Abstract

The study on the growth and carbon storage of the seven years old Hevea brasiliensisplantation in Bebeka coffee farm was undertaken and analyzed through stratifiedrandomized block design with sub-sampling analysis of variances. Four randomizedstands per planting distance per block were taken as sample plots. The measured datawere diameter at breast height (1.3m above the ground); total tree height; merchantableheight has taken from field, while carbon density was calculated as = biomass density x45%. The 2m x 4m dominated with a mean of 13.05 ± 0.3cm followed by 2m x 3mplanting distance and the least is 2m x 2m diameter. The result of the study shows thatthe planting distance influences the diameter at breast height. The 2m x 4m weredominated with mean heights of 9.84 ± 3.13m and 5.9 ± 1.32m, respectively followed by2m x 2m and the least is the 2m x 3m. The 2mx4m dominated in C density with a meanof 52.13 ± 8.71Mg ha -1 followed by 2m x 3m and the least is 2m x 2m implying thatabove ground biomass of the plantation is affected by planting distance. The 2m x 4mspaced plantation is significantly different from other spacings while the result of 2m x3m and 2m x 2m spacing is not significant for both C and biomass density. C density ispositively related to all growth traits of Hevea brasiliensis, which indicates is a good Csink bases on the finding of the present study.
