<ul>
<li>Leaves: The leaves have significant variability in their morphology. In general, the leaves are green to pale green, alternate to subopposite, and three- to five-lobed with a<span> </span>spiral phyllotaxis.<sup id="cite_ref-Nahar_16-0" class="reference" style="font-size: 11.2px;">[16]</sup></li>
<li>Flowers: male and female flowers are produced on the same<span> </span>inflorescence, averaging 20 male flowers to each female flower,<sup id="cite_ref-Pesquisa_17-0" class="reference" style="font-size: 11.2px;">[17]</sup><span> </span>or 10 male flowers to each female flower.<sup id="cite_ref-Jatropha_journal_18-0" class="reference" style="font-size: 11.2px;">[18]</sup><span> </span>The inflorescence can be formed in the<span> </span>leaf axil. Plants occasionally present hermaphroditic flowers.<sup id="cite_ref-Nahar_16-1" class="reference" style="font-size: 11.2px;">[16]</sup></li>
<li>Fruits : fruits are produced in winter, or there may be several crops during the year if soil moisture is good and temperatures are sufficiently high. Most fruit production is concentrated from midsummer to late fall with variations in production peaks where some plants have two or three harvests and some produce continuously through the season.<sup id="cite_ref-Nahar_16-2" class="reference" style="font-size: 11.2px;">[16]</sup></li>
<li>Seeds: the seeds are mature when the capsule changes from green to yellow. The seeds contain around 20% saturated fatty acids and 80% unsaturated fatty acids, and they yield 25–40% oil by weight. In addition, the seeds contain other chemical compounds, such as<span> </span>saccharose,<span> </span>raffinose,<span> </span>stachyose,<span> </span>glucose,<span> </span>fructose,<span> </span>galactose, and<span> </span>protein. The oil is largely made up of oleic and<span> </span>linoleic<span> </span>acids. Furthermore, the plant also contains curcasin, arachidic,<span> </span>myristic,<span> </span>palmitic, and<span> </span>stearic<span> </span>acids and<span> </span>curcin.<sup id="cite_ref-Nahar_16-3" class="reference" style="font-size: 11.2px;">[16]</sup></li>

<h2 style="color: #000000; font-size: 1.5em;"><span class="mw-headline" id="Cultivation">Cultivation</span></h2>
<p style="color: #202122; font-size: 14px;">Cultivation is uncomplicated.<span> </span><i>Jatropha curcas</i><span> </span>grows in<span> </span>tropical<span> </span>and<span> </span>subtropical<span> </span>regions.<sup id="cite_ref-20" class="reference" style="font-size: 11.2px;">[20]</sup><span> </span>The plant can grow in<span> </span>wastelands<span> </span>and grows on almost any terrain, even on<span> </span>gravelly,<span> </span>sandy<span> </span>and<span> </span>saline<span> </span>soils. It can thrive in poor and stony soils, although new research suggests that the plant's ability to adapt to these poor soils is not as extensive as had been previously stated. Complete<span> </span>germination<span> </span>is achieved within 9 days. Adding<span> </span>manure<span> </span>during the germination has negative effects during that phase, but is favorable if applied after germination is achieved. It can be propagated by cuttings, which yields faster results than multiplication by seeds.</p>
<p style="color: #202122; font-size: 14px;">The flowers only develop terminally (at the end of a stem), so a good ramification (plants presenting many branches) produces the greatest amount of fruits. The plants are<span> </span>self-compatible.<sup id="cite_ref-Pesquisa_17-1" class="reference" style="font-size: 11.2px;">[17]</sup><span> </span>Another productivity factor is the ratio between female and male flowers within an inflorescence, more female flowers mean more fruits.<sup id="cite_ref-Jatropha_journal_18-1" class="reference" style="font-size: 11.2px;">[18]</sup><span> </span><i>Jatropha curcas</i><span> </span>thrives on a mere 250 mm (10 in) of rain a year, and only during its first two years does it need to be watered in the closing days of the dry season.<span> </span>Ploughing<span> </span>and planting are not needed regularly, as this shrub has a life expectancy of approximately forty years. The use of<span> </span>pesticides<span> </span>is not necessary, due to the pesticidal and<span> </span>fungicidal<span> </span>properties of the plant. It is used in rural Bengal for<span> </span>dhobi itch<span> </span>(a common fungal infection of the skin).</p>
<p style="color: #202122; font-size: 14px;">While<span> </span><i>Jatropha curcas</i><span> </span>starts yielding from 9–12 months time, the best yields are obtained only after 2–3 years time. The seed production is around 3.5 tons per hectare (seed production ranges from about 0.4 t/ha in the first year to over 5 t/ha after 3 years). If planted in<span> </span>hedges, the reported productivity of<span> </span><i>Jatropha</i><span> </span>is from 0.8 to 1.0 kg of seed per meter of live fence.<sup class="noprint Inline-Template Template-Fact" style="font-size: 11.2px;">[<i><span title="This claim needs references to reliable sources.

