International Journal of Environment and Climate Change <p style="text-align: justify;">A sustainable world is one in which human needs are met equitably without sacrificing the ability of future generations to meet their needs and without harm to the environment and ecosystem function and service. 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> SCIENCEDOMAIN international en-US International Journal of Environment and Climate Change 2581-8627 Adoption of Drought Mitigation Strategies in Irrigated Cropping System of Madurai District <p>In drought situation, farmers in Irrigated ecosystem often faced financial losses due to uncertainty of occurrence of drought event. With the intention of minimizing impact of drought through application of science and technology, drought management plans are implemented by government.&nbsp; The outcome of&nbsp;&nbsp; government supported mitigation strategies was studied. The result revealed that only less number of farmer have adopted technological mitigation strategies on their own. Conducting demonstrations, trainings and supply of critical mitigation inputs through development departments must be continued to educate the farmers to adopt the mitigation measures.</p> K.

In semiarid stations, the event of precipitation is occasional and is known something else for its changeability regarding reality. Meteorological drought is characterized as the time of drawn-out dry weather pattern because of underneath ordinary precipitation. Drought is an extensive stretch of incredibly low precipitation that essentially affects crop result and individuals' prosperity. Recent study has made substantial progress in understanding drought in Tamil Nadu, as well as the implications of climate change, but more research is needed because regional climatic responses remain unknown. The Meteorological Drought Indicator was also a useful and appropriate index for drought monitoring in the research area since it provided drought analysis on a variety of timeframes. This study might help us better understand the features of drought.</p> M. Rajavel V. Guhan V. Vakeswaran K. Bhuvaneswari R. Gowtham S.

Viruses have evolved and accompanied mankind from times immemorial but seem to be increasingly threatening the survival of the human race especially in the last four decades. Various theories are available with respect to initial transmissions to humans yet none is endorsed in totality. At the same time climate change poses the greatest threat to human health and its effects are more pronounced in the last four decades than ever before. The purpose of this perspective is to establish scientifically a correlation between the outbreak of COVID-19 or its variants and climate change. This presentation is based on hitherto overlooked yet proven physics and engineering involved in the human respiratory humidification. Respiratory humidification is a uniquely evolved process of Natural Selection to withstand complex and dynamic environments. As COVID-19 is a respiratory viral disease, the gas exchange mechanism and human body’s normal temperature and alveolar air parameters are first explained to justify its uniqueness. A step by step review of physics and engineering involved in respiratory humidification is also done. It is then analyzed in context of Climate Change of a location and its impact on inspired air parameters. Based on Meteorological Data of Wuhan; the place of COVID-19 outbreak; it is established that the Climate Change resulted in redundancy of respiratory humidification and dysfunction of associated immune defence mechanisms of many inhabitants and facilitated viruses like SARS-CoV-2 an unchallenged access to the lungs. The outbreak of COVID-19 and subsequent pandemic was its outcome.</p> Makarand Anand Phadke. B. E.

Among the different classes of cultivated rice varieties, Assam has a distinctive scented rice variety known locally as '<em>joha</em>,' which is particularly popular among the region's farmers. The aroma of <em>joha</em> rice is also thought to differ markedly from that of basmati rice. Genotype stability can be established through genetic variation. Thus, new disease resistant <em>joha</em> rice varieties are necessary to meet both domestic and worldwide demand. There is a need for conservation of this traditional aromatic joha rice germplasm which could be used in the future breeding programme for multiple disease resistance and grain and aroma quality traits improvement. The recent advancements in marker and genomics assisted breeding coupled with high-throughput genotyping and phenotyping enable the discovery of novel alleles and gene targets for the implementation of sustainable rice cultivars with improved grain aroma quality.</p> Nayanmoni Borah Ramendra Nath Sarma Vedant Vikrom Borah Partha Pratim Behera ##submission.copyrightStatement## 2022-05-10 2022-05-10 338 347 10.9734/ijecc/2022/v12i1030805 Safeguarding National Developments against Climate Change: Cost Implications on Sectors, Services and Assets <p>The world has come to terms with the alarming impacts of climate change, and their costs which are both monetary, and non-monetary. Increasing emissions and their global warming bearings, have resulted in disequilibrium of the climate system, and the associated ecosystems. This makes mitigation (low carbon strategies) to be essential. With the current world being on a high carbon trajectory, there is need for transition. A move in the energy sector (away from fossil fuel intensity), building the right financial investments, transitions in the planning (e.g. transform market systems for sustainability), policies and livelihood choices that acknowledge limits to planetary provisions, and, to safeguard humanity. The planet is on an increasingly unfamiliar trajectory, hence uncertainty to support lives as before. However, COP26 and the IPCC 2021 report indicated shortfalls in mitigation ambitions, which are needed to bring the planet back on track. Emissions need to be cut, to realise the Paris Agreement objectives, as well as the Sustainable Development Goals (SDGs), as climate change has far-reaching negative impacts, due to its cross-cutting nature. There are data gaps on the costs of current climate change i.e. the mitigation and adaptation costs, at national levels. The data would enable ease of implementation, build standardisation through agreed tables and formats, for accounting and reporting, and the necessary targets. Thus national plans, policies, technologies, institutional frameworks, business sector response mechanisms, and livelihood choices need to respond, so that the planet remains sustainable. The conclusions of this overview indicate that, national plans, those of private sector and of the citizenry need to escalate sustainability to a higher level. Most impacts of climate change would add to costs of production, heighten risks, and bring more uncertainty as well as negatively disrupting services and industries. The climate action needs to prioritize costs of climate change, to inform action on the Nationally Determined Contributions (NDCs), SDGs, livelihood assets and lead to the building of right investments. These are underlined by partnerships for delivery, governance, data interventions, and inclusion, in a world which is increasingly exhibiting inequalities, and their associated vulnerabilities. All these have mitigation and adaptation costs, which need to be part of Paris Agreement compliance frameworks for Parties/nations.</p> Julius R.

The un-engineered solid waste dumping yard site spreading over about 300 hectares (ha) is located on topographic high (hillock) and falls in Madyala stream and Dammaiguda watersheds of Musi sub-basin. Granites of the Archaean age underlie the area. Both surface and groundwater samples, collected covering hydrological cycles of 2011and 2012, were analyzed for major chemical constituents. Fifteen samples belonging to both seasons of 2012 were tested for BOD, COD, and TOC. The mean values of some tested chemical constituents of surface water samples (15) were - EC 13066 m S/cm, TH 753, Na<sup>+</sup> 813, K<sup>+</sup> 530, HCO<sub>3</sub><sup>-</sup> 978, Cl<sup>-</sup> 1304, and NO<sub>3</sub><sup>-</sup> 262 (all in mg/l), which prove that tanks and stream near the dump yard were pools of leachate. The average values of contaminated groundwater samples among the four sampled sessions (17) indicate EC was above 5000 m S/cm, TH 1624, Cl<sup>-</sup> 1502, and SO<sub>4</sub><sup>2- </sup>284(all in mg/l), which were found much above the threshold values. Very high TOC (mean SW 241; GW 154 mg/l), BOD (5410; 117), and COD (6427; 176) content in both surface (SW) and groundwater (GW) samples indicate the presence of organic pollutants sourced from domestic waste dumps. Wide temporal and spatial variability in the concentration of many ion species could be due to rainfall deviation, point source changes, and heterogeneous fracture patterns. Low resistivity values (5 to 25 ohm.m) at a distance of 4 km from the dumping site and high infiltration rate (29 cm/hr) at the Madyala stream indicate hydrological features controlled the mass flux. The chloride-sulphate alkaline-earth water facies, K<sup>+</sup>:Mg<sup>2+ </sup>and BOD/COD ratios demonstrate apart from anthropogenic input water-rock interaction and evapotranspiration governed the evolution of water chemistry. The study supports the hypothesis that solid waste dumps, which attained the methanogenic phase, were a point source of pollution that generates leachate and dissipates contaminants to the aquatic environment through preferred pathways influenced by factors like soils, topography, aquifer hydraulics, and contaminant kinetics.</p> P.

