In this study the authors have attempted to estimate the potential and commercial uses of the by-products of natural rubber such as rubber wood and seed. At the felling stage of rubber tree the average girth varies between 100 and 110 centimeters at a height of 125cm from ground level and the stand per hectare is estimated as 184. Accordingly, the actual potential of rubber wood fromone hectare of rubber plantation is 0.39 cubic metre of stump wood and 0.62 cubic metre of bracnch wood. The identified commercial uses of rubber wood are the manufacturing of furniture aftre treatment, making fibre boards and hard boards and paper ryon. Normally, mature rubber trees between 7-22 years of age produce seed. In case of seed the actual potential is estimated as one Kg of rubber seed consists of 205 seed at an average weight of 4.87 gms. Assuming 350 trees per ha. after giving allowance for tree loses due to natural factors 150 Kg of seed can be procured. Rubber seed is mainly used for agricultural as well as industrial purposes. In the agricultural, it is used for nursery purpose while for industrial purpose it is processed as oil after crushing the decorticated and dried kernel. The oil so crushed is used for manufacturing of soap, Alkyd Resin, paint etc. The cake is used as manure and cattle/poultry feed.
