Spacing Effects on the Growth and Carbon Storage of Plantation-grown Trees in the Njala University Tree- Spacing Experimental Plots, Southern Sierra Leone | Chapter 8 | Emerging Issues in Agricultural Sciences Vol. 1

 This study distinguished the tumor and element storage of Tectona grandis, Gmelina arborea, and Terminalia ivorensis cultivated at four various structure in the five-old age-old organize trial plots at Njala University; Southern Province, Sierra Leone. The structure selected were 1.8 m x 1.8 m, 2 m x 2 m, 3 m x 3 m, and 4 m x 4 m. The study determined the effects of these structure on shrub progress limits and element storage in the same-ground sapling biomass. The variety were cultivated in square plots consisting of four various structure. Data was composed on sapling height, width at feelings crest, and crown breadth. The dossier were subjected to reasoning of difference (ANOVA) to decide meaningful differences in sapling tumor and element depository under different organize levels at P < 0.05. Results disclosed that organize had a statistically meaningful effect on basic area per hectare (P = 0.001) and crown breadth (P = 0.001), accompanying the irregularities of total forest height (P = 0.354), width at conscience crest (P = 0.234), stand book (P = 0.131), biomass (P = 0.114) and biomass carbon (P = 0.114). The results imitated the 1.8 m x 1.8 m organize to introduction conditions of total forest height (3.4 m) and basic region per hectare (2.15 m2 ha-1). The 2 m x 2 m present highest in rank results for diameter at bosom altitude (9.18 cm) and stand book accrual (5.29 m3 ha-1), while biomass (26.4 kg) and biomass carbon (11.86 kg C) were topmost in the 3 m x 3 m organize. The most expansive organize 4 m x 4 m ruled in terms of crown breadth increase (4.776 m). The results imply the choice of organize as a key determinant in carrying out the destined administration aims of plantation institution.
