The first seeds come wihin 6 months of growing the J plant, but agro experts recommend that you wait for a least 2 years before you start harvesing the seeds. Oil Yield can be very poor if you harvest seeds too early. In well-irrigated conditions, J has also proven to be disease-proine, it is best grown in dry arid condition like those prevaling in Maharashtra's Vidarbha or Gujarat's Kutch regions.

There is a large market for oilseeds (and the oil). Biodiesel plants are in operation in some states and there are several traders who are prepared to buy the oilseeds. Needles to say, it is the cart or horse story, and it will take some time for market conditions to consolidate.

It does not make sense for individual farmers to buy presses to crush oilseeds. Oil crushing is a well-established industry in most parts of India and in most places, crushing it as a "job work" is preferred. In any case, crushing machines are not expensive and are easily available across India. Prices vary depending on capacity.

I suggest NOT to use a good farm land for jatropha cultivation. The tree can be planted in wastelands where the hitherto barren lands can be used to generate some income and the attraction of it as a commercial crop lies mainly in the fact that it is non-edible oil and that there are plants being setup for exclusive purpose of making bioD from Jatropha.

The edible oils are already more expensive than diesel so they cannot be used.

Soya oil has been used in the US but their economics were different.