<p style="color: #202122; font-size: 14px;"><i>Jatropha curcas</i><span> </span>can easily be propagated by both<span> </span>seed<span> </span>or cuttings.<sup id="cite_ref-Duke_21-0" class="reference" style="font-size: 11.2px;"></sup><span> </span>Some people recommend propagation by seed for establishment of long-lived plantations.<sup id="cite_ref-Duong_22-0" class="reference" style="font-size: 11.2px;">[22]</sup><span> </span>When jatropha plants develop from cuttings, they produce many branches but yield fewer seeds and do not have enough time to develop their taproot, which makes them sensitive to wind erosion.<sup id="cite_ref-feed_23-0" class="reference" style="font-size: 11.2px;">[23]</sup><span> </span>The seeds exhibit orthodox storage behaviour and under normal treatment and storage will maintain viability at high percentages for eight months to a year.<sup id="cite_ref-24" class="reference" style="font-size: 11.2px;">[24]</sup><sup id="cite_ref-25" class="reference" style="font-size: 11.2px;">[25]</sup><sup id="cite_ref-26" class="reference" style="font-size: 11.2px;">[26]</sup><sup id="cite_ref-Duong_22-1" class="reference" style="font-size: 11.2px;">[22]</sup><sup id="cite_ref-27" class="reference" style="font-size: 11.2px;">[27]</sup><span> </span>Propagation through seed (sexual propagation) leads to a lot of genetic variability in terms of growth, biomass, seed yield and oil content. Clonal techniques can help in overcoming these problems. Vegetative propagation has been achieved by<span> </span>stem cuttings,<span> </span>grafting,<span> </span>budding<span> </span>as well as by<span> </span>air layering<span> </span>techniques. Cuttings should be taken preferably from juvenile plants and treated with 200 micro gram per litre of<span> </span>IBA<span> </span>(rooting hormone) to ensure the highest level of rooting in stem cuttings.<sup id="cite_ref-28" class="reference" style="font-size: 11.2px;">[28]</sup><span> </span>Cuttings strike root easily stuck in the ground without use of hormones.</p>

<p style="color: #202122; font-size: 14px;">There are several forms of biofuel, often manufactured using<span> </span>sedimentation,<span> </span>centrifugation, and<span> </span>filtration. The fats and oils are turned into esters while separating the<span> </span>glycerin. At the end of the process, the glycerin settles and the biofuel floats. The process through which the glycerin is separated from the biodiesel is known as<span> </span>transesterification. Glycerin is another by-product from Jatropha oil processing that can add value to the crop. Transesterification is a simple chemical reaction that neutralizes the free fatty acids present in any fatty substances in Jatropha. A chemical exchange takes place between the<span> </span>alkoxy<span> </span>groups of an ester compound by an alcohol. Usually,<span> </span>methanol<span> </span>and<span> </span>ethanol<span> </span>are used for the purpose. The reaction occurs by the presence of a<span> </span>catalyst, usually sodium hydroxide (NaOH) or caustic soda and potassium hydroxide (KOH), which forms fatty esters (e.g., methyl or ethyl esters), commonly known as<span> </span>biodiesel. It takes approximately 10% of methyl alcohol by weight of the fatty substance to start the transesterification process.<sup id="cite_ref-Nahar_16-4" class="reference" style="font-size: 11.2px;">[16]</sup></p>
<p style="color: #202122; font-size: 14px;">Estimates of<span> </span><i>Jatropha</i><span> </span>seed yield vary widely, due to a lack of research data, the<span> </span>genetic<span> </span>diversity of the crop, the range of<span> </span>environments<span> </span>in which it is grown, and<span> </span><i>Jatropha</i><span class="nowrap">'</span>s perennial life cycle. Seed yields under cultivation can range from 1,500 to 2,000 kilograms per<span> </span>hectare, corresponding to extractable oil yields of 540 to 680 litres per hectare (58 to 73 gallons per acre).<sup id="cite_ref-31" class="reference" style="font-size: 11.2px;">[31]</sup><span> </span>In 2009<span> </span><i>Time</i><span> </span>magazine cited the potential for as much as 1,600 gallons of diesel fuel per acre per year.<sup id="cite_ref-32" class="reference" style="font-size: 11.2px;">[32]</sup><span> </span>The plant may yield more than four times as much fuel per<span> </span>hectare<span> </span>as<span> </span>soybean, and more than ten times that of<span> </span>maize<span> </span>(corn), but at the same time it requires five times as much water per unit of energy produced as does corn (see below). A hectare of jatropha has been claimed to produce 1,892 litres of fuel.<sup id="cite_ref-33" class="reference" style="font-size: 11.2px;">[33]</sup><span> </span>However, as it has not yet been domesticated or improved by plant breeders, yields are variable.<sup id="cite_ref-Fairless_34-0" class="reference" style="font-size: 11.2px;">[34]</sup></p>

