  • A Review on River Revival

    • Authors: Ayushi Trivedi, Manoj Kumar Awasthi
      Pages: 202 - 210
      Abstract: The noticeable decline of flow and drying of rivers in non-monsoon period is observed by smaller hydrologic units (sub-catchments and watersheds). The flow depletion or drying of rivers is generally observed initially near the origin and then progressively in the larger hydrologic units. Rivers are losing water because of variety of possible reasons, including the installation of dams and the use of water for agriculture. But in many cases the decrease in flow is because of climate change, which is altering rainfall patterns and increasing evaporation because of higher temperatures. Reduced run-off is increasing the pressure on freshwater resources in world as well as in India, especially with more demand for water as population increases. Inspite of the fact that large sums of money have been spent on river rehabilitation across the globe, the understanding of the science of restoration is incoherent. A scientific and global intervention and approach to tackle such challenges to river management in India requires a highly effective approach, which must be process-based, predictive and must be capable of yielding the desired outcome. River restoration is one of the most prominent areas of applied water-resources science, supporting a multibillion dollar industry across many countries and helping to drive fundamental river research to address knowledge gaps that limit successful restoration. A revival strategy should identify a future prospect and long run for the river basin, the desired outcome of the strategy over the planning horizon (goals), and specific, measurable targets to be achieved over the short to medium term (objectives). River restoration can be supported by a combination of policies, strategies and project-level and global-level plans. Keeping this in view this paper presents some of the revival works carried out in India as well as in abroad.

  • Development of Solar Operated Walking Type Power Weeder

    • Authors: A. R. Kachhot, M. S. Dulawat, J. M. Makavana, U. D. Dobariya, A. L. Vadher
      Pages: 211 - 223
      Abstract: Power weeders are most commonly used machines for removing weeds, to prevent them from competing with main crops. However, these power weeders are power by either petrol or diesel engine. With the shortage of fossil fuel, its unavailability in rural areas and for reducing emission due to burning of fossil fuel, an alternative energy powered weeder is very much required. As solar energy was very available and weeding usually carried out during daytime, hence an attempt made to develop a solar energy operated weeder for dryland. It comprised of a powering system and a blade assembly. The power source included solar photovoltaic panel, solar charge controller, battery, motor charge controller and BLDC motor. The sweep type blade was used, which is mounted behind the main frame and power was given to the rear wheels by 750 watt 48 volt BLDC motor using a chain and sprocket drive. The performance of weeder was evaluated at three different forward speed of S1, S2 and S3 is 1.0 - 1.5, 1.5 - 2.0 and 2.0 – 2.5 km/h respectively. Total weight of weeder is 88 kg and total force required to push the weeder at 2.5 km/h was 107 kg (730 watt).  Four batteries, each of size 12 V, 12 amp, powered the motor. Two solar panels were use to charge the battery, each with a power of 150 watts, and it takes 2 h to completely charge the battery while weeder is in steady state. The battery was discharge in 1.3 h in field when solar panel disconnected. With simultaneous charging and discharging of battery, this solar power system could run the weeder for 7.3 h. The developed weeder was teste in groundnut crop having 600 mm row-to-row spacing up to 30 to 40 mm depth with a field capacity of S1, S2 and S3 was 0.042, 0.059 and 0.075 ha/h. The weeding and field efficiency for S1, S2 and S3 were found to be 90.94, 84.69, 83.50% and 79.21, 83.97, 85.68% respectively. The effect of forward speed S1, S2 and S3 on Energy expenditure rate and heart rate was found to be 8.23, 9.27 and 10.34 kJ/min or 94, 98 and 50 bpm respectively. The plant damage increased with increasing forward speed of operation, Hence the developed solar operated walking type power weeder could be used successfully by the a small scale farmer for carrying out weeding operations.

  • Influence of Weather Parameters and Thermal Time Approach on Green Gram at
           Coimbatore, Tamil Nadu

    • Authors: S. A. Naveen, S. Kokilavani, S. P. Ramanathan, G. A. Dheebakaran, S. Anitta Fanish
      Pages: 1 - 5
      Abstract: An investigation was carried out at the Agro Climate Research Centre, Tamil Nadu Agricultural University, on the effect of weather parameters on the green gram yield sown at various sowing dates during the rabi season of 2019. At various sowing dates, two green gram cultivars, VBN 4 and ADT 3, were sown. For both cultivars, the phonological crop length decreased with delays in sowing dates beyond October 23rd. The yield of green gram sown on 23rd October was significantly higher than the crops sown on 30th October and 6th November. The weather parameters Maximum Temperature (Tmax), Diurnal Range (Trange), Bright Sunshine Hours (BSS), Relative Humidity (RH I), Wind Speed (WS) were found to be negatively correlated with seed yield whereas Minimum Temperature (Tmin), Relative Humidity (RH II), Vapour Pressure (VP) were found to be positively correlated with the yield of green gram. The accurate prediction of green gram yield could be done with the maximum temperature, bright sunshine hours, wind speed and with thermal indices especially hygrothermal unit II with 82 percent, accuracy level.

