Plantation Crops criteria importance.ppt

The crops which are perennial in nature, cultivated in a vast area for continuously and commercially, large scaly, managed by individually or a company and long time yielded are termed as plantation crops. Such as: Bamboo, betel leaf, betel nut, rubber, tea, coffee, oil palm etc.
Conditions/criteria of plantation crops:
1. It should be perennial in nature cash crops
2. It must be cultivated in a vast area of land.
3. Commercially and continuously cultivated.
4. Managed by individually or a company.
5. Long time yielded.

Importance of Plantation Crops
1. Export income: We may earn a lot of money by exporting different types of plantation crops and / or their products.
2. To decrease import cost: We may decrease our import cost through the production of different types of plantation crops such as oil palm, Rubber, coffee, cocoa and bamboo.

Scientific name: Hevea brasiliensis
Family: Euphorbiaceae
Origin: Brazil

8. Rubber
South American tropical tree
Southeast Asia and western Africa
Sturdy, quick-growing, erect tree with a straight trunk
In the wild, the trees may grow to over 40 m with a life span of
more than 100 years. However, cultivated plants rarely grow
beyond 25-30 m in height because of the growth reduction due to
harvesting of latex by tapping.
Natural rubber is obtained from the latex or milky fluid which is
formed in laticiferous cell.
These laticiferous cells remain in between cambium and phloem
of the plants.

12. History
•1770—Joseph Priestly discovered that the material
would rub out paper marks, hence the name India
rubber,
•1823—Mackintoshmanufactureswaterproof
raincoats
by coating fabric with rubber dissolved in naphtha.
•1839—Goodyear discovered vulcanization, when rubber
was heated with sulfur, rubber retained physical
properties from 0 to 100°C. This led to rubber boom.
•1898—Dunlop rediscovers pneumatic tires (Motor cars
invented in 1885).

Importance/uses of rubber

14. Use of rubber
•70% of total rubber consumption is in the
manufacture of tyres and tubes.
•About 6% of worlds rubber is used for
manufacture of foot wear, soles and heels and 4%
for wire and cable insulation.
•Other uses such as rubberized fabrics, shock
absorbers, washers and gaskets, conveyor belting ,
sports goods, vulcanized a hard high sulphurized
rubber is used in electrical and radio engineering.
Rubber powder with bitumen is used for road
surfacing.

22. 12 kg of compost or FYM and 120 g of rock phosphate in each pit before
planting should be incorporated.
A ratio of 10:10:4:1.5 NPK and Mg should be applied.
Once in April/May and another in September/October
For mature plant, NPK 12:6:6 mixture should be applied at the rate of
400 kg/ha every year in two split doses.
10 kg commercial Magnesium sulphate should be added for every 100
kg of the above mixture if there is magnesium deficiency.
Nutrient management

23. Weed management
Irrigation in during dry seasons
Mulching 1.5-2m radius; thickness 8-10 cm
Pruning for removing diseased or damaged branches, facilitating
easier tapping, and maintaining optimal tree height for
management efficiency.
Pests and diseases like aphids, scale insects, mealy bugs, mites,
leaf blight, root rot, wilting should be effectively controlled.
After cares

24. Tapping is the process of harvesting latex, the milky white fluid
found in rubber trees, by making controlled incisions in the
bark.
Trees must be approximately six years old and six inches (150
mm) in diameter in order to be tapped for latex.
A person who taps rubber is a rubber tapper.
To tap rubber, a rubber tapper must remove a thin layer of bark
on the tree trunk. If done carefully and with skill, this tapping
panel will yield latex for up to five hours.
The cut allows the latex to run down to a collecting cup. The
work is done at night or in the early morning before the day's
temperature rises so that the latex will drip longer before
coagulating and sealing the cut.
Tapping

25. I.Herringbone method: In this method oblique cuts are made on the
bark which opposite with each other. All cuts are converging to a
vertical line. The latex runs down the cut into the central one which
conducts to the cup at the bottom.
II. Spiral method:
(a) Half spiral: The half spiral may have the spiral curves on one side of
the vertical
line.
(b) Full spiral: Spiral may have the curve completely around the
circumference of the trunk.
III. V-curved method: Two slanting cuts are made like the two curves of a
“V“ which meet at the lower end where the latex receiving cup is
fitted.

29. •Preparation of fresh flower bouquet or flower
arrangement is not only a beautiful and creative
hobby but also a mean of earning good money.

•It is a mode of value addition to flowers and also
holds the key to the ultimate fate of the commercial
flower industry.

30. Cut flowers alone or with fillers can be used for making
various flower arrangements.
These flower bouquets can be given on certain
occasions like birthdays, New Year Celebrations,
Christmas, Marriage Anniversaries, and weddings etc.
These bouquets can be easily adapted to make table
center pieces.

31. Styles of flower arrangements:
Basically 2 styles of flower arrangements:
Western style or English style: Employing a ‘mass’
concept  of arranging flowers in an even symmetry.
The Eastern or Japanese or Ikebana styles: Which are
based on specific rules and angles, using less material.
Emphasis is given on spiritual and religious background and
only few flowers are used.

32. Western style arrangement
Western style is characterized by the mass of flowers and foliage arranged in various
format.
It is balanced formal style which may be for front viewing or to be viewed from all sides.

33. Types of arrangements:
Circular
Triangular
Radiating
Crescent
Hogarthian or S curve
Horizontal design

34. TYPES OF FLOWER ARRANGEMENT
Circular shape:
Arranging flower in circular design adds a
pleasing element. It is satisfying to the
viewer's eye. The circular or round shape is
loved by nature since majority of flowers lies
in this shape. In fact, its also easier to
arrange flowers in circular fashion. These
designs are constructed in low round
containers or in basket that holds water.

35. Triangular shape :
It is a most common arrangement
of flowers used in personal and
professional functions. Firstly,
height and width is fixed with
flowers and then focal point is
established. It is made in the
triangle shape and looks very
attractive. The focal point flower
will be positioned immediately
above and in front of the rim of
container.

36. Fan shape or Radiating :
General outline of the
radiating is like fan. It is a low
arrangement and it does not
interfere with conversation across
the table. It is a fan or a horizontal
in shape generally placed in the
restaurant either in buffet or on
dining table.

37. Crescent Design: The
crescent design has a
naturally free flowering
outline which has a
formal appeal. The
crescent design is
constructed in half
moon shape having a
height at the left side
being two-third the
length of the entire line
of arrangement.

38. Hogarth or 'S'
shape:
This is very graceful style of
arrangement. It is easier to make
when curved branches are used.
Once 'S' shape is made, flowers are
filled at the center.

39. Different types of Ikebana
Moribana
Nageire
Jiyubana
Zeneika
Zneibana
Morimono

40. Moribana
‘Moribana’ means piled flowers, in which
arrangements are made in shallow containers.
The flowers and branches are supported with the help
of pin holders, which are known as ‘Kensan’ in
Japanese language.
This arrangement looks very natural and is often called
as natural ‘Ikebana’

41. Moribana

42. Nageire
‘Nageire’ means thrown in and flowers are arranged in
upright containers.

44. Juyubana
‘Juyubana’ means free flowers, which can be arranged
both in ‘Moribana’ or ‘Nageire’ styles of ‘Ikebana’.
Wood, metal or any other material may be used in
addition to flowers.

45. Juyubana

46. Zeneika
‘Zeneika’ means abstract and this style does not
simulate nature.
