Agriculture
is the
basic industry of Jamaica. As the island possesses
a wide variety of soil and climate, nearly every
tropical product can be grown here. The chief
economic crops are sugar, bananas, citrus, cocoa
and coconuts, each of which is dealt with below
in detail. Not one of the major crops of the
island is indigenous. Sugar cane, coconut, rice
and ginger were introduced into the island from
Far Eastern countries, bananas from the Canary
Islands, cocoa from South America, limes and
mangoes from India, the breadfruit from Tahiti
and ackee from Africa.
Pimento
Pimento is grown largely in St. Ann, Trelawny,
Manchester and St. Elizabeth. Ginger grows well
in Jamaica, especially at elevations of over
2,000 feet above sea level. Logwood, from which
a dye is extracted, is found on the dry plains
of St. Catherine, Clarendon and St. Elizabeth.
Sugar
Cane
Sugar cane,
a tropical grass, can be grown under a variety
of soil and climatic conditions. Alluvial plains
containing large quantities of humus, as in St.
Catherine and lower Clarendon, are very suitable.
Flat or gently undulating lands are best; flat
areas will render more easy cultivation by hand
or mechanical equipment and transportation of
the reaped canes to the factory.
Sugar cane cultivation varies from district to
district according to the existing conditions
but the trend is for more mechanisation as dependence
on hand labour grows less and less.
One important factor in sugar cane cultivation
is sunshine, which determines to a large extent
the sucrose content of the cane juice. Flat lands
always have more hours of sunshine than hilly
districts. Before the introduction of machinery,
the small factories which crushed cane by windmills,
were usually situated on elevated land to make
use of all the available wind. In recent times,
however, the large central factories like Frome
and Monymusk, are situated in areas to which transportation
is relatively easy.
Sugar cane is propagated by cuttings, and planted
in rows about 1.5 metres (4 ft 6 ins) from each
other. The crop requires intensive cultivation
in order to produce satisfactory results. Moulding
should be started when the plants are about 0.5
m (18 ins) high, and the fields must be kept free
from weeds. While irrigation is necessary on most
estates, good drainage is essential and the soil
must not be waterlogged. It is essential that
the fertility of the soil be maintained by the
addition of vegetable matter or artificial fertilisers.
The crop takes from twelve to eighteen months
to reach maturity, and the first harvest reaped
from the cuttings which have been planted are
called plant canes. If the roots or 'stools' are
left in the ground, new shoots will grow from
them. These are called rations. Fresh cuttings
should be planted after the second ratoon since
the yield per acre diminishes rapidly after that.
By-products of the sugar industry are rum, for
which Jamaica is world-famous, molasses, molascuit,
a cattle food made of the interior cellulose fibre
of the sugar cane, power alcohol, and various
forms of bagasse, such as the fibreboard known
as 'Celotex' and paper pulp.
Citrus
The varieties of citrus may be divided into three
classes: the orange, grapefruit and lemon. In
the orange group, the types are the Common Jamaica,
grown chiefly for home consumption;the Valencia,
the fruit of which does not fall off the tree
after ripening; the Navel, the Ortanique and the
Seville. In the grapefruit group are the Marsh
Seedless, the standard variety grown for export,
the Silver Cluster and Duncan which contain many
seeds, the Ugli, chiefly exported, and the Chadwick
.
The
best soils are fertile, well-drained, medium-textured
loams with no impervious layer near the surface.
Rocky hillsides with shallow soil exposed to erosion
should be avoided. In preparing the land special
consideration must be given to the avoidance of
pests. There should be about 125 cm (50 ins) of
rainfall with even distribution throughout the
year. The trees should be protected from prevailing
winds and, if there is no natural shelter such
as a mountain range or a belt of forest, windbreaks
should be established before the orchard is started.
Propagation is by budding.
Bananas
Bananas are cultivated in nearly every moist tropical
country, and constitute a substantial part of
the local diet. Jamaica is one of the leading
banana-exporting countries in the world.
Deep loam with a fair proportion of sand is the
best type of soil for banana cultivation. There
should be good under-drainage, for the roots are
very susceptible to water-logged soils. In Jamaica
bananas are grown on various kinds of soils, but
especially on the three most important types
the alluvial soils, the shales and the red limestone
soils.
The water requirement of the banana is very great.
Whereas St. Mary and Portland with their abundant
rainfall provide excellent banana lands, the St.
Catherine plains have to be extensively watered
by artificial means to grow bananas. A high temperature
is necessary, and the plant thrives best in tropical
and more so in equatorial climates. Clean weeding
should not be practised.
