One of the problem in rubber culture, is the long wait for the productive stage which usually lasts for 6 to 7 years. This period of immaturity, is a very long wait especially among the small farmers with small piece of land and with farming as the only source of income. To help ease the problem, a study was conducted at the Philippine Industrial Crops Research Institute (PICRI), from Sep 1987 to Dec 1996 to verify the effectivity of high-stumped budding as planting materials in reducing the unproductive period of rubber trees; determine the length of reduction period; and, to determine the yield of performance using close RRIM 600. Two-year old high-stumped budding of Clone RRIM as planting material, shortened the immaturity period of rubber plantation. Rubber trees were toppable 1 year and 6 months earlier, that is, 3 years and a half after planting. The average latex yield was 190.22 ml per tree in the fourth year after tapping. The average dry rubber content (drc) was 36.00 per cent