If we are not able to safeguard the lives of those who protect us, then is palpable that our lives are also at stake exclusively in a period where there are so many genetic adversaries to combat so as to maintain, inspire and protect the lives of the individuals. To shield ourselves from environmental diseases, the welfare of sanitary workers is of overriding prominence.</p> <p><strong>Aim:</strong> The study aimed at reconnoitering occupational health and safety practices of sanitation workers of University of Education, Winneba, (UEW) Ghana.</p> <p><strong>Place and Duration of Study: </strong>The study took place at University of Education, Winneba campus in the Effutu Municipality in the Central Region of Ghana, between May, 2021 and January, 2022.</p> <p><strong>Methods:</strong> The study employed a qualitative approach with a case study design in investigating occupational health and safety (OHS) practices among sanitation workers in UEW. A purposive sampling method was used to recruit the respondents for the study with a focus group discussion guide and in-depth interview guide as the main instruments for data collection. Data were analysed qualitatively using the content analysis technique.</p> <p><strong>Results:</strong> The findings of the study revealed four indices that embodied and affected the working conditions of sanitation workers. These included: occupational stress; hazardous conditions; remuneration; and job security. Again, it was also revealed that there was inadequate personal protective equipment (PPEs) supplied by the university management and poor use of PPEs with the most used PPEs being nose masks by the sanitation workers as a result of the enforcement of Covid-19 protocols. Major challenges faced by the sanitation workers in adhering to OHS practices were found to be poor remuneration, inadequate tools/equipment, poor supervision, unfavourable weather condition and abuse as well as assault.</p> <p><strong>Conclusion: </strong>The well-being of every individual matters, if there is a poor condition of service and poor adherence to OHS practices by sanitary workers in an institution of higher education then worse cases or scenarios may be bound to happen elsewhere. There is therefore the need for relevant stakeholders to stand and advocate for proper formulation and enforcement of OHS protocols as well as ensuring good working conditions for all.</p> Charles Owusu-Aduomi Botchwey Dennis Kesseh Michael Afari Baidoo Agartha Afful Boateng Dorothy Serwaa Boakye ##submission.copyrightStatement## 2022-05-04 2022-05-04 226 237 10.9734/ijecc/2022/v12i1030789 Screening of Exotic Collections of Arabica Coffee Genotypes for Coffee Berry Borer and Coffee Leaf Rust Disease Incidence <p>In India, commercial cultivation of coffee relies upon two important species like <em>Coffea arabica</em> (Arabica coffee) and <em>Coffea canephora </em>(Robusta coffee). In the consumer market, arabica coffee is preferred for its fine beverage quality, aromatic characteristics and low caffeine content compared to robusta coffee. In India coffee is grown under natural agroecosystem offers arabica coffee to fetch premium price in the international market. In spite of the commercial importance and the appropriate environmental conditions, the drastic reduction of arabica coffee area in India is likely associated with lack of adaptability for each ecological zone of the region, susceptibility to coffee berry borer and leaf rust and increased cost of production coupled with low productivity (470 kg clean coffee/ha). Therefore to address the issues identification of resistance source is the important criteria in crop improvement programme. With this background the study was aimed at screening of exotic collections of Arabica coffee genotypes maintained at Central Coffee Research Institute (CCRI), Balehonnur, Karnataka, India against Coffee Berry Borer (CBB) and Coffee Leaf Rust (CLR). The experiment was laid out randomized block design with three replications. Results revealed that, the CLR disease severity infection was ranged from 1.34 to 32.67 per cent and the genotypes S.1495, S.1561, S.2504, S.2509, S.2510, S.2529, S.2602 and S.2724 exhibited moderately resistant to leaf rust disease infection based on mean per cent disease severity level (1-5%). Hence, these genotypes will be valuable as new sources of resistance to these pathogens in the future and can be utilized in coffee breeding programmes in India. Similarly, all the genotypes utilized in the study were established low to least infestation of coffee berry borer (1.03 to 5.03 %).</p> Nagaraj Gokavi P. M. Gangadharappa N. S. Prakash J. S.

Potential evapotranspiration (PET), rainfall, water deficit and moisture index trends were analyzed for 30 years (1988-2018). PET was computed by using Modified Penman-Monteith method as recommended by FAO. It concludes that though the amount of mean annual rainfall is moreover same but the variation in duration and distribution exists. The analysis shows that number of rainy days has decreased in this long period, which led to increase the PET. High water deficit resulted in shifting of bio-climate towards arid condition. The results indicates that Maximum mean annual rainfall was observed in Mahabaleswar station of Maharashtra (6098 mm) and minimum mean annual rainfall also reported in Malegaon (545 mm) of Maharashtra, in Central India. It was observed that western districts of Madhya Pradesh (Barwani, Alirajpur) are shifting significantly towards drier side during the period of 30 years.

A study was conducted during <em>kharif </em>2018 to evaluate the relationship between grain yield and its components in pearl millet using correlation and path analysis studies. In the current study, significant genotypic and phenotypic correlations were found among five yield contributing traits in eighteen pearl millet hybrids. The traits including days to 50% flowering, plant height, and panicle length were found to have positive correlation with grain yield per plant that implied the importance of those traits in selection of high yielding hybrids. Grain yield per plant was used as a dependent character in path-coefficient analysis at the genotypic level. Plant height and panicle length were the independent variables (cm). The highest positive and direct effect was found for days to 50 percent flowering (0.9946) followed by panicle diameter (cm) (0.5726). Pearl millet having deep root system are often found to survive even in various stressful conditions including water stress. These characteristics have made it popular in dry and semi-arid regions around the world; nevertheless, compared to other major cereals, less work has been put into the study of climate-resilient characteristics of pearl millet.

