Advances in Organic Farming: Agronomic Soil Management Practices
(Elsevier, 2021) Vijay Singh Meena; Sunita Kumari Meena; Amitava Rakshit; Johnson Stanley; Cherukumalli Srinivasarao
Advances in Organic Farming: Agronomic Soil Management Practices focuses on the integrated interactions between soil-plant-microbe-environment elements in a functioning ecosystem. It explains sustainable nutrient management under organic farming and agriculture, with chapters focusing on the role of nutrient management in sustaining global ecosystems, the remediation of polluted soils, conservation practices, degradation of pollutants, biofertilizers and biopesticides, critical biogeochemical cycles, potential responses for current and impending environmental change, and other critical factors. Organic farming is both challenging and exciting, as its practice of “feeding the soil, not the plant” provides opportunity to better understand why some growing methods are preferred over others. In the simplest terms, organic growing is based on maintaining a living soil with a diverse population of micro and macro soil organisms. Organic matter (OM) is maintained in the soil through the addition of compost, animal manure, green manures and the avoidance of excess mechanization. © 2021 Elsevier Inc.

Agriculturally important microbes for sustainable agriculture
(Springer Singapore, 2017) Vijay Singh Meena; Pankaj Kumar Mishra; Jaideep Kumar Bisht; Arunava Pattanayak
This book presents a compilation of case studies from different countries on achieving agricultural sustainability. The book stresses that, in order to meet the needs of our rapidly growing population, it is imperative to increase agricultural productivity. If global food production is to keep pace with an increasing population, while formulating new food production strategies for developing countries, the great challenge for modern societies is to boost agricultural productivity. Today, the application of chemicals to enhance plant growth or induced resistance in plants is limited due to the negative effects of chemical treatment and the difficulty of determining the optimal concentrations to benefit the plant. In the search for alternative means to solve these problems, biological applications have been extensively studied. Naturally occurring plant-microbe-environment interactions are utilized in many ways to enhance plant productivity. As such, a greater understanding of how plants and microbes coexist and benefit one another can yield new strategies to improve plant productivity in the most sustainable way. Developing sustainable agricultural practices requires understanding both the basic and applied aspects of agriculturally important microorganisms, with a focus on transforming agricultural systems from being nutrient-deficient to nutrient-rich. This work is divided into two volumes, the aim being to provide a comprehensive description and to highlight a holistic approach, respectively. Taken together, the two volumes address the fundamentals, applications, research trends and new prospects of agricultural sustainability. Volume one consists of two sections, with the first addressing the role of microbes in sustainability, and the second exploring beneficial soil microbe interaction in several economically important crops. Section I elucidates various mechanisms and beneficial natural processes that enhance soil fertility and create rhizospheric conditions favourable for high fertility and sustainable soil flora. It examines the mechanism of action and importance of rhizobacteria and mycorrhizal associations in soil. In turn, section II presents selected case studies involving economically important crops. This section explains how agriculturally beneficial microbes have been utilized in sustainable cultivation with high productivity. Sustainable food production without degrading the soil and environmental quality is a major priority throughout the world, making this book a timely addition. It offers a comprehensive collection of information that will benefit students and researchers working in the field of rhizospheric mechanisms, agricultural microbiology, biotechnology, agronomy and sustainable agriculture, as well as policymakers in the area of food security and sustainable agriculture. © Springer Nature Singapore Pte Ltd. 2017.