  • Performance of F2 Rice (Oryza sativa L.) Segregants Derived from a Cross
           the BPT-5204 / IR-64Drt1

    • Authors: Anjani Kumar, D. N. Singh, Krishna Prasad, Avinash Pandey
      Pages: 31 - 47
      Abstract: The present investigation was carried out with F2 plants from a cross between two parents i.e., BPT-5204 and IR-64Drt1. The selection of parents for crosses was made based on genotypes that were tolerant and susceptible to drought condition. BPT-5204 was drought susceptible and IR-64Drt1 was also tolerant to drought. In this experiment adequate amount of variability was detected for grain yield per plant and its components among 324 segregants evaluated under augmented randomized block design II in normal field condition. The analysis of variance for grain yield and its attributing characters among blocks, treatments, entries, checks and checks vs entries revealed presence of significant variation in the segregants studied. However, with respect to checks, non-significant differences were recorded for only L/B ratio. The results indicated that among 324 rice genotypes including checks, only 9 rice genotypes expressed higher yield compared to seven checks varieties under normal field condition. The segregants S-51, S-122, S-135, S-195, S-199, S-210, S-219, S-222, S-251 were top ranking genotypes with respect to all checks.

  • Changing Rainfall and Swinging Tea Production: The Correlates and
           Perception of Social Ecology of Tea Garden

    • Authors: Dristika Jairu, S. K. Acharya, Anwesha Mandal
      Pages: 48 - 54
      Abstract: Tea is the second most commonly consumed beverages, after water, across the globe. However, the quality and aroma of the produce largely depends on different climatic factors like temperature, rainfall, altitude etc. Even a slight alteration in these climatic factors, affects the quality and production adversely. Climate change, a global challenge, is a big threat to the tea industry as well as its workers. With degraded quality and swinging production due to changing rainfall and temperature, hundreds of tea gardens have been closed down in the past few decades, putting livelihood of thousands of tea workers to question. This paper attempts to find how the changing rainfall and swinging tea production varies with the profile characteristics of the tea workers. The study was conducted in the Darjeeling, Kalimpong and Dooars districts of West Bengal with 90 randomly selected tea workers from nine randomly selected tea gardens, three each belonging to three different altitudes. All the results has been analyzed using statistical tools of correlation coefficient, multiple and stepwise regression and path analysis. The results shows that treatment and mobility are two important variable explaining the variation in perception on change in rainfall and perception on tea production respectively. It has also been found that variables like income, treatment and garments have been reliable predictors for estimating the change in rainfall whereas the variable mobility exhibits a positive and significant relationship with perceived change in tea production. The regression analysis showed that treatment has explained 19.4 per cent of total variation in case of perceived change in rainfall and mobility has explained 16 per cent of total variance in case of perceived change in tea production.

  • Study of Groundwater-river Interactions Using Hydrochemical Tracers in
           Fissured Rock: Case of the Lobo Watershed at Nibéhibé (Central-West,
           Côte d’Ivoire)

    • Authors: Gningnéri Souleymane Ouattara, Brou Dibi, Arthur Brice Konan- Waidhet, Jules Mangoua Oi Mangoua, Bamory Kamagate
      Pages: 55 - 66
      Abstract: Water is a vital resource for all populations. However, there are warning signs that the water from the Lobo River used by SODECI to supply drinking water to the population is declining in quantity during the dry season and its quality is becoming poor due to climate variability and anthropogenic activities. However, the river is able to maintain a certain flow, probably with the contribution of groundwater. It is therefore a question of whether there is really a connection between surface water and groundwater. The aim of this study is to characterize the groundwater-river interactions based on the physico-chemical parameters of the Lobo watershed in Nibéhibé. The approach adopted is a coupled statistical-geochemical approach applied on data from two sampling campaigns (dry and rainy season). This coupled approach consisted, on the one hand, in understanding the chemical specificities within the water classes using the piper diagram and, on the other hand, in classifying the waters according to their physico-chemical similarity and highlighting the phenomena at the origin of the water mineralization using the Kohonen self-organized map (SOM). The results obtained from the piper diagram show that in both the wet and dry seasons, the chemical signature of the waters remains controlled by two main hydrochemical facies: the chlorinated calcium-magnesium nitrate hydrofacies and the bicarbonate calcium-magnesium hydrofacies. Kohonen's self-organized map has established that the mineralization of groundwater, under natural conditions, comes from the nature of the rocks crossed during infiltration and from the contact time between water and minerals. This work provides managers with decision-support tools for planning and searching for groundwater in support of surface water to reinforce the drinking water supply of the populations in this watershed.

