ABSTRACT
Among different formulae i.e. Smalian, Huber and Quarter Girth tested for suitability for volume measurement of the same lot of Shisham logs, Smalian's formula gave the highest volume over the other two. For under bark volume measurement, percent ratio of Smalian, Huber and Quarter Girth formulae came to be 100:86:68 while Huber and Quarter Girth formulae gave 100:79 ratio, respectively. It is preferable to use Smalian's formula, which besides other advantages gives more accurate result i.e. the result nearer to the actual one. Forest Department, at Changa Manga plantation has an economic benefit on sale of Shisham timber by giving 2.54 cm bark allowance per foot girth'instead of selling it on under bark volume basis. Moreover, results revealed better quality timber production at Changa Manga as compared to Chichawatni plantation.
