Tapping of rubber :- Introduction :- The commercial production of rubber plantation is to production of rubber there are mainly two varieties . Indian rubber ( Ficus elastica ) Brazil rubber ( Hevea brasiliensis ) among these two the indian rubber is not commercial because of its less production of latex hence Hevea brasielensis is more commercial.

Tapping It is the process of periodical removal of thin slices of bark to extract latex. Criteria considered in tapping ; The rubber trees attain tapping stage in about minimum of 7 years . Seedling must attain a girth of 55 cm and at a height of 50 cm from grond level . In case of budded plants attains a girth of 50 cm and at a height of 125-150 cm from bud union.

Rubber is obtained from latex of the plant and we can obtain latex from all parts of plant but maximum in phloem tissue/ bark of the tree.   Arrangement of latex vessel in the bark They arranged horizontally in the bark at 3-5 0 c inclination in anticlock vice direction.

PowerPoint Presentation:

Method of extraction The tapping should be done by skilled men. While tapping the depth should be 1mm close to cambium without any damage to it, Otherwise Callus formation will takes place. Tapping has to be done a slope 30 0 to the horizontal zone, in case of budded trees and 25 0 in the case of seedlings and it is done in the direction from left bottom to right.

PowerPoint Presentation:

Intensive tapping before felling of old tree is called Slaughter tapping Slaughter tapping :-   The tapping is done in early morning as it delays results in reduction of flow of latex. In the early morning the turgor pressure in the latex vessel is high. Hence rapid flow of latex takes place. Time of tapping:-

2,4D or 2,4,5T Any one of this chemical mixed with oil and pasted on the Bark 3 days before tapping, Which results in increases the latex. Trade name: Ready rub and flow more   Ethrel ( 2 Chloro ethyl phosphonic acid ) This is applied 6-7 days before tapping. Use of growth regulators in rubber tapping
