1) I am please to share with you my views about Jatropha after a detailed
literature research during the last 2 years. We are about to start a work
to "domesticate" Jatropha here in Brasil.
2) Those are the figures I am using for a local project using Jatropha
curcas L.
*Planting*: 2 a 3 kg of _*seeds *_per hectare.(Approx. 1.300 seeds / Kg.).
Assume 50% of seed will not generate healthy plants.**
*Potential harvesting ( _seeds_ not fruit ) *
* 1¼ year *130 kg/ha**
* 2¼ *520 kg/ ha
* 3¼ *1300 kg/ha
* 4¼ *2600 kg/ha
* 5¼ *4160 kg/ha
* 6¼ till 30¼ year *6300 kg/ha
*Harvesting :* 1.300 a 2.500 kg _*seeds*_ per hectare third year and on
*Productivity harvesting ( man hour ):* 2 kg a 3 kg seeds/ men hour there
are no mechanical equipment for jatropha yet. Assume will maintain plant
height at 2m. at the most.
*Oil content*: 5kg a 5,5 kg of seed has 1,25 litres a 1,48 liters of oil.
( 25% up to 35% content of oil )To run calculations be conservative like
i am as of now. There are no scientific hard data on this . First large
experiment is being conduct by Daimler Benz at Gujarat, India .So far so
good.
<>*__**__**__*Oil pressing efficiency: *__* 80 % o the potential oil (1,0
liters a 1,19 liters per hour ) (semi-industrial)
Cleaning efficiency: about 90 %
Transesterification: about 97% efficient
You have to dry the fruit in the shadow. Peel it clean the seed and than
press it properly. *Very important to press it properly and degum the pure
oil in order to get a good biodiesel at the end. There are few critical
tricks.*
Pls note my numbers are *conservative not pessimistic not optimistic*. I
contacted Africa, Germany ( Gtz, Reinhard at Hoekeheim University, etc. )
India ( Dr. Satish, etc. ) and Nicaragua and came up with above figures.
Actual numbers will be better than those prior indicated so you can run a
sensitivity for a 10% increase on final number of biodiesel.. Actual
numbers will be in this range
Saludos y Feliz a–o a todos

Dear Crystal:
could you please tell me the Jatropha nuts oil production in
litres/hect or gallon/acre?.
Tks,
Francisco.
Have a look on Journey to Forever,
http://www.journeytoforever.org/biodiesel_yield.html. The values here
correspond with values I've seen from a few other sources.
Regards,
Andrew
