HISTORY
Date palm is one of the oldest plants cultivated by man and its origin
is thought to be Mesopotamia (Iraq), Gulf region or Indus Civilization.
The presence of date fruits in the excavation of Moen-jo-Daro storage
vases indicates the presence of date palm cultivation in Sindh as early
as 2000 B.C (Jandan, 1974). Whereas, silicified seeds or mineralized
date stones of 6000 B.C have been tested from Mehargarh IB and IIB
sites of Pakistan (Costantini, 1985). On the other hand some scholars
believed that date palm have been brought to the Indo-Pak subcontinent
by Alexander the great (Pasha et al., 1972 and Nixon, 1951). While it is a
general concept among scholars that dates were probably introduced in
Sindh by Forces of Mohammed Bin Qasim in 712 A.D. Because, since
the dawn of ancient history, the Date Palm has been an important source
of food for the Arabian Peninsula (Popenoe, 1913). They threw date
seeds at camping places during wars from which date palm grew and
flourished in the Indus valley.
GENERAL DESCRIPTION
Date palm belongs to family Arecaceae, is a monocot, perennial
plant extensively cultivated for its edible sweet fruit. The fruit is a drupe
known as a date. The term Phoenix dactylifera L. was given by Carolus
Linnaeus in his binomial nomenclature in 1753. The term Dactylifera is
derived from the Greek word “Dactylor” which means “finger”. Date palm
being a dioecious plant is conventionally propagated through its
offshoots because propagation through its seeds will not bring the true to
type progeny of Date Palm. However Plant tissue culture is a new and
fast growing method for propagation of date palm and is practicing in
many date palm growing regions, including Sindh, where a well
established institute namely “Date Palm Research Institute, Khairpur” is
working on various aspects of date palm including its propagation
through plant tissue culture.

Date Palm likes a warm climate where summers are considerably
longer than winters. As per an Arabic saying the date palm should be
grown with its feet in running water and its head in fire. Date Palm
prefers a rainfall of 200 to 250 mm; late rains during flowering and
ripening periods are harmful for date palm. Date palm requires sandy
loam and clayey loam soils and can tolerate soils with high levels of salts
up to 22,000 parts per million (Gepts, 2002).
Date Palm may reach an age of 100-150 years and height of 100-
120 feet or 30 m (Gepts, 2002). Normally the useful age limit is less and
consequently the height will not be more than 15-20 m maximum before
it will cut down because of declining yield and increasing difficulty and
danger to reach the crown during pollination, bunch management and
harvesting. Dates are naturally wind pollinated in both traditional oasis
and horticulture but 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, male
flowers from a single tree can be used to pollinate 40 to 50 female date
palms (Rani et al., 2007).The main stages in the date palm life cycle are:
• Suitable age of suckers for transplanting 2-3 years
• Time to start bearing fruits 4-5 years
• Time to full production 6-8 years
• Full productivity but no more offshoots formation 30-35 years
• Normal economic bearing life 50 years
• Declining fruit yields after 50 years
• Time of transplanting Whole year, specially May to July
• Time of flowering Feb to March
• Time of harvest July to Oct
The dates in one growing season take 200-210 days from pollination
to full fruit maturation (Saleem, 2004). According to Al-Hooti et al., (1997)
fruit maturation undergoes through four major stages, identified by their
Arabic names as:
1. Kimri: Small green, hard texture, non edible with high moisture
approximately 80%.
Proceedings of the International Dates Seminar 28th July 2009, Khairpur, Sindh, Pakistan
62
2. Khalal (Doka stage): Bright yellow or red in color, hard and crisp,
physiologically mature, moisture contents 50-85%.
3. Rutab (Dang stage): Partially browned and softened at the tip and
reduced moisture contents to 30-35%.
4. Tamar (Pind or Chuhhara stage): Color from Amber to dark brown,
texture from soft pliable to firm, moisture content reduced below 25%
down to 10% and less.
IMPORTANCE
Date fruits being sweet and most nutritious supplying 2500-3000
Calories/kg (Amin, 2007) consumed as a staple food because the sugar
content of ripe dates is about 80%; the remainder consists of protein, fat
and mineral products including copper, sulphur, iron, magnesium and
fluoric acid. Dates are high in fiber and an excellent source of potassium.
Date palm with its unique characteristics can truly be called the “tree
of life “ because date palm has been so closely connected with the
survival and well being of humans living in hot and arid environments.
Without the existence of the date palm, expansion of human race into the
hot and barren part of the ancient world would have been much more
restricted.
Every part of the date palm tree has its uses. The wood and leaves
provide timber and fabric for houses and fences. The leaves are used for
making ropes, fans, mats, hats, cord, baskets, crates and furniture.
Bases of the leaves and the fruit stalks are used as fuel. The fruit yields
food products such as date vinegar, date chutney or sweet pickle, date
paste for bakery products etc.
The Date palm has religious values as well as cultural importance in
all major religions of the world. It is important in ceremonies of Judaism,
Christianity, Islam and Hinduism. The reason for this is mainly the
influence of Prophet Ibrahim, whose love for dates and date palm has left
a lasting influence on these religions. According to the Holy Book Qur'an,
dates have always been considered beneficial to mothers. When Mary
gave birth to the Prophet Jesus (may peace be upon Him) under a palm
tree, she heard a voice telling her: "Shake the trunk of the palm tree
towards thee: it will drop fresh, ripe dates upon thee. Eat, then, and

