Abstract: Thirty two isolates of Azospirillum were isolated from the teak growing areas of Andhra Pradesh, Kerala and Tamil Nadu in South India. The isolates were identified, mass cultured and mixed with carrier material and inoculated to tissue culture raised plantlets of teak in nursery condition to test the efficacy of the isolates on the growth, biomass production and the overall quality of the plantlets. It was found that the isolates ACH-4 (Andhra Pradesh) and KNI-2 (Kerala) were the most potential ones for the growth improvement of the teak plantlets. An attempt was made to determine the synergistic effect between these 2 isolates and it was observed that application of both the isolates put together, not only enhanced the growth but also increased the biomass and the quality of the plantlets.

Abstract: Toxicity of Ivermectin (Ivecop-12)-was evaluated against the larvae of a major defoliator of Teak, Hyblaea puera Cramer, during the outbreak period (July-August) in teak (Tectona grandis L.f.) forests of central India. The study was conducted once with eight treatments of higher (lethal) concentrations and then thrice with eight treatments of lower (lethal and sub-lethal) concentrations. Results revealed that ivermectin is highly toxic which could induce larval mortality when applied on host plant leaves and larvae together of the insect pest. Toxicity of ivermectin was found to be effective at ppm level and knock-down toxicity was noticed to be very rapid. Among the concentrations of ivermectin tested, cent per cent mortality was recorded by the higher concentrations up to 1172 ppm (0.001172%) and significantly different (P<0.01) from other treatments of lower concentrations including control. Further, there was a gradual decline of larval mortality with respect of lowering concentrations of the ivermectin. The LC50 value of the tested biological product was worked out to be 282 ppm (0.000282%) against the target insect pest.

Abstract: Genetically improved clonal planting stock of Eucalyptus, Poplars and Acaicas has tranformed the productivity and profitability of plantations. Average yields from such clonal plantations are 20 to 25 times higher compared to the average productivity of forests in India. Current levels of clonal Eucalyptus and poplar plantations produce nearly 5 million cubic meters wood valued at 21,000 million rupees annually. Plantations sustain most of the wood based pulp and paper mills and plywood/veneer factories in the country saving precious foreign exchange. Well managed clonal Eucalyptus plantations covering 1.25 million ha. can meet country ' s entire pulp and paper requirements projected at 8.5 million tonnes by 2010-11. Likewise, high yielding, short rotation clonal Eucalyptus plantations on part of the degraded forest lands can meet country ' s fuel -wood needs on sustainable basis. Clonal plantations, both on degraded forest lands and under agro-forestry system, should be encouraged and integrated with planned development of wood based industries through innovative policy changes.

Abstract: Geographic Information Science (GIS), when used in combination with remote sensing provides a useful tool for mapping and management of rare and endangered plant species in Meghalaya, India which is a biodiversity hot spot region. The first step in this exercise is creation of polygon wise forest management inventory that would comprise details of threatened and endemic species in the area along with habitat conditions viz vegetation type, forest cover class apart from the stand characteristics namely wood volume etc. The second step is to overlay such polygons on land use classification map generated from remote sensing imageries through visual interpretation technique. Such a map created in ESRI Arc MAP would be useful to resource managers for outlining the present and future management plans towards conservation of a biodiversity rich region. A supplemental tool in this managerial exercise is visual polygon decomposition technique that provides precise information on the state of habitat and vegetation cover preservation apart from the trend it is likely to follow in the near future. Such an analysis is indispensable in areas like Jaintia hills district of Meghalaya where industrial citing activity has just begun exerting severe anthropogenic pressure on hitherto virgin habitat.

Keywords: Biotic components, abiotic components, Pinus roxburghii, Quercus leucotrichophora
Abstract: Physico-chemical characteritics of forest soils differ in space and time because of variations in biotic and abiotic components viz., topography, climate, weathering process, vegetation cover, microbial activities etc. Vegetation plays an important role in soil formation (Champan and Reiss, 1992) because plant tissues (above ground litter and belowground root detritus) are the main source of soil organic matter, which influences soil pH, water holding capacity, texture and nutrient availability (Johnston, 1986). Each ecosystem vary in nutrient supply with other (Binkley and Vitousek, 1989), thus the resultant production and community structure of vegetation too differ (Ruess and Innis, 1977). Quercus leucotrichophora, a moderate to large sized evergreen tree occurs in the moist and cool climate. It is a principal species of the lower west Himalayan temperate forest and is exploited for fodder by locals. It grows on a wide variety of geological formations and soils, such as shale gneiss, schist, quartzite and lime stone rocks and mostly sandy or clayey loam soils (Luna, 2005). Pinus roxburghii is the most common resin yielding conifer species of India. It is a large evergreen tree and a principal species of the Himalayan sub-tropical forest (Champion and Seth, 1968). The study examined the differences in nutrient status of the soils under P.roxburghii and Q.leucotrichophora forests which are dominant and have importance in Garhwal Himalaya region.

