Abstract: Nursery raised teak (Tectona grandis) seedlings were given different fertilizer levels of Nitrogen (N), Phosphorus (P) and their combinations to ascertain changes in growth (seedling height and collar diameter) and seedling dry weight. In general, the seedling growth as well as dry weight increased along with increasing doze Amongst individual application maximum seedlings growth and dry weight was indicated at 150 mg level of N. Although P application also indicated similar pattern, however N application was superior P application. In case of the combined use of N+P fertilizers, growth showed a clear-cut increase along treatments indicating maximum seedling growth (34.6 cm seedling height and 11.48 mm collar diameter) and biomass (65.62 g dry weight seedling-1) at 100 mg N + 75 mg P level). Significant linear relationship (r2 = 7.8 to 8.8; p<0.01) was evident for different parameters under study.

Keywords: Intercrops, poplar based agroforestry, Cropping season, Block plantation
Abstract: Results of a survey conducted during the harvesting of block plantations to diagnose the intercrops grown in poplar based agroforestry (PBAF) are presented here. Informations were collected from 220 sampled plantations from 172 villages, 69 tehsils, 28 districts in 4 states viz, Punjab, Haryana, Uttar Pradesh and Uttarakhand. Wheat was found as main crop grown in 51.67% cases followed by sugarcane, fodder (shorghum/berseem), maize, jawar/bajra, paddy, dhencha (green manure) and others. The intensity of cropping was more in winter (rabi) season than in summer (kharif) season. Farmers stopped growing intercrops much earlier in summer season than in winter season. Survey further identified intercrops grown in different locations from first year to harvesting age. Validation of the results with the information collected on intercrops in PBAF through field staff of Wimco Ltd was largely in consonance with the findigns of the survey. The sruvey also estimated planting of 24.34 million poplar saplings throughout the region of intensive poplar culture (RIPC) during 2009-10 planting season, out of which 58.38% were in compact blocks and 41.62% were as boundary plantations.

Abstract: A comparative study on livelihood of undisturbed forest village and relocated village is presented. Analysis revealed that agriculture as a sole occupation could not proivde livelihood to the tribal. The relocated village (Tetu in Amravati district) was settled on agriculturally poor soils. Denial of access for NTFP collection and poor agricultural productivity were the main factors that led to improvishment of villagers. Similarly, villages in Gondia district situated in similar domain/settings had relatively better soils, but could not support the population adequately. However, permission to collect NTFP mad the difference. It was also observed that apart from modernising agriculture, it is essential to impart skills to the villagers to derive income from sources other than agriculture (e.g. pisciculture, poultry) before displacing them. It was also apparent that the relocation on fringes of forest with poor soils could force tribal to utilize forest resources without heed to conservation. The policy for relocation thus needs to be formulated based on the findings.

Abstract: The western part of the Rajaji National Park is the north-western limit of distribution of the Indian tiger in the world. Recent reports on the status of tigers in India indicates that the population in this part is threatened with imminent extinction since the all three tigers are females geographically and genetically isolated from the rest of tiger population in the Naitonal Park. Such situations exist in many parts of India and the paper discusses the crisis and suggests management intervention that may be used as a tool to overcome such critical situations in tiger conservation in India.

Abstract: Nodal segments taken from 40 yr old clump were surface sterilized using 0.1% (w/v) HgCl2 solution for 15-20 minutes and placed aseptically on media supplemented with 7.5?M BAP for bud break (79.16+ 7.22) and it was observed within a period of two weeks. Sprouted shoots were excised along with small piece of mother tissue and kept on medium supplemented with 5.0 ?M BAP for multiplication for 4-5 subculture cycles. Bunch of three shoots exhibited faster shoot multiplication when cultured on multiplicaiton media. During multiplication phase, BAP alone proved to be superior to kinetin. Microshoots exhibited higher rooting percentages on media supplemented with IBA than other auxins (IAA or NAA). Effective IBA concentration was found to be 10? M on which 72.22% of propagules rooted. Hardening was effectively carried out on half strength MS media without growth regulators, vitamins and sucrose. Success was achieved in acclimatizing 73.33% rooted propagules on mixture carrying potting mix of sand: FYM: Soil in 1:1:1 in poly-tunnels. Acclimatized plantlets were successfully transplanted to pots.

