According to this study, the wood production potential of rubber in northeastern Thailand can
on suitable sites be comparable to that in the South. The highest wood production potential
among the areas of present study lies in Nong Khai, where environmental conditions,
apparently the rainfall, appear to favour rubber-growing. Between Buriram and Chachoengsao
there were no marked differences in plantation performance in terms of wood production, but
even in these areas the wood production potential is not very far from that in Nong Khai.
However it has to be underlined, that the possible profitability of a rubber plantation in the
Northeast is mostly dependent on the capability of trees for latex production in a marginal
environment, at least in the present market situation. This was beyond the scope of this study,
and therefore recommendations can only be given concerning the overall performance and
wood production of rubber.