  • Livelihood Dependence on Highland Pastoralism (Doksa) in Trans-Himalayan
           Region of Zanskar, Ladakh

    • Authors: Anup Raj, Dorjey Angchuk, M. A. Islam
      Pages: 67 - 76
      Abstract: A unique system of short-distance vertical transhumance pastoralism has evolved in the Trans-Himalayan region of Zanskar, Ladakh in response to short summer cropping season and vast alpine pasturelands. Cattle are taken to highland pastures for three-and-a-half month in summer season and kept in temporary settlements locally called as doksa. The study investigated the herding practices, migration pattern, livestock production and livelihood dependence on highland pastoralism. Purposive sampling technique was administered to withdraw the sample of 6 doksas and the data were collected from both secondary and primary sources. Results revealed that 31 herders in the 6 doksas possessed a total of 794 milk producing zhomos. The doksas produced 3 lakh litres of milk, 18000 kg of butter and the same amount of dried protein cake (chhurpey). The herders earned incomes of ₹ 122500.00 and ₹ 59375.00 by trading 300-350 kg of butter and 450-500 kg of chhurpey, respectively with employment opportunities of 3100 woman-days/year. The poor living conditions at doksa and unavailability of alternative economic opportunities for women herders has threatened its continuation for cash generation, food and livelihood security and socioeconomic development. Therefore, livelihood diversification using alternative resources is imperative to keep pace with current development and future challenges.

  • Development of a High Quality, Rapid, Efficient and Economical DNA
           Extraction Protocol from Climate Resilient Pearl Millet Crop Without
           Liquid Nitrogen

    • Authors: Supriya Ambawat, Subaran Singh, C. Tara Satyavathi, Rajbala Meena, R. C. Meena, Vikas Khandelwal
      Pages: 85 - 94
      Abstract: Extraction of good quality genomic deoxyribonucleic acid (DNA) from plants is a major prerequisite for molecular biology experiments. An efficient genomic DNA protocol must be simple, fast and cost effective with high yield and purity. Presence of polyphenols, polysaccharides and secondary metabolites in some plants hamper with DNA extraction making it a very laborious, difficult and time consuming procedure. Here, we portrayed a modified protocol based on the cetyl trimethyl ammonium bromide (CTAB) method to isolate DNA from climate resilient pearl millet leaf tissues having higher amount of polysaccharides. It also excludes the use of expensive chemicals and equipments like proteinase K, liquid nitrogen and tissue lyser. This method includes extraction of DNA using a buffer (pH 8.0) containing 200 mM Tris-HCl, 20 mM ethylenediamine tetracetic acid (EDTA),1.4 M NaCl, 2% CTAB, 2% sodium dodecyl sulphate (SDS) and 1.0 % β-mercaptoethanol followed by purification of DNA with phenol, chloroform, isoamyl alcohol and finally precipitation of DNA by sodium acetate and isopropanol. Good quality genomic DNA with sharp and clear bands was obtained from 48 pearl millet genotypes using this protocol. The yield of DNA varied from 105.2 to 328.3 ng/μl. The purity of DNA sample ranged from 1.74 to 1.95 based on the absorbance at A260/A280 ratio indicating that it’s free from ribonucleic acid (RNA) and protein contamination. PCR analysis using simple sequence repeat (SSR) primers exhibited consistent and reliable amplification products ranging from 150 to 650 bp.This study reveals a fast, simple, efficient, specific, reproducible, reliable and cost effective method for extraction of DNA from small to large number of plant samples amenable to PCR amplification and could be stored for longer duration.

