Abstract

Tree carbon sequestration is the process by which atmospheric carbon dioxide is taken up by trees, grasses, and other plants through photosynthesis and stored as carbon in biomass (trunks, branches, foliage, and roots) and soils. Even though, the earth naturally stores carbon in forest, oceans, and soil, these carbon sinks are unable to excessive and increasing amount of carbon dioxide humans continue to emit. The experiment was carried at University of Agricultural Sciences, GKVK, Bengaluru to know optimum spacing for maximum wood volume production and higher tree carbon sequestered in teak plantation through agroforestry system. In seven years old teak plantation maximum tree height (7.93 m), girth at breast height (GBH) (52.67 cm), wood volume (15.8523 m3 ha-1), total tree biomass (45.94 t ha-1) and tree carbon sequestered (22.97 t ha-1) was recorded with a spacing of 12 m × 3 m followed by 10 m × 3 m and 8 m × 3 m. The objective of the study was to improvise the carbon sequestration along with tree pulp yield.

Conclusion

Carbon sequestration in teak plantation increases with increase in spacing and age of the tree. In seven years old teak plantation maximum tree carbon sequestered was 22.97 t ha-1. Intercrops such as cereals and pulses can be taken till seven years of plantation and then shade loving crops are preferred for economical yield.
