Abstract
The study entitled “Studies on teak (Teactona grandis linn. f.) based agroforestry system” was carried out from October 2020 to May 2021 at agroforestry unit, ZARS, GKVK Bengaluru. The study involved quantification of litterfall, litter decomposition, carbon sequestration and to know the influence of Teak on growth and yield of intercrop. Litter production over the months varied significantly throughout the study period. The accumulated litterfall during the study period in T1 (12 m × 3 m), T2 (10 m × 3 m) and T3
(8 m × 3 m)was 394.66 Kg/ha,562.51Kg/ha and 837.05 Kg/ha respectively and the averagedecomposition rate constant of Teak was found to be 0.235 k month-1. In addition to this
carbon sequestration potential of Teak in T3 was observed as 164.6 t/ha. Growth parameters like plant height, number of leaves and number of branches was found to be more for agricultural crop which was grown as main crop when compared with intercrop with Teak. Growth parameters of teak like height and girth was seen higher in the T1(12 m × 3 m)i.e., 8.70 m and 0.47 m respectively.
