EFFECT OF GROWING MEDIA AND BENZYL AMINO PURINE ON MACROPROPAGATION OF BANANA CV. ‘MALBHOG’

Abstract

An Experiment was conducted at Horticulture Centre, Department of Agricultural Extension (DAE) , Burirhat , Rangpur during the period of February 2020 to May 2020 to investigate the macro propagation of banana cv.‘Malbhog’ as influenced by different growing media and Benzyl Amino Purine in different concentrations . The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Treatments were different media viz, Mo: Control (Soil), M 1 : Rice husk, M 2 : Saw dust, M 3 : Cocodust and four levels of BAP, viz, So: Control (0ml/L), S 1 : 20mg/L, S 2 : 30mg/L, and S 3 : 40mg/L concentrations. Results indicated that days of first sucker emergence and highest values of vegetative growth i.e; number of suckers, suckers height, number of leaves, sucker collar diameter (cm), number of roots and roots length attributed the highest ramifications for the treatment of M 3 (Cocodust) and S 3 (40 mg/L) of BAP. Combined applications M 3 S 3 produced the best result for first time sucker emergence, number of sucker, sucker height and other vegetative growth and development. So, it can be concluded that cocodust media with 40 mg/L concentrations of BAP treatment combination is suitable for better macro propagation of banana cv.‘Malbhog’.
