INTERCROPPING
To
make the best use of the farm, it was and still a common practice to
grow cotton, maize, alfalfa, wheat, vegetables, and fruits between and
under the palm trees. Ward reported that grapevines, peaches, sweet
lime, plums, apricot, and pomegranate were grown with the date palm
at Wadi Tayin, Wadi Benikhalid and Wadi Halfain in Sharqya region. Most
commonly in the level land is to interplant palms with citrus and alfalfa.
According to the FAO paper, conditions in the old world often favor
interplanting. First, The sensitivity of some fruit crops like citrus
to harsh conditions, such as the high temperature, extremely cold or
hot dry winds, and the strong sun make the date palm plantation shade
the best way of producing high value fruit trees. Second, Interplanted
is favored by small poor farmers who own an inherited a small date garden,
thus planting some other fruit trees would provide an alternative income
source. In addition, growing some of the fruit or fodder crop to be
consumed by the household or provide income throughout the year is another
perspective of practicing interplanting in old palm orchards especially
at early years of orchard establishment when the return from it is low.
These inter-crops also improve nutrition status and the physical properties
of the soil.
POLLINATION
AND BUNCH HANGING
The traditional pollination of female trees as described by Elmardi
is achieved by inserting three or more dry male strands inside each
female spadix just as it starts open. After that, the spadix is tied
with a stripe of a date leaf to keep the strands in place in a way that
ensure expansion of the fruits. The strands are laid upside-down or
horizontally within the female flowers. The pollination is repeated
as long as the female spadix opens. During this operation, the thorns
are removed to facilitate bunch hanging and harvesting later on. Pollination
is normally carried out after sunrise and before sunset, when conditions
such as calm wind, warm temperature and no precipitation conditions
are favorable for pollination. Pollination require knowledge and high
skills in order to be carried out properly. The two major male cultivars
that are used for pollination are Khori and Bahlani. Ibn al-Awwam says
in pollination " I fecundated a wild palm in al-Sharaf at the time
of opening of the flowers, with those of a male introduced in and tied
in, and dates of good quality were produced; which operation is done
only once a year, but it is necessary to repeat it each year as for
figs". Several operations are performed after pollination and fruit
set. This include thinning of heavily loaded palms, release of bunches
from the tree crown, thinning the bunches and protection from birds
and rodents. Bunch Hanging comes after the date fruits have developed
before the ripening. According to Elmardi , three weeks after pollination
the bunches are pulled under the lower leaves and tied to the leaf rachis
with a rope or palm leaflets. The main purpose of bunch hanging is to
keep the dates from being scratched or bruised by thorns or leaflets
during windy conditions, reduce fruit dropping and facilitate harvesting.
PRUNING
This
is considered by all farmers the most important operation that is conducted
regularly to the date palm. Pruning is practiced by removal of old dead
or broken leaves . The leaves are used as by-product for making crates,
ropes and baskets, they also considered a good source of fuel for heating
and cooking and even house construction. Using two types of tools used
for pruning, Sickle which is a saw-toothed curved blade used to cut
leaf bases, and Slanting curved cutting blade with a slight out curve
and attached to a wooden handle, most of these tools are made locally.
The purpose of pruning is to clean out the tree, allow new leaves to
grow and photosynthesize, reduce rodent and insect infestation, facilitate
harvesting, use of leaves as by-product material and make use of the
fiber on the leaf base, and improving crop quality by reducing shade
and bruising of fruits. When the palm is pruned, the offshoot and the
rekab which is the sucker on the crown of the tree are also pruned.
