A total of seven wild Musa spp. namely M. balbisiana, M. itinerans, M. velutina, M. markkuana, M. flaviflora, M. siangensis and one unidentified spp. named Musa M1, and three domesticated cultivars Jahaji, Sabji-kol and Chini-champa were recorded from different parts of Namsai district, Arunachal Pradesh. One unidentified species needs taxonomic characterization and description which may be a new species. M. balbisiana was found in abundance in the district which has been reported to occur in all states in Northeastern India particularly in Assam (Subbaraya, 2006). Most of the species were recorded from roadside, near agricultural fields and nearby forests. Some of the species such as the unknown Musa M1 and M. siangensis were under tremendous stress due to expansion of roads, agriculture fields and deforestation activities. Moreover, M. siangensis was recorded from East Siang district located near agriculture lands and human settlements which restricted its distribution and rare occurrence making it an endangered species (Taid et al., 2024). This suggests that urgent need for state level conservation strategy is required to conserve these species from extinction.
The highest use of Musa species was observed in Ceremonies and rituals. Rituals such as Khnpasa-mau where the bride is allowed to pass between two Musa sucker tied with rope after marriage while entering the groom house is an important ritual of the Khamti tribe. Likewise, the use of Musa species in Antrekang – ritual performed for positive spirit in a house after death of a household member, Hapsomna – a ritual done for good fortune during rice harvest, Maikho-sumphai – a ritual where the khamti tribe pray to God for warm and sunny weather by burning woods after chill winter, Nunsietapong – a conical structure resembling a temple (Kong-mu) where banana pseudo stem is used to construct it and fruits of Musa species are also offered in various ceremonies and festivals in Khamti tradition. These practices show that the Khamti tribe has preserved their traditional ways of celebrating ceremonies, functions and rituals, which are also an important part of their life. Authors such as Laishram & Thokchom 2019, Kumar et al., 2023 and Devi et al., 2024 also reported the use of Musa spp. in different ceremonies and rituals.
Traditional dishes such as Pikoi-sen, Pikoi-moh, Pikoi-tam, Pikoi-tangnam and Paa-som are an important traditional dish prepared from Musa species by the tribe. Jumari (2000) reported the use of some varieties of Musa spp. were cooked in various dishes. Paa-som which is prepared by using Pseudo stem of M. itinerens added with fermented fish is an important dish which is compulsory on several occasions such as marriage, naming of newborn baby, housewarming etc. M. balbisiana leaves also play an important role in making local pitha (Tongtep), which is prepared during festivals. Musa inflorescences are not only consumed but also sold in local markets. Padam (2014) reported that banana inflorescence is consumed as vegetables. The inflorescences of wild Musa species such as M. balbisiana, M. flaviflora, M. itinerens, M. markkuana and M. velutina were consumed as vegetables and sold in local markets for 20–50 rupees. The price ranges according to the size of the inflorescences.
Tribal people have used parts of the plant including banana traditionally as medicine to cure diverse health ailments (Dutta et al., 2019). Such traditional medicines from Musa species were also observed which is still practiced by the Khamti tribe. These includes, consuming crushed seeds of M. balbisiana after mixing with water cures piles and it acts as vitamins for infants. The sap of M. balbisiana is consumed to cure dysentery and stomach-ache. Similar study was conducted by Emery et al., (1997); Sampath et al., (2012) on the effects of Banana on curing stomach troubles and other stomach related ailments. De-worming and cough are cured if the burnt peel mixed with water of M. balbisiana is consumed. Decay pseudo stem of M. balbisiana mixed with garlic cures tooth pain. Elephant owner feeds their elephants with the pseudo stem of Musa species to get energy during work. Recently, Mehra et al., 2014, Jyothirmayi & Rao 2015, Yuhlung & Battacharyya 2016, Galini 2019, Ajijolakewu et al., 2021, Supiandi et al., 2023, Gaikwad et al., 2023 and Rahman et al., 2022 reported different traditional medicines utilized from different Musa spp.
Musa plants are also utilized in other purposes such as domestic purposes, packing, feed, manure and miscellaneous purposes. Musa leaves are used in various daily purposes such as plates in various ceremonies and festivals, steaming of fish, to store dry meat and fish, roof in forest camps, wrapping beetle leave for selling and to wrap vegetables for selling. It is also planted in areca nut plantation which serve as a nurse crop. The leaves and pseudo stem are also used as manures. The pseudo stems are used as fodder for pig. Similar reports were conducted by Aurore et al., (2009) that unpeeled green bananas are used as pig feed while Akinyele & Agbro (2007) reported the use of Musa waste as animal feed. The pseudo stem of Musa species is used in making Huttak-phai (traditional fire chulla) and local boat for rafting or crossing river. The leaves of M. balbisiana were used to write and practice Khamti scripts by monks. These practices and uses of Musa species in various purposes shows that Musa species has been an important part of human life since time immemorial. Further, scientific investigation may be done on the wild Musa species on the information acquired in this paper.
