Growth and Nutrient Requirements in a Teak Plantation Age Series in Nigeria. I. Linear Growth and Biomass Production
Abstract:Forty trees equally distributed to represent diameter range and first 15 years of growth of quality one teak stands in Gambari Forests in Southern Nigeria were sampled and linear dimensions and the aboveground biomass accumulation and distribution measured. Height, diameter (d.b.h.), basal area (b.a.), volume, leaf area, and leaf area index (L.A.I.) increased with age during the first 15 years. Mean annual height and diameter increments decreased while those of b.a. and volume increased with stand age. Total dry matter production in 15 years was about 592 mt/ha. Biomass of stem and branch components increased while that of foliage decreased with increasing age. Diameter growth of 250 largest stems, or crop trees, stagnated at 10 years. This is proposed as time for first thinning in such stands. Equations relating mean tree biomass to d.b.h. are presented. Forest Sci. 29:159-165.