  • In vitro Screening of Iron Efficient Groundnut Cultivars for Calcareous

    • Authors: V. S. Reddy Kiran Kalyan, S. Meena, D. Jawahar, S. Karthikeyan
      Pages: 137 - 148
      Abstract: Aims: In the present study twenty groundnut genotypes are evaluated for their resistance to IDC and to identify feasible indicators for screening iron (Fe) efficient groundnut genotypes in calcareous soils based on the morphophysiological parameters at 45 days after sowing (DAS). Study Design: The experiment was replicated three times with two iron treatments (+Fe and – Fe) in a randomized block design Place and Duration of Study: Field screening of genotypes was carried during Kharif 2019 at Thondamuthur block, Coimbatore district (10°59’31.9” N 76°47’15.4 E), Tamil Nadu, India. Methodology: The randomized field experiment was comprised of two major factors, i) Fe status (with Fe, without Fe), and ii) genotypes (twenty) with differential IDC response. Seven morpho-physiological parameters associated with IDC resistance were evaluated in groundnut genotypes. Results: Under Fe deficit conditions, IDC efficient genotypes recorded significantly higher shoot dry weight, root dry weight, root volume, SPAD values, active Fe, catalase activity, peroxidase activity, and higher yield compared to susceptible ones because of better Fe utilization efficiency. The various morpho-physiological parameters studied showed a significant correlation with pod yield. The four genotypes viz., TAG 24, CO 7, VRI 8, and VRI-16086 were efficient under both sufficient and deficit conditions under calcareousness. The stepwise multiple regression shows the peroxidase (POD) accounts for 71 % under +Fe condition and SPAD accounted for 66 percent in -Fe in predicting the pod yield. Hence, POD and SPAD can be used as indicators for selecting Fe efficient groundnut cultivars for calcareous soil. Conclusion: The findings indicate that SPAD values are most optimal for the initial large-scale screening of groundnut genotypes for tolerance to IDC, whereas peroxidase may be used to validate established genotypes.

  • Perceived Climate Resilience and Adoption of Cocoa Agroforestry in the
           Forest-Savannah Transition Zone of Ghana

    • Authors: Ishmael Hashmiu
      Pages: 149 - 161
      Abstract: Aims: Agroforestry is globally acknowledged as an essential component of climate-smart agriculture. Nevertheless, agroforestry adoption is low, and research is lacking on how farmers perceive the climate-related benefits of agroforestry and the implications of such perceptions on adoption. This paper assessed farmer perspectives on the effectiveness of agroforestry in enhancing the climate resilience of cocoa, and the extent to which such perceptions (in conjunction with socioeconomic factors) influence farmers’ decision to adopt cocoa agroforestry or otherwise. Study Design: A cross-sectional survey design involving households practicing different cocoa landuse systems (agroforestry vs. full-sun monoculture) was used. Methodology: Data were collected using structured questionnaire administered to 240 randomly selected cocoa-farming household heads. Place and Duration of Study: The study took place in 12 rural communities in the Forest-Savannah Transition Zone of Ghana from March to September 2017. Results: Findings indicated that while farmers unanimously acknowledged the effectiveness of cocoa agroforestry in enhancing resilience to excessive dry season temperatures, their perceptions in terms of resilience to drought differed, and were largely shaped by the kind of shade trees integrated. Overall, the majority of household heads perceived agroforestry to be the most beneficial strategy for enhancing the climate resilience of farmers. This perception significantly influenced households’ decision to adopt cocoa agroforestry, in conjunction with socioeconomic factors such as social network, sex of the household head, sex distribution of the household, and off-farm income. Conclusion: Social network and farmers’ perception of the effectiveness of agroforestry in enhancing climate resilience are the key determinants of cocoa agroforestry adoption in the FSTZ of Ghana. Farmers who perceive agroforestry to be the most beneficial climate-resilient strategy in agriculture are more likely to adopt cocoa agroforestry. Social network can be used to enhance cocoa agroforestry adoption by serving as an effective communication channel for spreading information about the climate-related benefits of shade trees among farmers.

  • Pre Harvest Forecasting of Kharif Rice Yield Using Weather Parameters for
           Strategic Decision Making in Agriculture

    • Authors: Y. A. Garde, V. S. Thorat, R. R. Pisal, V. T. Shinde
      Pages: 162 - 170
      Abstract: In the recent year, pre harvest crop yield forecasting has been a topic of interest for producers, policy makers, government and agricultural related organizations. Pre harvest crop forecasting is important for national food security. Construction of appropriate yield forecast promotes the output of scenario analyses of crop production at a farm level, which enables suitable tactical and strategic decision making by the farmer. Indeed, considerable benefits apply when seasonal forecasting of crop performance is applied across the whole value chain in crop production. Timely and accurate yield forecast is essential for crop production, marketing, storage and transportation decisions as well as for managing the risk associated with these activities. In present manuscript efforts were made for development of pre harvest forecast models by using different statistical approaches viz. multiple linear regression (MLR), discriminant function analysis and ordinal logistic regression. The study utilized the crop yield data and corresponding weekly weather data of last 30 years (1985-2014). The model development was carried out at 35th and 36th SMW (Standard Meteorological Week) for getting forecast well in advance of actual harvesting of the field crop. The study revealed that method of discriminant function analysis gave best pre harvest forecast as compare to remaining developed models. It was observed high value of Adj. R2= 0.94, low value of RMSE= 164.24 and MAPE= 5.30. The model can be used in different crop for reliable and dependable forecast and these forecasts have significant value in agricultural planning and policy making.

