INTRODUCTIONINTRODUCTION
Rubber tree (Rubber tree (Hevea brasiliensisHevea brasiliensis Mull.-Arg) was Mull.-Arg) was introduced into Vietnam by Dr. Yersin, French introduced into Vietnam by Dr. Yersin, French scientific, and has been commercially since 1906 scientific, and has been commercially since 1906 in Southeast Region. in Southeast Region.
By 1976, rubber area was 76.600 ha only By 1976, rubber area was 76.600 ha only produced 40.200 ton (0,52 ton/ha). Inproduced 40.200 ton (0,52 ton/ha). In 2007, total rubber area accounted upto 549.600 ha and gave the production 601.700 tons (1,612 ton/ha)