In this study, we assessed the effects of both land use and predicted climate change on the Arpa Catchment water yield using the ArcSWAT model. The influence of changing climate on water yield was evaluated for different emission scenarios using CMIP6 Global Climate Models (GCM). Three GCM namely BCC-CSM2- MR, EC-Earth3-Veg and NorESM2-LM were ensemble and used for this study. Two ‘Shared Socioeconomic Pathways’ (SSP) scenarios (SSP.2_4.5, and SSP.5_8.5) were used for future climate prediction in the current study area. Land use land cover, meteorology and soil type data used as inputs to analyze the spatial and temporal pattern of water yield in the Arpa catchment from 1990 to 2020 and the impact of land use change on water yield in the basin simulated with ArcSWAT Model. Water yield compare to baseline scenario (1990) increased by 98.36 mm (18.48%) in decadal year 2000, increased by 144.51 mm (27.15%) in year 2010 and in decadal year 2020 water yield increased by 154.20 mm (28.98%). Climatic scenario (SSP2_4.5 and SSP5_8.5) changes in water components were simulated with ArcSWAT model. Model was run for three future time slices i.e. Near future (2030s), Mid future (2060s), and Far future (2090s). Water yield with reference to baseline period (646.02 mm) increased by 71.69% under SSP2_4.5 during 2090s. Similarly, under SSP5_8.5 water yield increased by 106.87% for the far future (2090s).</p> Shruti Verma Dhiraj Khalkho M. P.

Cytoplasmic male genetic sterility system is a valuable technology for exploitation of heterosis and production of high yielding hybrid rice with better grain quality. A total of forty rice genotypes comprising 20 maintainer and 20 restorer lines were evaluated to study the variability and correlation between floral, yield and yield contributing traits. High significant variation was observed among the genotypes for all the studied traits. Number of grains per panicle, 1000 grain weight and duration of spikelet opening recorded high GCV values and high heritability coupled with high genetic advance which indicated the broad genetic base, less environmental influence and these traits are under control of additive gene action. The correlation analysis among the traits were further studied. The duration of spikelet opening, plant height, number of productive tillers, stigma breadth expressed positive significant association along with positive direct effect on grain yield per plant indicated that selection for these traits will be effective in varietal development programme as well as exploring the gene pool.</p> T.

Genotypes do not show the same response in all locations due to their interactions with the surrounding environment. Such interactions limit the breeding progress during the selection of superior genotypes. Multi-location trials are being carried out to study the behavior of genotypes in different environments. Genotype environment interaction is a major problem in selecting and recommending superior genotypes to cultivate crops. When we are dealing with perennial crops like Mango, this problem gets intensified because choosing unstable cultivars to plant in an orchard puts the farmers in a risky income situation for many years. In the present investigation, an attempt has been made to identify the high-yielding and stable genotypes of Mango by using AMMI stability measures. Data on sixteen genotypes of Mango tested across four locations viz., Rewa, Sabour, Sangareddy, and Vengurla in India over nine years is considered for the study. The present study concludes that the AMMI stability measures SIPC, AVAMGE, ASTAB, DA, MASV, MASI, ZA, ASV, and ASI are based on the biological concept of stability, and the stability measures DZ and EV are based on the agronomic concept of stability. Selection of mango genotypes based on the agronomic concept of stability will be recommended in favorable environments, while selection based on biological stability will be advised in unfavorable environments.</p> K.

This paper focused on study on level of awareness of the respondents about agri waste management practices and its relationship with the profile of the farmers.. The Ex-post facto research design was adopted for the study. Thus a total of 120 respondents were selected by following simple random sampling method covering Medak district of Telangana state. From the analysis,it was found that majority of the farmers (55.00%) had high level of awareness, followed by medium (27.50%), and low (17.50%) level of awareness about agri waste management practices. From the analysis, it was found that infrastructure facilities and achievement motivation had positive and significant relationship with awareness at one percent level of significance. The variables age, education, farm size, farming experience, cropping pattern, innovativeness, information seeking behavior and training undergone had positive and significant relationship with awareness at five per cent level of significance. However cropping intensity and level of aspiration had positive and non-significant relationship with level of awareness about agri waste management practices. Government should provide subsidy on the purchase of machinery, special programmes need be to taken to improve awareness about agri waste management and encourage custom hiring centers to reach high cost technologies to the farners.

Rice is one of the important food crops to get affected by the low water availability because of its high water requirement. Various techniques were used in the past to mitigate low water availability and increase productivity but most techniques will improve one aspect at the expense of the other. System of Rice Intensification (SRI) is being tried by many countries with several modifications based on their priorities, with the aim of enhancing productivity besides reducing the water demand for rice cultivation.&nbsp; It is essential to have more insight into the individual and compounding effect of multiple components of SRI on yield, and water productivity of rice for identifying the potential and suitable SRI practices. Investigating the influence of different practices of SRI viz., planting of young and single seedlings per hill in wider spacing, water saving irrigation like Alternate Wetting and Drying (AWD), and weed control using cono-weeders on rice using the data obtained from the field experiment carried out during 2021 in Tamil Nadu Agricultural University, Coimbatore, India. Water productivity of rice plants under SRI were compared with conventional practices. The results revealed that plants grown with complete SRI practices had increased water productivity by 0.25 kg grain/m<sup>3 </sup>of water which is almost twice that of conventional cultivation system. The yield obtained in SRI treatments was higher about 39% than conventional treatments. The total water savings were 20 % higher in AWD treatments than continuous flooding treatments.</p> <div id="urban_overlay">&nbsp;</div> <div id="urban_overlay" style="left: -10px; top: -10px; width: 0px; height: 0px;">&nbsp;</div> Jeevanand Palanisamy V.

The 45 hybrids along with their 18 parents and two check cultivars were evaluated in three environments <em>viz.,</em> E1 (<em>Kharif</em>-2019, Instructional Farm, RCA, Udaipur), E2 (<em>Kharif</em> -2019, Agriculture Research Sub-Station, Vallabhnagar, Udaipur) and E3 (<em>Rabi</em>-2019-2020, Instructional Farm, RCA, Udaipur) in randomized block design with three replications at each environment to assess the phenotypic stability of genotypes by using Eberhart and Russel (1968). The mean squares due to genotypes and environments were found significant for all the traits under study indicated inherent genetic differences among the genotypes. The G x E (linear) interaction was found significant for most of the traits under study The mean squares due to pooled deviation were found non-significant for all the traits indicated major portion of the genotype x environment interaction was formed by predictable portion. The majority of the hybrids depicted non-significant deviations from regression (S<sup>2</sup>d<sub>i</sub>) for grain yield per plant indicated their predictable response across the environments. A great majority of genotypes revealed non-significant non-linear estimates (S<sup>2</sup>d<sub>i</sub>) for different traits under the study indicated the prediction of stability was more or less accurate and reliable.

Rice–maize double cropping is gaining popularity in many Asian countries including India. fertilizer need of a crop in a system is strongly influenced by the preceding crops and the amount of fertilizers applied to them. Cropping with two nutrient intensive cereals like rice-maize would remove a substantial quantity of plant nutrients from soil during continued agriculture round the year, envisaging the need for adoption of efficient nutrient management practices for sustained soil health and improving system productivity. A field experimentt was carried out to study the residual effect of organic nutrient sources and inorganic fertilizer levels on yield attributes and yield of zero till maize. The experiment was laid out in split plot design with four organic sources of nutrients applied to preceding rice as main plots <em>viz</em>: M<sub>1: </sub>Neem leaf manure @ 6 t ha<sup>-1</sup>; M<sub>2</sub>: Vermicompost @ 2 t ha<sup>-1</sup>; M<sub>3</sub>: Goat manure @ 5 t ha<sup>-1</sup>; M<sub>4</sub>: Microbial consortia [seed treatment @ 4 g kg<sup>-1</sup> + soil application @ 4 kg ha<sup>-1</sup>] and four subplots with graded doses of fertilizers <em>viz</em>: S<sub>1</sub>: Control; S<sub>2</sub>: 50% RDF; S<sub>3</sub>: 75% RDF and S<sub>4</sub>: 100% RDF (180:60:60). The study revealed that various organic nutrient sources and graded fertilizer doses exerted a remarkable effect on plant height, LAI, dry matter production and Days to 50% silking which resulted in significantly higher grain, stover yield and harvest index of zero till maize.</p> J.

