Hisar, India

Chaudhary Charan Singh Haryana Agricultural University is a public funded agricultural university located at Hisar in the Indian state of Haryana. It is one of the biggest agricultural universities in Asia. It is named after India's seventh prime minister, Chaudhary Charan Singh.It was initially a satellite campus of Punjab Agricultural University at Hisar. After formation of Haryana, it was declared as an autonomous institution. It was established as a university by Haryana and Punjab Agricultural Universities Act, ratified 2 February 1970 and was named as Haryana Agricultural University. On 31 October 1991, it was renamed as Chaudhary Charan Singh Haryana Agricultural University. A. L. Fletcher was the first Vice-Chancellor of the university.The university publishes the largest number of research papers among agricultural universities in India. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. It contributed significantly to Green Revolution and White Revolution in India. Wikipedia.

Allelopathy Journal

To make our modern agriculture successful, the use of new agricultural technology in a short span of 35-40 years have caused havoc by contaminating our soil, environment and food with toxic pesticides residues. Modern agriculture is exploitive of growth resources and has caused very serious problems such as environmental pollution through (i). contamination of underground drinking water resources, food and fodder with pesticides and nitrates, which are harmful to human beings and livestock, (ii). poor soil health/ soil Sickness leading to low soil productivity and (iii). poor quality of life. These problems may be overcome with the adoption of Organic Agricultural practices. The definition of Organic Agriculture used in this paper is "Organic Agriculture consists of those practices, which reduces the use of outside inputs viz., fertilizers and pesticides etc on the farm". Therefore, various types of allelopathic strategies may be used for (a) maintenance of soil fertility (use of crop rotations, Biological Nitrogen Fixation, crop mixtures, crop residues and leaf litter etc.), (b) weed management (cover crops, crop residues as mulches, intercropping, crop rotations, phytotoxic or allelopathic varieties and natural herbicides etc.), (c) insects pest management (cropping systems, resistant varieties, insecticidal allelochemicals etc.), (d) nematodes management (plant materials, oilseed cakes, nematicidal compounds etc.), (e) diseases management (cropping systems, crop residues, organic amendments etc.) and (f) use of allelochemicals as growth regulators. Therefore, research efforts are needed to utilise inhibitory allelopathic effects of plants for natural control of crop pests (weeds, insects, nematodes, pathogens), so that use of present pesticides' could be minimized or eliminated for developing Sustainable Organic Agriculture, keeping the environment clean for our future generations and reducing the cost of Organic food.

Biomass and Bioenergy

Rising level of atmospheric CO2 and consequent global warming is evident. Global surface temperature have already increased by 0.8 °C over the 20th century and is projected to increase by 1.4-5.8 °C during the twenty-first century. The global warming will continue till atmospheric concentrations of the major greenhouse gases are stabilized. Among them, CO2 is mainly responsible and is expected to account for about 60% of the warming over the next century. This study reviews advances on causes and consequences of global climate change and its impact on nature and society. Renewable biomass has tremendous potential to mitigate the global warming. Renewable biomass is expected to play a multifunctional role including food production, source of energy and fodder, biodiversity conservation, yield of goods and services to the society as well as mitigation of the impact of climate change. The review highlights the different management and research strategies in forestry, agriculture, agroforestry and grasslands to mitigate the global warming. © 2012 Elsevier Ltd. Source

Journal of Applied Polymer Science

Polyacrylamide gels are widely used as matrices for biomolecular analysis and fractionation, and they are being developed as biomaterials for diverse medical and industrial applications. This study reports silver nitrate as a novel catalyst for the synthesis of polyacrylamide gels from acrylamide and N,N-methylene bisacrylamide monomers. The conditions were defined for silver-catalyzed, free-radical-induced polymerization, and a suitable buffer system was devised for the electrophoretic resolution of nucleic acids. A silver-staining procedure was modified for these gels, and they were compared with N,N,N′,N′-tetramethylethylenediamine-catalyzed gels for sensitivity and gel background. Silver nitrate and ammonium persulfate at final concentrations of 100 and 625 μg/mL, respectively, polymerized the resolving gels within 20 min at room temperature. These gels exhibited antimicrobial properties. The gels with ≥10 μg/mL silver nitrate showed a zone of complete inhibition of Staphylococcus aureus growth on a Luria-Bertani agar plate. The silver-catalyzed gels were also suitable as antigen- and drug-delivery devices. Silver, acting as both a catalyst and a microbicidal agent, was better than N,N,N′,N′-tetramethylethylenediamine for the synthesis of polyacrylamide gels as drug- and oxygen-delivery devices for topical applications. © 2010 Wiley Periodicals, Inc.

Bioresource Technology

The objective of this study was to evaluate changes in physical, chemical and biological parameters to assess the maturity and stability of composts prepared from mixture of different farm and agro-industrial wastes over a period of 150days. All the composts appeared granular, dark grey in color without foul odor and attained an ambient temperature at 120days of composting indicating the stable nature of composts. Correlation analysis showed that the optimal values of the selected parameters for our experimental conditions are as follows: organic matter loss >42%, C:N ratio <15, water soluble organic carbon (C w):organic N (N org) ratio <0.55, humic acid (HA):fulvic acid (FA) ratio >1.9, humification index (HI) >30%, cation exchange capacity (CEC):total organic carbon (TOC) ratio >1.7 and germination index (GI) >70%. Compost enriched with sewage sludge, pressmud and poultry waste matured earlier compared to composts either enriched with distillery effluent or un-enriched. © 2010 Elsevier Ltd. Source

Enzyme Research

Heavy metals are the intrinsic component of the environment with both essential and nonessential types. Their excessive levels pose a threat to plant growth and yield. Also, some heavy metals are toxic to plants even at very low concentrations. The present investigation (a pot experiment) was conducted to determine the affects of varying chromium(VI) levels (0.0, 0.5, 1.0, 2.0, and 4.0 mg chromium(VI) kg - 1 soil in the form of potassium dichromate) on the key enzymes of nitrogen metabolism in clusterbean. Chromium treatment adversely affect nitrogenase, nitrate reductase, nitrite reductase, glutamine synthetase, and glutamate dehydrogenase in various plant organs at different growth stages as specific enzyme activity of these enzymes decreased with an increase in chromium(VI) levels from 0 to 2.0 mg chromium(VI) kg - 1 soil and 4.0 mg chromium(VI) kg - 1 soil was found to be lethal to clusterbean plants. In general, the enzyme activity increased with advancement of growth to reach maximum at flowering stage and thereafter decreased at grain filling stage. © 2014 Punesh Sangwan et al. Source
