JATROPHA CULTIVATION TECHNOLOGY
THE
PRODUCTIVE PLANTATION OF JATROPHA CURCAS
The practices being undertaken by the
Jatropha growers currently need to be scientifically
managed for better growth and production. The growth
and yield of Jatropha could be improved through
effective management practices.
The key factors that can influence
the oil yield of Jatropha Curcas are:
1. Climate
2. Quality of the soil
3. Irrigation
4. Weeding
5. Use of fertilizer
6. Crop density
7. Genotype
8. Use of pesticide
9. Inter-cropping

SUCCESSFUL PRECULTIVATION IS CHARACTERIZED BY
•
High germination rates of seeds
•
High sprouting rates of cuttings
•
High survival rates
Basing the propagation method on rainfall conditions
plays a decisive role in the survival and properties
of the plant in field.
•
Method of cultivation should be chosen on the basis
of
•
Maximum survival rates
Intended utilization of the plantation
1. For quick establishment of hedges
and plantation for erosion control, directly planted
cuttings are best.
2. For long-lived plantations for
vegetative oil production, plants propagated by
seeds are better.
3. With better rainfall conditions, the plantations
could also be established by direct seeding.
Direct seeding, precultivation of seedlings, easily
propagates the Jatropha transplanting of spontaneous
wild plants and direct planting of cuttings. Seed
should be collected when capsules split open. Use of
fresh seeds improves germination. Intervals of
presoaking and drying, or partial removal of the
testa are more successful than presoaking alone.
With good moisture conditions, germination takes 10
days. The seed shell splits, the radicula emerges
and 4 small peripheral roots are formed. Soon after
development of the 1st leaves, the cotyledons wither
and fall off. Further growth is sympodial
Climate
Can
withstand severe heat. Likes heating and doing well
in warmer areas. When cold will drop its leaves. It
can withstand light frost but not for prolonged
periods. The older the tree the better it will
withstand. Black frost will almost certainly kill
young plants and severely damage older plants
Quality of the soil
Best
in sandy well-drained soils. Can withstand very poor
soils and grow in saline conditions All the actors
in the Jatropha sector suggest, anyway, using
organic fertilizer in order to obtain higher yield.
Irrigation
It
handles dryness very well and it is possible to live
almost entirely of humidity in the air. - See Cape
Verde where rainfall is as low as 250 mm a year.
Differences are expressed in what is optimum
rainfall as some readings say 600 mm and some say
800 mm whilst some areas in India report good crops
with rainfall of 1380 mm. Under irrigation 1 500 mm
is given.
500
- 600 mm of rainfall is the limit. Below it the
production depends on the local water condition in
the ground
It
will also stand for long periods without water - up
to 2 years – and then grow again when rains occur
again
Pruning
– 1st prune The plants need to produce side shoots
for maximum sprouting and maximum flowers and seed.
Between 90 and 120 Days top of all plants at 25 Cm.
Cut the top off cleanly and cut top to produce 8 –
12 side branches.
It
is considered good practice. In order to facilitate
the harvesting, it is suggested to keep the tree
less than 2 meters.
Inter-cropping
Specific intolerance with other crops was not
detected. On the contrary the shade can be exploited
by shade-loving herbal plants; vegetables such red
and green peppers, tomatoes, etc.
Picking
We
have developed the harvest methodology between wet
and dry seed crush costing applicable has been
compared.
Crop
yield
It
appears very difficult to estimate unequivocally the
yield of a plant that is able to grow in very
different conditions.
Yield is a function of water, nutrients, heat and
the age of the plant and other. Many different
methods of establishment, farming and harvesting are
possible. Yield can be enhanced with right balance
of cost, yield, labour and finally cost per Mt
Seed
production ranges from about 2 tons per hectare per
year to over 12.5t/ha/year, after five years of
growth. Although not clearly specified, this range
in production may be attributable to low and high
rainfall areas.
