What is the yield of Jatropha in tonnes per hectare per year?
around 7 tonnes
– Jatropha trees are productive for up to 30-40 years. – 2,200 trees can be planted per hectare (approximately 1,000 per acre). – One hectare should yield around 7 tonnes of seeds per year.
Is Jatropha farming profitable?
As with many members of the family Euphorbiaceae, Jatropha contains compounds that are highly toxic. Jatropha farming is profitable as there is a huge demand for mass production of seeds for bio-diesel.
Where is Jatropha grown?
Jatropha grows in tropical and sub tropical regions, with cultivation limits at 30ºN and 35ºS. It also grows in lower altitudes of 0-500 metres above sea level (see Figure 6). Jatropha is not sensitive to day length (flowering is independent of latitude) and may flower at any time of the year (Heller, 1996).
What are the uses of Jatropha curcas?
Results: Jatropha curcas is traditionally used to treat bacterial and fungal infections or febrile diseases, muscle pain or jaundice. It is also used for obtaining new drugs through the identification of active ingredients to eliminate pathogens or inhibit signs and symptoms of human and veterinary diseases.
How long does it take to grow Jatropha?
While Jatropha curcas starts yielding from 9–12 months time, the best yields are obtained only after 2–3 years time. The seed production is around 3.5 tons per hectare (seed production ranges from about 0.4 t/ha in the first year to over 5 t/ha after 3 years).
How do you harvest Jatropha?
Cut the seedpod open carefully with a knife, slicing around the seedpod’s center. Pull the pod’s two outer shell halves apart. Pull or shake the seeds from the pod. Repeat this process with all unopened seedpods.
Which is the problem regarding Jatropha cultivation?
Unfortunately, there has been no significant progress, and Jatropha did not contribute much in the energy scenario. Unavailability of high-yielding cultivar, large-scale plantation without the evaluation of the planting materials, knowledge gap and basic research gap seem to be the main reasons for failure.
What is the common name of Jatropha curcas?
Integrated Taxonomic Information System – Report
|Synonym(s):||Curcas curcas (L.) Britton & Millsp.|
|Common Name(s):||physic nut [English]|
|Barbados nut [English]|
Is Jatropha fast growing?
This tree is a fast grower – the dwarf variety gets only 6 to 8 feet tall. It needs full to part sun and a well-drained spot. Jatrophas are drought-tolerant once established, preferring regular waterings with time to dry out in between.
How tall does Jatropha get?
about 15 feet tall
Jatropha is a tropical evergreen that has slender stems and multiple trunks. These plants can reach about 15 feet tall and have an equal spread when left unpruned.
Can Jatropha be grown commercially on marginal land?
The poor performance of jatropha under low moisture and poor soil conditions came as a surprise both to investors and governments who believed that jatropha could be grown commercially on marginal land.
What is the Emami Jatropha project?
The Emami jatropha project is located in a neighbourhood where there is historical conflict between two ethnic groups (Afar and Oromo) over grazing land. The communities in the project area are mainly pastoralists and very few of them are engaged in mixed crop-livestock activities.
Is Jatropha a ‘miracle’ crop?
Many claims have been made about jatropha as a potential biodiesel crop, and it has been hailed as a ‘miracle’ crop that can resist drought and grow well on ‘marginal’ land and help to reclaim degraded land ( FAO, 2008 ).