drink, and let thine eye be gladdened!" (Qur'an 19:25-26). There are over
20 references to date and date palms in the Holy Quran. The Holy
Prophet (Peace be Upon Him) also highlighted the importance of dates
and date palms on many occasions. Such as: There is among trees one
that is pre-eminently blessed, as is the Muslim among men; it is the date
palm" and “Homes without dates is as good as a home without food”.
DATE PALM DISEASES
Diseases in date palm may be either biotic or abiotic. Biotic diseases
are caused by pathogens like fungi and bacteria and insects like Red
Palm Weevil and Fruit stalk borer etc. Both pathogens and insects are
responsible for great damage to date palm in Sindh. Abiotic diseases are
caused by Physiological disorders such as, too low or too high
temperature, lack or excess of soil moisture, lack or excess of light, lack
of oxygen, air pollution, nutrient deficiencies, toxicities of pesticides etc.
Some palms show resistance to their biotic pathogens and to conditions
which cause abiotic diseases but all date palms are susceptible to
mismanagement of water, the extremes of pruning and poor planting
practices.
BIOTIC DISEASES
Biotic diseases are caused by pathogens and are usually fungal in
etiology, the most common fungal diseases of Date Palm in Sindh are:
• Sudden decline of date palm (drying) in Sindh caused by soil borne fungi Fusarium spp.
• Grapholia leaf spot caused by Grapholia phoenicis.
• Leaf spot of Date Palm caused by Mycosphaerella spp.
• Inflorescence rot of Date Palm caused by Mauginiella scaettae.
• Fruit rot of Date Palm caused by Aspergilus spp.
• Diplodia disease of date palm caused by Diplodia phoenicum.
While the Red Palm Weevil or Indian Palm Weevil, Rhynchophorus
ferrugineus is also damaging the date crop in Sindh. It bores into the
stem from the exposed soft tissues and entire crown to wither and die
Whereas Lesser Date Moth (Batrachedra amydraula Meyrick) and Fruit
Stalk Borer (Oryctes elegans Prell) are also causing a great damage to
date palm.

ABIOTIC DISEASES
Abiotic diseases are caused by re-occurring environmental
conditions that compromise the long-term growth and development of the
palm. Some of them described by Zaid et al., (2002) are given below:
Crosscuts
A crosscut is a physiological disorder of fruit stalks and fronds.
Crosscuts or V-cuts are clean breaks in the tissues of the fruit stalk
bases and on fronds. It consists of a slight to deep notch, similar to a cut
artificially done by a knife. Fruits born on strands in line with the break
wither and fail to mature properly. Crosscuts result from an anatomical
defect in the fruit stalks and fronds involving internal, sterile cavities
leading to mechanical breaks during elongation of the stalk or the fronds.
Leaf Apical Drying
This is not a disease but a physiological reaction to transplantation of
adult palms (injury of their root system). All palms with these symptoms
recover within two to three years after their transplanting.
Frost Damage
When temperature falls below 0°C, it causes serious metabolic
disorders with some injury to date palm leaves characterized by a partial
or total desiccation. Water of protoplasma freezes after coming out from
the cells. During defrost, water invaded inter-cellular spaces and affected
leaves turn brown and desiccated. The severity of damage is related to
the intensity and duration of frost. Frost injury to the date palm groves is
not a direct loss of fruit on the palm but freezing produces loss of leaves
so that the palm cannot support and mature the fruit crop following year.
DATE PALM VARIETIES
Date varieties have been developed by thousands of years of
selection of seedlings and only those possessing desirable
characteristics have been propagated. Date palm counts for more than
3000 varieties all around the world. There are about 400 in Iran, 370 in
Iraq, 250 in Tunisia, 244 in Morocco, as well as many additional varieties
in the other major date growing countries (Rani et al., 2007). Whereas
Popenoe listed 1,500 descriptions of the fruit and palm, as well as the
history and significance of the most important, country by country, in his
book, The Date Palm (written in 1924 but published in 1973).

