Evaluation of plant performance of Jatropha curcas L. under different agro-practices for optimizing biomass ― A case study

Abstract: Jatropha curcas L., a multipurpose, drought resistant, perennial plant belonging to Euphorbiaceae family has gained lot of importance for the production of biodiesel. The properties of the crop and its oil have persuaded investors, policy makers and clean development mechanism (CDM) project developers to consider Jatropha as a substitute for fossil fuels to reduce greenhouse gas emissions. However, basic agronomic properties of Jatropha are not thoroughly understood and the environmental effects have not been investigated yet. Grey literature reports are very optimistic on simultaneous wasteland reclamation capability and oil yields. Studies were undertaken at Solar Energy Centre, Gurgaon, India to evaluate the plant performance under different agro-practices with special reference to irrigation scheduling, VAM and biofertilizers' applications, plant spacing, pruning trials for maximizing tree architecture and higher biomass. Parallel experiments were undertaken to understand the scope of J. curcas for intercropping practices in the under storey of dominating monoculture tree stands (Prosopis, Acacia and Neem).

Characterization of winged bean (Psophocarpus tetragonolobus (L.) DC.) based on molecular, chemical and physiological parameters

Abstract: Winged bean (Psophocarpus tetragonolobus (L) DC) is a potential legume crop of the tropics with high protein and oil content in the seeds Analysis of the mutual genotypic relationships among twenty four genotypes of P tetragonolobus through Mantel test found a significant correlation (r = 0839) between similarity matrices of the results obtained from the use of the RAPD and ISSR molecular markers The UPGMA tree based on Jaccard’s similarity coefficient generated from their cumulative data showed two distinct clusters and seven sub-clusters among these accessions Quantification of total polyphenols, flavonoids and tannin revealed the highest percentage of occurrence of kaempferol (107-7905 μg/g) and the lowest percentage of gallic acid (009-349 μg/g) in the seeds Phytochemical analysis of the winged bean genotypes revealed that, some of the exotic lines are distinct Analysis of photosynthesis rate, photosynthetic yield and stomatal conductance data also showed two clusters and was in congruence with the phytochemical affinities of the genotypes The overall high level of polymorphism and varied range of genetic distances across the genotypes revealed a wide range of genetic base of P tetragonolobus The present investigation therefore, has provided significant insights for further improvement of winged bean germplasm for its qualitative and quantitative traits

Remote Sensing And Image Interpretation

Abstract: Thank you very much for downloading remote sensing and image interpretation. As you may know, people have look hundreds times for their favorite novels like this remote sensing and image interpretation, but end up in malicious downloads. Rather than reading a good book with a cup of tea in the afternoon, instead they are facing with some malicious virus inside their computer. remote sensing and image interpretation is available in our digital library an online access to it is set as public so you can get it instantly. Our book servers spans in multiple countries, allowing you to get the most less latency time to download any of our books like this one. Merely said, the remote sensing and image interpretation is universally compatible with any devices to read.

Drought-Induced Reduction in Global Terrestrial Net Primary Production from 2000 Through 2009

Abstract: Terrestrial net primary production (NPP) quantifies the amount of atmospheric carbon fixed by plants and accumulated as biomass. Previous studies have shown that climate constraints were relaxing with increasing temperature and solar radiation, allowing an upward trend in NPP from 1982 through 1999. The past decade (2000 to 2009) has been the warmest since instrumental measurements began, which could imply continued increases in NPP; however, our estimates suggest a reduction in the global NPP of 0.55 petagrams of carbon. Large-scale droughts have reduced regional NPP, and a drying trend in the Southern Hemisphere has decreased NPP in that area, counteracting the increased NPP over the Northern Hemisphere. A continued decline in NPP would not only weaken the terrestrial carbon sink, but it would also intensify future competition between food demand and proposed biofuel production.

Climate Change 1995

Abstract: Climate Change 1995 is a scientific assessment that was generated by more than 1 000 contributors from over 50 nations. It was jointly co-ordinated through two international agencies; the World Meteorological Organization and the United Nations Environment Programme. The assessment was completed by the Intergovernmental Panel on Climate Change (IPCC) with a primary aim of reviewing the current state of knowledge concerning the impacts of climate change on physical and ecological systems, human health, and socioeconomic factors. The second aim was to review the available information on the technical and economic feasibility of the potential mitigation and adaptation strategies.
