These private companies could be key actors in financing climate actions in their operating countries<strong>. </strong>Yet, the contribution of private telecommunication companies in financing climate actions in West African countries is not well documented. Accordingly, this study aims to examine the contributions of private telecommunication companies in financing climate actions in the Niger Republic. This study is based on secondary data collected through a systematic review. The literature search was conducted through Web of Science, Google Scholar, and the blog pages of the websites of the key private telecommunication companies operating in the Niger Republic. The findings of the study showed that several climate actions were executed by the key private telecommunication companies operating in the Niger Republic. These included both climate adaptation and mitigation strategies that targeted to combat desertification, fight against youth unemployment, alleviate poverty, reduce population illiteracy, and reduce the exposure of the vulnerable groups to food insecurity. Consequently, an implementation of a comprehensive public-private strategy between the government and the private telecommunication actors to finance climate actions could significantly reinforce the effort of the country to achieve the United Nations Sustainable Development Goals<strong>.</strong>&nbsp;</p> 2021-12-20T00:00:00+00:00 ##submission.copyrightStatement## https://www.journalijecc.com/index.php/IJECC/article/view/30580 Phenotypic Screening of F4 Breeding Lines against Bacterial Blight Disease in Rice 2022-01-10T04:54:52+00:00 K. Alekya kalekya3939@gmail.com B. Laxmi Prasanna M. Balram N. Balram P. Gonya Nayak B. Srinivas P. Madhukar <p>Biotic stresses are major threat to rice production. Among biotic stresses, bacterial leaf blight is one of the major diseases affecting rice grain production in rice growing areas. Present investigation was conducted to evaluate phenotypic effect of 50 breeding lines from a cross (Pranahitha//ISM/MTU1010) in glass house at Regional Agricultural Research Station, Jagtial by inoculating Bacterial leaf blight culture (DX-020) by leaf clipping method. Out of these 50 F<sub>4</sub> lines evaluated, twenty nine breeding lines showed resistant reaction with disease score of 1. Eleven lines showed moderately resistant reaction with disease score 3. Twenty nine breeding lines that were resistant with disease score 1, had excellent grain yield. Hence, these lines can be advanced to further generations. Thus the present study has demonstrated that phenotypic selection is successful in the glass house and these breeding lines with higher yield levels are expected to perform better in the field trials and further in the farmers fields with the good level of bacterial blight resistance.</p> 2021-12-18T00:00:00+00:00 ##submission.copyrightStatement## https://www.journalijecc.com/index.php/IJECC/article/view/30585 Effect of Micronutrients on Growth of Onion (Allium cepa L.) 2022-01-15T05:07:12+00:00 Siddharth Kumar siddhk1996@gmail.com Manoj Kumar Singh Mukesh Kumar Khursheed Alam <p>Onion is one of the most important bulb crop grown all over the India.

During the most recent couple of years, the noble Coronavirus held the world by a threat that caused huge financial mishaps and loss of lives. Simultaneously, the extreme weather events kept on adding to the outrageous climate crisis. To mitigate the effect of climate change, the entire world met up and made various commitments made in various UN conventions, culminating in the Paris Convention to both implement mitigation and adaptation measures to reduce the emissions. The Sustainable Development Goals plan was recognized by all individuals from the United Nations in 2012 at Rio De Janeiro with an expect to propel a sound and created future for the planet and its people. It was in 2015 the Sustainable Development Goals (SDGs) were embraced with 17 goals; with SDGs Goal No.13 addressing earnest activities to combat climate change and its impact in all topographical elements including arid areas. The paper is an attempt to give an overview of the Arid region, climate vulnerability, and to identify the main challenges which climate change presents to the region's future development.