Arbuscular mycorrhiza: a viable strategy for soil nutrient loss reduction
(Springer Verlag, 2019) Manoj Parihar; Vijay Singh Meena; Pankaj Kumar Mishra; Amitava Rakshit; Mahipal Choudhary; Ram Prakash Yadav; Kiran Rana; Jaideep Kumar Bisht
Arbuscular mycorrhiza fungi’s (AMF) role in plant nutrition and stress management is well known, but very few researches and studies have been conducted so far on the fungal ability to reduce different nutrient losses (runoff, leaching and volatilization) from the soil system. This important ecosystem service of AMF had been neglected largely. From the recent findings, it has been confirmed that mycorrhizal symbiosis has potential to check the losses of applied nutrients. The role of soil biota in nutrient cycling is indispensable and determines the nutrient availability to plants. Among these biota, AMF’s association with plants is the most prevalent, but the exact mechanisms followed by AMF in nutrient cycling, transformation and reducing nutrient loss ability are still inconclusive. In this review, we will try to unlock this particular aspect of AMF which is important to achieve global food demand in a sustainable way. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

Beneficial microbes associated with plant roots play an important role to achieve higher agriculture production for burgeoning population in sustainable way. Among various microbes, arbuscular mycorrhizal (AM) fungi interaction with higher land plants is unique as they occupy position both inside and outside of roots. AM fungi as a natural symbionts of land plants provide various ecological services, in particular by improving plant water and nutrition availability, soil health and fertility, alleviating stress condition and wasteland management. Mycorrhizae as a broader group of fungi include seven types of members, i.e. arbuscular, ecto, ectendo, arbutoid, monotropoid, ericoid and orchidaceous, while arbuscular and ectomycorrhizae are the most abundant and ubiquitous. In this chapter, we focus on AM fungi and provide an overview on mycorrhizal interaction, benefits, processes, production development and potential application domain under various conditions. Along with recent advances in AM fungi role under various stress condition, reclamation of problematic wastelands and production aspects, we also discuss about the basic features of AM fungi with past developments to provide an overall glimpse of this plant-fungal interaction. In spite of its growing trends, AM fungi’s current application and market sharing are far below to full potential. Regarding this, current challenges, constraints and strategies for future road map to overcome these problems are also discussed briefly. © Springer Nature Singapore Pte Ltd. 2020.

Can bacillus species enhance nutrient availability in agricultural soils?
(Springer International Publishing, 2017) Vijay Singh Meena; B.R. Maurya; Sunita Kumari Meena; Rajesh Kumar Meena; Ashok Kumar; J.P. Verma; N.P. Singh
One major challenge for the twenty-first century will be the production of sufficient food for the global human population. The negative impacts on soil-plant- microbes-environmental sustainability due to injudicious use of chemical fertilizer, pesticide, insecticide, etc. by the unaware farmers deteriorate soil and environment quality. One possible way to use efficient soil microorganisms to remediate nutrient deficiency in agricultural soils and other plant growth-promoting (PGP) activities that can be of help for plant growth and development. The Bacillus species is one the most dominant rhizospheric bacterial/rhizobacteria species like Bacillus subtilis, B. cereus, B. thuringiensis, B. pumilus, B. megaterium, etc. that can help enhance the plant growth and development by different mechanisms, which PGPR can inhibit phytopathogens is the production of hydrogen cyanide (HCN) and/or fungal cell wall degrading enzymes, e.g., chitinase and β-1,3-glucanase. Direct plant growth promotion includes symbiotic and non-symbiotic PGPR which function through production of plant hormones such as auxins, cytokinins, gibberellins, ethylene, and abscisic acid. Mitigate the challenge by adopting eco-friendly crop production practices. Some Bacillus species function as a sink for 1-aminocyclopropane- 1-carboxylate (ACC), the immediate precursor of ethylene in higher plants, by hydrolyzing it into a-ketobutyrate and ammonia and in this way promote root growth by lowering indigenous ethylene levels in the micro-rhizo environment. Bacillus species also help in solubilization of mineral phosphates, potassium, zinc, and other nutrients; rhizobacteria retain more soil organic N and other nutrients in the soil-plant system, thus reducing the need for fertilizers and enhancing release of the nutrients from indigenous or mineral sources, enhancing the economic and environmental sustainability. © Springer International Publishing AG 2016.
Can potassium-solubilising bacteria mitigate the potassium problems in India?
