The way to plant your Jatropha curcas:
1. Seed
For seedling production, select the seeds and treat them with water 6-8 hours before sowing. This is done to soften the seed coat for easy germination. Then put the seeds in the mixture of soil, sand and manure prepared in plastic bags with water. Some ratio can be use such as 3:2:1 and 2:1. It is best to avoid removing or breaking the seed coat before sowing due to risk of abnormal seedlings.
To sow the seeds, pour water while pressing it lightly on the soaked soil to prevent the seeds out from soil . The first shoot may be growth after 6-8 days. Watering the plants twice a day, morning and evening for seven days and once for the succeeding days. Make sure do not water the plants during afternoon or hot day because it can cause tip burnt. After 2 months, the sapling is ready for plantation.
2. Stem Cutting
Cuttings should be obtained from at least 8 month-old mature plant as much as possible 45-100 cm from the base of the stem. Use a saw or sharp knife to cut it. The plant should be about 3-4 cm thick and has short internodes with many eyes. Cuttings serve as an immediate source of planting material that can produce seeds in less than 1-2 years.
3. Tissue Culture
Tissue Culture is a laboratory-based procedure, which uses artificial and sterilized propagation media. This techniques actually need some skills and high cost of productions. Tissues from various parts of the plant can be used in this procedure but for easily culture,use just leaves because leaves has low maintenance. This method allows choosing desirable characteristics of the mother stock and improving the variety of Jatropha. By the way, this techniques can produce many stock of plants at the same times. Example, from one leaf, we can get many plants because tissue culture just need a few of sample to germinate the plants.

Benefits of Jatropha curcas L.
What is the benefits of Jatropha??
This is my opinion about the benefits of Jatropha..
Jatropha curcas as an energy sources for now and later on.
Oil from Jatropha can be the source for substitute diesel. As we know diesel was used for some vehicles engines and the source of diesel are decrease from years to years. So, for the alternative way to substitute the diesel problems is by plant the Jatropha trees as commercial or non-commercial. Even the cost to produce diesel from Jatropha is higher than produce diesel from itself, but this is the way that we can create diesel from plants. Beside that, the plants oil also can decrease the air pollutions cause by using diesel. For other information, diesel produce smoke that can cause higher air pollution because of carbon monoxide.
Jatropha oil also is an important product for cooking and lighting needs of the rural population, boiler fuel for industrial purposes or as a viable substitute for diesel. Substitution of firewood by plant oil for household cooking in rural areas will not only alleviate the problems of deforestation but also improve the health because of the indoor smoke pollution from cooking by inefficient fuel and stoves in poorly ventilated space or kitchen in other words. Jatropha oil performs very safely and satisfactory when burnt using a conventional (paraffin) wick after some simple design changes in the physical configuration of the lamp.
The other benefits is Jatropha curcas will starts yielding from the second year onwards and continues for 40 years. Thats why now Jatropha become the good research and the good way to overcome or to substitute diesel. Yield from Jatropha are continues and just need the low maintenance for the trees. In addition, approximately 30 to 40% of oil extracted from the Jatropha curcas seed can be used for any diesel engine without modification.

Jatropha curcas characteristics
Here I share with you about characteristics of Jatropha curcas L.
Leaves:
dark green; alternate, simple,ovate to slightly lobed with 3-5 indentations. Up to 15 cm wide. It petioles is about 10cm long.
Flowers:
yellow green in colour, borne in axils of the leaves and small. They are mostly hidden by foliage.
Fruit:
small capsule-like, round or sphere shape of fruit, and about 2.5 - 4 cm in diameter. These are green and fleshy when immature, becoming yellow to dark brown when ripe and contain 2 or 3 black seeds each about 2 cm long. The meat of the seeds is white and oily in texture and are reported to have an agreeable taste.
Seeds:
Their seeds is in the round fruits which are black in color. Their seeds are about 2cm long and 1g weight. Sometimes their weight can reach to 1.5g-1.7g each. It is depend on their seeds size. The oil of Jatropha come from the meat that located inside the seed and the capsule of the seeds is easily broken cause just thin layer.
Habitat:
Widely cultivated as an ornamental because it can be like fences. It is also planted at arid environments.

About Jatropha curcas L.
Here is my thoughts about Jatropha curcas L.
Do you know about jatropha curcas??
Jatropha curcas or jarak pagar or physic nuts is a drought resistent species which is widely cultivated in the tropics as a living fence. Why?? because jatropha is a small perennial tree or shrub from the family Euphorbiaceae. Its oil come from their seeds which is rich of oil with excellent properties as a bio-fuel that can be processed into bio-diesel.
Jatropha curcas actually originated from Mexico and Central America, but now a days, it was introduced in all tropical regions and some subtropical regions like Florida and South Africa. It is cultivated throughout the Malesian region, though especially in the drier areas. Jatropha cannot growth in the water logged area, but if it growth, it will die after that.
Goldman Sachs recently cited Jatropha curcas as one of the best candidates for future bio-diesel production. Jatropha curcas is the future expectation for the renewable oil or substitute oil maybe for oil palm and so on. However, despite its abundance and use as an oil and reclamation plant, none of the Jatropha species have been properly domesticated and, as a result, its productivity is variable, and the long-term impact of its large-scale use on soil quality and the environment is unknown. By the way, many projects and research are still running to make sure and to get the confirmation species of Jatropha curcas.
In the recent research now, what they can conclude is Jatropha curcas has the big potential to be a substitute oil in the future. In Malaysia, some industries willing to pay about RM9000/tone matrix jatropha seeds.
