The cultivation of fruits and vegetables is known as Horticulture. Agriculture is the mainstay of the people of Arunachal Pradesh and horticulture is one of the significant opportunities for their economic development. West Kameng District is one of the important producers of horticultural crops, because of its suitable climatic conditions for some specific crops. There is a vast scope for growing crops like -Apple, Pears, Plum, Pine-apple, Orange, Grapes, Kiwi and Vegetables like-Cabbage, Cauliflower, Beans, Tomato, Radish, Beans, Chilies, Ginger, etc. But in recent years due to increase in population causing rapid changes in climatic conditions has put an alarming sign in the development of the horticulture in the district. Climatic changes in the district is taking place due to increasing demands of the population in the form of mass deforestation, construction of buildings, increase in temperature, rainfall variability, etc. Consequently, the production rate of horticultural crops has declined in the recent decades. A comprehensive survey and personal interview / observation of the area reveal that the changes in climatic conditions have caused deep impacts on the essential growth conditions of horticultural crops in the area. Therefore, the sustainability of horticultural activities in the district has been threatened to a greater extent, which needs immediate controlling measures.

Phytogeography is a branch of biogeography w hich deals w ith geographical distribution of plant species in different env ironments. It giv es details about the different v ulnerable and endangered plant species. It gains emphasis in concern to the present env ironmental degradation and global climatic extremeness caused by man-induced problems in the form of large scale catastrophes and global w arming. The study area i.e. Low er Dibang Valley is one of the richest biodiv ersity hotspots in Arunachal Pradesh. The Adi tri bes w ho inhabit the area are dependent on the forest resources for their liv elihood. The study finds that most of the economic, social and cultural activ ities of the people are dependent on the av ailable forest resources. They are still dependent on the forests though influences of scientific and technological dev elopment are emerging in the area. The study rev ealed that the forest cov er is rapidly depleted due to ov erexploitation for material culture and agricultural extension. The plants like Terminalia myriocarpa, Duabanga grandiflora, Phoebe spp., Oroxylum indicum, Clerodendrum colebrookianum, Zanthoxylum rhetsa, etc. are ov erexploited and threatened. Therefore, emphasis has to be giv en on the conserv ation of endangered species like ethno-medicinal plants and application of traditional know ledge system in harnessing the v alued plant species.

Its documentation is very important in present context of higher side effects of synthetic drugs; while traditional or indigenous herbal therapy is time tested with little side-effects. It is more relevant in case of Arunachal Pradesh where various tribes have rich traditional knowledge passed down orally through generations. This communication brings ethno-medicines practised by Aka tribe of Arunachal Pradesh. A total of 18 plant species and their uses in curing ailments is reported in this study.

Taxol produce from the barks and leaves of the Taxus plant has anti-cancer properties with high pharmaceutical demand worldwide. Taxus has been reported to be found in the different parts of Arunachal Pradesh. However, large scale supply and illegal trade occur in Arunachal Pradesh especially during 1990s. This paper aims to explore the present status, impact of trade and natural regeneration of Taxus plant in West Kameng District of Arunachal Pradesh. Interactions with villagers disclose that Taxus in pure stands is no more available in the nearby vicinities. The random transacts in the forest areas reveals many dead plants in different areas of the district. Out of the 143 plants located by the 105 are dead trees, only 4 are live trees, 14 are saplings and 20 are newly growing seedlings.

Arunachal Pradesh has started to promote floriculture, especially orchids for export oriented cut-flower industries. The diverse agro-climatic condition provides an ideal opportunity for growth of agro-based industries. Floriculture is one of such industry having great potential in the state. In this paper an attempt has been made to analyze the problems and prospects of floriculture in Arunachal Pradesh with a focus on orchids. A comprehensive survey and interview was conducted for the existing orchid research and development centers to derive suitable conclusions. The study reveals about 550 species of orchids in the state, out of which about 100 species are ornamental belonging to genera Aerides, Ascocentrum, Calanthe, Cymbidium, Dendrobium, Epidendrum, Paphiopedilum Phaius, Renanthera, Rhynchostylis, Vanda, etc. So far five hybrid genus -Renades "Arunodaya" Arachnocentron "Tipi Jubilee star", Esmeranda "Millennium Dawn", Cymbidium Sessa "Green Beauty" and Ascocenda "Tipi Blue Boy" were successfully introduced in the state.