<p style="color: #202122; font-size: 14px;">Aviation fuels may be more widely replaced by biofuels such as jatropha oil than fuels for other forms of transportation.

<p style="color: #202122; font-size: 14px;">Myanmar<span> </span>is also actively pursuing the use of jatropha oil. On 15 December 2005, then-head of state, Senior General<span> </span>Than Shwe, said “the States and Divisions concerned are to put 50,000 acres (200 km²) under the physic nut plants [Jatropha] each within three years totalling 700,000 acres (2,800 km²) during the period”. On the occasion of Burma’s Peasant Day 2006, Than Shwe described in his a message that “For energy sector which is an essential role in transforming industrial agriculture system, the Government is encouraging for cultivation of physic nut plants nationwide and the technical know how that can refine physic nuts to biodiesel has also identified.” He would like to urge peasants to cultivate physic nut plants on a commercial scale with major aims for emergence of industrial agriculture system, for fulfilling rural electricity supply and energy needs, for supporting rural areas development and import substitute economy. (2005 from MRTV)</p>
<p style="color: #202122; font-size: 14px;">In 2006, the chief research officer at state-run<span> </span>Myanma Oil and Gas Enterprise<span> </span>said Burma hoped to completely replace the country's oil imports of 40,000 barrels a day with home-brewed, jatropha-derived biofuel. Other government officials declared Burma would soon start exporting jatropha oil. Despite the military's efforts, the jatropha campaign apparently has largely flopped in its goal of making Burma self-sufficient in fuel. (2006 from MyawaddyTV)</p>
<p style="color: #202122; font-size: 14px;">Z.G.S. Bioenergy has started Jatropha Plantation Projects in Northern<span> </span>Shan State, the company has begun planting Jatropha plants during late June 2007 and will start producing seeds by 2010. (20 July 2007 from New Light of Myanmar)</p>

<p style="color: #202122; font-size: 14px;">As of 2011 scepticism about the "miracle" properties of<span> </span><i>Jatropha</i><span> </span>has been voiced. For example: "The idea that jatropha can be grown on marginal land is a<span> </span>red herring", according to Harry Stourton, former business development director of UK-based Sun Biofuels, which attempted to cultivate<span> </span><i>Jatropha</i><span> </span>in Mozambique and Tanzania. "It does grow on marginal land, but if you use marginal land you'll get marginal yields," he said.<sup id="cite_ref-53" class="reference" style="font-size: 11.2px;">[53]</sup><sup id="cite_ref-54" class="reference" style="font-size: 11.2px;">[54]</sup><span> </span>Sun Biofuels, after failing to adequately compensate local farmers for the land acquired for their plantation in Tanzania, pay workers severance, or deliver promised supplies to local villagers, went bankrupt later in 2011, the villager farmland being sold to an offshore investment fund.<sup id="cite_ref-55" class="reference" style="font-size: 11.2px;">[55]</sup></p>
<p style="color: #202122; font-size: 14px;">An August 2010 article warned about the actual utility and potential dangers of reliance on<span> </span><i>Jatropha</i><span> </span>in Kenya. Major concerns included its invasiveness, which could disrupt local biodiversity, as well as damage to water catchment areas.<sup id="cite_ref-56" class="reference" style="font-size: 11.2px;">[56]</sup></p>
<p style="color: #202122; font-size: 14px;"><i>Jatropha curcas</i><span> </span>is lauded as being sustainable, and that its production would not compete with food production, but the jatropha plant needs water like every other crop to grow. This could create competition for water between the jatropha and other edible food crops. In fact, jatropha requires five times more water per unit of energy than sugarcane and corn.<sup id="cite_ref-57" class="reference" style="font-size: 11.2px;">[57]</sup><sup id="cite_ref-58" class="reference" style="font-size: 11.2px;">[58]</sup></p>
