One of the few tree that has green canopy in summer and fragrant flowering. Its seeds are bitter and have 30%+ oil.Yields range between 10KGs to 50KGs per trees I have done extensive domain data mining and would be happy to interact with all interested.

In fact, already in use in many locations.surfie999@gmail.comhttps://www.blogger.com/profile/05868151801037588945noreply@blogger.comtag:blogger.com,1999:blog-36976850.post-43750684515363710182010-11-29T23:25:36.487+09:302010-11-29T23:25:36.487+09:30Jatropha is a plant producing oil-based material t...Jatropha is a plant producing oil-based material that is easy to live anywhere so it is not difficult to provide learning for farmers dipedalamanricardhttp://www.biocommodity.comnoreply@blogger.comtag:blogger.com,1999:blog-36976850.post-37373292234803928302008-11-13T09:56:00.000+09:302008-11-13T09:56:00.000+09:30A response to DonI too have used Vetiver extensive...A response to Don<BR/><BR/>I too have used Vetiver extensively in both Australia and mostly Asia. NEVER found it invasive, and like you my experience with the species covers about 20 years. Most Australian states do not ban it.<BR/><BR/>As for Jatropha curcas, I think the jury is still sitting regarding weediness. Weediness as a concept can vary....and for the inland of Australia with vast areas and few people, the cost to clean up jatropha problems now [ albeit different species] are already VERY expensive. Erring on the side of caution now for a few years might be the superior option. The debate about using J curcas is not yet over in Australia. For India, parts of Africa - it is a very likely sound biofuel crop, particularly for rural areas where local oil presses can produce fuel close to the crop areas for local use. Considerable development along these lines is already occurring.<BR/><BR/>For Australia, caution is needed. At least for now.surfie999@gmail.comhttps://www.blogger.com/profile/05868151801037588945noreply@blogger.comtag:blogger.com,1999:blog-36976850.post-54572604018964555622008-11-12T18:44:00.000+09:302008-11-12T18:44:00.000+09:30I am confused by the very negative picture of Jatr...I am confused by the very negative picture of Jatropha drawn by the WA authorities. I used that plant in Burma as a soil erosion control measure many years ago and did not see or hear of any invasive characteristics. Nor were animals and people poisoned in large numbers.<BR/>I will make it quite clear that I not involved in any jatropha enterprise and am a little afraid that it could be a bit like the ostrich and goat boom/busts in the past.<BR/><BR/>However the manner in which it has been banned from WA Australia when it seems to be relatively benign in other countries is disturbing. There is an unfortunate parallel with another plant that has been declared invasive in WA. Vetiver grass (Chrysopogon zizanioides) is a non-invasive erosion control grass that I have almost 20 years hands on experience with through about 14 countries. Here are some conversations on the Weeds CRC Enviroweeds blog: <BR/>"Date: Thu, 25 Jan 2007<BR/>From: Scott Edwards Scott.Edwards@brisbane.qld.gov.au<BR/><BR/>Can someone shed some light on which Vetiver species are invasive.<BR/><BR/>Im being told of 'sterile' Vetiver being used in large scale gully rehabilitation projects, but im not convinced. I also know of it being used in remediation wetlands.<BR/><BR/>-------------------------------------------------------------------------------------------------------<BR/><BR/>Date: Thu, 25 Jan 2007<BR/>From: "Randall, Rod" RPRandall@agric.wa.gov.au<BR/><BR/>Vetiveria zizanioides (L.) Nash now called Chrysopogon zizanioides (L.) Roberty is the ONLY Vetiveria species being used for rehab and it IS invasive. The clonal form may well be sterile but as the non-clonal form is also in Australia is a moot point and there are many sterile plants that are highly invasive.<BR/><BR/>The references below all refer to V. zizanioides as a weed in various circumstances and countries. Its not worth the risk to use this species and I will continue to argue against its use anywhere."<BR/><BR/>"Date: Fri, 19 Jan 2007<BR/>From: Danielle Frohlich danielle.frohlich@bishopmuseum.org<BR/><BR/>I'd like to get some information about the potential invasiveness of the clump-forming grass Chrysopogon zizanioides, or Vetiveria zizanoides. It is being considered for use in erosion control here in Hawaii. Since it has not yet been introduced here, we're concerned it may present yet another weed problem. Anyone have any information?<BR/><BR/>-------------------------------------------------------------------------------------------------------<BR/><BR/>Date: Sun, 21 Jan 2007<BR/>From: "Randall, Rod" RPRandall@agric.wa.gov.au<BR/><BR/>Chrysopogon zizanioides is most definitely is invasive wether it be in its seeding form, or its highly promoted clonal form." (He follows this untruth with a list of references that have all proved to be irrelevant on close examination.)<BR/><BR/>Now the USDA has given the Monto/Sunshine non-seeding vetiver grass its lowest invasiveness rating of -8. I agree with that rating as I have never seen any sign of it being invasive. It has been established on one island I am very familiar with in the SW Pacific since 1912 and has not spread at all.<BR/><BR/>This is the same invasive weed expert that is behind Jatropha curcans being declared a highly invasive plant and it being banned from WA.<BR/><BR/>Go figure.......<BR/><BR/>Don Miller<BR/>donmillernz@gmail.comUnknownhttps://www.blogger.com/profile/00735051340513430050noreply@blogger.comtag:blogger.com,1999:blog-36976850.post-3979970492455682552008-09-22T22:42:00.000+09:302008-09-22T22:42:00.000+09:30True.......And I have heard some data about a ster...True.......And I have heard some data about a sterile form that only propagates vegetatively. I have no doubt that for small farmers the plant is potentially very useful. It is questionable for Australia though with so few people to manage the inland land areas where it would be grown, if it became an escaped plant. There are many of those in Australia, and which cost a lot of $$ to manage. Introduced with good thoughts, but are now pest plants.surfie999@gmail.comhttps://www.blogger.com/profile/05868151801037588945noreply@blogger.comtag:blogger.com,1999:blog-36976850.post-26534493763677083632008-08-31T12:17:00.000+09:302008-08-31T12:17:00.000+09:30Perhaps "weedy" is EXACTLY the indicator that the ...Perhaps "weedy" is EXACTLY the indicator that the plant is suitable for mass agriculture in the location? Let's face it, a lot of farmers spend huge amounts on fertiliser and weedkillers to try and get something to grow where it doesn't want to! Perhaps there's a message there?Anonymousnoreply@blogger.com
