EUCALYPTUS PLNTATION
Eucalyptus are generally moderately large trees and attain a
height of 40-60 feet and diameter of 40-45 inch. The trunk of the tree is
generally straight and constitute half
of the total height.wood is buy back with rate of kg. 5 - 6 RS/kg 300-400 kg /tree in 4-5 yrs.one tree become of minimum 1800
-2000 RS after 5 yrs. do 1200 plant in one acre at space of 1.5 X 1.5 meetre
and earn RS 1800 from one tree x 1200 tree = 20,00000 - 22,00000 lakhs
POPLAR PLANTATION
Yield and Returns
In market, the poplar wood is sold on
weight basis. The average wood biomass per tree after six years is about 300kg
to 400kg and presently the prices vary
from Rs. 4 to Rs. 5 per kg though the highest has gone upto Rs. 6/kg. Assuming
an average price @ Rs.4/- per kg (under bark volume), the farmer can get Rs. 1800
- 2000/ tree/- over a period of six years. Income from inter-crops will be
additional which will vary depending upon the crop cultivated. The returns will
depend upon site quality, inputs, intensity of management, actual yield and
ruling market prices at the time of harvest.
Eucalyptus
is a fast growing tree and sub-species
with several varieties and hybrids. It can be planted on agricultural lands
both as monoculture and as a component of agro-forestry programmes. One of the
principal factors for its widespread introduction is the ease of cultivation.
Besides this, good germination and its adaptability to varying soil and
climatic conditions are the other important characteristics of Euca.
II.
Growth Habit
Eucalyptus
trees are generally ever green trees, new leaves appear as the old ones are
shed. It has no well defined season of growth and continue to grow in all
seasons. It attains a height of about 30 mts and more with a straight clean
bole. They have (the ability to colonize bare ground without shelter. Some of
the species occurring in extremely dry areas are no higher than shrubs. The
shrubs namely, E. erythrandra, E. burdethianaa and E. mitrata are 6-8 mts tall
with a voluminous root system. Many of these species, when cultivated under
more favourable conditions, develop into small trees.
There is
a great variation in the height of various Eucalyptus , species of tree habit
in their homeland ranging from 20-114 mts and girth up to 3- 4 metres.
In
India, the successful Eucalyptus are generally moderately large trees and
attain a height of 40-60 feet and diameter of 40-50 inch. The trunk of the tree
is generally straight and constitute
half of the total height.wood is buy back with rate of kg.5-6 Rs/kg 300-400 kg
/plant in 4-5 yrs.one plant become of minimum
1800-2000 rs after 5 yrs.

PIanting
techniques:
Eucalyptus
plantations require well drained, deep and fertile soils. Sandy soils may be
good, provided facility of adequate irrigation is available. Choice of proper
species for a particular type of site is also an important factor for the
success of an Eucalyptus plantation. Specific sites suitable for different
species.
1. Block planting
Eucalyptus
are planted in blocks either in existing blanks or on sites containing
vegetation.
In
manual planting, pits of 15 x 15 x 15 cms or 45 x 45 x 45 cms or 60 x 60 x 60
cms can be dug depending on the soil and irrigation facilities. In waterlogged
areas, planting on raised mounds up to one metre high is done in certain areas
in Punjab, Haryana and Uttar Pradesh, usually in multiple rows along roads.
2. Row planting
Row
plantations are carried out along roads, canal banks and railway lines. Along
roads eucalyptus are planted behind first row of shade trees.
Irrigation
and Interculture:
The
irrigation pattern depends on the rainfall pattern of the area, type of soil
and the objective of plantation. For quicker returns more number of irrigations
are essential which may go up to 20 in number.
Climbers
are a great menace to young regeneration and unless they are removed, they will
spread over the saplings and smother the crowns. The climbers are to be removed
along with roots, before the season of maximum growth. The heavy foliaged soft
climbers such as mucuna Diascorea spp, etc. and woody species such as Acaecia
spp., Mollettia, zizyphus spp. and Bauhinmia vahlii case also cause equal
damage. So, reguIlar weeding practice is essential for healthy growth of the
plants.
Cutting
back is usually not very effective and it is more economical in the long run.
These measures should obviously be taken before any seed has set and before the
season of maximum growth.
Thinning
should be done between 2nd- 3rd years and the effect of regular thinnings on
the yield and on the subsequent development of the crop is quite significant.
In high density plantations simple mechanical thinning may be carried out by
cutting the poor, undesirable