      Abstract: Africa is under pressure from climate stresses and is highly vulnerable to the impacts of climate change. In Kenya, agriculture is the backbone of the economy making it an important contributor to food security of rural households. Currently crop productivity is being affected by continued climate variations and decline in soil fertility. Adaptation to climate change requires to be given high and urgent priority for sustainable crop production. A study was conducted in Mavuria ward, Mbeere South Sub-County, Embu County to evaluate the effects of climate change adaptation on crop production. The study used both descriptive and experimental research designs. The primary data on adaptation measures was collected from farmers and institutions using questionnaires. In the data analysis, descriptive statistics were used to organize the climate data and that of the respondents into frequencies. Further, a Pearson correlation test was done to determine the relationship between farmer and institutional based mechanisms on adaptation to climate change at α=0.05. The main adaptation mechanisms identified were soil fertility improvement, soil and water conservation, early planting, pest and disease control, provision of certified seeds, and awareness creation. In view of these findings, the study recommends continuous implementation of these measures that can help strengthen farmers and institutional adaptation mechanisms towards climate change for improved crop production.

    • Authors: Y. Siva Lakshmi, D. Sravanthi, R. Susheela, A. V. Ramanjaneyulu, P. Raghu Rami Reddy
      Pages: 183 - 192
      Abstract: Tornala village of Siddipet District (Previously part of Medak district) in Telangana State comes under low rainfall area with an average annual rainfall of 787.6 mm and experiences extreme seasonal variation in rainfall. A new Agricultural Research Station was established in 2014 to meet the agricultural needs of adjoining areas of Siddipet District. Maize is one of the principal crops of the Siddipet District grown in light soils under rain fed situation. Erratic behaviour of rainfall results in moisture stress of both kinds (excess and deficit) during maize growing season which is leading to frequent crop failures. Millets and pulses are gaining importance which can be grown very well under rainfed situation. To create awareness among the farmers about the importance of other drought tolerant crops suitable for the situation and also to promote drought resistant and short duration, nutritional rich pulse crops in place of maize was the primary objective in conducting this trial. Keeping the above in view, a field experiment was conducted to identify a suitable crop comparable/ alternative to maize with a view to reduce the risk of crop failure under rain fed conditions and to realize the nutritive value of millets. Nine crops viz. Bajra, Ragi, Korra, Maize, Green gram, Pigeon pea, Cotton, Castor Hybrid (PCH 111) and Castor variety (Kranthi) were evaluated for three years. Yields of all the crops were converted into maize equivalent yields and economics was worked out. Pooled means were worked out for yield as well as for economic returns. Results showed that higher maize equivalent yield was recorded in Pigeon pea (4354 kg ha-1) followed by Bajra (2804 kg ha-1), ragi (2604 kg ha-1), cotton (2344 kg ha-1) and green gram (2075 kg ha-1).  In terms of net returns pigeon pea recorded highest mean net returns (39080 Rs ha-1) followed by bajra (25553 Rs ha-1) and ragi (20614 Rs ha-1) whereas highest mean benefit cost ratio was with bajra (2.44) followed by pigeon pea (2.41) and ragi (2.05) compared to maize (2297 Rs ha-1 and 1.08 respectively). Hence, from the study it can be recommended that Bajra, Pigeon pea and Ragi can be grown in place of maize in low rain fall areas of Siddipet (Dt) under rain fed situation.

