Nonetheless, significant difference in species selection for traditional home gardens may primarily be due to altitudinal/climatic regime and also traditional beliefs and day-today requirements of the farming people. In the study, the role of three different farming communities (Nyishis, Apatanis and Kalitas) in the preservation and management of their traditional values, faith and indigenous knowledge system were studied.

We conducted an extensive survey in three districts of Arunachal Pradesh, India, namely, Kra Daadi, Lower Subansiri and Papum Pare. The study focused on the imperative of agroforestry practices in terms of socio-economy, livelihood, food security and the existing constraints hampering the development of agroforestry practices. The traditional agroforestry has replaced the old way of jhumming that registered a decline of at least 70%-80% during the last 15 years. The practice of traditional agroforestry in this region displayed several social, environmental and economic benefits leading to the growth of adoption for sustainable development.

All the plant species studied contained stomata and cystoliths, which vary in shape and size. Actinocytic stomata type was present in only one species (Ficus sp. 1). Anomocytic type in three, and paracytic in four species. Stomatal frequency calculation revealed that the highest frequency was reported in F. hispida and the lowest in F. rumphii. There is also an indication that semi-coriaceous and coriaceous glabrous leaved species of Ficus are linked to the stomatal characters. The results have shown the presence of stalks in all the cystoliths of various sizes. Different shapes such as star-shaped, bean-shaped, solitary, round, and oblong cystoliths are recorded during the study. The largest cystoliths were found in F. rumphii, where its spinous surface is quite distinct from all other species and can be rec...

There are more than one-tenth of plant species used in drugs and health products, with more than 50,000 species being used worldwide. Arunachal Pradesh alone has recorded more than 500 species of medicinal plants used by traditional herbal practitioners. These knowledge are generally passed down orally. About 70% of the herbalists are from old generation, which shows that this wisdom in the young generation is degrading fast due to rapid modernization. Unfortunately, medicinal plant resources are being harvested haphazardly in increasing volumes from its native habitat. Recently, various sets of recommendations relating to the conservation of medicinal plants have been developed, such as providing both in situ and ex situ conservation. Also, the policymaker of the state has come up with several plans with an idea of conservation of these plants, such as Herbal Garden, State CAMPA, Demonstration plot, Demonstration plot cum Nursery and MPCA (Medicinal Plants Conservation Area). The plants used in traditional medicines are potential source of therapeutics aids and have significant role in rural healthcare system all over the world. There is a vast scope for Arunachal Pradesh to emerge as a major player in the global herbal product-based medicine, owing to its rich biological resources. Therefore, it requires urgent systematic investigation using biotechnological tools to authenticate and develop new novel drugs from the rich bio-resources of the region.

The traditional rice is in serious threats from the social diversion and reduction in agricultural practices. The study was conducted to evaluate the status of the genetic resource of indigenous Rice (Oryza sativa L.) landraces and its diversity. Forty-one rice varieties were reported from diverse elevation exposures. Both univariate and multivariate statistical analysis had provided plenty of evidence on existence of polymorphism. Pearson’s correlation of traits revealed1.8 % of the trait combinations correlated strongly (r = 0.68–1.00), 2.23 % correlated weakly (r ≤ 0.35), while 5.69% correlated moderately (r = 0.36–0.67). The dendrogram obtained from Euclidian distance and UPGMA (Unweighted Pair Group Method with Arithmetic Mean), revealed three distinct clusters. The cluster analysis using the UPGMA and Euclidean distance revealed the range of genetic distance to be 10 to 75...

A large number of plants having medicinal properties and their folk uses have remained confined to the natives of this region. The tribal community of Jonai, Assam was explored to expose the indigenous herbal remedy for malaria. Sixteen antimalarial plants belonging to 13 families were reported. The analysis revealed highest fidelity level (FL) value for Ajuga integrifolia (100%) followed by Ricinus communis (94%), Alstonia scholaris (88%), Oroxylum indicum (86%) and Achyranthes aspera (82%). The percentage of respondent's knowledge (PRK) about anti-malarial plants showed Alstonia scholaris as the most commonly known antimalarial species (53%) within this region. Preference ranking (PR) unveiled eight species to be very effective against malarial parasite, which includes Allium sativum, Artemisia indica, Azadirachta indica, Carica papaya, Clerodendrum glandulosum, Ocimum tenuiflorum, Oroxylum indicum, Piper longum and Piper nigrum. All medicine preparations are made using water as the medium and are orally administered in the form of crude extract, powder, juice and decoction. Overall analysis suggested Ajuga integrifolia, Achyranthes aspera, Alstonia scholaris, Artemisia indica, Oroxylum indicum and Ricinus communis to be used for the development of novel, economical, effective and ecofriendly herbal formulations for healthcare management.

