Is it possible to cite this data. I have heard contraditory reports...--Agrofe 23:33, 24 July 2007 (UTC)

Bot report : Found duplicate references !

In the last revision I edited, I found duplicate named references, i.e. references sharing the same name, but not having the same content. Please check them, as I am not able to fix them automatically :)

I've cleaned this up - neither reference was used twice so I just removed the name from the second one. -- SiobhanHansa 22:34, 12 August 2008 (UTC)

Means of propagation

One part of this article says the plant is propagated mainly by seeds, another mainly by cuttings: I don't know which is correct, but right now it is internally contradictory.

A reference that is cited about propagation by cuttings is an MSc thesis, so it seems to have been necessary to study this plant at the Master of Science level to develop a technique for propagating it by cuttings. It looks as if propagation by seed is the normal method. Nadiatalent (talk) 15:36, 14 March 2010 (UTC)

Eh? This plant is easy to root from cuttings. Just 'cause someone wrote a thesis on something doesn't mean it's difficult! You could write a thesis about propagating it from seed! Hedges of this are usually made by simply sticking a stick in the ground, it should root in a few days. Let me change this... Leo 86.83.56.115 (talk) 18:07, 11 November 2017 (UTC)

Classification of seeds

Seeds are commonly classified in 'orthodox' (desiccation tolerant and long-lived), 'recalcitrant' (desiccation sensitive and short-lived) and 'intermediate' (moderate desiccation tolerant and sensitive to dry storage at low temperatures) seeds. According to section "Propagation" seeds of Jatropha curcas L. are recalcitrant, but they are neither desiccation sensitive nor sensitive to dry storage at low temperatures and thus they are orthodox seeds. —Preceding unsigned comment added by 90.136.70.180 (talk) 20:29, 31 October 2010 (UTC)

Hi, do you have a citation for that, or is this your personal experience? Nadiatalent (talk) 10:54, 1 November 2010 (UTC)

It is a typical orthodox seed. I will find a citation. Leo 86.83.56.115 (talk) 18:09, 11 November 2017 (UTC)

I've changed the info, provided many sources. It turns out that, while it has always been quite clear that the seeds show orthodox behaviour, the editor who back in 2008 copy & pasted the information from Prakash (2006), the original source used for that section, did not read the report correctly. Prakash meant oil seeds in general and his thesis described vegetative propagation techniques for three species of potential oil crops, including a possibly recalcitrant one. I will delete most of the text copied from his thesis. Of further note, in a Farmer's Guideline distributed in Kenya and online in 2007 by the South African 'NGO' Green Africa Foundation (a big player in the Jatropha game in Kenya at the time), they claimed the seed was recalcitrant. This company was selling seed to local farmers at the time, so there may have been an incentive to misrepresent the data? Perhaps they also misread Prakash? Perhaps they are the editor in question? The project was a big failure and the company gave up on Jatropha somewhere in 2012 (their websites are still up, but do not appear to function properly anymore)...

Flood tolerant?

In the discussion of growing conditions, there is no mention as to flood tolerance? In searching, I found this:

http://www.jatropha.pro/PDF%20bestanden/Growing%20Jatropha%20manual%2003%20published.pdf

which indicate that the plants can not handle flooding, they quickly suffocate. See page 13, near the bottom.

Use during WWII

The article currently has an image of a poster which is described as connected to "the compulsory planting of jatropha in Indonesia for the production of oil as machinery lubricant and fuel for the Japanese WWII war effort." There is no other mention in the article of this compulsory planting, or use during WWII. Does anyone have RS refs which cover this?Dialectric (talk) 15:31, 21 June 2016 (UTC)