There are three main cultivar groups of dates e.g. soft, semi-dry and
dry. The type of fruit depends on the glucose, fructose and sucrose
content. In soft dates about 80 percent of the dry matter is invert sugars
(mixture of equal parts of glucose and fructose), while in semi-dry dates,
about 40 percent of the dry matter is invert sugars and forty percent is
sucrose. In dry dates, about 20 to 40 percent of the dry matter is invert
sugars and 40 to 60 percent is sucrose (Bender and Bender, 2005).
There are more than 300 varieties of dates in Khairpur, Sindh,
Pakistan and this is the biodiversity centre of dates (Markhand and Abul
Soad, 2007 and Mahar, 2007). Province wise Elite date varieties of
Pakistan are:
Sindh: Aseel, Karbalian, Fasli, Dedhi, Kupro, Gajjar, Kachoo wari,
Began, Mithri, Bhedir, Khar, Autaqin and Asul khurmo.
Punjab: Zahidi, Hilawi, Khudravi and Shamran.
Baluchistan: Muzawati, Begum Jangi, Shakri, Halini, Sabzo, Hussaini,
Aab-e-dandan, Jaan Swore, Kehraba and Rabai.
NWFP: Dhakki and Gulistan.
ASEEL VARIETY
The Aseel variety is the most important commercial variety of
Pakistan. This is a predominant variety of Khairpur. It is an excellent
semi-dry variety with suitable fruit size (4.3 cm in length and 2.5 cm in
diameter), oblong, narrow near the base and widest in the middle. The
fruit of this variety is consumed at Rutab (Dang) and Tamr stage. Aseel
has sweet taste without scorch in the throat. This is very important
character for the excellent varieties. The environmental conditions and
soil types play an important role in the properties of this variety's fruit.
Aseel fruit produced from palms grown in Eastern part of district (near to
small mountain range) has low moisture content. Consequently, the shelf
life of this fruit is longer than the fruit of the same variety in the rest of
district. The fruit of Aseel variety cannot be eaten at Khalal stage due to
the high percentage of tannins. However, many growers harvest Aseel
crop at khalal stage and boil fruit to make "Chuhara". Otherwise, whole of
the crop will be destroyed and lost if there is monsoon rain (Markhand
and Abul Soad, 2007).

DATES PRODUCTION
Dates are cultivated mainly in warmer regions of Asia and Africa.
Some important date growing countries are Iran, Egypt, Saudi Arabia,
Pakistan, Algeria, Sudan, Libya, and Tunisia. It is also grown in some
parts of Europe (Italy, Spain) and California (USA).
Due to soil and seasons, Pakistan is an ideal place for date palm
cultivation. The area under cultivation of date palm is 90100 hectares
with production of 600000 tons of dates annually and is fourth largest
producer of dates in the world after Egypt, Iran and Saudi Arabia.
As per figures of Federal Bureau of Statistics of Pakistan (2007-08),
year wise area and production of Dates of Pakistan is given in “000”
thousands of hectares and production in tons.

Dates are growing in all four provinces of Pakistan. The main dates
producing areas of Pakistan are Turbat and Panjgoor (Baluchistan),
Khairpur and Sukkur (Sindh), Muzaffar Garh, Jhang, Multan and D.G
Khan (Punjab) and D.I. Khan (NWFP).
It is evident from the area that the trend of date palm cultivation is
increasing. Comparison of production and area of dates in Pakistan and
Sindh and its share is given below:

Date Palm is an important crop of Sindh, mainly growing in Khairpur
and Sukkur districts. Almost 85% of the Sindh dates produced only in
Khairpur.
DATES IMPORT
Pakistan imports dates worth around $4.45 million annually. This
import is made in spite of domestic production of over 600000 tons a
year. When Ramazan will precede dates harvesting season, import of
this fruit will increase manifold (Jalbani, 2009).
According to FAOSTAT (2007) the major importers of dates are:

DATES EXPORT
Date palm is the third commercial fruit crop of Pakistan after Citrus
and Mango (Pakistan Horticulture Development and Export Board). The
export of dates is mainly occurring from Khairpur and Turbat districts of
Pakistan. Pakistan appeared on the map of date exporting countries of
the world in the beginning of 1980s when Iran and Iraq went to war and
now became the second largest exporter of this fruit in the world
(FAOSTAT, 2007).
According to FAOSTAT (2007) world Dates export is as under:

The date markets of Khairpur and Sukkur export about 80-90% of
dried dates (Chuhara) to India, where being used in religious activities.
But the tension between India and Pakistan after Mumbai blast has
affected export of dried dates to India. Thus we are supposed to find out
new markets for our dates or it will be a great loss.
RECOMMENDATIONS
Pakistan has vast potential of export dates but efforts are required to
apply post-harvest management and processing techniques to qualify
the International standards. For better production and yield of dates there
is a need of extensive research so that quality could match with
international requirements of sanitary and phyto-sanitary (SPS)
measures; selection of disease-free plants; screening out of bad
varieties, pre and post-harvest management; processing and behavioral
trainings of the staff for their role in the system; integrated supply chain
(from farm to fork) for handling, processing, packing, marketing and
export of dates and date products. Other measures include setting up of
advanced dates processing and preservation units in date growing
areas, standardized packaging and presentation, national branding and
market diversification and establishment of modern marketing system.
