Not AvailablePigeonpea (Cajanus cajan (L.) Millsp.) is an important pulse crop grown in rainfed condition in Maharashtra. It is grown mainly as intercrop with sorghum, cotton and soybean. Among different crops grown in rainy (kharif) season, pigeonpea would normally perform better under drought prone condition (Choulwar et al. 2010). However, there is a large variability in the performance of pigeonpea genotypes for grain yield under rainfed condition. Breeding of genotypes thus would require identification of specific attributes that may be transferred to high-yielding cultivars. The present study was undertaken to assess genetic variation of genotypes and identify genotypes for rainfed condition in a semi-arid Vertisol. Twenty three pigeonpea genotypes were tested for yield contributing traits during kharif 2007, 2008 and 2009 under rainfed condition in a semi-arid Vertisol at Marathwada Agricultural University, Parbhani in Maharashtra. Parbhani is located at a latitude of 190 16', longitude of 760 47' and altitude of 409 m above mean sea level. The trials were conducted in a randomized block design with three replications.Not Availabl

Cloud computing in e-Science: research challenges and opportunities

Service-oriented architecture (SOA), workflow, the Semantic Web, and Grid computing are key enabling information technologies in the development of increasingly sophisticated e-Science infrastructures and application platforms. While the emergence of Cloud computing as a new computing paradigm has provided new directions and opportunities for e-Science infrastructure development, it also presents some challenges. Scientific research is increasingly finding that it is difficult to handle “big data” using traditional data processing techniques. Such challenges demonstrate the need for a comprehensive analysis on using the above-mentioned informatics techniques to develop appropriate e-Science infrastructure and platforms in the context of Cloud computing. This survey paper describes recent research advances in applying informatics techniques to facilitate scientific research particularly from the Cloud computing perspective. Our particular contributions include identifying associated research challenges and opportunities, presenting lessons learned, and describing our future vision for applying Cloud computing to e-Science. We believe our research findings can help indicate the future trend of e-Science, and can inform funding and research directions in how to more appropriately employ computing technologies in scientific research. We point out the open research issues hoping to spark new development and innovation in the e-Science field
