During the period 2004-2016, a field experiment was conducted at the All India Organized Research Project on Palms, Regional Coconut Research Station, Bhatye (DBSKKV, Dapoli), Maharashtra, (India) to evaluate the carbon sequestration and productivity potential of twelve coconut hybrids and three varieties laid out with three replications in a randomised block configuration. The findings showed that the two hybrids, GBGD x ECT (127.6 nuts/palm/year) and COD x LCT (108.0 nuts/palm/year) were superior in terms of nut production, followed by WCT x MYD (107.6 nuts), ECT x GBGD (106.9 nuts) and 'Pratap' as standard. In addition, the coconut orchard contributed significantly to the improvement of the above and below ground carbon stock. In the East Coast Tall variety (312 kg/plant and 27.32 t/ha respectively), the above ground biomass and carbon stock registered was the largest, followed by the hybrid WCT x GBGD (308.69 kg/plant and 27.01 t/ha respectively) and the lowest was in the hybrid MYD x ECT (138.71 kg/plant and 12.14 t/ha respectively). In the hybrid ECT x MYD rhizosphere, the highest soil carbon stock of 39.12 t/ha and 37.16 t/ha at 0-30 and 31-60 cm depth was reported and the lowest soil carbon stock (35.52 t/ha and 34.71 t/ha) was observed in the hybrid PHOT x GBGD.
