Representing more than 80% of the total rubber areas, smallholder rubber plantations and its system, in Indonesia, are very unique in the world. The system, often referred to as "jungle rubber" is multi-strata in nature, and rubber is not the only crop harvested from the system but many other timber trees (usually through natural regeneration), fruit trees and annual crops are inter-cropped. These multi-strata systems have multiple functions - income source for many smallholder farmers, biodiversity and water conservation and carbon sequestration. Large efforts have been done by the Indonesian Government to improve the rubber productivity of traditional cultivation system by converting to more intensive monoculture systems. However, the rate of adoption of this technology is very slow considering the area of rubber in Indonesia. Taking into account the positive aspects of traditional rubber agroforestry ICRAF, CIRAD and IRRI worked jointly to develop and field test various improved Rubber Agroforestry System (RAS) that can provide smallholder farmers more appropriate alternatives to monoculture rubber. In all trials, recommended germplasm of rubber clones is used instead of conventional rubber seedlings. A network of trial-cumdemonstration RAS plots has been established in different provinces in Indonesia since mid nineties. The results from the wide network provided various adaptations; especially in terms of management intensity (weeding, fertilizer application) made by farmers and indicated feasible technology that farmers can benefit from. Rubber clones PB 260, RRIC 100 and BPM1 were compared with local seedlings in terms of plant growth. With lessons from earlier work, new demonstration plots of improved RAS have been established Aceh Barat District in NAD.
