Keywords: Phytosociology, Disturbance Gradient, Species Diversity, Beta Diversity, Similarity Index.
Abstract: Different phytosociological attributes of woody vegetation were analyzed along a disturbance gradient in tropical dry deciduous forest of Hastinapur along the three sites. The disturbed site were surveyed for floristic composition, similarity index, concentration of dominance, species diversity, Adversity at each stratum of woody vegetation. Maximum numbers of trees were recorded from undisturbed site (Site-3). Acacia nilotica, Tectonagrandis (tree species) were present on all the sites although in undisturbed site these species were less in number. Acacia nilotica was dominant species of Highly disturbed (Site-1) and moderately disturbed (Site-2) sites, whereas on undisturbed site (Site-3) Acacia catechu and Tectonagrandis were the dominant species. Maximum similarity was observed between site-2 and site-3 (69.2%) and minimum between Site-1 and site-2 (25%). The value of CD and H' for trees were 0.01 on Site-2 to 0.035 on site-1 and 0.oo on site-3 to 0.014 on Site-1 respectively.

Subject: Biomass Production and Carbon Sequestration of Mangium (Acacia mangium Willd.) Under Varying Plant Spacing
Keywords: Acacia mangium, Carbon Sequestration, Biomass Production.
Abstract: The study on biomass production and carbon sequestration of Acacia mangium Willd. under varying plant spacing was conducted at College of Forestry, Orissa University of Agriculture and Technology (O.U.A.T), Bhubaneswar, India during 2013 – 2014 on 10 year old experimental plantation. The study explored a 10 year old A. mangium plantation embodying ten different spacing with the objective to find out the optimum spacing of A. mangium which is a fast growing NFT and popular now a days in agroforestry and farm forestry programmes. The biomass ranged from 106.84 to 131.46 t/ha, 19.84 to 34.27 t/ha, 22.58 to 30.28 t/ha and 42.96 to 48.97 t/ha in stem, branch, leaf and root, respectively. The total biomass varied from 192.2 to 244.91 t/ha. The overall biomass production was found to be maximum under S1(2m×1m) which was at par with S2, S3, S4, S5 and S6. The minimum values were observed under S10 with a parity of values with S9 and S6. The total biomass decreased with increase in spacing. The carbon sequestration ranged from 50.75 to 62.44, 9.42 to 16.27, 10.73 to 14.38 and 20.41 to 23.23 t/ha in stem, branch, leaf and root, respectively. The total carbon sequestration varied from 91.30 to 116.33 t/ha which decreased with increase in plant spacing. S showed highest value which 1 was at par with 2, S3, S4, S5 and S6 The S6 was found as optimum spacing. because among S to S spacing, cost of production was lowest in S due 1 6 6 to less number of pit preparation, less number of planting materials and also less cost of harvesting. Further, this spacing can provide scope for intercropping as A. mangium is a suitable tree species for agroforestry. Hence, S6 i.e 4m×2m was found to be the most suitable spacing among the ten different spacing tried.

Subject: Soil Carbon Pool Under Salix alba Plantations and Adjacent Bare Soils In Temperate Regions of Kashmir
Keywords: Bulk Density, Organic Carbon, Salix Alba, Soil Carbon Sequestration.
Abstract: The present investigation was carried out under the willow plantations established by Plantation Division of State Forest Department in Anantnag, Bandipora, Baramulla and Ganderbal Districts of Kashmir valley. Two plantation blocks of willow were selected in each District The existing Soil organic carbon, bulk density and soil carbon sequestration under Salix trees at all the selected locations were determined. The mean values for bulk density obtained from the different sites exhibit a significant variation while was found non-significant during the period of investigation. Soils under the plantations at Bandipora exhibited lowest bulk density of 1.299 g cm3, while the soils at Anantnag had the maximum values of 1.360 g cm*. The maximum soil carbon density of 68.07 t ha'1 was recorded at Bandipora, followed by 67.931 ha'1 at Baramulla, 66.861 ha'1 at Ganderbal and 66.431 ha'1 at Anantnag. The results indicate that there was a significant (p<0.05) periodic (CAI) stratification in soil carbon density values recorded during the period of investigation. Maximum (4.6611 ha1] annual addition in SOC was recorded under the canopy of willow trees at Bandipora, the least yearly accretion (4.416 t ha1) was exhibited by soils developing under the canopy of this species at Anantnag. The data further envisages that SOC recorded in soil samples collected from adjacent fallow lands were far less (34-50%) as compared to those obtained under the canopy of willow plantations at all the locations.

