Abstract

Growth, above-ground biomass, litterfall and net primary productivity of Eucalyptus camaldulensis Dehnh. aged 4 years were estimated in the spacing trial plots (1x1, 1x2, 2x2, 2x4, 4x4 and 4x8 m) at Ratchaburi Nursery Center. Trees in the spacing of 4x8 m plot were outgrown in both dbh and height. Litterfall ranged from 83 to 385 g/m2/year, it peaked in winter. Stem, leave and total above-ground biomass were greatest in the spacing of 1x1 m plot (53, 4 and 61 t/ha, respectively), while the 4x4 m spacing plot got the greatest branch biomass (3.3 t/ha). Net primary productivity ranged from 11 to 17 t/ha/year.
