Abstract: Beetle of Phloeobius crassicollis exhibit sexual dimorphism. The emergence of beetles occurred during May-June. The newly emerged beetles feed on the outer surface of the bamboo culm recurring preferably at the nodes. Single gravid female laid 40-45 eggs at nodes/culm sheaths. The longevity of female and male beetles is 22.6?0.57 and 18.5?0.38 days respectively. The sex ratio male: female is 1.00:0.917. The freshly laid eggs are light gray and oval, incubate for 11.20?0.27 days at room temperature. The freshly hatched larvae nibble and scratch at the point of hatching on the nodes/culm sheaths. Larvae feed on woody tissues of nodes and internodes and deposit the larval frass inside the hollow internodes. The body colour of larvae was creamish with dark yellow head. The larval period was 317.6?0.14 days. Pupae were grayish black in colour. The length and breadth of pupa was 15.00 ?0.316 mm and 8.4?0.155 mm respectively. It emergedinto adults after 17.2?0.63 days.P. crassicollis taken one year to complete the life cycle.

Abstract: Lasiodiplodia theobromae, a fungal pathogen causing stem cankers on Dalbergia sissoo is reported in Haryana and Punjab for the first time. It might have reached to D. sissoo from fruit trees like pear and peaches grown in the area where this fungus was reported earlier. The disease exhibited symptoms like dark spots on the bark with splitting, cankers and oozing of sap. The affected trees showed die back to varying degree. Bavistin was found as the most effective fungicide inhibiting complete growth of the fungus at 100 ppm among other fungicides. Among biological control agents Trichoderma harzianum exhibited distinct antagonism, T. koningii exhibited mycoparasitism, T. viride showed inhibition at the line of contact whereas Aspergillus niger showed overlapping. Spraying with Bavistin or Trucop on stem, branches and twigs of affected trees is recommended for checking the further spread of the disease. Chaubatia paste can also be applied while pruning the trees to check entry of the pathogen.

Abstract: The carbon storage potential of Eucalyptus tereticornis plantations (one to four years old) was estimated using two different methods. The carbon concentration in different parts of the tree for all aged plantation was found in decreasing order: stem > root > branch > leaf. Carbon content of litter showed that the lowest return was from the youngest and highest return was from the oldest stand. The carbon content was found to be 38.10 t ha-1 (one year plantation) and 115.88 t ha-1 (four year plantation) when estimated by biomass and carbon content per cent (formula method) and it was found to be 42.66 t ha-1 (one year plantation)and 129.04 t ha-1 (four year plantation) when estimated by the assumption that carbon fractions is fifty per cent of biomass (assumption method). The results showed that the assumption method leads to an over-estimation of carbon content for the total organic carbon of the same age when compared to the formula method (especially for younger aged plantations).

Abstract: The world continues to seek economically and environmentally sound alternatives to fossil fuel-based transportation of fuels and power. Energy crop Jatropha curcus L provide an attractive combination of high yield density, high net energy balances, low input requirements and has potential to be tailored for specific production and refining processes. Present study was conducted to evaluate the effect of pruning and fertilizer on growth and yield of Jatropha curcas L. There were three pruning intensities viz., P0 (No pruning), P1 (45 cm) and P2 (60 cm) and four levels of fertilizer viz., F0 (No fertilizer), F1 (60:60:60 g NPK plant-1 ), F2 (80:80:80 g NPK plant-1 ) and F2 (100:100:100 g NPK plant-1 ). A clear decreasing trend was observed from F3 to F0 in almost parameters under study. Interaction effect between intensities of pruning and levels of fertilizer was found non significant in all growth parameters of Jatropha curcus L. From this study the significant yield increased by P2 (60 cm) pruning and F3 (100:100:100 g NPK plant-1 ) level of fertilizer gave best result 2 3 for getting higher yield and vegetative growth of Jatropha curcas L.

Abstract: This study aims to determine the stand density, basal area and above-ground biomass (AGB) of two plantations, Eucalyptus plantation (EP) and mixed species plantation (MP) in the campus of Bharathiar University, Coimbatore -1 -1 (Tamil Nadu), India. Tree density was high at the site MP i.e. 468 stems ha than site EP (320 stems ha ). Whereas, in 2 -1 case of basal area, the fast growing Eucalyptus tree plantation site had greater value 9.42 (? 0.15) m ha than site MP 2 -1 -1 8.67 (? 0.11) m ha . Also, site EP had greater AGB value 41.78 tonne ha (? 0.7 SD) when compared to the mixed -1 plantation which had 34.47 tonne ha (? 0.52 SD). However, T-test showed that there was no significant difference in AGB (t = 0.131, P < 0.05), density (t = 0.005, P < 0.05) as well as basal area (t = 0.297, P < 0.05) between the two study sites. There was a positive correlation (p > 0.05) between AGB with tree density and basal area at both sites. When compared, AGB of the present study falls within the range reported worldwide.

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.

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.
