Trees were selected in eight different directions and in each direction five distances were taken in the vicinity of cement factory for collecting the seeds and to observe their germination and growth parameters. It was observed that seeds collected from control sites (10 km away) from the factory, showed significantly higher germination and growth parameters compared to those collected near the factory.

This article surveys predicted and projected rates of glohal warming and climate change due to emission of GHGs and their consequences especially effects on nature , society , glaciers and stream flow , agriculture and fauna. Effects on forests may result in shift of species , drop in productivity and growth , increased incidence of insects. To counter these problems , a worldwide strategy has to be taken up to mitigate or slow down these processes. In this strategy the international agencies can playa dominant role in fixing targets for reduction of emission. Geo-engineering can be put to use but the forests have the biggest opportunity as they absorb CO2 and function as carbon sinks. The introduction of carbon credits is advocated , as an incentive.- Effect of Initial Collar Diameter, Shoot Pruning and Root Pruning on Performance of Planting Stock of Celtis australis

The planting stock of Celtis australis having collar diameter (1.0 to 1.50 cm), shoot pruning (6 cm above collar) and no ischolar_main pruning are recommended for better establishment of the seedlings in degraded tracts of mid hill zones of Himachal Pradesh.- Biomass Production Potential and Nutrient Dynamics of Populus deltoides under High Density Plantations

The experiment on Populus deltoides was laid out in randomised block design with three densities viz 60 cm x 60 cm (27,777 plants/ha), 90 cm x 90 cm (12,345 plants/ha) and 120 cm x 120 cm (6,944 plants/ha) under rainfed conditions in mid hill zone of Himachal Pradesh. The plantation harvested after 13 years, produced maximum biomass (218.08t/ha) in the closest spacing of 60 cm x 60 cm for which the bole contributed 90.71 per cent of the total above ground biomass accumulation. The nutrient accumulation in the biomass also differed with the density. The maximum nutrients were present in the closest spacing. It was further observed that organic carbon content in the soil decreases with the decrease in density. Conversely, an increase was observed in nitrogen, phosphorous and potassium content of soil with the increase in spacing. Study reveals that accumulation of nutrients in the biomass is higher in 60 cm x 60 cm spacing whereas, the nutrient return through litterfall was less as compared to the total uptake which created nutrient deficit in the soil.- Wood Characteristics of Populus deltoides as Affected by High Density Plantation

Among the three species planted Elaeagnus umbellata was observed to have maximum survival and growth performance then Coriaria nepalensis and Indigofera pulchella, in both sandstone and limestone mined areas. In sandstone mine it registered 82.50 percent survival, whereas, in limestone it was 91.37 percent. Addition of 2.5 kg forest soil per pit increased the survival and growth performance in both the mines, except that of diameter and ischolar_main: shoot ratio which was observed more in mine spoil alone (control).- Allelopathic Effect of Eucalyptus - a Myth

Soil organic carbon (SOC) change can arise because of changes in land use, land management and climatic conditions. Modelling approach helps in proper choice of management practices for soil carbon build-up. In this context, RothC is a promising model for estimation of SOC changes in different land-use systems. In the present study, RothC model was used to predict the development of SOC in Populus deltoides plantation during three rotations in three agro-climatic zones of the Indo-Gangetic region, India. The result reveal that RothC fairly predicts SOC. Root mean square error for Lower Gangetic Region (LGR), Middle Gangetic Region (MGR) and Trans Gangetic Plain (TGP) was 2.75, 4.94 and 1.30 respectively, while comparing modelled and measured data. Model efficiency was 0.25, 0.36 and 0.89 for LGR, MGR and TGP respectively. The rate of change of measured SOC was 1.0, 1.59 and 1.51 mg ha–1 year–1 for LGR, MGR and TGP respectively, whereas the rate of change of simulated SOC was higher, i.e. 1.16 and 1.89 mg ha–1 year–1 for LGR and UGR respectively, and lower for TGP (0.97 mg ha–1 year–1).Keywords
