Abstract:
The present research experiment was studied at Regional Fruit Research Station, Ganeshkhind, Pune and Division of Soil Science and Agricultural Chemistry, College of Agriculture, Pune during 2020-2021. An 18-year-old Sapota orchard that had been planted on Inceptisol was used for the experiment. Eight alternate bearing Sapota genotypes were delineated for research along with traditionally cultivated soil. Biometric observations recorded during the study viz. diameter at breast height, tree height, volume of tree, below ground biomass, above ground biomass, total plant biomass and plant carbon were taken uniformly for the estimation of carbon stock from Sapota genotypes. Estimates were made for the soil organic carbon stock at two depths and carbon sequestration per tree during an 18-year period. Among the Sapota 8 genotypes, CO-2 recorded higher tree height (540 cm), diameter at breast height (57 cm), volume of tree (1377251.10 cm³), above ground biomass (1115.57 kg tree^-1), below ground biomass (290.04 kg tree^-1) and total plant biomass (1405.62 kg tree^-1) which resulted into higher accumulation of plant carbon (702.81 kg tree^-1) followed by PKM-1 and PKM-Hy-7/1. Significantly higher soil organic carbon stock was recorded from CO-2 (36.94 and 35.64 Mg ha^-1) followed by PKM-1 (36.70, 35.08 Mg ha^-1) while lower soil organic carbon stock was observed in Cricket ball (32.56 and 31.46 Mg ha^-1).