(Springer India, 2016) Madhumonti Saha; Bihari Ram Maurya; Indra Bahadur; Ashok Kumar; Vijay Singh Meena
The nutrients are one of the basic inputs for achieving increased crop productivity, and potassium is one of them. In a recently published nutrient budget, it has been shown that potassium became unbalanced through increased removal and increased system leakage, simplification (monoculture) and increased demand for rapid plant growth. Addressing this nutrient imbalance and shortages in developing countries, it would be required to enhance the world production of potassium fertiliser. India is not self-sufficient in producing potassium fertiliser. The entire quantities of potassium fertilisers are imported. Therefore efficient management in soil fertility is a prime concern to the scientist in view of the increasing gap between production and consumption of fertiliser with time. So, nowadays, crop nutrient stability is important to mitigate the exhaustion of soil nutrient stock for sustaining the crop yield and to reinstate the soil fertility. In these circumstances, it is suitable to study the present knowledge of substitutive sources of K. So this assessment imparts an opportunity to flourish native mineral sources of K as a substitute to impede costly remunerative fertilisers. So, bio-intrusion of potassium minerals with potassium-solubilising microorganism (KSM) would be a preferable and feasible technology to solubilise unavailable form of K minerals into available pool for plant uptake and efficiently used as a source of K fertiliser for maintaining the ecological balance and sustaining agricultural production and environmental quality. © Springer India 2016.

Co-inoculation with Enterobacter and Rhizobacteria on Yield and Nutrient Uptake by Wheat (Triticum aestivum L.) in the Alluvial Soil Under Indo-Gangetic Plain of India
(Springer New York LLC, 2017) Ashok Kumar; B.R. Maurya; R. Raghuwanshi; Vijay Singh Meena; M. Tofazzal Islam
The aim of this work was to evaluate the effects of co-inoculation with phosphate-solubilizing and nitrogen-fixing rhizobacteria on growth promotion, yield, and nutrient uptake by wheat. Out of twenty-five bacteria isolated from the rhizosphere soils of cereal, vegetable, and agro-forestry plants in eastern Uttar Pradesh, three superior most plant growth-promoting (PGP) isolates were characterized as Serratia marcescens, Microbacterium arborescens, and Enterobacter sp. based on their biochemical and 16S rDNA gene sequencing data and selected them for evaluating their PGP effects on growth and yield of wheat. Among them, Enterobacter sp. and M. arborescens fixed significantly higher amounts (9.32 ± 0.57 and 8.89 ± 0.58 mg Ng−1 carbon oxidized, respectively) of atmospheric nitrogen and produced higher amounts (27.06 ± 1.70 and 26.82 ± 1.63 TP 100 µg mL−1, respectively) of IAA in vitro compared to S. marcescens (8.32 ± 0.39 mg Ng−1 carbon oxidized and 21.29 ± 0.99 TP 100 µg mL−1). Although both M. arborescens and S. marcescens solubilized remarkable amounts of phosphate from tricalcium phosphate likely through production of organic acids, however, Enterobacter sp. was inactive. The effects of these three rhizobacteria were evaluated on wheat in alluvial soils of the Indo-Gangetic Plain by inoculation of plants with bacterial isolates either alone or in combinations in both pot and field conditions for two successive years. Rhizobacterial inoculation either alone or in consortium of varying combinations significantly (P ≤ 0.05) increased growth and yield of wheat compared to mock inoculated controls. A consortium of two or three rhizobacterial isolates also significantly increased plant height, straw yield, grain yield, and test weight of wheat in both pot and field trials compared to single application of any of these isolates. Among the rhizobacterial treatment, co-inoculation of three rhizobacteria (Enterobacter, M. arborescens and S. marcescens) performed best in promotion of growth, yield, and nutrient (N, P, Cu, Zn, Mn, and Fe) uptake by wheat. Taken together, our results suggest that co-inoculation of Enterobacter with S. marcescens and M. arborescens could be used for preparation of an effective formulation of PGP consortium for eco-friendly and sustainable production of wheat. © 2017, Springer Science+Business Media New York.