    • Authors: Vinay Kumar Gautam, M. K. Awasthi, Ayushi Trivedi
      Pages: 224 - 232
      Abstract: The continuous decrease and irrational use of water resources is the key issue for the proper application of water resources in tribal areas of Jabalpur district. This study attempts to propose a new aspect of optimum allocation of land & water resources in Jabalpur District. The minimum cultivated area that ensures food requirement and land constraint have a direct impact on water resources allocation. To conduct an accurate program for land and water resource allocation for water deficit area a multi- constraint linear programming model (LPM) was developed by implanting land resource as a constraint on water resources allocation which has to be considered by the demand of water resources in the agriculture sector. The result shows that increase in major crops area like rice, wheat, gram, maize and oilseeds crop areas against the reduction in sorghum, lentil, and sugarcane. Existing cropping intensity of the district was 150 %. To achieve the maximum profit per unit of land i.e. cropping intensity more than 200% for district, therefore an extensive measures was made for district to fix out the water demand supply gap for agriculture. In this study a user friendly Linear programming software was used to develop a model for optimum allocation of resources under seasonal and multi-crop condition for Jabalpur district. The net annual profit is increased by 9.1% under optimal allocation conditions. The sensitivity analysis of model parameter shows that the superior price of crop is the most sensitive parameter followed by the crop area. The results obtained from this study will definitely help policy makers to decide how to properly utilize and promote the water and land resources for the available area.

      Pages: 247 - 254
      Abstract: In recent years air pollution is one of the biggest problems in the world. Owing to the transboundary dispersion of contaminants around the world, air pollution has its own peculiarities. In a much planned urban setup industrial pollution takes a backseat and cooler admission takes the president's as the major cause of urban air pollution in the present investigation your pollution torrents index was calculated for various plant species growing around the Allahabad Highway. Five plants available commonly in all locations were selected for the present research namely Azadirachta indica (Neem), Delonix regia (Gulmohar), Saraca asoca (Ashok), Ficus benghalensis (Bargad), Ficus religiosa (Pepal). Using normal procedures, ascorbic acid, leaf extract pH, overall chlorophyll, relative water content and air quality tolerance index were analysed. Both plants tested in both areas have been shown to be pollution-sensitive, varying from 02.29 to 12.53. No pollution tolerant organisms studied were found. The maximum value of pH was 7.8 found in Neem tree spp. (Azadirachta indica) in Rewa Road (NH-35) and the minimum value of pH was 5.9 found in Gulmohar tree spp. (Delonix regia) in Varanasi Road (NH-19), The maximum value of RWC (89.99 %) found in Ashok tree spp. (Saraca asoca) and the minimum value of RWC (58.64 %) found in Neem tree spp. (Azadirachta indica) in Mirzapur Road site (NH-76). The maximum value of Total Chlorophyll Content was 1.55 mg/g found in Ashok tree spp. (Saraca asoca) in Mirzapur Road (NH-76) and the minimum value of Total Chlorophyll Content was 0.71 mg/g found in Bargad tree spp. (Ficus benghalensis) in Control Site and Rewa Road (NH-35). The maximum value of Ascorbic Acid (1.07 mg/g) found in Ashok tree spp. (Saraca asoca) in Rewa Road site (NH-35) and the minimum value of Ascorbic Acid (0.39 mg/g) found in Pepal tree spp. (Ficus religiosa) in Mirzapur Road site (NH-76) The variance may be due to alternative biochemical parameters being reflected. Plant can filter the air through aerial elements especially through their twigs stem leaves air pollution management is the better manage by the afforestation program. Air pollution tolerance index (APTI) is an intrinsic quality of tree to control air pollution problem which is currently of major concern of local urban locality. The trees having higher tolerance index rate or tolerant towards air pollution and can be used as a major component to reduce air pollution whereas the tree having less tolerance index can be an indicator to know the rate of air pollution. Hence, it is essential to protect the plants.

  • How States Can Drive the Next Era of Climate Management in India:
           Perspectives in Mainstreaming Climate Actions from Gujarat

    • Authors: Shanal Pradhan, Shwetal Shah
      Pages: 255 - 263
      Abstract: At the September 2019 UN climate action summit, India vowed to upscale its climate action by focusing on a low carbon pathway through renewables and other forms of clean energy, adopting sustainable mobility, preserving water, and securing finances for this transition. Implementing and up scaling these actions form an influential agenda under India’s Nationally Determined Contributions (NDCs) to the Paris Agreement. The emphasis on national determination and its success strongly hinges on the ambition of the states and the seriousness it has for driving climate actions. The initial step is to streamline such activities at sub-national levels to achieve climate change goals. Indian states, like countries, are too at different starting points with dissimilarities in their economic and developmental interests. Climate priorities took center stage for a few states, while many others have not been too aspirational due to misplaced prerogatives and differing capabilities. Thus, a pertinent question which arises is, could cross-pollination of ideas and innovations push states for concrete climate actions' This paper discusses a few prominent initiatives from the progressive state of Gujarat that could facilitate the exchange of climate measures in other states.

