A rubber tree (Hevea brasiliensis Muell. Arg.) experimental plot was established in the Caraguatatuba area (coastal area in the state of São Paulo) to study its adaptation to this new habitat, as well as to determine the rubber yield in the early tappings. This pilot planting, the first in the area, has shown excellent growth and given better than average rubber yields. The product obtained was submitted to technological test and proved to be of superior quality. The results obtained in this experimental planting indicate that the rubber plant can be grown and explored successfully in that region.
