Jatropha responds well for vegetative propagation. Propagation through
branch cuttings is not new and farmers know these technique. In fact, 90% Jatropha spread throughout the country for ‘live fence’ was by branch cuttings only. Cuttings
planted during monsoon immediately after Ist showers give better root initiation, high
survival rate and good growth performance.
i. Superior Jatropha tray/ genotypes are selected on the basis of their high seed yield and oil content. ii. From the selected tree, collect the branches having 2-3 cm diameter, put them in a bucket of water. iii. Cut them into 15-20 cm long pieces with a knife or a mini hand-saw.
iv. Dip the cuttings into a tuve rooting hormone mixture (may be commercial seradix or growth harmones like IBA or NAA of 100 ppm concentration.
v. Put the cuttings in a poly bagged rooting media (Soil + Sand in 1:1) by inserting the basal region (about 3 cm).
vi. Place the poly bags inside a closed polythene chamber or mist chamber to avoid the drying of cuttings. Allow the cuttings inside the chamber for a period of 2-3 weeks.
Rooting can be seen through the transparent polybags in about 3 weeks of time. Rooting response is always better in harmone treated cuttings than in untreated cuttings. After removing from polychamber, the clones (vegetative propagules) are to be kept out side under partial shade for 2 weeks before transferring them to the field for transplanting. Using polythene chamber or mist chamber is advantageous because the plants do not lose more water through evapo-transpiration due to checking of wind velocity, the cuttings are kept always moistened thus not allowing them to become dry and ensures easy and profuse rooting.
The cuttings are planted in the month of February-March to get best sprouting and survival. Experience gained suggests heavy mortality in cuttings if planted during rainy season.
