The experiments was laid out in Two-factors Completely Randomized Design (CRD) with eight different types of treatment viz., T1 (Sawdust), T2 (Sawdust + Azotobacter), T3 (Sawdust + Trichoderma), T4 (Sawdust + Azotobacter + Trichoderma), T5 (Sawdust (50%) + Banana fibre waste (50%) + Azotobacter), T6 (Sawdust (50%) + Banana fibre waste (50%) + Trichoderma), T7 (Sawdust (50%) + Cocopeat (50%) + Azotobacter), T8 (Sawdust (50%) + Cocopeat (50%) + Trichoderma) which were replicated five times. The results of the investigation that, among the different growing media of T6 (Sawdust (50%) + Banana fibre waste (50%) + Trichoderma) gave better performance in macro-propagation of banana on growth parameters. With referce to different propagation media, Sawdust (50%) mixed with Banana fibre waste (50%) & Trichoderma recorded maximum survival percentage (94.79 %), minimum days taken primary bud (21.45), secondary bud (46.91) & tertiary bud emergence (58.99), and maximum number of primary shoots (4.21), secondary shoots (7.16) & tertiary shoots (19.91). Same growing media also recorded minimum days taken for root emergence (17.61 days), maximum number of roots per shoot (161.10), primary roots (24.89), secondary roots (46.32), tertiary roots (89.90) & highest root length (21.88 cm).EnglishThesis