For many important agricultural areas groundwater is the ultimate source of fresh water as surface water sources have been depleted. The quality of groundwater is important because it determines the suitability of water for drinking, and domestic and irrigation purposes. A survey was undertaken during the year 2020 to assess the quality of groundwater for irrigation in Mondipatti region of Tiruchirapalli district of Tamil Nadu. A totally 18 samples were collected from bench mark wells of (W1-W18) in and around the paper board industry and GPS locations of sampling points were recorded. The water samples were analyzed for various chemical properties <em>viz., </em>pH, EC, Ca<sup>2+</sup>, Mg<sup>2+</sup>, Na<sup>+</sup> and K<sup>+</sup>; CO<sub>3</sub><sup>2-</sup>, HCO<sub>3</sub><sup>-</sup>, Cl<sup>-</sup> and SO<sub>4</sub><sup>2-</sup>. The pH, EC, SAR and RSC in groundwater ranged from 7.6-8.4, 0.68-5.12 (dS m<sup>-1</sup>), 0.69-12.9 and -8.1 to 5.3 (meq L<sup>-1</sup>), respectively. The concentration of cations <em>viz., </em>Ca<sup>2+</sup>, Mg<sup>2+</sup>, K<sup>+</sup> and Na<sup>+</sup> varied from 1.7 to 10.8, 0.7 to 14.3, 0.009 to 0.931 and 2.8 to 39.2 meq L<sup>-1</sup> with average of 5.4, 4.51, 0.190 and 9.24 meq L<sup>-1</sup>, respectively. The concentration of anions <em>viz., </em>carbonate, bicarbonates, chloride and sulphate varied from nil to 3.2, 3.2 to 9.6, 2.8 to 39.2 and 0.25 to 4.52 meq L<sup>-1</sup> with average values of 0.64, 6.72, 11.88 and 1.31 meq L<sup>-1</sup>, respectively. The relative abundance of ions for most of the water samples were Na<sup>+</sup> &gt; Ca<sup>2+</sup> &gt; Mg<sup>2+</sup> &gt; K<sup>+</sup> for cations and Cl<sup>-</sup> &gt; HCO<sub>3</sub><sup>-</sup>&gt; SO<sub>4</sub><sup>2-</sup> &gt; CO<sub>3</sub><sup>-</sup> for anions. According to CSSRI water quality classification, 44.5, 44.5, 5.5 and 5.5 per cent of good, marginally saline, High SAR saline and Alkaline, respectively. Spatial variability maps of pH, EC, SAR and RSC of groundwater used for irrigation in and surrounding areas of paper board industry were also generated. As a result, it's critical to analyse groundwater quality not only for current use, but also as a future water source. Assessment and mapping of quality of groundwater may help the farmers in choice of crops and other agronomic management practices for getting profitable yields without affecting the soil health.</p> S.

In this context a survey was conducted in three districts i.e., Coochbehar, Alipurduar and Jalpaiguri districts of northern tracts of West Bengal to find the diversity of species of pulse beetle and its species abundance in stored chickpea during 2018-2020. In the collected chickpea seed samples, four species namely, <em>Callosobruchus chinensis</em> L., <em>C. maculatus </em>F., <em>C. analis</em> L. and <em>Callosobruchus </em>sp. (indet) unknown were observed. Coochbehar districts had highest diversity with species evenness (0.49), Brillouin index (1.17), Simpsons index (0.68), Shannon index (1.23), Hill index (0.49) and effective diversity (3.43) followed by Jalpaiguri with Species evenness (0.46), Brillouin index (1.04), Simpson index (0.64), Shannon index (1.09), hill index (0.48) and Effective diversity (2.99). Alipurduar district found lowest species diversity indices. Community structure of <em>Callosobruchus</em> spp. in three districts follows Null model which found as best fit model.

Morphometric analysis of the Nanjannad watershed is carried out using integrated approach of remote sensing and GIS techniques. The present study attempted to determine the morphometric characteristics of Nanjannad watershed of Ooty, Tamil Nadu. Geographical information system (GIS) is used to evaluate linear, areal and relief aspects of morphometric parameters. The drainage area of the watershed is 434 ha, the watershed is a Fourth-order drainage basin, and the lower order streams are mostly dominating in the watershed. Physiography, rainfall and lithology of the location control the stream orders. The development of stream segments in the watershed area is affected by rain, slope of the watershed varies from 0 to 87%. The mean R<sub>b </sub>of the entire watershed is 4.38, indicating that geological structures do not influence the drainage pattern much. The whole watershed elongation ratio is 0.67 showing the majority of the area has Moderate relief and a steep slope, Relief ratio values implies that the discharge of the Nanjannad watershed is high and groundwater potential is meager, the moderate value of drainage density, stream frequency and drainage intensity, indicates that runoff is more likely to cause water logging. This work can be used as input to evaluate hydrology and water resources and will be helpful for integrated watershed planning.</p> Gangannagari Karthik K. Nagarajan S. Manivannan Balaji Kannan M. R.

Throughout its growth period wheat crop requires varying degrees of temperature to achieve ideal growth. Any variation from optimal temperature adversely affects plant growth and development. Many places where wheat is grown have high temperatures at the time of grain filling which is a major constraint on yield potential. A field experiment was conducted during the Rabi season of 2020-21 at Student’s Instructional Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya, Uttar Pradesh to evaluate the performance of wheat varieties under heat stress conditions. The treatment for the experiment consisted of sowing on three different dates i.e. D<sub>1</sub> (30<sup>th </sup>November), D<sub>2</sub> (15<sup>th</sup> December), D<sub>3</sub> (30<sup>th</sup> December). It was observed that time of sowing decreased substantially almost all the yield components measured <em>viz</em>; number of ear bearing tillers per plant, number of grains per ear, ear length (cm), grain yield per plant (g), biological yield per plant (g), which caused severe reduction of yield in V<sub>1</sub> (PBW-343) and V<sub>2</sub> (HD-2967). This reduction was caused due to onset of high temperature during crop growth and particularly grain filling. Variety V<sub>3</sub> (Halna) reduced the detrimental effect of heat stress by improving physiological traits which ultimately helped in obtaining higher yield.</p> Lavkush, Alok Kumar Singh Shraddha Singh Deeksha Tiwari Piyusha Singh Syed Tazeen Zaidi R.

