Punam Thapa, Ram Asheshwor Mandal , Ajay Bhakta Mathema and Dinesh Poudel

Abstract:
Background and Objectives: Growth performance of any tree species is a major parameter to determine the felling rotation of that species. The growth of Aquilaria malaccensis has not assessed so far. Thus, this study was aimed to assess and compare the annual increment of height, basal area and volume and also, evaluate the economic potentiality of this species. Materials and Methods: The private plantation forest of Bharse, Gulmi Nepal was selected for the study site. Stratified random sampling was carried out based on the good, medium and poor site. Total 150 plants were measured and plant’s age were recorded asking with the farmers. The diameter and height were measured by using D-tape, Abney’s level and simple tape. The collected data were analyzed by using descriptive statisics and cost benefit analysis as well. Results: The result showed that mean annual diameter increment was 0.582, 0.36 and 0.31 cm. Mean annual height increment was 0.86, 0.69 and 0.50 m. Mean annual volume increment was 0.0000456, 0.000282 and 0.000308 m3 and mean annual carbon increment was 0.19, 0.12 and 0.13 t ha1 at age 6, 9 and 12 year, respectively. All the parameters were in decreasing trend with an increasing age in very good site. If Aquilaria species is considered as other local species and then the selling amount would be US$1377.27, the net profit after inoculation of the plant and selling the product would be US$489345.45. Estimated benefit cost (B/C) ratio would be 21.97. Conclusion: The well growth and its economic potential showed, this species can be planted as commercially valuable plants. This paper will be provide useful information for scientific community and decision maker.
