Abstract
Bio-hardening is a process where micro propagated plantlets are inoculated with suitable strains of microorganisms in order to enhance their acclimatization. Trials were taken to expose banana plantlets to useful microbes that encourage growth and mutual association during 2022 at UHS, Bagalkot. It promotes host plant growth, plant nutrient uptake, inhibits pathogen growth, reduces disease severity, enhances tolerance to environmental stress etc. In the present study, twenty treatments were imposed with different bioinoculants by two methods of application (1) powder formulation and (2) liquid formulation. Among these treatments, M1T13- VAM and fusicont significantly increased the survivability per cent (58.80%), plant height (6.46 cm), pseudo stem girth (5.42 cm), number of leaves (4.07) and leaf area (33.15 cm2). Thus, the artificial inoculation of bioinoculants through the powder formulation enhances the growth during primary hardening.