Abstract: Measurement of growth of an individual tree forms the basis of measurement of growth/increment of forest and ultimately, management of forest. For trees showing annual rings, growth relationship i.e. growth of breast height diameter, height and volume with age require analysis of the whole stem of the tree known as 'Stem Analysis'. Growth of breast height diameter with age can be found by 'Stump Analysis' also. During this analysis, data are collected from of trees/stumps in the field and then collected data is analysed. A computer/mobile based program in which the field data can directly be entered and all computation including graph plotting will be done by computer/mobile, is always desirable for those field foresters who are involved in Mensuration exercise. Considering the utility of such application in mind, a computer software program in MS Excel and a mobile based application have been developed for Stem and Stump Analysis. Both the applications have been checked with data collected for Cedrus deodara at Kanasar, Chakrata Forest Division, Dehradun and the results obtained are highly satisfactory. This paper discusses the method used in developing these applications and efficacy and utility of both the applications in preparation of working plan and volume tables.

Subject: Appraising Quality of India's Green Cover in Terms of Growing Stock
Keywords: Forest Cover, Growing Stock, Assessment, Recorded Forest Area, Green Cover, Productivity/Quality.
Abstract: Quality/productivity of green cover may be appraised in various ways and in different contexts. The present study attempted to evaluate productivity in terms of GS analysing data published in ISF Reports. It worked out trends in productivity in terms of quantity of GS per unit area within RFA, status of GS outside RFA and quality of green cover (FC+ tree cover) at National and State level by analysing the assessments of GS made by FSI so far. While highlighting constraints in the convergence of forest cover with GS in forests and tree cover with GS in TOF, the study brought to light a reduction of 583.02 million cum GS @ 7.19 cum per hectare in India's recorded forests from 1993 to 2015. The comparison of first biennial (2003) assessments of GS with the latest one (2015) figured out decrease in GS within RFA by 586.36 million cum @ 48.86 million cum per year. The analysis also unfolded that the initial GS assessments (1993, 2003 and 2005) owing to small no. of sample plot were not comparable to the later assessments (2009 to 2015). Therefore, analysis of later assessments (2009 to 2015) brought out reduction of 329.813 m cum (303.61 million cum within RFA and 26.2 million cum in TOF) in GS of the country (both in forest and outside forest) in spite of 10577.08 km2 increase in the total green cover construing thereby enhancement in the extent of green cover but downturn in quality. The annual rate of decrease in GS worked out as 54.969 million cum (50.6 million cum within and 4.37 million cum outside RFA) from 2009 to 2015.Likewise the productivity in terms of GS per unit area of green cover (in forest + in TOF) declined from 77.816 cum/ha. in 2009 to 72.627cum/ha in 2015 though the decline was sharp @ 5.546 cum/ha. in 2013 which mildly recovered thereafter.

Abstract: Bioethanol and hemicelluloses are the most abundant renewable biomacromolecules found in the biosphere. Bioethanol has received special attention worldwide due to gradual depletion and increasing price of fossil fuels. Bioethanol from cellulosic biomass has gained popularity because of convenience in processing and economic nature. In the present study, chemo-enzymatic saccharification of jack fruit peel waste employed which yielded p to 30.58 g/l of reducing sugar. Fermentation was carried for bioethanol production by using filtrates of treated jackfruits peel extract with Saccharomyces cerevisae. Bioethanol yield was monitored throughout a fermentation period of 5 days; bioethanol yield was found to be a maximum of 3 g/l from Jack fruit peel waste hydrolysate after distillation. The use of jackfruits peel for the production of bioethanol shall provide with a novel perspective to recycle organic waste for renewable energy.