This zone has increasingly undergone significant climate change in recent decades. The main consequence of this climatic phenomenon is the decline in the standard of living of rural communities whose main economic activity is agriculture. This research aims not only at investigating the variations that characterize the climate but also at analyzing the impact on agricultural production at the scale of the research site. The data of certain climatic parameters such as Rainfall, temperature and evapotranspiration from the period 1981-2020 were used in order to achieve the objective of the study. The Standardized Precipitation Indices (SPI), the Martonne aridity indices, the Lamb index and the Pettit test are the statistical treatments used to describe the hydro-climatic manifestations of the research area. The results from the various statistical processing of climate data show that the lower Zio valley is undergoing more or less significant climate changes with an upward trend in cumulative rainfall. The standardized index made it possible to highlight the rainfall variations characterized by the alternation of surplus and deficit years. Indeed, the years of increased rainfall are for example: 1999 with 30.27% water surplus; 2010 with 27.2% and 2017 with 22.99%. On the other hand, some of the deficit years are 1983 with 34.70% of deficits; 1992 with -36.98% and 2000 with -34.70%. In addition, the low temperature differences are 1.05°C in Lomé and 0.59°C in Tabligbo. In the end, all these climatic phenomena disrupt the normal course of crop development cycles and provoke lower agricultural yields.</p> Lemou Faya ##submission.copyrightStatement## 2022-05-19 2022-05-19 555 563 10.9734/ijecc/2022/v12i1030830 Effect of Plant Growth Regulators at Different Levels of Zinc on Growth and Yield of Groundnut (Arachis hypogea L.) <p>The field experiment entitled “Effect of Plant Growth Regulator at different levels of Zinc on growth and yield of Groundnut <em>(Arachis hypogea </em>L.)”&nbsp; was conducted during <em>kharif </em>season of 2021 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P).

Data were collected from 125 farmers from five tribal hamlets of Deverkonda mandal of Nalgonda district of Telangana state. The major constraints reported by almost all the farmers (99.2%) were financial problems primarily due to loss of wage work, repayment of informal loans (83%), fear of contracting COVID-19 (92%) and health of family members (89%) which adversely affected their work efficiency. Paddy crop was the most affected as rated by 80.8% of the farmers, followed by vegetables 52.8%, groundnut 41.6%, cotton 37.6%, redgram 16.8% and fruit crops(sweet lime) 13.6% respectively. The farmers faced problems in land preparation (92.8%), high cost of inputs (96.8%), and low availability of inputs (75.2%), transport problems to procure inputs (96.8%), labour shortage (67.2%) and storage of unsold produce (75.2%). Shortage of animal feed (79.2%) and health care of animals (85.6%) were the constraints faced in livestock care. The harvesting of paddy was the most affected due to shortage of labour and harvesting machines. Community seed and animal feed banks, collectives like farmer producer organizations, collateral free credit, small packaging of inputs, promotion of youth entrepreneurship in processing storage and sale of produce and mechanization of small farms, direct procurement, logistic support are some of the immediate and mid- term measures being suggested for building resilience of food systems to face future risks.</p> Amtul Waris Battu Jangaiah Jana Harish ##submission.copyrightStatement## 2022-04-27 2022-04-27 688 695 10.9734/ijecc/2022/v12i1030851 Determination of Maize (Zea mays L.)

Crop loss can be minimized by making adjustment through timely and accurate weather forecasting. Hence, there is necessity to validate the coming five days rainfall forecast analysis to determine the accuracy skill for managing strategic decisions by farmers. For validation of rainfall forecast qualitative and quantitative verification methods were adopted by India Meteorological Department, New Delhi. In these results, validation of qualitative and quantitative verification methods for southwest and northeast monsoon, 2021 indicated that high skill score for all ASD (agro sub divisional) level and moderate skill score for Khammam district level. A survey was conducted randomly for 230 farmers during year 2021-22 for reviewing effectiveness of agromet advisory services (AAS). The results indicated that most of farmers have been following AAS and checking weather forecast for post harvest operations like sowing / transplanting, harvesting / threshing, pesticide application, irrigation application, fertilizer application and other farm operations. It was observed from survey that 60.4 % of respondents rated AAS as highly satisfactory service.&nbsp;</p> Nagaraju Dharavath J. Hemantha Kumar W. Jessie Suneetha K. Ravi Kumar V. Chaitanya P. S. M.

Different meteorological drought indices are normally used to determine drought, which are essentially constant functions of rainfall and hydro-meteorological factors. A universal drought index cannot be used to evaluate the severity of drought in a specific region due to the essential difficulty of drought phenomena, hydro-climatic factors, and watershed characteristics. Classifying an appropriate drought index requires evaluating the performance of various drought indices. This study evaluated 5 meteorological drought indices for Gujarat, India utilizing a dataset from a total of 167 raingauge and climate stations having over 30 years (1986-2015 of the dataset). In various countries, several droughts indices have been introduced and utilized. This study evaluates the effectiveness of 5 meteorological drought monitoring indices in Gujarat. The following meteorological drought indexes were chosen based on data availability: Standardized Precipitation Index (SPI), Standardized Precipitation Evapotranspiration Index (SPEI), Percent Departure from Normal (PDN), Effective Drought Index (EDI), and Reconnaissance Drought Index (RDI). The EDI is a time step independent drought indicator, with 1-, 3-, 6-, 9-, and 12-month time intervals defined for the four multi-time scale indices. This drought index was compared using several time scales of multi-time scale drought indices based on their association with the EDI. The evaluation of drought indices during the historic drought was assessed based on the occurrence and response of drought indices within the specific drought severity classes. In the present study area, the 9-month scale is suitable for comparisons of drought indices. The SPEI-9 had the highest relative occurrence in the 'severe dry' class, and it was subtle to 9-monthly rainfall in most districts. As a result of the study, SPEI-9 is considered the best drought index.</p> Bhukya Srinivas Mukesh Kumar Tiwari Gautam R.

Multiple regression analysis revealed that temperature has a negative effect and rainfall and relative humidity have a positive effect on egg production in India. Decomposition of prices of eggs to trend, seasonal, cyclical and irregular components was done using Minitab. The data on egg prices from June 2009 to May 2022 was obtained from National Egg Coordination Committee (NECC) website. Bengaluru, Chennai, Delhi and Mumbai are the four markets considered for the study. The average price per 100 eggs is highest in Mumbai (Rs.366.06) followed by Chennai (Rs.360.25), Bengaluru (Rs.348.52) and Delhi (Rs.341.17). the prices of eggs showed wide fluctuations and there is uniformity in prices of eggs across all the selected markets due to organized egg marketing. The prices of eggs in all the selected markets showed a highly significant increasing trend. The annual increase in egg prices was highest in the Mumbai market (Rs.1.57/100 eggs) and lowest in the Delhi market (Rs.1.35/100 eggs). The highest seasonal index was observed during the month of June in Bengaluru and Chennai markets and during the month of July in Delhi and Mumbai markets. In the month of April, the prices of eggs decreased due to their short shelf life because of summer whereas in the month of November the prices of eggs decreased due to an increase in arrivals of eggs. The highest price of eggs during the June and July months is due to an increase in the consumption of eggs. Egg prices do not have any price cycles and irregular variations are observed for all the markets considered under study. Government should take initiative to educate poultry farmers regarding the impact of climate change on egg production as well as prevailing egg prices in the market.</p> P.