In order to test this hypothesis, field experiments were conducted to evaluate the effects of plant residues, FYM and inorganic fertilizers on soil N and P mineralization and growth of Abelmoschus esculentus Linn. A randomized complete block design consisting of nine treatments including the control was usedwith three replications each. 'Okra' was selected as the test crop. The source of N, P and K was urea (containing 45% N), superphosphate (16% P), muriate of potash (60% K). The application of full NPKand half NPK doses recorded 72 and 84 germination percentage. Nevertheless, the plots amended with half NPK and full NPK doses did not significantly (F= 0.067, ñ< 0.05) increase the growth of crop. The regression analysis of shoot and root biomass shows positive correlation in each treatments.The study revealed that NPK amended soils showed two times more fruit biomass production than the plant residue amended soils. Net N mineralization in different treatments ranged from 0.112 to 0.410 mg g -1 day -1 .N mineralization significantly varied among the plots with inorganic fertilizers having the highest mineralized N followed by residues applied soils and controls the least. On the other hand, phosphorous mineralization was higher in fertilizer amended soils. Over all, crop residue management with supplementary chemical fertilizer loading could help have better yield response under business as usual' climate scenario.

Uses of various NTFPs have shown significant progress in cultural subsistence, commercial purposes, bioprospecting and sustainable support to forest biodiversity. The present research was conducted in a protected area to document NTFPs of plant origin with their relative importance, to record information for future investigation and discovery of novelty in drug use, and to edify the local communities on sustainable forest management. Methods :The study was aimed to assess the Nontimber forest products of Behali Reserve Forest of Assam. Data was collected from 67 households belonging to two communities, the Karbi and Munda, covering almost 50% of the total households of the studied area using semi-structured questionnaires, personal interviews, group discussions and transect walks from 2017 to 2019. Results: A total of 100 plants falling under 87 genera and 56 families were reported. Urticaceae with 6 species was the most dominant family. Trees with 35% were the most dominant group, followed by shrubs (28%), climbers (22%) and herbs (15%). Out of the reported NTFPs, 51 species (51%) were edibles, 23 species (23%) had ethnomedicinal importance, and 48 species (48%) are treated as having miscellaneous uses. Use value of all the reported species ranged from 0.01 to 0.13. Zanthoxylum oxyphyllum, Hodgsonia macrocarpa, Aristolochia cathcartii and Aristolochia assamica have high UV indicating that these species are most important for the studied population. Informant consensus factor was calculated for the different ailments recorded and a total of seven species were found to have above 70% fidelity level values, showing high reliance of the forest dependent people on these species. Conclusions: The study illustrates a high diversity of NTFPs in the area as well as an intricate relation with the people residing in the fringes of the forest. Anthropogenic activities such as construction of roads, cutting of forests for jhum (shifting) cultivation, natural calamities like landslides etc., were observed to be serious threats to native biodiversity. It is recommended to provide skill development trainings and financial support for the installation of renewable and alternative energy technologies to minimize the use of forest resources in Behali Reserve Forest for better forest sustainability.

An attempt was made to study the soil characterization associated with pre-and post- burned jhum cultivation practiced by the ethnic Nocte and Tutsa tribes of Tirap district, Arunachal Pradesh. The soil samples were collected from the same location at the pre-and post-burnt fields from the various depth of soil profile A (0-20) cm, B (20-40) cm, and C (40-60) cm. The present study reveals an overall increase in porosity, temp, pH, Moisture, and bulk density because of the burning of the jhum field. In post-burned jhum fields of all the locations, there was an overall increase in the percentage of Sodium and Calcium in soil collected and a decrease in the percentage of Nitrogen, Phosphorus, and ...

In such tribal-dominated landscapes around the world, myriads of studies have emphasized the potential of homegardens as a site for local biodiversity conservation as they are known to have a huge Indigenous Knowledge System (IKS) on the use of diverse native floras. The present study was, therefore, undertaken to investigate if the native communities of the Mishmi tribe conserved native indigenous tree species in their homegardens and if they are grown then what is the future of these tree species? It was hypothesized that harbouring greater indigenous knowledge implies greater domestication of tree species in their homegardens. Altogether, 103 species of trees were reco...

Field studies were conducted following standard ethnobotanical techniques to collect information on the use of toxic and medicinal plants used by the Wancho tribe of Arunachal Pradesh. Vigna radiata was used as a plant model in this study to investigate the antiproliferative property of selected medicinal plant extracts. Green gram seedling root apical meristem cells were used to determine the inhibition of germination and slow growth. Different concentrations of plant extract (20, 50, 250 and 500 µg/ml) were treated in a test tube containing the green gram seeds (n=5) on time dependent manner. Colchicine (20 mg/ml) was used as a standard drug for the growth retardation of green gram seedlings, while the distilled water group served as negative control. Germination test of Vigna radiata L. was performed according to IS...
