This is one of 280 summaries describing key outputs from the projects
run by DFID's 10-year Renewable Natural Resources Research Strategy
Principally based on Projects R5058, R7002 and R7212. New intercropping
systems can double returns from small rubber plantations. Smallholders
in Asia— often cultivating less than two acres—produce more than
three-quarters of the world's natural rubber. But, because young trees
produce no rubber for the first 5-6 years, farmers plant bananas as an
intercrop to tide them over. Farmers in Sri Lanka now plant a third more
bananas than officially recommended and find they can make twice as much
profit. Plus, the higher density of bananas stimulates growth in the
young rubber trees. Intercropping has major potential for rural
communities of rubber growers. And, although the system was proven on
rubber and banana, it is also being applied to maize, upland rice and
tea, and in India and Ghana.
