ABSTRACT :
Rubber under current plantation practices requires a period of about six to seven years to attain a 'tappable' 50 cm girth. The extent of this unproductive phase is mainly governed by the inherent clonal characteristics, the soil and the nature of agronomic and management inputs. Results from R.R.I.M, clonal trials have indicated that RRIM 600 can only reach tappability between sixtyseven to eighty-one months from field budding. This immature phase amounts to about 25% of the tree's productive period,, where planting follows the conventional seed-at-stake method of establishment. Attempts to reduce the period of immaturity through refinements of various horticultural techniques3 nursery practices and development of known agronomic practices have been made by many workers.