The experiment was laid out in a factorial CRD. The study was undertaken with four ginger varieties namely Gorubathan, Suprabha, Suruchi and Suravi to evaluate the effect of different drying methods (sun drying, hot air drying at 50<sup>O</sup>C, 60oC and 70oC and microwave drying on time required for drying to a moisture content of 8 – 10% and to chemical composition (essential oil, oleoresin content and crude fiber content) of the end product. Results shown that Gorubathan variety has the highest essential oil (2.243%) and oleoresin content (14.840%) among the four varieties in this study, highest crude fiber content (5.253%) was observed in Suprabha and highest dry recovery (25.77%) was obtained from Suravi variety. In hot air drying, with increase in temperature essential oil, oleoresin and crude fiber content in dry ginger as well as dry recovery reduced.</p> <p>With high dry recovery (25.77%), essential oil (2.037%) and oleoresin content (13.510%) and moderately low crude fiber content (4.637%), it can be concluded that Suravi variety is best suitable for producing dry ginger. Apart from microwave drying, sun drying can be recommended as better practice, when hygienically conducted, based on essential oil and oleoresin content.</p> 2021-12-13T00:00:00+00:00 ##submission.copyrightStatement## https://www.journalijecc.com/index.php/IJECC/article/view/30554 Influence of Krishi Vigyan Kendras and Socio-Economic Characteristics towards Adoption of Climate-Resilient Technologies 2021-12-18T13:31:30+00:00 Peddi Naga Harsha Vardhan harsha4447.peddi@gmail.com Prabhat Kumar Pal Deepa Roy <p>Indian economy is mostly dependent on agriculture but climate change is the most threatening phenomena and addressing it as the biggest challenge now a days. ‘In order to reduce the climate change adversities, Indian Council of Agricultural Research (ICAR) with the help of different Krishi vigyan Kendra (KVKs) operated a project called “National Innovations on Climate Resilient Agriculture”. To know the impact of the project a study was conducted in KVKs (i.e., NICRA, KVKs) of two districts of North Bengal i.e., Cooch Behar and Malda. One adopted village and one non adopted village adjacent to adopted village (as control area) were selected for study from each KVK-area.&nbsp; From each village 30 respondents were selected randomly i.e., 60 respondents from adopted village and 60 respondents from non-adopted village. A total of 120 respondents were taken for the research work. The result from this study shows that in the level of awareness, adoption of water-saving technology, in-situ moisture conservation technology, water harvesting, recycling technology and other climate-resilient technologies the mean awareness and adoption score is more in the adopted village than in the non adopted village. The education of household head, total land holding, outside contact score, total yearly income of the family, extent of participation, exposure to interpersonal media, household power access status, level of awareness on climate resilient technology and extent of association with KVK are positively and significantly associated with adoption score. It is also found that in non-adopted villages the socio-economic variables are influencing more towards adoption of climate-resilient technology, whereas, in adopted villages it is due to the association with KVK.</p> 2021-12-13T00:00:00+00:00 ##submission.copyrightStatement## https://www.journalijecc.com/index.php/IJECC/article/view/30555 Assesment of Correlation and Path Analyses for Yield and its Componant Traits in Soybean [(Glycine max (L.)

Positive association of flowering traits (days to tubercles formation→ days to flower budding→ days to first flowering→ days to cessation) and uncorrelated with days to physiological maturity can be precisely utilized in selection. Late physiological maturity increases seedling dry weight, plant height, clusters and seeds per pod while reduces leaf area index, seed weight and dry matter efficiency. With an increase in primary branches corresponding more secondary branches, cluster/plant, seed weight and effective rainfall use efficiency noticed. Effective rainfall use efficiency positively correlated with primary branches, secondary branches, clusters/plant, germination relative index, seedling length, harvest index.

Hanning’s low pass, Mann-Kendall classic test, modified Mann-Kendall test, Mann-Kendall seasonal test and Standard Normal Homogeneity Test were applied to identify the existing trend direction and significance of change over time.</p> <p><strong>Results:</strong> The periods 1980-1996 and 1997-2016 could be considered as wet and dry periods respectively (with a rainfall deficit of 18% after the break in 1996). In addition, we observe a decrease in rainy days of strong accumulation that lead to a significant drop in total annual rainfall. Finally, an abnormal increase in rainfall during the dry season months and a decrease in rainfall during the rainy season months. This indicates an intra-seasonal irregularity (shortening of the rainy season and prolongation of the dry season) of precipitation.</p> <p><strong>Conclusion:</strong> The Hanning filter, M-K test and SNHT are non-parametric tests widely used in the study of climate trends.

S. Anil Kumar Prabha Susan Philip <p>The climate change and land degradation are both individually and in combination have profound influence on natural resource based livelihood systems and societal groups, but this land degradation is caused by land use changes and unsustainable management. The different land use systems practiced in southern agro-climatic zones of Karnataka have significant impact on soil carbon and fertility status of soils, a study was carried out to characterize and classify the soils of southern agro-climatic zones of Karnataka. Five pedons, one from each agro-climatic zone from cultivated land use were selected for the study. Soils of Hiriyur pedons were moderately shallow and rest were deep to very deep, red, well drained and appreciable amount of gravels were observed in all the pedons. Clay illuviation in sub-soil layers was observed hence sub-soil layer contained more clay than surface. The soil texture varied from sandy clay loam to sandy clay and clay. Bulk density of soil varied from 0.86 to 1.86 Mgm<sup>-3 </sup>in the surface. In all the profiles, bulk density increased with depth. Soil reaction varied from very strongly acidic to moderately acidic in Balehonnur and Brahmavara, moderately acidic to neutral in Hassan and Tiptur, neutral to moderately alkaline in Hiriyur. Cation exchange capacity was low and exchange complex was dominated by hydrogen and aluminum. Dominant cations were calcium and magnesium hence base saturation was high in the pedons due to leaching of bases and deposition in sub-surface horizons within the solum except in Brahmvara and Balehonnur was observed.</p> 2021-12-15T00:00:00+00:00 ##submission.copyrightStatement## https://www.journalijecc.com/index.php/IJECC/article/view/30563 Genetic Variability Studies for Yield and Yield Contributing Traits in Rabi sorghum (Sorghum bicolor L.

