The present investigation on biomass productivity, carbon sequestration among different age group of Melia dubia with respect to its growth parameters and its impact on soil properties was conducted at farmers field in Bidar District. Among the different age group the highest above ground biomass (23.64 t/ha) and carbon sequestration (13.40 t/ha) was recorded under age group of 5-7 years old plantation with spacing 3×3 m. The present investigation of bund planted Melia dubia at 3m apart also revealed above ground biomass (1.62 t/ha) and carbon sequestration (1.01 t/ha) which were on par with agroforestry system under same age group of 2-3 years old Plantation. The investigation on productivity of Melia dubia of 3-5 years old under different spacing shows maximum above ground biomass (26.04 t/ha) and carbon sequestration ((14.7 t/ha) under the spacing of 4×4 m. The influence of Melia dubia Plantations of different age group on soil properties showed higher soil pH (7.60) and Available Nitrogen (276 kg/ha) under age group of 1-2 years old plantation. It also showed maximum EC (0.23), Available Phosphorus (64.40 kg/ha), Available Potassium (388 kg/ha), Organic Carbon content (0.77 %) under age group of 5-7 years in plantation as compared to control (without trees) respectively. Therefore study revealed findings are useful in the field of environmental science.EnglishASSESSMENT OF BIOMASS PRODUCTIVITY OF Melia dubia IN BIDAR DISTRICT, KARNATAKAThesis
