Abstract
A field experiment was conducted to study the influence of bunch cover on yield and quality of banana cv Ney Poovan (AB) under high density planting system in hill zone of Karnataka during 2020-21 at famer's field, Kittlegandi village, Mudigere taluk. Experiment was laid out in Randomized Complete Block Design comprising of eight treatments with three replications. Among the different treatments studied, the treatment blue non-woven polypropylene bunch cover (17 GSM 100% UV stabilized) recorded maximum bunch weight (11.05 kg), bunch width (35.01 cm), bunch length (60.13 cm), number of hands per bunch (11.58), number of fingers per bunch (162.14), finger weight (69.12 g), finger girth (37.68 mm), finger length (12.28 cm), hand weight (1.11 kg), number of fingers in second hand (15.48) and yield per hectare (36.82 t). The same treatment recorded minimum number of days taken from shooting to harvest (115.94). Behavioural parameters such as maximum green life (5.10 days), shelf life (9.20 days), minimum physiological loss in weight (8.20 %). Fruit quality parameters viz., TSS (27.37 °B), total sugars (20.50%), reducing sugars (17.17%) and non-reducing sugars (3.33%) were recorded maximum in bunch covered with blue non-woven polypropylene (17 GSM 100 % UV stabilized) bag. There were no incidence of thrips and anthracnose observed and also maximum B:C ratio (2.43 :1) was obtained in the same treatment. Hence, the treatment blue non-woven polypropylene bunch cover (17 GSM 100% UV stabilized) proved to increase yield, quality and reduce the incidence of pests and diseases in banana cv. Ney Poovan under high density planting system. Further, the treatment white non-woven polypropylene bunch cover (17 GSM 100% UV stabilized) also recorded on par results with the above treatment with respect to yield, quality and in reducing the pest and diseases in banana.
