Jatropha Curcas general data

Jatropha plantation and bio diesel production can be a highly rewarding activity. The plant comes into bearing the first year onwards and stabilizes by the 2nd or 3rd year. It gives a yield up to 40 – 45 years. Normally, one-hectare of plantation yield is in the range of 3 to 18 tons of dry seeds and these contain 35-38 % of oil, depending upon the local climatological and hydro-geological conditions.

There are approximately 170 known species of the Jatropha plant and all belong to the Euphorbia family. The most commonly planted one is the species Jatropha Curcas L, also known as "physic nut". We have collected the gene from difference areas in Indonesia for our R&D to produce this high yield species by our team of scientists. All plants are fully adapted to the Indonesian climate and soil conditions and disease free. These strong mother plants were collected in the wild in Indonesia where the plant already was growing at large scale from 1940 and earlier'.

The Jatropha is a related species of the castor plant also named mammon plant which is producing the castor oil. The plant and its seeds are non edible (toxic) to humans and animals. The toxicity is mainly due to the presence of "curcin" and "deterpine". When steamed or stewed, the cooking/heating process will neutralize the toxic elements in the seeds and cake. In case of applying the seedlings method, the Jatropha plant is edible (non-toxic) in the first 3 months; since the toxic material has not been develop yet. In this period of early planting stage, it should be protected from animals.

Jatropha is not a self propagating plant like weed, it has to be planted. Jatropha does not thrive in wetland conditions. It has been observed that Jatropha requires sunlight for maximum seed production.
