are thinned to provide adequate ventilation that is required for proper growth. Rings are also inserted into the fruit clusters, for this purpose. Ripe fruits are covered to protect them from birds and other pests.

Dates Fruit - Stages of Development
Dates fruit can be classified according to the degree of ripeness. The development of date fruits is divided into four stages. The first stage is termed hababouk, when the fruits are in the premature stage, right after pollination. During this stage, dates are small and creamy. Date fruits, which are in the second to seventeenth week of growth are called kimri. As they pass through this second stage, the fruits remain green and hard. They have a high moisture content and some amount of sugars. However, these dates are bitter.

The next six weeks comprise the khalal stage, when the fruits attain their full size. Their color changes to yellow, orange or red, but they remain hard and unripe. The sugar content increases during this stage. The rutab stage denotes the next four weeks of growth. During this period, the fruits turn brownish at the tips. They soften a little, and lose some moisture and weight.

When the fruits are allowed to ripe further, they turn semi-dry or dry and wrinkled. These last two weeks denote the tamr stage. While some varieties of dates are harvested during the khalal stage, the rutab stage is ideal for others. Let us take a look at the different cultivars of date palm.

Date cultivars are classified into three categories - soft, semi dry, and dry. While 'medjool' and 'Barhee' are among the popular varieties of soft dates; 'Dayri' and 'Deglet Noor' are classified as semi dry; and 'thoory' is a major dry type of date fruits. While soft dates are harvested before they turn soft, semi-dry ones are picked as soon as they turn soft. The dry ones are not harvested, till they get fully ripe on the palm trees.

Dates can be eaten as such or can be pitted and filled. Walnuts, cashews, almonds, candied orange, marzipan, cream cheese, and tahini, are some of the common fillings. Dates are among the most indispensable ingredients in both Middle Eastern and Mediterranean cuisines.
