The book has been written with the sole aim to provide information and to serve as a text book on rubber for purposes of reference and practical utility. It is hoped that this integrated and selfcontained book will meet a long felt need among students and exponents of the art and science of rubber production. Scientists and students interested in the natural rubber industry will also greatly benefit by becoming acquainted with the various activities and practices governing the production of rubber. This book has been based on currently available information and it has made extensive use of the immense experience of the scientists gained throughout the years while they were in service with the Malaysian Rubber Board (MRB).
