Jatropha Propagation

The jatropha (Jatropha curcas) or Barbados nut, developed in southern Florida and Hawaii, creates a nut yielding up to 37% oil which can be processed as a gas for regular diesel engines. This flowering shrub or small tree, indigenous to Central America as well as the Caribbean, develops to 20-feet tall. They can be propagated by home gardeners by cuttings or seeds. Laboratories that are commercial propagate them using tissue cultures.

Obtaining Seeds

Jatropha seeds can be obtained by you from industrial suppliers. For those who have a tree, harvest the jatropha fruits when they’re about 1-inch long and yellow to brownish. Let them dry in the sunshine, then grind them to eliminate the hulls. Winnow the seeds by throwing hulls and seeds to the air on a windy day. Select plump store and seeds . Jatropha seeds remain viable for up to 1-2 months, having a fall in germination to 80-percent after six months and have a rate of 90% or or more.

Propagating by Seeds

Prepare a planting bed in a area containing equal elements of sand, soil and manure. Soak the oily and black seeds. Press a seed onto water- soaked soil that is amended. Water the seed a day for a week. The shoot should seem after six times. Water everyday after the first week. The seedlings should be prepared to transplant after 8 weeks. Plant in rows at least 6 feet apart with 6 feet between rows.

Propagating by Cuttings

Obtain cuttings from a jatropha tree which is creating shoots and at least 8 months old. Select a shoot that’s 18 to 40-inches in the root of the tree. The shoot include four to to 6 nodes and should be 1 to 1 ½ inches. Cut the root of the shoot using a saw or knife in a slant. Plant the cut part of the shoot in coir peat or sawdust in a planting tunnel or a greenhouse covered with polyethylene plastic. The temperature should be Fahrenheit with humidity between 70 to 90%. Water the planting combination however don’t saturate. Wait before the roots transplant and produce. This can be about 10 times.

Propagation by Tissue Culture

Laboratory specialists sterilize and clean jatropha nodes. They develop them in a plant growth medium and saturate the notes. Skoog in 1962. The nodes increase in a lifestyle area under mild they elongate and certainly will be rooted till.
