The investigation entitled “Standardization of suitable treatment for sucker production of Malbhog (AAB) banana through macropropagation” was carried out at Instructional cum Research Farm, Department of Horticulture, Biswanath College of Agriculture, Assam Agricultural University, Biswanath Chariali with a view to standardize the best treatment combination suitable for production of suckers of Malbhg (AAB) banana through micropropagation. Ten Treatments were T1 (Control), T2 (Trichoderma viride), T3 (30 g BAP + 30 g Trichoderma viride), T4 (0.04 % BAP), T5 (0.04 % BAP+30 g Enriched Compost), T6 (30 g Trichoderma viride + 0.04 % BAP + 30g Enriched Compost), T7 (200 g Azospirillum and 200 g PSB in 10 kg of vermicompost), T8 (50 ppm GA3), T9 (0.25 % IBA) and T10 (100 g Nitrogen/plant). Treatment combinations replicated thrice following Randomized Block Design. Result of the investigation revealed that the corms treated with BAP with Trichoderma viride (T3) produced the highest number of primary (3.07), secondary (5.73), tertiary suckers (18.94) followed by 2.94, 4.82, 18.40 in T4 (BAP), respectively. BAP (T4) recorded the shortest pseudostem (17.17 cm), highest number (5.87) of the functional leaves, the broadest leaf (17.18 cm), highest number of primary roots (24.72) and longest roots (46.56 cm). The highest benefit: cost ratio of 2.64 was obtained in T4. Among the treatments, T4 (BAP @ 0.04 %) and T3 (BAP @ 0.04 % + Trichoderma viride @ 30 g have shown good results with higher number of suckers and higher percentage of regeneration.
