520			_aThe relationship between girth and the above ground biomass was studied in two clones, with varied growth habits, of Hevea brasiliensis. The clones chosen were RRIM 600 and RRII 118. A set of relationships were developed using the biomass as a power function of girth for different age groups from first year after planting upto fifth year. The regression equations were found non-significant for individual clones as well as for years from second year onwards. A general equation was thus developed and is given as biomass in g(W)=2.278479 X2.2683(where, X is the girth at 15 cm height from bud union). The relation is found to be good fit from 16 cm or more girth, and is location specific.