Documentation of five potassium- and phosphorus-solubilizing bacteria for their K and P-solubilization ability from various minerals
(Elsevier Ltd, 2017) Debabrata Nath; Bihari Ram Maurya; Vijay Singh Meena
The ability of a few soil bacteria to transform unavailable forms of phosphorus (P) and potassium (K) to an available form is an important feature in plant growth-promoting bacteria for increasing crop yields of high- P and K-demand crops. In this research, screening and characterization of thirty-five K-solubilizing bacterial (KSB) and P-solubilizing bacteria (PSB) isolate which were evaluated for their ability to solubilize K and P from the waste muscovite (WM), waste biotite (WB), tri-calcium phosphate (TCP) and rock phosphate (RP) by analyzing the soluble P and K content after 7, 14, 21 days after incubation (DAI) at 28±2 °C on MABs (Modified Aleksandrov Broths) and Pikovskaya's medium. The soluble P and K contents in all isolates were significantly (p<0.01) higher than the contents in nonbacteria treatment. K-release from WB varied significantly from 3.5 to 5.0 µg mL−1, 4.4–6.3 µg mL−1 and 5.3–7.2 µg mL−1 at 7, 14 and 21 DAI, respectively. Herein, isolate KSB-105 had caused significantly higher K-release as compared to rest of isolates. Overall K-release from WB was highest by PSB-56 with 7.2 µg mL−1. While, significant higher amount of P-release was observed at 21 DAI (13.7 µg mL−1) followed by at 14 DAI (12 µg mL−1) and lowest was recorded at 7 DAI (5.1 µg mL−1). PSB-56 showed it's significantly superiority in P-release from TCP at 21 DAI (13.7 µg mL−1) as compared rest of isolates. Overall, it can be concluded that the diversity of KSB and PSB as bioinoculants to release K and P provides a win-win situation under in vitro condition. Therefore, it is crucial to adopt efficient KSB and PSB isolates in interventions for the judicious use of chemical and biological resources for maximizing food production while reducing pollution and rejuvenating degraded land for sustainable agriculture. © 2017 Elsevier Ltd
Does a rhizospheric microorganism enhance K+ availability in agricultural soils?
(Urban und Fischer Verlag Jena, 2014) Vijay Singh Meena; B.R. Maurya; Jay Prakash Verma
The potassium solubilizing microorganisms (KSMs) are a rhizospheric microorganism which solubilizes the insoluble potassium (K) to soluble forms of K for plant growth and yield. K-solubilization is carried out by a large number of saprophytic bacteria (Bacillus mucilaginosus, Bacillus edaphicus, Bacillus circulans, Acidothiobacillus ferrooxidans, Paenibacillus spp.) and fungal strains (Aspergillus spp. and Aspergillus terreus). Major amounts of K containing minerals (muscovite, orthoclase, biotite, feldspar, illite, mica) are present in the soil as a fixed form which is not directly taken up by the plant. Nowadays most of the farmers use injudicious application of chemical fertilizers for achieving maximum productivity. However, the KSMs are most important microorganisms for solubilizing of fixed form of K in soil system. The KSMs are an indigenous rhizospheric microorganism which shows effective interaction between soil and plant systems. The main mechanism of KSMs is acidolysis, chelation, exchange reactions, complexolysis and production of organic acid. According to literature, currently negligible use of potassium fertilizer as a chemical form has been recorded in agriculture for enhancing crop yield. Most of the farmers use only nitrogen and phosphorus and not use the K fertilizer due to unawareness so that the problem of K deficiency occurs in rhizospheric soils. The K fertilizer is also costly as compared to other chemical fertilizers. Therefore, the efficient KSMs should be applied for solubilization of a fixed form of K to an available form of K in the soils. This available K can be easily taken up by the plant for growth and development. Our aim of this review is to elaborate on the studies of indigenous K-solubilizing microbes to develop efficient microbial consortia for solubilization of K in soil which enhances the plant growth and yield of crops. This review highlights the future need for research on potassium (K) in agriculture. © 2013 Elsevier GmbH.
Does integrated nutrient management, enhance agricultural productivity?