Abstract: Hybrid composites of teak wood flour/cotton stalk flour and polypropylene were fabricated at a fixed plastic to fiber ratio of 80:20 and variable proportions of the two fibres by extrusion method. Maleic anhydride grafted polypropylene (MAPP) was used as the coupling agent. The tensile specimens of neat PP and hybrid composites were subjected to 25 kGy dose of gamma radiation. The tensile strength was estimated using Universal Testing Machine (UTM). Thermal analysis of the samples has been carried out at a heating rate of 10ºC min-1, from 50ºC temperature to 500ºC, in a n inert atmosphere. The outcome of gamma irrardiation on thermal and tensile properties was analysed. A notable improvement in tensile strength and tensile modulus has been observed, with modest decline in thermal stability. The improvement in tensile strength of hybrid composite as compared to neat PP, can be attributed to the cross-linking effects of both the compatibiliser and the gamma irradiation.

Subject: Prospects of Cultivation and Commercialization of Seabuckthorn
Keywords: Leh, Seabuckthorn, Socioeconomics, Value addition
Abstract: Seabuckthorn (Hippophae spp) is a perennial, thorny bush with yellow berries in the cold desert region of Leh in Ladakh. Seabuckthorn is popularly known as ‘Wonder Plant’, ‘Ladakh Gold’, ‘Golden Bush’ or ‘Gold Mine’ of cold deserts. It is rich in pharmaceutical, therapeutic, and cosmetic values and serves as a source of multivitamins and food supplement. Besides, it also contributes to fix nitrogen in the soil making it more fertile. The shrub can withstand extreme temperature from -43ºC to +40 ºC and is considered drought resistant. These two characteristics make the shrub an ideal plant species to establish in cold deserts. It is naturally distributed over 11, 500 hectares in Ladakh region. Seabuckthorn commonly grows on forest department land, wastelands, along the riverbed and the monastery land. Monasteries use it extensively as fuel since it makes excellence coal. It is estimated that seabuckthorn plantation fix 180 kg nitrogen per hectare every year. This study essentially looks at the opinions of various stakeholders in the region. What has emerged from this study is that the seabuckthorn trade needs to develop into an industry. This basically means that the current production has to significantly scale up, more value addition done, newer and more secure markets to be explored and more employment opportunities created for the local people. The different components pertaining to setting up of an enterprise like the form of organization, fundraising, operations and management and legal aspects need to be further explored. Economic integrity of Seabuckthorn plant in Leh and its adjoining areas upgrade the integrity of Seabuckthorn plant in Leh and its adjoining areas upgrade the economic stability to the local inhabitants. The data on economic probability of cultivating seabuckthorn orchards amounts to Rs 255387.60 ha-1 discounted at an interest rate of 12 % during the rotation period of 6 years. The gross and net income realized from this plantation after six-year rotation cycle is Rs 479577.02. The present analysis also reveals that the farmer can realize NPV of Rs 224189.41 ha-1 with equivalent annual annuity of Rs 54528.63 and can get Rs 1.88 for every rupee invested at an interest rate of 12%.The products made from seabuckthorn berries in Ladakh have both local and national demand due to nutritive value. The result of the survey conducted in the local market reveals that Seabuckthorn products in Ladakh and adjoining areas are sold with 50 to 300 per cent after value addition. In addition, six-year-old seabuckthorn plantation on one hectare can produce 18 tons of firewood which is equal to nearly 12.6 tons of standard coal.

Subject: Developmental Activities in Relation to Change in the Diversity-Distribution of Medicinally Important Plants in Vicinity of Serlui-B Hydel Project, Mizoram, India
Keywords: Developmental activities, Diversity-distribution, Medicinal plants, Serlui-B- dam.
Abstract: Dams are beneficial to the society in many ways, but developmental activities on construction site have detrimental effects on plant wealth and certain medicinal species are eliminated eliminated before fully assessed and validated. The findings of the present investigation on diversity distribution of medicinal plants under undistributed and distributed forests stands in the vicinity of Serlui-B hydel Project in Mizoram reveal that there is a drastic change in the plant community structure and botanical composition. Altogether, 140 species (118 species from 104 genera and 56 families in the undisturbed stand and 71 species from 63 genera and 31 families in the disturbed stand) belonging to 120 genera and 59 families were recorded from both the stands. The species sensitive to the disturbance were eliminated in the disturbed stand. From the ethnomedicinal knowledge inherent in some elderly aged local indigenous people it can be enumerated that most of the species recorded were used for the treatment of various ailments (fever, gastrointestinal diseases, dermatitis, dental, respiratory, cardiac, cuts and wounds).Habit-wise distribution of species indicates pre-dominance of woody species and herbaceous species in the undisturbed and disturbed stands, respectively. The shift in position of the species and habit-wise changes could be linked with disturbance at a large.

