Abstract:
A field study was conducted during 2018-19 and 2019-20 on “Growth and yield dynamics of jamun cv. AJG-85 under varied pruning, nitrogen and potassium levels in high density planting system” at KRC college of Horticulture, Arabhavi, Gokak, Karnataka. The research results revealed that the values for stem girth (12.48 cm), plant spread east-west (4.27 m), plant spread north-south (4.48 m) were found highest in T3 (topping at 3.5 m height) after 9 months after pruning. The maximum values for plant height (4.57 m), stem girth (11.17 cm), plant spread north-south (4.24 m) and plant spread east-west (4.14 m) was recorded in L1 (20 per cent of annual extension growth) plants. Significantly highest plant height (5.61 m), north south canopy spread (4.59 m) and east west canopy spread (4.49 m) were recorded in T4L1 (No pruning and 20 per cent of annual extension growth) treatment. Significantly highest total number of fruits per plant (518.28), highest fruit yield (6.20 kg/plant), highest yield per hectare (6.89 t) were recorded in T4 (No topping). Significantly highest number of flowers per branch (402.47), total number of fruits per plant (557.65), fruit yield per plant (6.55 kg) and fruit yield per hectare (7.28 t) was recorded in L4 (No pruning). Highest number of fruits per plant (702.72), highest fruit yield (8.17 kg/plant and 9.07 t/ha) in T4L4 were recorded in interaction effects.
