Unless you are growing it in the ground in a place with year-round growing conditions, it will be difficult to get it to flower (this is because bananas are tropical plants, and the further you take them beyond the tropics, the harder it will be to grow them).

Since bananas only generally make either female or male flowers at any one time during flowering, you will need multiple plants flowering at the same time, but at different stages in order to have pollen ready to go. M. nagensium is a rather tall plant, so physically getting up there (could be about 20ft or so) to hand pollinate can be a challenge, given that you can even get these plants to grow large and flower. Sometimes, depending on the species and where it is growing, seeded bananas can be pollinated by a non-natural (out of its native habitat) pollinator, but it is anyone's guess of whether or not this could happen wherever you are growing them, and of course this still assumes you can get multiple plants to flower at the same time.

If you manage to accomplish all of that, when you get fruit, it will not be anywhere near good eating quality, if palatable at all ( I have not had M. nagensium fruit so cannot comment on it). If you want to get fruit, just try growing edible bananas.
