ABSTRACT Experiment was carried out to study the growth and yield pattern of tree borne oilseed crops based agroforestry system for the Eastern dry zone of Karnataka conducted in GKVK, University of Agricultural Sciences, Bengaluru. The soil of experimental site was neutral in pH and medium in available Nitrogen, Phosphorus and Potassium. The experiment was laid out in Randomized Block Design with seven treatments and replicated thrice. The growth parameter of 11 year old TBO’s revealed that, Melia dubia recorded significantly higher tree height (12.54 m,13.22 m and 12.88, respectively), Girth at breast height (113.28 cm, 114.84 cm and 114.06cm, respectively), bole height (4.85 m, 5.13 m and 4.99 m, respectively), collar diameter (139.29 cm, 116.82 cm and 114.06 cm, respectively), Canopy spread towards N-S (14.37 m, 14.79 m and 14.58 m, repectively ) and E-W (11.83 m, 11.93 m and 11.87 m, respectively) directions and wood volume (0.389 m3, 1.8410 m3 and 1.115 m3, respectively) during 2019, 2020 and pooled respectively. It was followed by Melia azedarach, Simarouba glauca, Azadiractha indica, Madhuca latifolia, Pongamia pinnata and least growth parameters were observed with Callophyllum inophyllum. Thus, it clearly indicated that Melia dubia found to be one of the fast growing TBO’s among the seven tree borne oilseed crops. Further, higher tree carbon stock (40.93 t ha-1, 42.73 t ha-1 and 41.83 t ha-1, respectively) and soil carbon stock (29.16 t ha-1, 30.41 t ha-1 and 29.78 t ha-1, respectively) during 2019, 2020 and pooled respectively was recorded by Melia dubia based agroforestry system. |