The basic objective of the sowing operation is to put the seed in rows at the desired depth and maintain seed to seed spacing, covering the seeds with soil and providing proper compaction over the seed. Early or postponed sowing adversely disturbs the crop yield. Therefore, the sowing of seeds in the optimum level is important to ensure more outcomes and high quality of crops. At present, the maize planting is done manually by broadcasting, dibbling, putting seed behind the plough, and other methods or with the help of animal or tractor-drawn seed drills/planters. Though, these techniques have many problems, such as worse efficiency and reduced quality seed placement. Currently among different sowing methods, dibbler planter delivers more uniform and adaptable seed spacing than other approaches for sowing hybrid seeds. But available dibbler planter has some shortcomings of lower field capacity. By considering the apparent advantage of the dibbler planter mechanism, the power-operated dibbler planter for pulse crop was modified and improved to minimize the problems of the existing dibbler planter. Henceforth, the two-row power-operated dibbler was designed and developed to promote mechanization of maize planting operation among small and marginal farmers.</p> P. K. Padmanathan Govind Meena S.

It is the basic information for analysing the changes in the environment. Therefore it is important to monitor water resources accurately. Nowadays remote sensing plays a major role in extraction of water spread area. In this study, change in water spread area of tanks was mapped for Coimbatore corporation from 2000 to 2021. The analysis was performed in Google earth engine platform using Landsat ETM+ and Landsat OLI datasets. The images for pre monsoon and post monsoon season were scrutinized and classified using random forest classifier in Google earth engine. The area of each tanks and their deviations were calculated for the study period. Results of the study showed that the lowest water spread area was observed in the period from 2000 to 2005 for both pre monsoon and post monsoon season. The tank has maximum water spread area during post monsoon season. The difficulties that has been confronted during the research is the unavailability of images due to cloud cover. The study shows that the random forest classifier can be effectively used to extract water features and water spread area.</p> M. Akshaya Balaji Kannan G. Thiyagarajan R.

Genotypes for their Germination and early Seedling Parameters Grown Under Different Saline levels <p>Seedling establishment is a most critical stage that determined the crop production at later stages. An <em>in vitro </em>investigation was carried out at the Laboratory of the Department of Plant Breeding and Genetics, Sri Karan Narendra College of Agriculture, Jobner (Rajasthan) in <em>Rabi </em>season 2016-17 to study the response of fenugreek genotypes for their germination and early seedling parameters under five salt stress levels <em>viz.</em> 0.0 mM, 40 mM, 80 mM, 120 mM and 160 mM. Fifteen seeds of each genotype were sown in sterilized Petridish and seedling observations were recorded. Results revealed that the average value was found maximum in the control and minimum at higher salinity level for most of traits. Higher reduction was found at higher salinity levels for most of the characters viz., plumule length, radicle length, seedling length, plumule to radicle length ratio, plumule fresh weight, radicle fresh weight, plumule dry weight, radicle dry weight and seedling vigour index but germination percentage showed less reduction. The contrast between mean of various genotypes in control&nbsp; conditions (S<sub>0</sub>) versus S<sub>m</sub> (mean of S<sub>1</sub>, S<sub>2</sub>, S<sub>3</sub> and S<sub>4</sub>) for each character also showed that overall mean was highest in control as compared to the overall mean of salinity levels for all the traits. This investigation concluded that higher level of salinity (above 60 mM) adversely most affected to seed germination and other early seeding traits rather than (below 40 mM) lower salinity levels. Based upon the rank totals of genotype over different salinity levels S<sub>1</sub>, S<sub>2</sub>, S<sub>3</sub> and S<sub>4</sub> (S<sub>m</sub>) and characters, the RMt-303 was found to be most desirable genotype followed by UM-385, RMt-143 and RMt-305.

In this context, the growing of drought-tolerant genotypes which are adaptable to water-limited conditions is the need of the hour. With this view, front-line demonstrations were conducted to popularise the variety (SPV 2217) in the Suntnoor village of Aland taluka, Kalaburagi District. The results of front-line demonstrations indicated a higher yield (22.75 q/ha) of SPV 2217 as compared to the local variety (19.10 q/ha) due to the maintenance of greenness at physiological maturity. Due to higher yield, higher income was obtained and that led to a higher B:C ratio (2.42) as compared to the local variety (2.06).

For the years 2018 and 2021, the Optical Characteristics of Aerosols and Clouds (OPAC) model was used to estimate monthly, seasonal, and spectral variations of aerosol optical properties such as Aerosol Optical Depth (AOD), Single Scattering Albedo (SSA), and Asymmetry Parameter (ASY). The dominance of fine anthropogenic aerosols was shown by higher AOD during the pre-monsoon period. The maximum and minimum seasonal variation of AOD occurred during pre-monsoon (1.1 ± 0.02) and winter (0.21 ± 0.001) respectively. The significant spectral variation of AOD occurred during March to May as it decreases with the increase in wavelength .The SSA increases as the wavelength increases, ranged between 0.83 ± 0.02 and 0.77 ± 0.01.The variability of SSA is significant during January and February which is a characteristic of coarse type aerosols. Asymmetry Parameter with the monthly mean of 0.75 ± 0.01 indicated the forward scattering of aerosols and there is no significant difference in them over the years.</p> S. Natha Shree R. M.

The present experiment was conducted to assess the character interrelationship and grouping of genotypes based on their performance under water stress. The experiment was conducted in a controlled environment in a complete randomized block design with three replications and two environments (Non-stress &amp; Stress environments). The plant was exposed to drought stress during the first flower bud initiation (i.e., 33 days after sowing). The genotypes were screened on the basis of the results of multivariate analysis viz., pearson correlation, path analysis, modified path analysis, cluster analysis based on usual Euclidean distance and principal component analysis. The Pearson correlation, path analysis and modified path analysis identified the proline content and pod per plant as the critical yield determinants under both the environments. Besides, other significant yield contributing traits for water deficit stress were leaf area, chlorophyll content, pod length and seeds per pod. Usual Euclidean distance-based clustering categorized the genotypes into three groups with substantial variation in cluster composition of both stress and non-stress environment. Based on the relationship of characters and genotypes to the PC 1, it can be concluded that the genotypes AKU 10-6 and SBC 40 can be selected for Number of seeds per pod, Chlorophyll content, number of pods per plant and grain yield per plant characters for breeding purposes in both the environments.</p> Dibosh Bordoloi Akashi Sarma Debojit Sarma ##submission.copyrightStatement## 2022-06-27 2022-06-27 1190 1204 10.9734/ijecc/2022/v12i1030916 Heat Unit and Heat Use Efficiency under Different Growing Environments of Mustard Crop (Brassica juncea L.) <p>A field experiment was conducted at Agro-meteorological Research Farm, A.N.D.

Climate variability has been principal source of fluctuations in Indian food production. Even though there is no long-term trend, inter - annual variability of Indian monsoon rainfall leading to frequent droughts and floods has profound influence on agriculture and intern, national economy. It is well recognized that El Niño / Southern Oscillation (ENSO) is the dominant mode of climate variability on seasonal to inter-annual scales and its impacts are felt worldwide. ENSO often affects seasonal temperature, precipitation and thus crop yields in many regions, however, the overall impacts of ENSO on global yields are uncertain Maximum and minimum average temperature was calculated for different seasons such as Cold Weather Period (CWP), Hot Weather Period (HWP), South West Monsoon (SWM), North East Monsoon (NEM) for each El Niño, La Niña and neutral years at various districts of Tamil Nadu. Relation between ENSO and temperature was analyzed by computing the anomaly in temperature at different districts of Tamil Nadu. The temperature deviation between the ENSO and neutral phases was not significant as the deviation was within <u>+</u> 0.3<sup>o</sup>C in all the seasons.</p> M. Rajavel M. Vengateswari V.

