Abstract:
The experiment was conducted to study the effectiveness of banana macro-propagation using three methods of corm preparation; whole corm, ½ split corms and ¼ split corms in five types of media; soil, sand, cocopeat, soil + sand and sawdust. Were laid out in a 2-factor factorial completely randomized design. Various parameters were studied and data were analyzed at 5% level of significance. The result were reveal that least number of days was recorded in sand 21.0 days, sawdust 22.00 days, and soil 22.40 days as compared to soil + sand 23.70 days and cocopeat 29.80 days. Highest number of plantlets was generated from ¼ split corms (29.49), followed by ½ split corms (27.84) and whole corm (25.24). The quality parameters of plantlets with respect to highest plant vigour was obtained from the whole corm followed by those obtained from ½ split corms and ¼ split corms while whole corm and ½ split corms were more vigorous plantlet when planted in sawdust, sand and cocopeat. From the results of the current study, it could be recommended to use ½ split corms as propagules, which met both higher number as well as quality of planting materials. Further, sawdust, sand and cocopeat can be recommended in that order of priority depending on availability in a particular area.
