The present investigation entitled “Studies on macropropagation in Red banana (Musa AAA)” was carried out during 2017-18 at the Department of Fruit Science, Kittur Rani Channamma College of Horticulture, Arabhavi, University of Horticultural Sciences, Bagalkot, Karnataka. Kamalapur Red banana is a geographical indicator crop and getting more popular in Karnataka. As demand for red banana planting materials is increasing, there is an urgent need for the production of low cost disease free healthy planting materials. In correspond to this problem studies were conducted to know the effect of different substrate, growth hormones and bio agents on plantlet regeneration in red banana through macro propagation. Among different substrates, potting media [soil + FYM (2:1)] (T1) showed significantly best result in terms of number of days taken for first bud emergence (24.40), number of primary buds per corm (3.40), number of plantlets after secondary decapitation (6.26) and total number of plantlets per corm (9.80). Among different growth chemicals and bio-agents treatments, potting media BAP took less number of days for first bud emergence (27 days) whereas, treatment combination of VAM + BAP + P. fluorescens + T. harzianum (T10) recorded maximum of primary buds per corm (3.93), number of plantlets after secondary decapitation (12.26), total number of plantlets per corm (15.58) and took less number of days for secondary decapitation (49.43). Root colonisation (98%) and number of chlamydospores/50 g of soil (1008) of VAM also recorded more in T10. Population of T. harzianum, P. fluorescens and A. brasiliense were recorded maximum (9×106 cfu/g, 6×106 cfu/g and 4×106 cfu/g respectively) in the treatments where these microbes are inoculated alone respectively.
