Abstract

            The objectives of this study were to evaluate yield and financial analysis of Eucalypt plantation in each age classes and site quality at. In addition, the optimal financial rotation was determined analyzed. The 50 samples plots with 20Í20 m2 in size were randomly laid out in order to analyzed growth, yield and site quality assessment. Moreover, the obtained B/C ratio, NPV and IRR, were employed for determining the optimal rotation.


The results showed that site quality were classified into 3 classes namely; good (SI 13) medium (SI 12) and poor (SI 11). The 4 year-old of good site quality provided the highest merchantable fresh weight of 50.24 KG.tree-1, following by 5 year-old providing the yield of 46.84 KG.tree-1. Based on the financial analysis, the 3 year old Eucalypt of all site quality provided loss. In contrast, at the 3 given interest rate of 8, 12 and 15 %,  the good site quality for 4 year-old   Eucalypt plantation provided  B/C ratio, NPV and IRR of 1.58, 1.46 and 1.38; 2,786.47,  2,078.33 and 1,623.50 Baht/rai, and  33.92%  respectively  following by 5 year-old of  Eucalypt plantation, their B/C ratio, NPV and IRR  were 1.28, 1.14 and 1.06 ; 1,383.97, 672.15 and 251.10 Bath/rai, and 17.88 % respectively.  The optimal rotation of Eucalypt was at 4 year-old for the good site. While the poor site quality is unsuitable for the investment in Eucalyptus reforestation
