Jatropha Cultivation and Oil Production - Bangladesh Agricultural University

  1. 1. Jatropha Cultivation and Oil ProductionDept. of Farm Power and MachineryBangladesh Agricultural UniversityMymensingh-2202
  2. 2. IntroductionConventionally, biodiesel is produced from different types of vegetableoils and animal fats. However, most of the vegetable oils, which are usedfor biodiesel production, are edible oils and therefore, there is competitionwith other food sources.Jatropha, a tropical plant yields a considerable amount of non edible oilwhich can be converted to biodiesel. The Jatropha oil can beused as a direct replacement for kerosene for cooking and lighting, as anengine fuel.Different parts of Jatropha have medicinal values. Each and every part ofthe tree from roots to the leaves can be used for various purposes e.g. tomake antibiotics, medicine for skin diseases treatment and others.
  3. 3. OccurrenceJatropha originates from Mexico,central America and South Asiabut has spread all over the world and is mostly used for hedges.Family: EuphorbiaceSpecies : Jatropha curcasEnglish name: Physic nut, purge nut, pig nut, fig nut, JatrophaLocal names:Bangladesh- Sadamandar/ Erenda/ JamalgotaMali- PourghereIvory coast- BaganiSenegal- TabananiTanzania-MakaeanIndia- RatanjutZambia- BembaZimbabwe-ShonaSouth Africa- Venda/Swahili
  4. 4. AgronomyGermination: With good moisture conditions the germination of the seedtakes 7-10 days. The shell splits and the radicula emerges and four peripheralroots are formed.Flowering: By cutting the planted branch takes 3-4 months or by seedling theplants take one year for flowering.Propagation: Direct seeding, Tansplanting, Direct planting( cutting), Tissueculture for seedlings(?)Intercropping: Without cutting the lateral roots, inter cropping as maize,Indigo, Lentill, Wheat etc can be successfully grown and farmer will get extraincome.Irrigation: There is scope for increasing yield of seed by practicing suitableirrigation method.PruningOnce a year
  5. 5. Jatropha - composition Jatropha-capsules 1000kg Minus capsule sheaths (35%) 350kg Seeds 650kg Minus seed shells (35%) 228kg Kernels 422kg Oil (58%) Seed cake (42%) 245kg 177kg

  7. 7. Critical considerations for Jatrophaplantations Country-level legislation on cultivation and bio-diesel use Use and reclamation of currently uncultivable land Working capital inputs should be understood Technology should be tuned to maximize income with minimum inputs Decentralized biodiesel production where it is grown Marketing of bi-products
  8. 8. Possible areas of the Jatropha cultivation in Bangladesh 1. Highland including hilly areas covers altogether about 4.2 million hectares are suitable for Jatropha cultivation. 2. Char land 3. Road sides 4. Railway sides 5. River bank 6. Forest areas Source: Benchmark soil of Bangladesh: Morphology, characteristics and Jatropha cultivation area classification for research management GIS Laboratory publication No.4.
