रतनजोत या जटरोपा की खेती  Jatropha curcus,also known as Ratanjyot or Jangli erandi, is a drought-resistant perennial plant which grows almost anywhere- in marginal/ poor soil even on gravelly, sandy and saline soils. It can thrive on the poorest stony soil. It can grow even in the crevices of rocks. It is a small tree or shrub with smooth gray bark, which exudes a whitish colored, watery, latex when cut. Normally, it grows between three and five meters in height, but can attain a height of up to eight or ten meters under favourable conditions. It has large green to pale-green leaves, alternate to sub-opposite, three-to five-lobed with a spiral phyllotaxis. The petiole length ranges between 6-23 mm. The inflorescence is formed in the leaf axil. Flowers are formed terminally, individually, with female flowers usually slightly larger and occurs in the hot seasons. Fruits are produced in winter when the shrub is leafless, or it may produce several crops during the year if soil moisture is good and temperatures are sufficiently high. Each inflorescence yields a bunch of approximately 10 or more ovoid fruits. A three, bi-valved cocci is formed after the seeds mature and the fleshy exocarp dries. The seeds become mature when the capsule changes from green to yellow, after two to...

रतनजोत या जटरोफा के बीज से बायो-डीजल कैसे बनाऐं What is Bio-Diesel Bio-Diesel is the name for a variety of ester based oxygenated fuels made from certain edible and non-edible oils like Soya, Sunflower, Palm, Jatropha, Pongamia (Karanj), Mahua etc. Pure Bio-Diesel is Biodegradable, Non-Toxic and essentially free from sulfur and aromatics. It is a renewable resource based on oil crop that are grown anew each year. It can be produced domestically, reducing our country's dependence on imported oil, thus huge savings on imports. Requires no engine modifications or changes in fuel handling and delivery systems. Bio-Diesel also provides significant lubricity improvement over petroleum diesel fuel. Most of the vegetable oils and animals fats contain triglycerides, which on simple processing give fatty acid esters, called "Bio-Diesel". The chemical reaction involving a lower alcohol (Ethanol or Methanol), producing Glycerine as a coproduct, is called trans-esterification. Jatropha Curcas (Vana Erand or Ratan Jyot)  has been found to be most suitable for this purpose because of its advantages over any other species. It can be grown as a quick yielding plant even on degraded and barren lands under forest and nonforest use, dry and drought prone areas. Oil yield per hectare is approx. 1.6 metric tons on average soil (based on 5 mt seed yield per hac)...