The plants are propagated by shoots or 'suckers'
which used to be spaced 3 m by 3m (9 ft by 9 ft)
apart. However, closer planting with the use of
fertilisers is now being done to get more yield
to the acre. The plant does not offer resistance
to heavy wind and entire crops are destroyed in
a hurricane.
Erosion is an important factor to consider in
banana cultivation, for about 80 per cent of Jamaica's
bananas are produced on sloping land. The plant
does not provide protection against soil erosion,
because its important roots occur in the top O.25
to 0.66 metres (10 to 24 ins) layer of soil. Extensive
conservation measures, therefore, have to be adopted
on sloping ground.
Panama Disease and Leaf Spot are the two main
diseases which affect the plant. The Lacatan variety
is immune to Panama Disease and while Leaf Spot
is still a serious problem it can be effectively
checked by careful spraying. The main pest is
the banana weevil borer, which can be controlled
by strict field sanitation.
Coffee
Apart from
its great demand on the world market, coffee is
important as a 'money crop' because it can be
cultivated on slopes, too steep for other crops;
it can be picked by unskilled labour, and it keeps
well and is not damaged by rough transportation.
Coffee grows with best results in a warm, moist
climate, and on rich, well-drained soils with
an abundance of decayed vegetates mainly a crop
for high elevations and since it should be protected
from wind, the leeward slopes of mountains are
more suitable than the windward slopes. The large
coffee growing districts of St. Andrew are on
the southern slopes of the Blue Mountains, thus
sheltered from the northeast trade winds. Three
chief chemicals should be present in the soil--
potash, which is needed at all times, nitrogen
and phosphoric acid.
One of the most important aspects of coffee cultivation
is pruning, which gets rid of old wood and encourages
new branches for blossoming and crop-bearing.
Blue Mountain coffee is of very fine quality,
and is well known throughout the world.
Cocoa
The original home of the cacao or cocoa
tree is that part of South America watered by
the Amazon and Orinoco rivers. In its wild state
the cocoa tree grows under the shadow of taller
trees. The tree which is about 3 to 10 metres
(1530 ft) high, begins to flower when it
is about four years old, with blossoms arising
from the trunk and branches which are more than
a year old. Only 5 per cent of the blossoms usually
set fruit, and the pods take about five months
to ripen. Each pod contains twenty to forty-five
seeds or 'beans'.
The varieties chiefly grown in Jamaica are the
Forastero and Criollo. The cocoa tree will grow
in a great variety of soils, provided they are
deep and well-drained. The mean shade temperature
should be about 26C (80F) with an allowance of
7 (15F) above and below this point.
Next to climate and soils, shade is the most important
requirement for cocoa. In Jamaica cocoa without
shade suffers from tieback caused by the direct
rays of the sun and by thrips, an insect attracted
to unshaded cocoa. The most suitable shade trees
are the quick-stick or St. Vincent plum and the
locust or cocoa oak. The guango or immortelle
are also used. Temporary shade may be provided
by plants such as the banana, pigeon peas and
castor bean. Cocoa trees should be planted four
metres by four metres (12 ft by 12 ft) apart.
One important factor is that the cocoa tree suffers
from the drying effect of continuous winds which
injure the small, tender flowers and dry up the
young pods. In the north of Jamaica where the
northeast winds are prevalent, the cultivations
must be protected either by hills or artificial
windbreaks. The most important cocoa area in Jamaica
is the parish of St. Catherine, which is sheltered
from the trade winds by the central mountain range.
The principal cocoa harvest occurs between September
and November, and there is a lesser harvest between
February and April. Pods should be carefully cut
to prevent damage to the tree. After having been
processed extensively, the beans are finally used
to make cocoa and chocolate.
There are four fermentaries in Jamaica for processing
cocoa. They are situated at Richmond in St. Mary,
Morgan's Valley in Clarendon, Haughton Court in
Hanover and at the Cocoa Board's headquarters
in the Industrial Estate in West Kingston.
Coconuts
The coconut, the most widely cultivated
of all the palms, grows best on alluvial soil
which allows for free drainage. Coconut palms
grow on many different types of soil but they
give best results where the soil is friable. Lands
near the sea-coast are therefore the ideal soil
for coconuts since the coconut is not susceptible
to ordinary wind and requires heavy rainfall.
The crop will thrive inland, however, where soil
and rainfall conditions are suitable.
Formerly coconuts used to constitute a major part
of Jamaica's export produce but now that the edible
oil and soap industry had been developed, most
of the annual crop is used in local factories.
In the nineteen-seventies, the tall coconut trees
have been afflicted by a scourge called Lethal
Yellowing. Many thousands of trees were destroyed
by this disease but replanting of dwarf coconut
trees, which are immune to the disease, has progressed
rapidly.
