Abstract: The experiment was conducted at farmers field in Uttara Kannada district to study the effect of integrated nutrient management on early growth performance of agarwood. Ten treatments consist of organic, inorganic and biofertilizers combination were imposed on agarwood. The data on growth parameters revealed that, the maximum tree height and diameter was recorded in T6 (4.11m & 4.52 cm) respectively. Whereas crown diameter and number of branches were found highest in T10 (138.9 cm & 10.3) respectively, on the other hand maximum tree volume was noticed in T6 (6227.9cm3). The higher organic carbon percent was recorded in T8 (0.73%), and maximum available nitrogen was also found in T8 (383.00kg/ha), while available phosphorous and potassium were recorded highest in T9 (44.44kg/ha) and T5 (242.00kg/ha) respectively. The results clearly indicated that the treatment (T6) FYM (2 Kg/ tree) + VAM (100 g/ tree )+ PSB (50 g/tree) + Azospirillum (50 g/tree) was found best in terms of tree height, diameter and total volume of tree.