(Journal of Pure and Applied Microbiology, 2015) Lokesh Kumar Jat; Y.V. Singh; Santosh Kumar Meena; Sunita Kumari Meena; Manoj Parihar; H.S. Jatav; Raj Kumar Meena; Vijay Singh Meena
Nowadays the global food demands of a growing human population and need for an eco-friendly strategy for sustainable soil-plant-microbes-environmental system, require significant attention when addressing the issue of enhancing agricultural productivity. One possible way to enhance crop productivity by chemical fertilization, but due to injudicious uses of chemical input in agricultural system detonated the soil, food, environmental and human health, chemical fertilization also increasing their prices 21st century. However, it is not possible to supply all the nutrient requirements of crops through organic manures. So by taking into consideration the above facts, integrated nutrient management (INM) has been developed. Here we discuss the role of INM in resolving these concerns, which has been proposed as a promising strategy for addressing these challenges. INM has multifaceted potential for the improvement of plant performance and resource efficiency while also enabling the protection of the environment and resource quality. Lower inputs of chemical fertilizer and therefore lower human and environmental costs (such as intensity of land use, N use, reactive N losses and GHG emissions) were achieved under advanced INM practices without any negative effect on crop yields. A comprehensive literature research revealed that INM increases crop yields by 8-150% as compared with conventional practices, increases water and nutrients use efficiency and the economic returns to farmers, while improving grain quality and soil health and sustainability. Strong and convincing evidence indicates that INM practice could be an innovative and environment friendly practice for sustainable agriculture worldwide. © 2015 Journal of Pure and Applied Microbiology.

Effect of nitrogen levels and seed bio-priming on root infection, growth and yield attributes of wheat in varied soil type
(Elsevier Ltd, 2017) Sunita Kumari Meena; Amitava Rakshit; Harikesh B. Singh; Vijay Singh Meena
There is increasing interest in the use of beneficial microbes as alternatives to chemical fertilizers and plant growth promoters in agricultural production. Judicious application of Trichoderma sp. with chemical nitrogenous (N) fertilization to seeds will be an efficient mechanism for placement into varied soil type (alluvial, red and black) where they enhance the colonize seedling roots and establishment of the plant. Significantly higher leaf area was recorded with T2 (RDF of NPK @ 120-60-60 kg ha−1) in both growth stage of wheat as compared to rest of the treatments. Data at 30 days after sowing (DAS) revealed that leaf area range significantly varied between ~ 59 to 86, 15 to 26 and 26 to 55 cm2 plant−1 under alluvial, red and black soils, respectively. Results clearly indicated that the root infection was significantly varied at 30 DAS from 5% to 18%, 6% to 23% and 5% to 14% for alluvial, red and black soils, respectively under different treatment combinations. It was significantly higher with T1 (Control NPK @ 0-0-0 kg ha−1) and the values were respectively for ~ 18%, 23% and 14% in alluvial, red and black soils. However, the combined application of N and seed bio-priming resulted in highest root infection incidence in the red (14.87%) followed by alluvial (12.40%) and black (8.73%) soils. Significantly higher grain yield was recorded with T2 (RDF of NPK @ 120-60-60 kg ha−1) followed by T3, T4, T5 and T1 treatments. It was varied significantly between 0.56 to 6.35, 0.20 to 2.65 and 0.36 to 5.12 g pot−1 under alluvial, red and black soils, respectively. The combined application of T. harzianum with chemical N fertilization will be one of the sustainable solutions for improving the ability of seed bio-priming to establish and function consistently in the field for sustainable crop production. © 2017 Elsevier Ltd
Effect of seed bio-priming and N doses under varied soil type on nitrogen use efficiency (NUE) of wheat (Triticum aestivum L.) under greenhouse conditions
(Elsevier Ltd, 2016) Sunita Kumari Meena; Amitava Rakshit; Vijay Singh Meena
This study was aimed to investigate an impact of bio-priming by Trichoderma harzianum BHU51, varied N doses (100%, 75%, 50% and 25% RDN) along with varied soils types (alluvial, red and black) on wheat (Triticum aestivum L.) under greenhouse conditions. Results revealed that significantly enhanced plant height, chlorophyll content, root length, effective tillers growth and yield parameters of wheat with different soil type under greenhouse conditions by the application of various treatments. Significantly higher effective tillers, chlorophyll content and root length were recorded with recommended dose of fertilizers (RDF) of NPK @ 120-60-60 kg ha-1 followed by seed bio-priming with T. harzianum+3/4th N and RDF of PK. The seed bio-priming also enhanced the plant growth and nitrogen use efficiency (NUE). Agronomic use efficiency (AUE) and physiological use efficiency (PUE) were significantly higher with alluvial soil as compared to black and red soils. The principal component analysis revealed that root length and N uptake were the most important property to improve the NUE. The results indicated suitability of Trichoderma harzianum BHU51 as a bio-priming agent in improving NUE and wheat crop productivity. © 2016 Elsevier Ltd.