Agricultural crops generate considerable amounts of leftover residues, with increase in food production crop residues also increasing. These leftover residues exhibit not only resource loss but also a missed opportunity to improve a farmer’s income. Crop residue burning has become a major environmental problem causing health issues as well as contributing to global warming. Composting, biochar production and mechanization are a few effective sustainable techniques that can help to curtail the issue while retaining the nutrients present in the crop residue in the soil. The main aim of this paper is to assess the amount of crop residue generated in four major crops paddy, maize, red gram and cotton of Telangana in the year 2021. The assessment of crop residue generation is done using the residue production ratio of the above four crops and the total production in the year 2021 in Telangana state. The results shows that the paddy crop generating high amount of crop residue i.e., 15,29,60,297 followed by cotton, maize and redgram. The generated crop residue is needed to be disposed or managed without causing any harm to the environment. The study suggests that the proper management of crop residue by various methods like in-situ incorporation, cattle feed, industrial purpose etc., instead of burning of the crop residue which causing environmental pollution with the emission of harmful gases.</p> I.

In India, 55 percent of gross sown area accounts 40 percent of food production. In Tamil Nadu, nearly 48 per cent of gross sown area is under rainfed cultivation which is highly vulnerable to climate change and therefore it requires appropriate climate adaptation strategies. The present study covering 180 sample households to examine the farmers perception on climate change and various adaptation responses practiced in rainfed agriculture in Tamil Nadu, Southern India. The farmers were requested to choose one or more response among the three options namely, change in rainfall pattern, change in temperature and decrease in ground water availability. The results of the analysis indicated that rainfall and ground water availability are major concerns due to climate change were perceive by 84 and 58 percent of farmers. The adaptation responses to climate change are examined and the farmers were requested to indicate the various adaptation strategies viz., changing the cropping pattern, drilling new bore wells, deepening existing wells, introducing water saving irrigation methods and reducing the number of irrigations etc. The change in rainfall and temperature perceived by farmers were followed the reduction in number of irrigations, change in cropping pattern, advancement or delaying of cropping seasons and growing rain-fed crops are the major adaptation strategies to reduce the impact of climate change.</p> S.

Among the factors, parent materials/ mineralogy has been considered important for the soil classification besides the Organisms (O) and Relief (R). Inclusion of the parent material covariate for the Digital soil mapping involves implication through geological maps, spectral derivatives and predictive modelling. In this study, the most prominent parent materials identified were derived using the spectral indices formulated based on the Sentinel – 2A multispectral information. While considering the coarse spatial resolution constraints of the existing Landsat -8 bands that may limit certain applications, Sentinel-2 images were used for the indices derivation. The generated mineral maps can support the digital soil mapping of the soil attributes at different spatial scales.</p> M. Nivas Raj R. Kumaraperumal S. Pazhanivelan D. Muthumanickam K. P.

The results revealed highly significant mean squares due to genotypes for all traits studied, indicating the existence of sufficient variation among the genotypes and therefore an ample scope for effective selection. High PCV, GCV, heritability and genetic advance as per cent of mean was observed for 1000-grain weight, seed yield per plant, and harvest index, indicating the effectiveness of direct selection for improvement of these traits. Thousand grain weight and harvest index had recorded positive and significant association with seed yield per plant. The results on path analysis also revealed high and positive direct effect for harvest index followed by flag leaf width, days to 50% flowering, days to maturity, plant height, panicle length, number of filled grains/panicle, number of spikelets/panicle and hence, these traits were identified as the most effective selection criteria for improvement of seed yield per plant in rice genotypes. The results on divergence analysis revealed that the genotypes were grouped into five clusters. Cluster I constituted maximum number of (17) genotypes. Maximum differences among the genotypes within the same cluster (intra-cluster) were shown by cluster I (18.33) followed by cluster II, III, IV, V showed zero intra -cluster distance. Cluster III and V (37.41) showed maximum inter cluster distance, suggesting that the genotypes constituted in these clusters may be used as parents for future hybridization programme. Principal Component Analysis (PCA) was utilized to estimate the relative contribution of various traits for total variability. Five components were found to possess eigen value more than 1.00. The PC1, PC2, PC3, PC4 and PC5 contributed 31.2, 14.5, 12.6, 10.5 and 10.1 per cent of variability. Together, they accounted for 78.9% of the variability of the genotypes used in the study has revealed the traits contributing for the variation.</p> Mudavath Ramesh Naik C. P.

Despite being among the world’s most vulnerable regions, urban mining communities have diverse resources and contribute significantly to the quality of urban climate. The location of urban communities near mining activities has not only attracted urban development in most cities but has also provided these communities with a good opportunity for sustainable ways of living. However, most research on mines seem to have focused on impacts of mining on the environment with little focus on communities’ climate change adaptation responses. This review paper attempts to address this inadequacy in research by exploring factors that increase urban communities’ resilience and the adaptation strategies they use. The study used an evidence-review strategy involving the collection of information from peer-reviewed articles, books, and reports. A total of 213 documents, which included 122 articles, 60 reports, 31 books and gray literature, were identified with the help of Google Scholar and Web of Science search engines. First, the review paper observes that although the concepts of resilience and adaptive capacity are extensively explored, their meanings still remain unclear due to their multiple interpretations. Second, there seems to be very little consensus on factors that lead to increased resilience and the parameters that should be used to measure progress in becoming more resilient due to multiple interpretations of the resilience concept. Third, very few studies seem to have been conducted to assess progress in becoming more resilient in most urban mining communities. Fourth, there also seems to be a challenge in designing vulnerability and resilience assessment frameworks that are procedurally robust, context-specific and appropriate for decision-making related to adaptation action. This study recommends a need to conduct more comprehensive studies which clearly explore factors that increase resilience and adaptive capacity and those that suggest clear policy options for urban mining communities to supplement the rather limited body of literature in this area.</p> Phanuel Chuka Hakwendenda ##submission.copyrightStatement## 2022-04-28 2022-04-28 38 73 10.9734/ijecc/2022/v12i1030771 Anthropocene Bearing on Snow-Avalanche Disasters over the West Indian Himalayas: An Appraisal <p>The Himalayas is massive mountainous hills of altitude about 2000m to 6500m garlanding India in the north extending about 2500km arc-shaped snowy glaciers covering parts of Afghanistan, Pakistan, India, Nepal, China, and Bhutan at various heights in sub-tropics.

Gene transfer by agrobacterium and transformation via a genetically engineered plant virus are two typical approaches for producing efficient vaccinations. Antibodies are an important component of vertebrates' adaptive immune systems, and they may now be made by converting plants with antibody-coding genes from animals and humans. Despite the fact that plants do not produce antibodies naturally, plant-derived antibodies (plantibodies) have been proven to behave similarly to mammalian antibodies. However, as science and technology have progressed, new approaches have been created to improve the efficiency of older technologies including biolistic, electroporation, agroinfiltration, sonication, and polyethylene glycol treatment. Despite the fact that plant-based vaccinations have numerous advantages for the vaccine industry, there are still constraints that limit the rate at which these third-generation vaccines may be successfully manufactured. Despite these limitations, continued attempts are still underway to develop effective vaccines for a variety of human and animal diseases, owing to its enormous potential.</p> Arthee R. S. R.

