Studies on measuring CO2, CH4 and N2O fluxes from five agroforestry systems viz., teak, jatropha, pongamia, simaruba and leucaena were conducted in semi-arid alfisols. This study gives an idea of successive potential values of GHGs in agroforestry systems to compare with carbon sequesteration abilities of these systems.

A field experiment was conducted during 2003-04 and 2004-05 at Research Farm, BHU, Varanasi, U.P. to study the effect of various sources (farm yard manure, vermicompost and poultry manure) and rates of organic manures on yield, quality of produce, soil quality and economics of rice-table-pea-onion cropping sequence.

Soil and plant samples collected from different sites receiving sewage and tube-well irrigation in Sangrur District of Punjab were analyzed for heavy metals to ascertain pollution potential.

The present study analyses the effect of a paper mill on epiphytic lichen communities in Barak Valley, Assam. Lichen thallus size, thallus number and frequency of occurrence, along with diversity of lichens at three levels (species, generic and family) are considered as variables to see the community composition across the distance from a paper mill.

To disseminate Insecticide Resistance Management (IRM) strategies, 10 villages were adopted in Muktsar district of Punjab during 2008 and 2009. Two villages were kept as check (Non-IRM) for comparing the impact of IRM strategies on the major insect pests and natural enemies in Bt cotton arthropod fauna.

Agro-climatic resource inventory characterization in spatial domain can play a great role in site specific suitability of sustainable agricultural crop production. An attempt has been made for creation of spatial database and zoning of agro-climatic resources of Punjab in spatial environment using GIS approach. This zoning approach divided Punjab into five zones for temperature and seven zones for Length of Growing Period (LGP).

Understanding the growth dynamics of urban agglomerations is essential for ecologically feasible developmental planning. The inefficient and consumptive use of land and its associated resources is termed sprawl. By monitoring changes in the urban sprawl over a period of time, the impact of changing land use on land, ecology and environment system can be assessed.

Tree-ring chronologies of teak (Tectona grandis L.) at two sites, Mundagod and Shimoga, in Western Ghats of Karnataka were established. Both sites are influenced by climate varying with altitude and proximity to the Arabian Sea and the equator.

Biomass studies are fundamental to understand the dynamics of ecological systems and its distribution. It helps in determining the distribution and flow of materials in the ecosystems. The primary productivity of different vegetation types is of great importance for man as he is so much dependent upon plant products.

Twelve sewage and soil isolates belonging to genus Pseudomonas were screened for their ability to degrade and dechlorinate 2-chlorobenzoic acid (2-CBA), 3-chlorobenzoic acid (3-CBA) and 2,4-chlorobenzoic acid (2,4-DCBA). On the basis of growth of the isolates of three chlorobenzoates and their subsequent dechlorination rate, an aerobic Pseudomonas strain PNK-3 was selected for the study.