Keywords: Intercropping, Agric-horticulture; Emblica officinalis; Andrographis paniculata, Agroforestry
Abstract: A field experiment was conducted to determine the feasibility of intercropping Andrographis paniculata Nees. and Emblica officinalis Gaertin .at Dryland Regional Sub Station of Sher-E-Kashmir University of Agricultural Sciences and Technology of Jammu. The objectives were to study the effect of ten-year-old Emblica officinalis trees on the growth and yield of Andrographis paniculata. Andrographis was intercropped at three different spacing viz., 30 cm X 45 cm; 30cm x 30 cm; 45 cm x 45 cm. Recommended spacing of 30 cm x 45 cm without trees served as control. The results showed that due to competition among the various components of the system, Andrographis paniculata grown as an intercrop registered a decrease in growth and productivity compared to open. However, on practical point of view, out of the three different spacing, plant spacing of 45 cm x 45 cm was found most suitable for successful cultivation of Andrographis paniculata as an intercrop under Emblica officinalis. We concluded that Andrographis paniculata-Emblica officinalsis intercropping system can be practical and beneficial in the region. However, the distance between crops and tee rows should be adjusted to minimize interspecies competition.

Subject: Enhancing productivity of Ailanthus Excelsa Roxb.by planting Grafted Female Trees
Keywords: Dioecious, Grafting, Clones, Biomass and Economics
Abstract: Alilanthus excels (Ardu), a dioecious tree species, is an important fodder tree of Rajasthan. It is also valued for timber, fuel-wood and ethno-medicines in many parts of India. Literature and field observations indicate that female plants of this species exhibit better growth forms as compared to male plants. However, it is hard to identify female plants at the sapling stage. Cloning of Ardu through macro and micro-propagation methods is difficult and economically non-viable. Using grafting method developed and improved byArdi Forest Research Institute (AFRI) a trial of male and female plants was established inAugust2008.The result shows that female trees are superior to male trees in all the parameters except the length of primary root. Maximum difference was observed in the leave fresh (fodder) weight and number of branches, in which 71% and 69% higher biomass was recorded in female plants, respectively. Economics of this trial revealed that the higher cost of raising grafted female plantations is recovered within five years through fodder component only. Twenty per cent higher wood (timber and fuel) production by female plants is a benefit over plants raised through seedlings with an assumption that plantations raised through seedlings have 50 % male plants.

Subject: Effect of Four Land uses on Soil Edaphic Properties and Soil Organic Carbon Stock in Mizoram, North-East India
Keywords: Land use types, Soil physic-chemical properties, Soil depth, Soil organic carbon stock
Abstract: The present study was aimed at assessing the effect of four land uses namely properties and soil organic carbon in Lawngtlai district of Mizoram, northeast India. A permanent plot of 250 & 250 m was demarcated in each land use and soils were collected randomly from four points at depth 0-20 cm, 20-40 cm and 40-100 cm within the plot. Bulk density, soil texture, soil moisture content and soil pH were estimated .Bulk density was lower in dense forest as compared to the other three land uses and increased with increasing depth. Soil moisture content and pH were found to be highest in dense forest. All the land uses were grouped under sandy textural class. The highest mean SOC concentration (%) for the entire soil depth (0-100 cm) was found in dense forest and the least in open forest with 4.06% and 1.88 % respectively. All the land use types followed a pattern of SOC concentration decreasing with increasing depth. The highest mean SOC stock for the entire depth was recorded in dense forest with 88.66 Mg C ha-1 and least in pine plantation with 49.16 Mg C ha-1 .SOC stock in 0-40 cm in all the land uses accounts for more than 50% of the total SOC stock up to 1 m soil depth. The estimated highest SOC stock loss was observed when dense forest is converted to pine plantation ( 39.5 Mg C ha-1) followed by dense forest to open forest ( 39.15 C ha-1) and dense forest to grass land ( 20.7 Mg C ha-1) .
