Abstract:

The fast growing native species Melia dubia is gaining momentum among the farmers for raising commercial plantations. To standardize the plant geometry, an important silvicultural package for raising Melia dubia as commercial/ agro-forestry plantation, a trial was conducted in the TNPL’s Plantation Research Block, Kagithapuram, Karur, Tamil Nadu. Melia dubia clonal plants var.GK-10 was used as test variety. The trial was conducted in monoculture block plantation system. Four spacing i.e. 1.5 m X 1.5 m (4444 plants ha-1), 2m X 2m (2500 plants ha-1), 2.0m X 2.5m (2000 plants ha-1) and 3.0m X 1.5m (2222 plants ha-1) were adopted in this study. The experiment was conducted in randomized block design and replicated four times. Bio metric observations viz. GBH, Height, stand volume, total biomass and amount of carbon sequestration was recorded at periodic interval of once in six months. The results revealed that although the individual trees performed superior in recording higher values of growth and yield attributes in wider spaced plots, closer spacing with 1.5m X 1.5m (4444 plants ha-1) and 2m X 2m (2500 plants ha-1) recorded significantly higher stand volume and yield per ha as compared to wider spacing plantations. The maximum biomass production and carbon sequestration were also recorded higher with the closer spacing plantations.
