Effect of bunch feeding and bunch spraying on vegetative and yield parameters of tissue culture banana CV. Ney Poovan

Abstract

The field experiment was conducted during 2017-2018 at College of Horticulture, Mudigere with an objective to know the effect of bunch feeding and bunch spraying on vegetative and yield parameters of tissue culture banana cv. Ney Poovan under hill zone of Karnataka. The banana bunch stalk was fed with different nutrients like urea, sulphate of potash, banana special and organic formulations like panchagavya and Amrutpani. The bunch spraying was done with growth regulator 2,4-D at 30 ppm and compared with control (without bunch feeding and bunch spraying). The results revealed that bunches fed with urea (7.5g)+ SOP(7.5g) along with bunch spraying with 2,4, -D 30 ppm recorded significantly higher bunch length (73.71 cm), internodal length between hands (5.80 cm) finger length (14.92cm), finger girth(38.86mm),finger circumference (12.94 cm), finger weight (88.60g), hand weight(1.36Kg), bunch weight (15.63Kg)and total yield per acre (15.63 t/ha) and total yield per hectare (39.08 t/ha) with a highest benefit cost ratio (3.56) as compare to control.