Abstract: Present paper deals with intra-, inter-tree and inter-location variations inwood anatomical traits and specific gravity in seed raised plantations of Dalbergia sissoo Roxb. The materials were procured from State forest Department, Punjab. The site were located at Kharkan, Hoshiarpur (Site-I0, Dhirowal, Hosiyarpur (Site-II), Kamalpur, Amirtsar (Site-III) and Dharmkot, Ferozpur (site -IV). In all 12 trees were considered for the study. Intra-tree, both axial and radial, and inter-tree variations were significant for most of the wood traits except wall thickness and speciifc gravity for intra-tree radial variations. The increasing trend was obtained form pith to periphery and bottom to top for most of the wood traits.F-test
showed that variations due to site were sinigicnat to wood anatomical properties and specific gravity. The sites of lower rain fall showed higher wood anatomincal dimensions. Further, the trees of differetn sites were clustered together and indicated the influence of genetic on the wood tarits. It showed that genetic diversity played an important role even at the similar type of environment for wood-traits in seed raised plantations of Dalbergia sissoo.

Abstract: Cyanobacteria are a group of diverse Gram-negative organims that are one of the most primitive photosynthesizes. Attention is drawn towards the alterations in physiological changes in cyanobacteria exposed to pesticides stress. Synechococcus cultures were exposed to various concentration of the hervbicide hexzinone and the tolerant cyanobacteria were used to study the alterations in antioxidant activities, growth and lipid peroxidation levels. All parameters showed a high degree of susceptibility towards high doses of hexazinone. Recovered cyanobacteria showed lower MDA content and super oxide and peroxide radicals. The present findings suggested that high concentration of Hexazinone might modulate the antioxidative system of Synechococcus spp. A significant conclusion can be drawn from the findings that imporved tolerance to herbicide stress may be accomplished by increased capacity of antioxidant system of cyanobacteria.

Keywords: Non-Timber Forest Products,
Abstract: The species composition, dominance and regeneratin status of tree species were studied in two blocks of Achanakmar-Amarkantak Biosphere Reserve (AABR) namely [Block II (Periphery) and Block I (Interior)]. The tree density, sapling density and seedling density was higher in Block I as compared to Block II. In both blocks, GHB (Girth at breast height) showed decline in density from small girth class to higher girth class. The study also revealed the nature of changes effected on the character and composiiton of the biosphere reserve as a result of increasing anthropogenic disturbance and simultaneous changes in microclimate particularly in block I. As far as the regeneration status is concerned, maximum tree species was found with fair regeneration in the [Block I (Interior) than Block II (Periphery)] of the AABR. Meanwhile, in block II, nine species, while as in block I four species were not regenerated. There was lower species richness, species diversity, and mean height of trees in the block II which is a disturbed site, when compared with Block I the undisturbed sites. The seedling density and regeneration of plants were also lower in the disturbed site. Very few of the species extracted by villagers regenerated in the disturbed sites. This suggests that NTFP extraction is non-sustainable within the protected area and will eventually lead to loss of biodiversity and degradation of the forest.

Abstract: Plant resources are naturally occurring substances that are considered valuable in their relatively unmodified (natural) form. The value of such resources rest in the amount of the material available and the demand for it. Both extraction of the basic resource and refining it into a purer, directly usable form are generally considered natural-resoruce activities, even though the latter may not necessarily occur near the former. Conservation and sustainable use of plant resources means an occurrence of improvement by virtue of preventing loss or injury and careful management of the plant resources. The management process includes optimum utilization of natural resources in a scientific manner for the betterment of man and environment and for sustainable development.
