| dc.description.abstract | The present study entitled “Appraisal of different agroforestry systems for biomass production and carbon stock potential in Karsog valley of District Mandi in Himachal Pradesh” was conducted during 2022-2023 in the Department of Silviculture and Agroforestry, College of Forestry, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh. For the present study, Karsog valley was divided into three different elevations i.e. <1000 m, 1000- 1500 m, >1500 m, to identify dominant agroforestry systems, for their biomass production, carbon stock and soil properties. Agroforestry systems prevalent in the study area were agrisilviculture, agrihorticulture, agrihortisilviculture, agrisilvipastoral, silvipastoral. The results of the present investigation revealed that different land use systems have significant influence on biomass production and carbon stocks. The total higher biomass production was recorded under silvipastoral system at elevation above 1500 m, while the lowest total biomass production was recorded under agrihorticulture at elevation below 1000 m. Biomass and carbon stock in vegetation was maximum under silvipastoral systems at elevation above 1500 m and minimum was found under agrihorticulture system at elevation below 1000 m. Soil pH was found maximum under agrihortisilviculture system among two soil depths. EC and SOC was found maximum under silvipastoral system among different depths. Available Nitrogen was recorded maximum under agrihortisilviculture system (362.32 kg/ha) at 0-20 cm and (341.48 kg/ha) at 20-40 cm depth of soil. Available Phosphorus was noted maximum under agrihortisilviculture system (58.27 kg/ha) at 0-20 cm and (57.09 kg/ha) at 20-40 cm depth of soil.

Available Potassium was recorded maximum under agrihortisilviculture system (205.44 kg/ha) at 0-20 cm and (201.67 kg/ha) at 20-40 cm depth of soil. Bulk density was recorded maximum under agrisilviculture system (1.15 g cm-3) at 0-20 cm and (1.18 g cm-3) at 20-40 cm soil depth. Soil physical and chemical properties were found suitable for almost all type of agricultural crops. From the study, it is concluded that agroforestry systems, particularly agrihortisilviculture and silvipasture are playing an important role in soil enrichment, biomass and carbon storage in Karsog valley of District Mandi in Himachal Pradesh. Hence these systems need to be promoted further for sustainability and environmental security.ximum under agrihortisilviculture system (205.44 kg/ha) at 0-20 cm and (201.67 kg/ha) at 20-40 cm depth of soil.
