Introduction. Malaysia, Indonesia, Thailand and Africa are the main rubber producing countries. Natural rubber for commercial production is available from Manihot glaziovii (cera rubber), Ficus elastica (India rubber), Castiolla elastica (Panama rubber), Parthenium argenatum (Guayul), Taraxacum koksaghyz and Hevea brasiliensis (Para rubber) and among them, Hevea brasiliensis is the most.

Natural rubber, also called by other names of India rubber, latex, Amazonian rubber, caucho or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus nd and Indonesia are two of the leading rubber producers.

Types of polyisoprene that are used as natural rubbers are classified as elastomers. The soil pH of to is best for rubber cultivation. For good aeration and root growth, water table should be below at least 1 meter depth in the soil. Land Preparation in Rubber Plantation: The main field should be cleared of wild growth and pits with dimensions of cm x 45 cm x 60 cm should be dug along the contour @ suitable.

Para rubber (Hevea brasiliensis) Cultivation, Production and Trading of Para rubber Raw Materials in the Greater Mekong Sub-region (GMS) Somkiat Kasikranan1 Abstract The Greater Mekong Sub-region (GMS) consists of Thailand, China, Vietnam, Laos, Myanmar and Cambodia.

These countries have turned to be important Para rubber raw materials exporters. After a general introduction to the Mitzic rubber plantation in Gabon, a detailed description is given of the planting methods used, including the preparation of budwood gardens, nurseries, hot beds and grafting methods.

Small farms often suffer from a lack of budwood. Grafting experiments were conducted to find an alternative to budwood from a budwood garden. Rubber - Rubber - Processing: Rubber processing consists of four basic steps: (1) mastication, when the elastomer is sheared and the molecules are broken down to give easier flow, (2) mixing, usually carried out immediately after mastication, when additives are incorporated, (3) shaping of the viscous mass, for example, by extrusion or molding, and (4) curing, when the polymer molecules become.

SOILS, PLANT GROWTH AND CROP PRODUCTION - - Growth and Production of Rubber - Willy Verheye 1. Introduction Rubber (Hevea brasiliensis) is a fast-growing upright tropical tree crop which is mainly cultivated for its production of latex, a milky plant liquid, which serves as a basis for various rubber products.At the time of preparation of nursery beds, 25 kg of compost or well-rotten cattle manure and kg of powdered rock phosphate (20% P 2 O 5) are incorporated for every m2 of nursery bed.

When nurseries are established in newly cleared forest areas rich in organic matter, compost or cattle manure need not be applied during the first year.Land Preparation 1. In the area with big trees, or in second growth forest, clear the under growth first to facilitate cutting of bigger trees, then cut into logs the large trees and remove these from the site.