These people in rural villages are still more or less dependent on herbal medicines in this age of modernization also for overcoming various diseases. A field survey was conducted in the year 2010 and 2011 using field schedules and interview was taken from randomly selected 35 respondents who are practicing ethnomedicinal treatments. An informant consensus factor (FIC) was derived to determine the homogeneity of respondent's knowledge on various reported ethnomedicinal plants. The study revealed 26 plant species belonging to 18 families used for treating various human ailments. The most common medicinal plants belong to shrubs (46%) followed by trees (35%) and herbs (19%). In most of the cases the leaves are used as medicines. However, roots, barks, stems and sometimes the whole parts of plants are also used as ethnomedicines. The respondents have good knowledge of the medicinal plants as revealed by the consensus analysis. The abundance of forest resources plays significant role in evolving traditional knowledge of herbal medicine among the Adi people to cure and prevent diseases. Hence, the enthnomedicinal plants play a crucial role in the traditional health care system of Adi community of the area.

The efficiency of AM fungi as bio-control agents in commercial organic agriculture is gaining significance in recent decades. However, little information is available regarding beneficial role of AM symbiosis in organic manure amended soil. In the present work, an attempt has been made to study the growth performance of Chili (Capsicum frutescens L.) inoculated with AM fungi in soil amended with different dosages of organic manure. The experiment was conducted in a randomized design with four levels of organic manure (0, 50, 100 and 150%) and inoculation with five different AM Fungi species (Acaulospora denticulata, Gigaspora albida, Glomus geosporum, Scutellospora corolloidea and Scutellospora scutata). Plants were harvested after 3 months from the date of planting and plant growth was recorded. The inoculation with AM fungi at different levels of organic manure showed significantly more shoot and root dry weight than the non-mycorrhizal plants. The nitrogen content in shoot showed mixed response, resulting into significantly more nitrogen in G. geosporum, S. corolloidea and S. scutata inoculated plants in comparison to the non-mycorrhizal plants as well as plants inoculated with A. denticulata and G. albida. The Phosphorus content in the shoot was highest at 150% of organic manure application with AM plants recording significantly more phosphorus content than the non-mycorrhizal plants. Percent root infection by all AM fungi increased significantly due to amendment of soil with organic manure. Maximum root infection was caused at 100% of organic manure application in soil.

In some cases these systems date back virtually to when man started paddy cultivation. These systems generally involve some form of on-farm waste recycling technique or multiple usage of resources that enhance production capacity, helping to improve farmer's socio-economic conditions and often benefi ting the ecology as well. Integrated paddy-fi sh systems can aid intensive production of rice and fi sh protein with greater effi ciency than they can be grown in isolation, as the by-products of one system component becomes the input for other 1 .

The synthesis of thematic layers results different terrain units or land suitability class which is important for planning, land-use and land management. This paper attempts to carry out terrain analysis and land suitability classification of the Igo River basin, West Siang District, Arunachal Pradesh (India). The terrain characteristics are generated into physical, morphological, hydrological and other remote sensing based thematic layers. The Spatial Multi-Criteria Evaluation (SMCE) module is used to standardize and weigh the data. The final output, a composite index map, is sliced into three suitability categories as highly suitable (S1), moderately suitable (S2) and marginally suitable (S3). S1 and S2 occupy 96.50 km 2 (31.45%) and 56.34 km 2 (18.36%) area respectively while S3 constitutes 154 km 2 area forming 50.19% of the study area. The terrain characterization based land suitability classification using remote sensing, Geographical Information System (GIS) and SMCE is very significant in the mountainous and inaccessible area like Arunachal Pradesh.

However, the tribal people who are regarded as in the primitive stage and experiencing slow pace of development have a high degree of dependence on the natural resources for their livelihood. Bio -resources consist of all biotic components of environment, which have utility and function in satisfying the individual wants as well as social wants of man. Recently, the importance of the study on man and nature relationship has gained momentum globally and has emerged as main concern for both the developed and developing nations worldwide. As such, the tribal dominated areas by virtue of having the higher percentage of forest cover have become prime area for research in the world context for sustainable use of bio-resources.

It is found in the world's temperate forests and in Asia it occurs from Afghanistan through Himalayas to the Philippines. Owing to over exploitation, this species is disappearing rapidly. The present study in West Kameng district of Arunachal Pradesh, where maximum occurrences were reported, reveals that merciless and mass exploitation has converted the area into a 'death valley' of Taxus trees. Out of the 145 total plants located, 105 were dead trees. Efforts from stakeholders are essential for conservation and regeneration.