      Pages: 264 - 270
      Abstract: A field experiment was conducted at the farmer’s field at Ratanpur village of Marshaghai block of Kendrapara, Odisha, India to evaluate effect of different mulching practices on weed population, moisture content in soil and yield of brinjal. The village is an adopted village by Krishi Vigyan Kendra Kendrapara, in which various activities in agriculture are going on under National Innovations on Climate Resilient Agriculture (NICRA) programme to combat the flood-affected area of the locality. The experiment consists of five mulching treatments like Black polythene mulch, Black and silver polythene mulch, Transparent mulch, Organic mulch (rice straw) and No mulch. Results revealed that black with silver colour polythene mulch was recorded with significantly higher yield per plant (2.59 kg) and yield per ha (62.1 t/ha) which was at par with black colour polythene mulch. Organic mulch was found to be next best treatment with respect to yield per plant (2.40 kg) and yield per ha (53.5 t/ha). The same treatment also resulted in the higher gross return (Rs. 434700/ha), net return (Rs. 274150/ha) and B:C ratio (2.71) which was followed by black polythene mulching and organic mulching practices. Weed suppression and moisture retention was higher with black polythene mulch.

  • Breeding for Early Flowering in Chickpea (Cicer arietinum L.) – A Key
           Strategy to Accelerate Chickpea Productivity: A Review

    • Authors: Aswini Nunavath, K. Gopala Krishna Murthy, Venkatraman Hegde, S. Madhusudan Reddy
      Pages: 271 - 285
      Abstract: Chickpea is one of the most important pulse crop cultivated across the globe which is conventionally a low-input crop that is being cultivated mostly in moisture deficient rainfed environments during post-rainy season. The crop is being severely affected with various biotic and abiotic stresses among which, drought and heat stress are considered as serious constraints limiting chickpea productivity in sub-tropical regions. Several strategies were adopted to enhance the productivity under drought and heat stress environments among which, the development of early flowering varieties is one of the key strategies gaining importance in recent past. Some of the early / super early varieties like ICCV 2, JG 11, JG 14, KAK 2, JAKI 9218, ICCV 96029 and ICCV 96030 were developed during the last three decades. One of the most significant milestones in breeding for early varieties is the identification of four genes efl-1, efl-2, efl-3 and efl-4 governing early flowering by using various lines viz., ICCV 2, ICCV 96029, ICC 5810, BGD 132 and ICC 16641. Several QTLs controlling time of flowering were also mapped on linkage groups LG1, LG2, LG3, LG4, LG5, LG6 and LG8. The information on inheritance of time of flowering, correlation between early flowering with other yield attributing traits like number of pods per plant, number of seeds per pod, seed size, 100-seed weight, identified QTLs for early flowering and abiotic and biotic stresses tolerance may be useful for developing early maturing varieties that posses tolerance to various abiotic stresses by using different conventional and biotechnological approaches.

      Pages: 286 - 299
      Abstract: Climate change carries immense threat to the livelihood and food security of smallholder farmers in Bhutan and it is therefore crucial to enhance their adaptive capacity.  However, building resiliency to climate impact require information on vulnerability of the system of interest. Therefore, this study assessed smallholder farmers’ vulnerability to impacts of climate change and variability in central regions (Bumthang and Trongsa) of Bhutan. Data was collected from 247 randomly selected households by administering a pre-tested survey questionnaire. Data was analyzed using composite index approach (LVI) and IPCC framework approach (LVI-IPCC). The LVI analysis revealed that Bumthang was more vulnerable in terms of Socio-demographic profile (0.55), social networks (0.45), health (0.31) and natural disasters and climate variability (0.47) compared to Trongsa. Whereas, Trongsa was more vulnerable in terms of livelihood strategies (0.31) and water (0.13). Vulnerability score on the food component was same for both the districts (0.27). Overall, Bumthang was more vulnerable compared to Trongsa on both LVI (Bumthang: 0.36, Trongsa: 0.34) and LVI-IPCC (Bumthang: 0.24, Trongsa: 0.13) analysis. The findings could be used for designing micro-level context specific interventions to enhance smallholder farmers’ adaptive capacity to impacts of climate change in central Bhutan.