Forests
The term forest here applies to
lands with trees whose crowns cover more than
20 per cent of the land area. The Jamaican forests
consist of a mixture of mainly evergreen, broad-leaved
tree species, with a sparse occurrence of the
more valuable species. This is a typical feature
of tropical forests. In the 1970s as much as 24
per cent of the land area (300,000 hectares/660,000
acres) was classified as forest and about 20 percent
(270.000 hectares/560,000 acres) could be called
wooded lands.
Jamaica is a very mountainous country, with more
than two-thirds of the land mass above 300 metres
(1,000 ft) in elevation. The value of the forest
cover is therefore extremely important in protecting
the soil from severe damage by heavy rainfall
and in conserving moisture which is allowed to
percolate slowly into the natural aquifers and
thus ensure the continuous flow of the major rivers
and streams.
In addition, these upland forests have a natural
scenic beauty which is increasingly receiving
the attention of the populace for recreational
purposes. A number of recreational areas have
been developed for public use within the national
forest estate of 130,000 hectares (274,000 acres).
This large area of forest land is managed by the
Forest Department, which was formed in 1942. The
Department has the responsibility of conserving
and developing Government-owned forest lands.
Since its formation, the Department has been encouraging
private afforestation while carrying out its own
afforestation programmes. There are now approximately
over ten thousand hectares (20,000 acres) of Government
forest plantations, mainly Caribbean Pine (Pinus
caribaea) and Blue Mahoe (Hibiscus elatus).
Recent studies carried out jointly by the Forest
Department and UN/FAO experts confirm that the
country has considerable potential to supply its
future timber and wood requirements by large-scale
plantation of Caribbean Pine.
Jamaica's forests have always been exploited for
timber but in recent years extensive clearing
for agriculture, including coffee, and unrestricted
cutting for other purposes have severely reduced
the forest lands, leaving large areas of 'ruinate'
or understocked natural forests. Increased afforestation
programmes are now being introduced together with
greater controls in the affected areas.
THE
FISHING INDUSTRY
Up
to 1949, the Government had taken practically
no active part in the Fishing Industry. In December
of that year the Fisheries Division was set up
as a sub-department of the Forest Department.
It was later transferred to the Department of
Agriculture, which later became the Ministry of
Agriculture and Lands.
Since December 1949, when the Fisheries Division
has been actively engaged in the development and
promotion of the Jamaican fishing industry by
provision of training and technical advice to
fishermen, conducting exploratory fishing to test
the potential of fishing grounds, provision of
easy credit for outboard motors, duty-free outboard
motor fuel, encouragement of fishermen's organisations
such as cooperative societies, provision of outboard
motor fuel outlets, gear stores, sanitary conveniences
and lighting on beaches, and by the preparation
and execution of schemes aimed at increasing the
quantity of fish landed in Jamaica.
This Division is also responsible for the inland
or fresh-water fisheries, and has been encouraging
the cultivation of fish in ponds, tanks and marshes
by provision of fingerlings and advice on pond
management. Through this programme of fish-farming
and the stocking of rivers and irrigation canals
with fish, previously useless land has been put
to more productive use, and a major source of
cheap animal protein has been provided. This has
had a significant effect on improving the diet
of the people in several parishes of Jamaica,
particularly St. Catherine, St. Elizabeth, Clarendon
and Westmoreland. Since the 1980s, the inland
fishing industry has developed to the extent that
the import of fish for the tourist industry has
been reduced. Up to the present, the inland fishing
industry has shown an average of 4% annual growth.
In relation to the marine fisheries, the programmes
carried out by the Government have produced results.
Because of the training and advice given to fishermen,
the fishing industry has extended its limits in
that Jamaican fishermen are now able to fish at
distances of up to 480 kilometres (300 miles)
away from Jamaica, whereas 25 years ago they fished
barely 16 kilometres (10 miles) away from shore.
Today, fishermen are using synthetic materials
for making their boats and equipment, polythene
rope has almost completely replaced Cayman rope
among trap and pot fishermen, nylon and monofilament
netting is increasingly taking over from cotton
netting. As it becomes more difficult to obtain
the cotton and guango trees from which canoes
were traditionally made, more and more canoes
made of fibreglass are appearing on our beaches.
As a result of Government assistance in obtaining
credit, our fleet of large decked vessels grew
in numbers and the fishing industry flourished.
In recent years, however, the industry has been
experiencing difficulties as a result of a reduced
stock of fish and competition from foreign vessels
fishing in Jamaican waters.
