Abstract: An investigation was under taken to monitor the performance of tree growth and crop yields of paddy and wheat under Eucalyptus tereticornis Sm. based agri-silvicultural system at farmer ' s field of Amaniganj block of Faizabad district. The -1 -1 average annual growth in tree height and dbh were 1.24 m and 0.89 cm tree yr , respectively. The light intensity recorded was maximum in open crop than under tree canopy. The results indicated that paddy grain yield was 14.7- -1 -1 19.7% less under tree canopy (1.99 t ha ) than open area (2.34 t ha ). However, under tree canopy, the wheat grain yield -1 (1.49 t ha ) was 26.4-34.6% lower than that of open cultivation. It is evident from the experiment that paddy tolerates little suppression of reduced light under tree canopy and does not face too severe decline in grain yield. On contrary, wheat being a strong light demander experiences relatively greater suppression in grain yield.

Keywords: Biomass, Carbon, Himalaya, Density.
Abstract: Forests often store carbon at rates well below their potential and thus could be responsive to the management of enhanced carbon sequestration. The present study was carried out in Duggada area of Garhwal Himalaya to assess tree biomass and total carbon density. The dominant tree species were found Salix tetraseprma, Toona hexandra, Emblica -1 officinalis and Acacia catechu. Total carbon density was 525.15 mg ha and ranged between 81.27?4.82 for Bischofia -1 -1 javanica to 4.38?0.29 mg ha for Ficus religosa. Total tree biomass density (TBD) was 1050.30 mg ha and values varied -1 from 162.54?9.65 in Bischofia javanicato 8.77?0.59 mg ha for Ficus religosa. However, value of below ground biomass density (BGBD) was 806.95 and range between 128.8?7.85 for Bischofia javanicato 6.41?0.45 in Ficus religosa.

Abstract: Precise mapping of Kaziranga National Park (KNP), the natural world heritage site, is the prime objective of this paper. High resolution Indian remote sensing satellites including IRS P6 Panchromatic and LISS 4 image, with 2.5 m and 5.8 m spatial resolution respectively, were used for the same along with GPS and extensive field survey. A theme based hybrid approach was followed for classification of digital remote sensing images. The overall classification accuracy was estimated to be 91.7% where as K value implies that the classification process was avoiding 89.9% errors of a hat completely random classification. The Eastern alluvial grassland is found to be the predominant vegetation type which occupies 50.6% of the total park area. Semi-evergreen and moist mixed deciduous forests together occupy 21.8% of the total area followed by short grass (7.7 %). A substantial area (11.7%) was found to be eroded in to the river Brahmaputra and as a result core area of the park is found to be decreased when compared with previous assessments.

Abstract: Inventory of the growing stock based upon stratified random sampling has been applied to estimate the timber resources in the forests. This method cannot give precise estimate of NTFPs yielding herbs and shrubs with patchy and clustered distribution. Our field study in the forests of Chittoor district of Andhra Pradesh indicates that inventory of a shrub named Decalepis hamiltonii, an important NTFP tuber species is best estimated with the help of ' Adaptive Cluster Sampling ' applying the Horvitz - Thompson estimator. This method can be replicated for other species with similar distributions. Precise inventory coupled with productivity assessment is required to standardize management prescriptions.

Abstract: Forest patches under Bardhaman Forest Division, West Bengal (covering an area of 7024 km2) were chosen for phytospectroscopic study. Out of total of 382 species of vascular plants, percent values of phanerophytes, chamaephytes, hemicryptophytes, cryptophytes and therophytes are 46.86, 20.16, 12.83, 11.78 and 8.38. Phytoclimate is phanero-chamaephytic under moist, warm, humid tropical monsoonal geoclimate. In the forest patches, canopy is disturbed with gaps to allow sunlight, this would result in microhabitats, regeneration- niche of trees and regeneration-status of the forest. Soil is at the risk of erosion and there prevail certain stress factors. Comparative phytospectroscopic study on different sites reveals that if proper conservational support is provided to the forest patches by including them in Protected Areas Network (PAN) in the form of Sanctuary or National Park, phanerophytes would gain further numerical strength confering the ecosystem more purity and more active community metabolism. This is the signature of the still active potential of the community to nurture high level of biodiversity.

Abstract: The vegetation of study area is broadly divided into four physiognomic units viz,. forest, secondary forests, grasslands and artificial vegetation. Shannon ' s diversity index, species richness and species composition of the vegetation of study area has been worked out. A total of 944 plant species richness and specie composition of the vegetation of study area has been worked out. A total of 944 plant species belonging to 510 genera and 130 families are reported from the study area. The y-diversity of the study area is 4.292. Plant species diversity in different concrete plant communities has also been determined. The species diversity of total forested area is 4.115. Among different forest stands sal forest exhibit maximum species diversity (H ' = 3.530). The grasslands as a whole showed high diversity (H ' = 4. 198) with maximum contribution of erect annual herbs. Mesic grasslands show maximum species diversity (H ' = 3.907) among different grassland communities. Shrubs contribute maximum to the species diversity in degenerated forest. Climbers contribute very less to the species diversity of all the communities. The study area harbours some of the rare and threatened species needing effective conservation measures. An attempt has been made to deduce the successional pattern and affinities among different plant communities.

Abstract: Genetic variability in Jatropha curcas was induced by different doses (5, 10, 15, 20, 25, 30, 35, 40, 45 and 50 kR) of gamma-rays. Gamma radiation induced earliness in flowering and the plants set flowers earlier than that of normal (control), which took longer duration of 327 days for flowering. The improved reproductive and yield parameters such as days taken to first flowering, flowering population, male to female ratio and seed yield per plant were recorded in 25 kR dose and seed germination in 5 and 10 kR treated seeds. Molecular characterization of induced mutants (M1 generation) with 47 RAPD primers showed 65.27 per cent polymorphism. The variability created by gamma rays ranged from 9 to 28 per cent. The 50 kR mutant was found to be the most diverse from control followed by 25 kR mutant. Thus, this integrated approach can be used for carrying out the mutation-assisted breeding and subsequent selection of desired mutants using molecular markers in J.curcas.

Abstract: The present investigation was carried out to record changes in physico-chemical properties of vermicomposted coal mine spoil and to find out promising species for its reclamation. Four dozes of vermi-compost and vermin-leachate and 3 dozes of vermin-leachate were applied per 150 kg of coal mine dumps. To each treatment, sand was incorporated @ 7.5kg, 15kg, 22.5kg, and 30kg to enhance spoil porosity. The results indicated that pH of the treated spoil was decreased. Ninety viable seeds of Acacia nilotica, Swietina mahogany, Dalbergio sissoo and Prosopis juliflora were sown in each treatment and each treatment replicated three times. Biometric parameters viz,. germination, survival percentage, plant height and number of branches of seedlings were recorded at end of 2nd month. Acacia nilotica was found to be most promising species for coal mine dumps spoil. Hence amendment of organic fertilizer leads to enhance spoil porosity, organic carbon for the better environment for the plantation of forest species in coal mine dumps.
