An experiment was conducted at Mundgod located at 140 58' N Latitude, 750, 06' E Longitude and at altitude of 563.9 m in hill zone of Karnataka, India, during the year 2001-2002. Teak plantations raised with high input management practices viz., application of fertilizers (organic and chemical), irrigation, weed management and intercultural operations for 2 years after planting were selected as better managed plantations. Plantations raised without any management practices were selected as poorly managed plantations. Observations viz., plant height, diameter at breast height and wood density were recorded in five year and ten year old plantations. Results indicated that plantations raised with high input management practices recorded 19.471 and 59.552 tonnes wood biomass per hectare in five and ten year teak plantations as compared to only 8.866 and 31.517 tonnes in poorly managed plantations respectively. Carbon sequestration in five and ten-year-old plantations due to management practices was 4.879 and 12.896 tonnes higher per hectare respectively when compared to poorly managed teak plantations. On an average 0.976 and 2.579 tonnes of excess carbon has been sequestered per hectare per year in better managed plantations over conventional grown (poorly managed) five and ten year old teak plantations respectively. The results indicated that high input management practices followed at initial years (2-3years) had increased the carbon
sequestration in five and ten year old teak plantations.