Keywords: Chir pine, Chamba district
Abstract: Climate and its variability have been and continues to be the principal source of exceptional fluctuations which have wreaked havoc on forests. In Chamba, up to an elevation of 1,800 m Chir pine (Pinus roxburghii Sargent) is the main naturally occurring coniferous tree in forests. Best plantations of this tree flourish on sandstone intercalated with various types of clays (Gupta, 1980). plantations of Chir pine are also being raised on degraded slopes for increasing forest cover and also meeting teh increasing timber demands. Owing to considerable geological instability, the whole of the region is very fragile adn susceptible to erosion. The exceptionally high rainfall coupled with heavy snow fall further aggravates the problem. Therefore, a field survey was conducted to record teh extent of damage caused by exceptionally high snowfall and incessant rains of winter of 2005 to Chir pine trees growing on steep slopes and unstable strata of Chamba district of Himachal Pradesh.

Abstract: The study was undertaken to analyse the price behaviour in terms of trend, seasonality and cycles in prices of lac in important primary, secondary and terminal markets of West Bengal. The secondary data on monthly average prices of lac at primary, secondary and terminal markets were collected for a period of 16 years spanning from 1990-91 to 2005-06. A positive trend has been shown in prices of Kusmi lac during the study period which was statistically significant at one percent probability level for all three levels of market. Growth rate of kusmi lac prices at growers, assembling centres, manufacturing centers and Kolkata market were found to be 10.16, 10.03, 9.06 and 7.72 percent per annum, respectively. Increase in price at growers level and assembling centers were comparatively higher than that of price increase at manufacturing centers and Kolkata market. Only one peak of prices have been observed at growers and assembling centers level while two peaks of prices have been observed in case of manufacturing centers and Kolkata market. No regular cycles have been observed in the kusmi lac prices during the study period. Intra year price variation was more at growers and assembling centres level in comparison to manufacturing centres and Kolkata market. The seasonality in prices can be reduced by sustained production, production in diverse agro-climatic condition, primary processing of lac at village level and integration of lac production in various lac growing regions of the country.

Abstract: The study was carried out at farmers fields to quantify nutrient harvest through biomass of pruned material of 2, 3, 4, 5 and 6 year old plantations and whole tree of Populus deltoides Bartr. (Poplar). The pruned biomass was 327.4, 426.96, 986.27, 1,234.91 and 1,558.59 kg ha-1 at 2,3, 4, 5 and 6 year old plantations respectively. The total biomass of branches, main stem and root of poplar at exploitable age was 48,96, 89,144, 94,040 and 12,280 kg/ha, respectively. Nutrient concentration was increased from basal segment to terminal segment of pruned branches and decreased with size of the branches. The nutrient harvest through pruned biomass was 46.32 kg ha-1 N, 6.92 kg ha-1 P and 19.93 kg ha-1 K whereas nutrient loss through whole tree was 652.8 kg ha-1, 75.84 kg ha-1 P and 719.84 kg ha-1K. As the nutrient is exceeded than annual return, additional doses of fertilizers may be required to maintain soil fertility and productivity of the system.

Abstract: Phenology of 39 species of shrubs and trees was studied in the Sariska Tiger Reserve Forest in North-East Rajasthan. The leaf fall, leaf flushing, flowering and fruit development was studied from December 2001 to November 2002. There were 24 deciduous woody species which represented more than 90 percent of the vegetation in the study site. Leaf fall began from September onwards with the retreat of monsoon, attaining a peak value in February when about 35 percent species were leafless. Leaf initiation began in hot and dry summer season from April untill the end of June when all the species had produced new leaves. Flowering and fruit development occurred throughout the year with one peak in hot and dry summer (March to April) and the another in rainy season (July to August). Thirty three percent species flowered in the summer season followed by 26 percent in the rainy season. Only three woody species produced flowers in the cold and dry winter season (December to January).
