IMPACT OF TREE AGE ON BIOMASS GROWTH AND CARBON ACCUMULATION CAPACITY OF AGROFORESTRY SYSTEMYogesh Kumar, Anita Thakur and Tarun Kumar Thakur
The biomass and carbon storage was assessed during 2017-2019 in a well-established agroforestry experiment on Dalbergia sissoo and Emblica officinalis based agroforestry system at the experimental field of Krishi Vigyan Kendra, Indira Gandhi National Tribal University, Amarkantak, Madhya Pradesh. The study was conducted ina 4 year old tree vegetation based agroforestry system.Result revealed that the biomass was increased from 6.3%, 8.6%, 16%, 7.7% and 8.6%, respectively in treatments viz; T1, T2, T3, T4 and T5 as tree age increased from 3 years to 4 years. However, highest biomass was observed in treatment T1 (24.48 Mg ha-1 yr-1). The trend of carbon sequestration potential (CSP) of land used system to show the percent change was highest in T3 (16%) and lowest was observed in T1 (6.3%), respectively. Meanwhile, highest CSP of the system was observed in pure Dalbergia sissoo (T1) base treatment (44.8Mg ha-1 yr-1).