Deshmukh <p>Genetic variability studies were useful for effective selection in a crop species. Presence of desirable variation and the amount of that variation which is heritable is the primary requirement of any breeding program for the crop improvement. Therefore any breeding program for crop improvement depends majorly on the knowledge pertaining to genetic variability, heritability and genetic advance. The genetic variability study was carried out for yield and yield contributing traits in thirty-seven genotypes of <em>rabi</em> sorghum with three checks namely M 35-1, Phule Suchitra and CSV-22-R at Sorghum Research Station, V.N.M.K.V., Parbhani during <em>rabi</em> 2019. A randomized block design was used with three replications and these treatments were evaluated and data pertaining to eleven traits were recorded with the objective to estimate the genetic variability for the quantitative traits. This investigation revealed presence of highly significant differences among the genotypes indicating presence of large amount of variability in all the eleven characters studied. The study indicated presence of higher estimates of phenotypic coefficient of variation (PCV) for all the traits when compared to genotypic coefficient of variation (GCV) and these estimates are of lower magnitude. Among the forty genotypes studied VJV 107, VJV 106, PEC 30, RSV 1921, RSV 1945 and RSV 1984 were considered as the superior genotypes as these recorded better performance. Higher estimates of GCV and PCV were recorded for the traits; days to 50 per cent flowering, plant height, panicle length, panicle width, fodder yield per plant, biological yield per plant, harvest index and grain yield per plant indicating selection for higher values of these traits of sorghum would be effective. Whereas high heritability coupled with moderate to high genetic advance was observed for traits like plant height, fodder yield per plant and total biomass per plant.</p> 2021-12-15T00:00:00+00:00 ##submission.copyrightStatement## https://www.journalijecc.com/index.php/IJECC/article/view/30564 Evaluation on the Effect of Silica (DE) for Growth and Quality of Mango Kesar 2022-01-04T06:01:38+00:00 A.

Sudharshana sudi.gc@gmail.com Mallikarjun Dhotre Vijay Kumar Didal <p>Scientific evaluation of the land is essential in order to understand the suitability for agricultural and non-agricultural purposes and identification of capabilities and constraints of the land for various crops and their cultivation helps in appropriate and sustainable usage. In order to uplift the production, productivity as well as profitability from a farm land, the knowledge regarding various land resources and soil properties become pre-requisites. In this, direction, a land inventorization was carried out using RS and GIS techniques. The prime objective was to carry out land evaluation studies based on land based on land capability classification and suitability of lands for commonly cultivated crops in the region. Soil morphological features, physical, physico-chemical and fertility properties of the land were analysed and the results indicated that the soils are good in inherent properties even with the slight variation in the morphological and physicochemical properties. Land evaluation based on Land Capability Classification (LCC) revealed that, all the blocks fall under Class-IV with some of the limitations like, erosion, texture and low organic carbon content in soils. Suitability of land to the crops indicated that there are limitations with respect to erosion, slope and soil fertility. Based on the obtained results, corrective measures were suggested for all the blocks to reduce the erosion losses improve the soil properties for higher productivity of the cultivated crops. The study concludes that variation in soils in all blocks is due to the close relationship between soils, physiography and climate which are interrelated.</p> 2021-12-20T00:00:00+00:00 ##submission.copyrightStatement## https://www.journalijecc.com/index.php/IJECC/article/view/30586 Exploring the Relationship between Yield and Yield Attributing Traits in Advanced Breeding Lines of Rice (Oryza sativa L.) 2022-01-17T06:48:47+00:00 Danish Mushtaq Bupesh Kumar Praveen Singh Manmohan Sharma Ashish Sheera sheeraashisssh@gmail.com <p><strong>Aim: </strong>Present study endeavors to explore the genetic variability for various agro-morphological and quality traits as well as to delineate the association between grain yield and its yield attributing components</p> <p><strong>Study Design:</strong> Randomized Complete Block Design</p> <p><strong>Place and Duration of Study:</strong> Division of Plant Breeding and Genetics, She-e-Kashmir University of Agricultural Sciences and Technology of Jammu during <em>kharif </em>2020.</p> <p><strong>Methodology: </strong>A experiment was carried out to determine the association between grain yield and yield attributing components among advanced breeding lines of rice to establish a well grounded selection criteria for developing rice varieties with improved grain yield.

