Overview

The Smallholder Rubber Agroforestry System (SRAS) Project in Indonesia has identified the components of several improved rubber agroforestry systems (RAS) that maintain the economically and ecologically advantageous aspects of jungle rubber, with indications that the level of rubber productivity will be comparable to that of monoculture rubber garden plantations. The components of the improved rubber agroforestry systems require only low to medium input levels but will elevate and diversify farm income through the use of rubber clones and associated perennial crops (viz. timber, fruits, pulp trees and rattan).

The relative universality of RAS and its high potential of adaptability to local conditions and markets make them attractive and affordable for many farmers throughout rubber producing areas worldwide.

 

 
 
         

RAS 1. Productive jungle rubber

In RAS 1 Natural vegetation re-growth is promoted between rows of rubber trees for maintaining favorable conditions for rubber growth while keeping noxious weeds like Imperata cylindrica under control.

RAS 2. Complex rubber agroforestry system

Farmers often prefer a mixture of rubber and other crops. In RAS 2, fruit trees and other crops can be grown between rubber rows with two cycles of upland rice, and then other crops such as chilly, maize and banana are planted in the first period. In this systems, high input on the soil were given since the food crops were planted in the first 2 years of rubber plantation.

RAS 3. Reclaiming Imperata grasslands

RAS 3 is developed for rehabilitating Imperata grasslands with clonal rubber. In this system, legumes and other cover crops or fast growing trees are planted between rubber rows to control Imperata weed.