The direct-type (evaporative) cooling system is widely using natural cooling technology for storage of agricultural produce particularly fruits and vegetables because of its simplicity, eco-friendly and low-cost. But EC system is environment based and got the limitation that cooling of air can be done up to wet bulb temperature. To overcome this and owing to the continuous progress in cooling technology innovations are done by combining other indirect methods with direct type evaporative cooling system. Such system is known as two stage evaporative cooling, includes indirect and direct type cooling system. The indirect cooling has potential to be an alternative to conventional mechanical vapour compression refrigeration system to take up the air conditioning duty. Indirect cooling system is mostly heat exchanger(s) whereas direct cooling is wet pad type system. Combination of these two systems has obtained significantly enhanced cooling performance, with near to 90% and high energy efficiency ratio up to 80. The experimental and research work done on the indirect and direct cooling technology on the basis of their design, structural, type of indirect cooler, materials of construction,&nbsp; pad materials, effectiveness and energy saving have been reviewed and presented. This review paper explains the working principles of two-stage evaporative cooling systems and its performance assessed. This system is energy efficient, environment friendly and having potential for cooling and storage of fruits and vegetables in countries where hot and dry weather prevails for most of the part.</p> K.

The value addition for marketing flowers includes adoption of postharvest technology and improved logistics. Value- addition ensures high premium to the grower, while providing more acceptable quality products for the domestic and export market, and it provides the most important aspects of marketing and give the customers a reason to buy such products. Value addition reduces post-harvest losses and diversifies the economic base of rural communities. The value-added products can be classified into three categories namely fresh flower products, dried flower products and processed flower products. The success of floral industry lies upon by strengthening the fresh flower market through value addition. Dry flower value added products of flowers through different methods have shown promising results. Tinting of cut carnation with food dye Pink and Orange Red @ 5% recorded the fastest uptake of 1 hour <em>Jasminum sambac </em>flowers harvested at the fully open stage yielded better quality essential oil compared with flowers harvested at the closed bud stage. Marigold is one of the richest source of carotenoids especially lutein which possess antioxidant activities and moreover intake of lutein helps in curing age related macular diseases. Natural dyes are mostly used in the colouring of textiles, drugs, cosmetics, etc. Chrysanthemum petals can be used as a substitute of synthetic reactive dyes for dyeing of cotton and silk fabrics (Das <em>et al</em>., 2016). Marigold flower provides a source of carotenoids commercially used in food colouring industries and poultry feed high in carotenoids has been shown to increase performance and egg yolk color as well as decrease egg cholesterol levels.</p> Ali Haidar Shah Arvinder Singh Nomita Laishram Komaljeet Gill ##submission.copyrightStatement## 2022-05-23 2022-05-23 593 613 10.9734/ijecc/2022/v12i1030838 The Role of Organic Farming for Sustainable Agriculture: An Approach to Economic Integrity <p>India is primarily known for its agriculture. Agriculture provides livilyhood for over three-quarters of the people directly and indirectly. As a result, any advancement in agriculture is inextricably linked to the happiness and delight of the people of this country. Agriculture in the India continues to face major issues as the population grows. The growth of high-yielding crop increases the use of fertilizers and irrigation, and as a result of intense cropping techniques, weeds, insects, and pests emerge, wreaking havoc on the crop and its produce. Our economy is founded on property farming, particularly rainfed agriculture, in which vegetables play an important role in feeding humans, animals, and the environment. Country’s most important post-independence worry has been feeding its fast expanding population in an increasing rate. As a result, high-yielding varieties are utilized in conjunction with irrigation water, fertilizers, and pesticides. This combination of high-yielding production has aided the country's development of a food surplus but in the same manner that destroys soil health, enhances environmental pollution, pesticide toxicity. As a result, agricultural systems that rely significantly on organic inputs rather than chemical fertilizers and pesticides are being rethought by researchers and experts. Organic agriculture would generate high-quality feed while also conserving the soil and, as a result, the environment's health; however, whether large-scale organic farming will be able to feed India's huge population remains to be seen. India produces certified organic solutions as well as all types of food products, such as basmati rice, pulses, honey, tea, spices, coffee, oilseeds, fruits, cereals, flavoring medications, and their by-products. Non-edible fresh produce includes cotton, clothing, cosmetics, practical food products, body care goods, and products. But the scope of increasing the organic farming is huge because in India most of the fertile land is cultivated with inorganic inputs.</p> Rachel Taki Animesh Ghosh Bag Shaik Sadhik B.

Moench) is the world's fifth most important cereal and a staple crop for nations in Sub-Saharan Africa and Asia, with great biomass production potential. In the dry and semi-arid tropics, it may be considered as a source of human food, grain, and pasture for cattle, as well as fuel. Abiotic stress factors such as drought, warmth, salt, and submergence remain key limitations to crop growth and yield as a result of climate change. Although sorghum can resist a variety of conditions such as heat, drought, salt, and floods, in dry and semi-arid areas, this crop is typically damaged by water stress at the post-flowering stage. Drought tolerance is a result of morphological and anatomical characteristics (thick leaf wax, leaf rolling, deep root system, and kranz anatomy), as well as physiological responses such as osmotic adjustment via osmoprotectants, stay green traits, quiescence, and ROS-scavenging enzymes such as catalases (CAT), superoxide dismutase (SOD), peroxidases (POD), and ascorbate peroxida (APX). Drought resistance is enhanced by functional proteins such as aquaporin, late embryogenesis abundant (LEA) proteins, heat shock protein, and regulatory proteins such as protein kinase, various transcription factors such as DREB2, bZIP, and phytohormones such as ABA and ethylene. Drought-tolerant sorghum genotypes contain greater osmolyte, chlorophyll, RWC decrease, leaf rolling, and up-regulation of various enzymes and regulatory proteins. When breeding for drought resistance, it's crucial to understand the various drought tolerance mechanisms in plants. The key to generating abiotic stress-tolerant agricultural plants in the future is to understand the physiological underpinning of crop production, crop responses, and crop adaptability in stress-prone locations under sustainable agriculture.</p> Partha Pratim Behera Niharika Saharia Nayanmoni Borah Soibam Helena Devi Ramendra Nath Sarma ##submission.copyrightStatement## 2022-06-16 2022-06-16 1005 1022 10.9734/ijecc/2022/v12i1030891 Relevance of Algae as Biological Indicators of Pollution Management Studies <p>Algae are multicellular or unicellular organisms that photosynthesize but lack the typical features such as leaves, roots, flowers and stems evident in higher vascular plants. They constitute the grasses of the waters. Algae differ in colour and class and occur in all water bodies including lotic and lentic fresh, brackish or salt.

Among the benefits of utilising algae as bioindicators are short life cycles and rapid reproduction, direct influences by physical and chemical environmental factors, a cost effective monitoring tool, and ease of sampling, less labour and less impact on other organisms. Besides, their role in removing different pollutants including heavy metals and other toxic substances from aquatic environments qualify them as candidates for bionindicators.</p> Agbogidi, O. M.
