Jatropha Curcas
is a perennial, small tree growing to a height of about 3-5 meters. It grows in tropical and sub-tropical regions of any
type of soil from poorest, stony to saline soils. It can survive in low rainfall conditions (200 mm) and in hot climatic
conditions. It lives for 40-50 years. Jatropha can be cultivated as a commercial crop due to its diverse uses. For
commercial cultivation, a little bit of care, some nutrition and moderately low watering could do wonders to a cultivator
with significantly low investments.
Jatropha Curcas is resistant to drought and can be
planted even in the desert climates, and it thrives on any type of soil, grows almost anywhere; in sandy, gravelly and
saline soils. It needs minimal input or management (takes less people to manage and maintain the plantration). The plants can
can survive long periods of drought. Propagation is easy, plant growth is rapid; forms a thick live hedge after only a
month's planting. Jatropha Curcas quickly establishes itself and will produce seeds round the year if irrigated and starts
yielding seed pods from the second year onwards and continues for 40 years. The seed pods are not the only valuable part
of this plant, the leafs and the bark are used for various other industrial and pharmaceutical uses.
Normally a Jatropha tree takes 18 months to two years to
produce flowers and up to 3 years to produce seeds. In actuality, many plants produce a substantial quantity of seed pods
after the first year (within 18-months of seedling plantings). You see if the small 3 month sapling is planted, then it
grows faster and starts flowering in the second year. But it is suggested that all the "first flowers" be plucked from
the plants to give it one more year for a stronger plant development, and then harvesting the seedpods during the late
second to third year. Now 3 years is not that long. For farmers, planting Jatropha represents an additional source of
income at little cost. Jatropha can either be intercropped with existing plants, effectively fertilizing the soil, or
it can be planted on unused land that poor nutrient content has rendered unsuitable for other crops.

Plantation. This plantation is located in Rajastan, India.
