An experiment was conducted at farmer field to determine the effect of different bunch stalk feeding with different growth regulators on yield of banana cv. Robusta (AAA-group) under hill zone of Karnataka. The experiment was laid in RCBD with 16 treatments and three replications. Urea (2.0, 4.0 and 6.0 %), sulphate of potash (1.5, 2.0 and 2.5 %), 2, 4-D (10, 20 and 30 ppm), panchagavya (2.0, 4.0 and 6.0 %) and banana special (0.2, 0.4 and 0.6 %) and compared with control (without bunch stalk feeding). Results revealed that, at the time of harvest, bunch fed with 2 per cent sulphate of potash recorded significantly yield characters such has highest intermodal length (8.93 cm), bunch length (85.20 cm), finger girth (12.79 cm), finger weight (170.10 g),weight of hands (2.60 kg), weight of bunch (24.21 kg), total yield (60.53 t/ha) and benefit cost ratio (2.68). Significant results on quality characters observed in bunch fed with 2.5 per cent sulphate of potash recorded significantly lowest physiological loss in weight (10.44 %), more days to ripe (14.33 days) under ambient condition, longer shelf life (8.67 days), highest total sugars (18.49 %), less titratable acidity (0.25 %), highest Sugar : acid ratio (73.14), reducing sugar (15.86 %) and non reducing sugar (2.63 %) compared to control (13.20 %, 10.67 days, 6.67 days, 15.21 %, 0.33 %, 45.62, 13.01 % and 2.20 % respectively). Bunches fed with 2.0 per cent sulphate of potash recorded significantly highest pulp weight (109.16 g), peel weight (42.31 g), pulp to peel ratio (2.58) and TSS (23.51 0Brix) compared to control (90.81 g, 38.00 g, 2.39 and 19.88 0Brix respectively).