The consequences of underestimation are economic losses, property damages, and loss of life. Therefore, it is important that water resources engineering infrastructure be accurately design to avoid these consequences. This paper evaluates the performances of four probability distributions; GEV, EV1, LP3 and P3 using the annual maxima precipitation series of 26 years for Warri Metropolis obtained from Nigerian Meteorological Agency (NiMet). The strength and weakness of the four probability distributions were examined with the goodness of fit (GOF) module of Easyfit software which implemented Kolmogorov - Smirnov (KS) and Anderson - Darling (AD) tests at 5% significance level. The Easyfit software fitted the precipitation series data to the four probability distributions and ranked the four probability distributions across the fifteen rainfall durations. Results show that for both KS and AD tests, GEV distribution was found to be best-fit distribution and it was applied to the development of IDF curves in Warri Metropolis, Nigeria. Furthermore, the IDF values obtained were applied in the development of three-parameter IDF models for return periods of 10 - , 15 -, 20 -, 25 - , 50 -, and 100-years. The mean absolute error, Nash – Sutcliffe Efficiency (NSE) and Root Mean Square Error (RMSE) indices computed for the IDF models increase with increasing return periods. The IDF curves and models depicted the general attributes of IDF curves and models. This study could be of significant academic value and improvement to professional practice in the design of storm water drainage systems. Therefore, the developed IDF curves and models are recommended to the Warri Urban Authority for inclusion in her stormwater handbooks and manuals.</p> 2021-12-20T00:00:00+00:00 ##submission.copyrightStatement## https://www.journalijecc.com/index.php/IJECC/article/view/30590 Bulk Density of Soils from Oil Palm Agroforestry Systems in Kogi East, Nigeria 2022-01-18T04:31:15+00:00 S.

The climate trend in Sivagangai district was studied using the descriptive statistics of skewness, kurtosis, coefficient of variation and compound growth rate of climatic variables of maximum temperature, minimum temperature and rainfall over the past 50 years from 1971 to 2020. Pearson correlation technique was used to analyze the degree of association between climatic variables and area, production and productivity of principal crops namely paddy, black gram and groundnut. Cobb-Douglas production function model was fitted to study the quantitative relationship between the average production of principal crops grown in the district and the climatic variables of temperature and rainfall and cropped area. Maximum temperature and minimum temperature were negatively skewed and rainfall was positively skewed. Kurtosis for maximum temperature was platykurtic and for the minimum temperature and rainfall of Sivagangai district, the kurtosis was Leptokurtic. The maximum temperature and minimum temperature were less variable and rainfall was highly variable. Pearson correlation coefficient revealed that maximum temperature, minimum temperature and rainfall had significant association with area, production and productivity of crops in Sivagangai district of Tamil Nadu. Cobb- Douglas production function analysis revealed that annual rainfall had a positive relationship with production of paddy.