      Abstract: Fossilfuel requirement is the necessity for fulfilling the global energy needs, which is increasing day by day due to this it will drain in future. Bio-energy became as one of the vital alternatives to replace fossil fuel. Thermochemical conversion of biomass for obtaining the bioenergy is getting more popular in the recent time. In the present study, slow pyrolysis is used for bio-energy production from the waste biomass available in the form of crop residues of Groundnut Shell (GS), Chana Straw (CS) and Wheat Straw (WS) using the developed continuous biochar production system (Pratap Kiln) to produce biochar. An energy recovery system consisting of cooling chamber was developed to recover the bio-oil from the waste flue gas (syngas). The pyrolysis of selected biomass was carried out at 450°C and residence time of about 4 min. The yield of biochar and bio-oil and syngas properties were determined. The maximum biochar yield was found in CS feedstock as 35% followed by WS and GS, i.e. 33% and 29%, respectively. The bio-oil recovery in GS, CS and WS was 31%, 26% and 30% respectively, whereas the syngas production was 40%, 39% and 37% respectively.

      Abstract: A field experiment was conducted during rabi season of 2018-19 and 2019-20 in Dryland experimental field belong to soil order Inceptisols, Biswanath college of Agriculture, Assam Agricultural University, Biswanath chariali, Assam to study the ‘‘Yield and yield attributing parameters of toria (Brassica campestries) under real time rainfall situation in an Inceptisols of Assam, India’’ under AICRPDA, NICRA. The treatments consisting of 4 different dates of sowing i.e. S1-41th SMW, S2-44th SMW, S3-46th SMW, and S4- 48th SMW, & three variety i.e. V1-JT-90-1(Jeuti), V2-Yellow sarson (Benoy) and V3- TS-38. Growth, yield and yield attributing characters of toria varieties were influenced by different dates of sowing. S1 registered higher plant height (43.2 cm, 92.9 cm and 106.6 cm & 40.2 cm, 89.8 cm and 101.5 cm) and number of branch (3.8, 5.3 and 7.2 & 3.4, 5.1 and 6.9) at 30 DAS, 45 DAS and 60 DAS, respectively, during 2018-19 and 2019-20. Yield attributing characters like number of siliqua, number of seed per siliqua, 1000 seed weight (g) were gradually decreased with advancement of sowing dates. Among the three varieties V1 (Jeuti) recorded highest seed yield (8.9 q ha-1 and 8.1 q ha-1) and stover yield (23.4 q ha-1 and 22.2 q ha-1) in 2018-19 and 2019-20, respectively. Highest HI (28.5% and 25.8%) was recorded in S1 and lowest was recorded in S4 (20.7% and 14.6%).

  • As Climate Change Responds with Terrifying Brutalities

    • Authors: Nura Jibo MRICS
      Pages: 322 - 330
      Abstract: Introduction: The lip service in tackling the climate change issues five years after the famous Paris Agreement on climate change is quite unwholesome to individual countries' pledges and promises that were made on reducing global carbon emissions at Le Bourget, France. The attempt to limit the global mean temperature to 1.50 Celsius preindustrial level has even resulted in warming the climate more than anticipated [1]. The bulk of the climate change adaptation and mitigation effort(s) have, generally, ended up in a tragic fiasco. The rise in sea level and temperature overshoot carry substantial and enormous risks and uncertainties that have caused the entire humanity to head towards an irreversible crossing tipping point [2].  For example, the year 2020 horrible flooding; animal and plant species extinction; coral reef death; permafrost melt; loss of sea and land ice; breaking of the two major glaciers in the coast of the Amundsen Sea in West Antarctica that has kept climatologists and meteorologists terrified in studying the Pine Island and Thwaites glaciers, are all cases in point that proved an irreversible condition of the climate change.  Methodology: This paper used content analyses by reviewing the climate change brutal scenarios that occurred at random globally. The data on climate events was obtained from the existing literature on the magnitude of destruction of flood rains and storms’ damage due to sea level rise that is exacerbated by the breaking away of the two major glaciers in the coast of the Amundsen Sea in West Antarctica. Results: The paper examined critically the flood scenarios that occurred in Puerto Rico; Arecibo; Panzhihua; Gopalganj; Kara-Kache; Krasnoyarsk; Tlalpane; Talas; Taif; Valencia; Lagamenas; Khabarovsk; Hadejia; Dabi; Magarya; and Auyo etc. It revealed that massive flooding was witnessed globally within a span of a weeklong catastrophe. Sea level had risen by at least 0.05 percentile as a result of the breaking away and melting of the two glaciers at the coast of the West Antarctica. Conclusion: The paper concluded that human beings are no longer near the target of achieving the 1.50–20C goal. What remains now is for everyone to understand the dangers of the climate change blind investment that has already thrown the entire world habitat into a déjàvu phenomenon.