Evaluation of potassium solubilizing rhizobacteria (KSR): enhancing K-bioavailability and optimizing K-fertilization of maize plants under Indo-Gangetic Plains of India
(Springer Verlag, 2018) Vijay Singh Meena; Abbu Zaid; Bihari Ram Maurya; Sunita Kumari Meena; Indra Bahadur; Madhumonti Saha; Ashok Kumar; Rajhans Verma; Shabir H. Wani
Imbalanced potassium (K) fertilization in agricultural fields has led to considerable negative impacts and remains to be the foremost challenge for maize production in India-Gangetic region. Plant growth-promoting rhizobacteria, particularly potassium solubilizing rhizobacteria (KSR), could serve as inoculants and a promising strategy for enhancement of plant absorption of K hence reducing dependency on chemical fertilizers. Maize seeds were microbiolized for 30 min with KSR suspensions. In the present study, the use of chemical fertilizers along with Agrobacterium tumefaciens strain OPVS10 showed pronounced beneficial effect on growth and yield attributes in maize. There was a significant difference among different parameters studied when varying doses of K and KSR strains were applied. Results showed that the combined application of KSR strain OPVS10 with 100% RDK (recommended dose of K) was most effective in modulating growth, physio-biochemical, and yield attributes in maize thus could be regarded as a promising alternative to mineral K-fertilization. Principal component analysis (PCA) revealed that 100-grain weight and grain yield were the most important properties to improve the sustainable growth of maize. Therefore, these KSR strains have different mechanisms for modulating various activities in maize plants. Results suggested that the synergistic application of KSR strain OPVS10 with 100% RDK can be used for optimized breeding, screening, and nutrient assimilation in maize crop. Hence, this eco-friendly approach may be one of the efficient methods for reducing dependency on chemicals, which pose adverse effects on human health directly and indirectly. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature.
Handbook of Energy Management in Agriculture
(Springer Nature, 2023) Amitava Rakshit; Asim Biswas; Deepranjan Sarkar; Vijay Singh Meena; Rahul Datta
This handbook provides a holistic overview of different aspects of energy management in agriculture with an orientation to address the sustainable development goals. It covers possible applications not only from a technical point of view, but also from economic, financial, social, regulatory, and political viewpoints. Agriculture is one of the most imperative sectors that contribute to the economy across different agro-ecologies of the universe with energy inputs in each stage of production, from making and applying chemicals to fueling tractors that lay seeds and harvest crops to electricity for animal housing facilities. The majority of agricultural research has focused on the use of input, production, and productivity, whereas rational energy budgeting and use remain an overlooked and likely underestimated segment, ignored so far while formulating agro-ecosystem framework. Energy management study is a new frontier of agriculture and is challenging duе to complex enterprises, spatial-temporal variability, exposure to pollution, and the predominant effect of the anthropogenic factor on ecology and environment. But it is worth taking the challenge considering the important prerequisite role of energy for sustainable development which has been evidenced from increasing research in recent times. Of recent origin, there are critical, in-depth studies around the globe assessing the capture and flow of energy in the ecosystem, which will help to develop a conceptual framework to incorporate this vital resource in the agriculture management template. This book is a state-of-the-art resource for a broad group of readers including a diversity of stakeholders and professionals in universities, public energy institutions, farmers and farming industry, public health and other relevant institutions, and the broader public as well. © Springer Nature Singapore Pte Ltd. 2023.