L. Chaudhary Umesh Singh <p>An attempt has been made to study the impact of Monthly rainfall variability and trend on crop production and productivity of different crops at Kawardha districts of Chhattisgarh state by using long term rainfall (1963-2015). Mean monthly rainfall was more in the month of August (283 mm) where as it was least in December (4 mm) in Kawardha district. The coefficient of variation was highest in the month of December (245 %) and lowest in August (33 %). The CV during July and August is less than 40 % where as it is more than 50 % but less than 60 % in June and September months. The CV is more than 100 percent in rest of the months. The CV in June month is more than 50 percent but less than 60 percent indicates that the crop operations like sowing of crops is uncertain in the month of June. July and August months have lower CV in indicating that the rainfall is stable in the months of July and August but again the CV increased in the month of September and it is around 48 percent in Kawardha districts. Low CV indicates that the rainfall variability is less during monsoon months where as other months show relatively a high value of CV i.e. more than 100 percent. About approximate 80 per cent of the total average annual rainfall concentrated in the south west monsoon and received during a short span of two to three months between June to September. Despite advance technology, still monsoonal rains influence the food grain production to a considerable extent. Kharif food grain production is adversely affected due to monsoon break or failure. This rainfall variability studies can help to plan conservation of excess water and its utilization during their peak requirement. For the purpose of crop planning the rainy days are taken into account and it also plays an important role strategic crop planning.</p> 2021-12-22T00:00:00+00:00 ##submission.copyrightStatement## https://www.journalijecc.com/index.php/IJECC/article/view/30598 Mushrooms Contribution to Farm Income and the Socio-economic Conditions Analysis of the Growers 2022-01-20T11:09:19+00:00 Nitin Sharma nitingautam2720@gmail.com Manoj Kumar Vaidya Bharti Dixit Yachna Sood <p>It is very important to adopt new technology for agricultural productivity and development. Farmers' socioeconomic status influenced their decision to adopt the technology. It is therefore important to study the social status of the farmer. The analysis was based on data based on a survey of 60 farm households. sample was drawn by using a simple random technique from the list of mushroom growers. A complete list of mushroom growers was prepared with the help of the Department of Horticulture, Govt. of Himachal Pradesh and from the supplier of spawn. the analysis of data all the mushroom growers were classified into three categories based on the number of bags, viz., Small Category (≤ 600), Medium Category (601-1200) and Large Category (&gt;1200).&nbsp; Results of the study revealed all of the farmers and most of their families were literate. The literacy status of studied households revealed that 88.25 per cent of family members were literates at an overall level and the literacy index was found 2.69. Among all the three categories all the farmers were small farmers based on landholding. So mushroom farming was preferred by only small farmers. and most of the farmers had an orchard. It is concluded that the main source of income for the farmer is mushroom production. Mushroom contributed maximum in total farm income in case of medium and large category i.e., 43.44 per cent and 72.18 per cent respectively. Overall, its contribution was found 49.42 per cent to the total farm income. Mushroom producer earns more than 52 thousand every month from mushrooms with less than 1200 bags, which is much higher than the average of an Indian.</p> 2021-12-22T00:00:00+00:00 ##submission.copyrightStatement## https://www.journalijecc.com/index.php/IJECC/article/view/30557 A Review on Current Trends in Heavy Metal Removal from Water between 2000-2021 2021-12-27T04:26:22+00:00 Akomah, Uchechi Nwaogazie, Ify.

Present study focuses to review on adaptation practices of affected people with riverine floods in Bangladesh to reduce vulnerability of awaited flood. Consequently, they adopt several adaptation techniques by their life long experience. The major adaptation practiced of the people are raise homesteads using ‘dig-elevate-dwell’ principle of settlement, cultivate flood tolerant paddy (e.g. bona aman), cultivate vegetables in floating bed, tube well have been placed on an elevated base or raised with an additional pipe, and cementing the base of tube well. People also use their indigenous knowledge to cure diseases during flood. Hence, holy basil, and basak (<em>Adhatoda Vasica</em>) are used to treat colds and fevers. On the contrary, durba grass, gando badal (<em>Gaultheria Fragrantissima</em>), garden mint, and Indian pennywort are used for diarrhea and dysentery. Basically, people’s indigenous adaptation techniques have helped them to reduce damages of property and lives as well. Therefore, various types of adaptation should incorporate at the local level plan and implement by the concerned authority.</p> 2021-12-17T00:00:00+00:00 ##submission.copyrightStatement## https://www.journalijecc.com/index.php/IJECC/article/view/30582 Gravity Fed Micro Irrigation System for Small Landholders and Its Impact on Livelihood - A Review 2022-01-11T04:31:52+00:00 T. S. Sherpa tsheringsangmosherpa@gmail.com G. T. Patle K. V. R. Rao <p>Worldwide pressurized micro irrigation technologies have remarkably shown its effectiveness in water saving and increasing the crop yield with several other benefits. Although among the small land holder farmers, adoption of pressurized micro irrigation system is minimal mainly due to the small land holding and more system cost. Gravity micro irrigation is one of the best alternatives for the small land holder farmers with almost all benefits derived by the pressurized micro irrigation. Gravity fed drip irrigation has enormous capability for water and nutrient conservation. This review paper explains design, layout, features of gravity fed micro irrigation system, its suitability and benefits to the small farmers for achieving more yield per drop of water. The comprehensive attempt in the current review analysis is to enhance a most favourable methodology and technology to magnify and intensify the operation of gravity fed drip irrigation system in extensive cultivation and production. Further to accomplish the efficient utilization of available water resources for growing horticultural crops in hilly region of India, gravity-fed micro irrigation should be integrated with water harvesting system.</p> 2021-12-19T00:00:00+00:00 ##submission.copyrightStatement##
