In order to increase the productivity through clonal route, the Institute has established Vegetative Multiplication Gardens (VMG’s) of Casuarina (2.2 Ha), Eucalyptus (7.3 Ha), Teak (4 Ha), Tamarind (0.5 Ha), Emblica (0.3 Ha) in collaboration with State Forest Department of Tamil Nadu Kerala, Andaman & Nicobar Islands and Pondicherry. In these VMG’s, 216 CPTs of Casuarina, 351 CPTs of Eucalyptus, 129 CPTs of Teak, 59 CPTs of Tamarind and 11 CPTs of Emblica were assembled.
Successfully developed and demonstrated afforestation techniques of Quartz sand, Limestone, Magnesite and Bauxite mine dumps, using soil amendments and biofertilizers, as well as for the utilization of flyash produced in thermal power stations.
Techniques to improve the quality of planting stock were developed and using these techniques, 6 lac seedlings and vegetative propagules were produced and supplied for various tree improvement activities of the Institute as well as for the various user groups.
Training programmes on improved nursery practices were developed and imparted to the various user groups ranging from farmers to forestry students to serving officers of Indian Forest Service.
Developed and economic productivity worked for three agroforestry systems viz. 1).Agri-silviculture. (Casuarina-maize model), 2). Agri-silvi-horticulture(Casuarina-moringa-maize model)and 3). Silvipasture(Acacia auriculiformis - Pennisetumpurpureum).
Investigated Productivity and Nutrient Dynamics pattern in Teak plantations of Tamil Nadu. Similar studies were also carried out in Teak and Casuarina based agroforestry systems.
Demonstrated agroforestry practices via various extension strategies and planted about one-lakh seedling/planting stocks of forest and horticultural species under agroforestry systems in farmers field.
Evaluated seven tree species for rehabilitating degraded lands and developed Acacia planifronsbased eco-restoration model for degraded forests in Western Ghats of Tamil Nadu to meet ecological and social needs.
