Meeting this formidable challenge requires a substantial effort under climate change impact, economic development and population growth. <strong>International Journal of Environment and Climate Change (ISSN:&nbsp;2581-8627)</strong> aims to publish original research articles, review articles and short communications. This is a quality controlled, double blind peer-reviewed, open access INTERNATIONAL journal. It has long been recognized that the long-term viability of natural capital is critical for many areas of human endeavour under climate change impact. The aims are to support engineering science research with the goal of promoting sustainable development with environmentally benign engineered systems that support human well-being and that are also compatible with sustaining natural (environmental) systems.</p> http://journalijecc.com/index.php/IJECC/article/view/30183 Growth, Yield, Seed and Seedling Quality Parameters of Rapeseed-mustard Varieties under Different Seed Priming Options 2020-04-05T12:40:35+00:00 Rupa Das das.rupa@bckv.edu.in Saikat Biswas Utpal Biswas Amitava Dutta <p><strong>Rationale:</strong> Crop production and quality of produce get affected by drought, stand establishment and low availability of nutrients. Apart from various prevailing methods, seed treatment through priming now-a-days has been found to noticeably improve crop establishment for increasing seed yield and quality.</p> <p><strong>Aim:</strong> To study the effect of various seed priming options on rapeseed-mustard varieties.</p> <p><strong>Place of Study: </strong>A field experiment was conducted at AB Block Farm, Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal, India during winter season of 2017-2018.</p> <p><strong>Methodology:</strong> Experiment comprised six rapeseed-mustard varieties (Anushka, Sanchita, TBM-143,TBM-204, Kranti and Pusa Bold) in main plot and five seed priming options (KH<sub>2</sub>PO<sub>4</sub> @ 0.15 mol 100 ml water<sup>-1</sup> 5 g seeds<sup>-1</sup>, KNO<sub>3</sub> @ 0.1 mol 100 ml water<sup>-1 </sup>5 g seeds<sup>-1</sup><sub>, </sub>PEG 6000 @ -0.3 MPa 100 ml water<sup>-1 </sup>5 g seeds<sup>-1</sup><sub>, </sub>hydro priming @ 100 ml 5 g seeds<sup>-1</sup> and control) in subplot, replicated thrice in a split plot design. Observations on growth and yield contributing parameters were recorded from the field. Further, various quality parameters of seed and seedlings were evaluated in the laboratory. Data on all the parameters were finally statistically analyzed.</p> <p><strong>Results:</strong> Among the varieties, Pusa Bold performed better in terms of growth, yield contributing parameters and seed yield under seed priming through either KH<sub>2</sub>PO<sub>4</sub> @ 0.15 mol 100 ml water<sup>-1 </sup>5 g seeds<sup>-1</sup> or PEG 6000 @ -0.3 MPa 100 ml water<sup>-1 </sup>5 g seeds<sup>-1</sup>. Seed and seedling quality parameters such as root and shoot lengths, seedling fresh and dry weights, germination % and vigour index were also improved under the same.</p> <p><strong>Conclusion:</strong> Cultivation of mustard variety, Pusa Bold by seed priming through any of those two chemicals (KH<sub>2</sub>PO<sub>4</sub> or PEG 6000) can be recommended for New alluvial zone of West Bengal, India.</p> 2020-03-13T00:00:00+00:00 ##submission.copyrightStatement## http://journalijecc.com/index.php/IJECC/article/view/30184 Trend Analysis of Precipitation and Temperature over Different Districts of Karnataka: An Aid to Climate Change Detection and Cropping System Option 2020-04-06T02:59:39+00:00 S. Sridhara sridharas2017@gmail.com Pradeep Gopakkali R. Nandini <p><strong>Aims: </strong>To know the rainfall and temperature trend for all the districts of Karnataka state to develop suitable coping mechanisms for changing weather conditions during the cropping season.</p> <p><strong>Study Design: </strong>The available daily data of rainfall (1971-2011) and minimum and maximum temperature (1971-2007) for each district was collected from NICRA-ICAR website. A non-parametric model such as the Mann-Kendall (MK) test complemented with Sen’s slope estimator was used to determine the magnitude of the trend.</p> <p><strong>Place and Duration of Study: </strong>The rainfall data of 41 years (1971-2011) and temperature data of 37 years (1971-2007) was collected for all 27 districts of Karnataka.</p> <p><strong>Methodology: </strong>Basic statistics related to rainfall like mean, standard deviation (SD), the coefficient of variation (CV) and the percentage contribution to annual rainfall were computed for monthly and season-wise. Mann-Kendall test was used to detect trend for rainfall as well as temperature.</p> <p><strong>Results: </strong>An increasing trend in rainfall during winter, monsoon and annual basis for all most all the districts of Karnataka and decreasing trend of rainfall during pre and post-monsoon season was noticed. An early cessation of rainfall during September month in all most all the districts of Karnataka was observed. Similarly, monthly mean, maximum and the minimum temperature had shown an increasing trend over the past 37 years for all the districts of Karnataka.</p> <p><strong>Conclusion:</strong> The more variation in rainfall during the pre-monsoon season was observed, which is more important for land preparation and other operations. The increasing trend of maximum and minimum temperature throughout the year may often cause a reduction in crop yield. It is necessary to change crops with its short duration varieties in order to avoid late season drought.</p> 2020-04-01T00:00:00+00:00 ##submission.copyrightStatement## http://journalijecc.com/index.php/IJECC/article/view/30185 Climate Change Impacts on Water Quality of Water Bodies-A Review 2020-04-04T08:11:50+00:00 Eliud Salila eliudsalila@gmail.com Mahendra Pal Sharma Rajesh Singh <p>The impacts of climate change on water quality of water bodies are associated with the climatic extreme events (heavy rainfall and flood, heat, drought, wildfires, cyclones, hurricane, super storms) as the major drivers that require knowledge of understanding. Most research studies present the role of climate change in threatening water quality, risks on drinking water and contributions of catchment in water pollution, but less attention has directed to specific sensitive water quality parameters, appropriate methodologies, risks on ecosystem and managerial practice to reduce the impacts. This review highlight the of effect climate change on surface water bodies based on recent literatures on the impacts of climate change on water quality and promote practical opportunity for better management of these impacts. We conclude that consideration of climate change preparedness plan in catchments is the best option to adopt for minimization of climate change impacts on water quality of water bodies.</p> 2020-04-04T00:00:00+00:00 ##submission.copyrightStatement##
