    Advance technology for biostimulants in agriculture
    (Elsevier, 2022) Bahuguna, Ayush; Sharma, Sachin; Rai, Ashish; Bhardwaj, Reshu; Sahoo, Sanjib Kumar; Pandey, Astha; Yadav, Bharti
    Biostimulants are substances, different from fertilizers, which stimulate plant growth when applied in minute quantities. They are increasingly used in worldwide agricultural production and can effectively contribute to overcoming challenges imposed by the increasing world population. These environmentally friendly and natural substances promote vegetative growth, mineral nutrient uptake, and tolerance of plants to abiotic stresses. In the modern agriculture system, biostimulants are obtained from the different communities of naturally occurring microorganisms and the biochemical products produced by them such as organic acid, proteins, enzymes, and hormones. These substances when interacting with the plant-soil continuum enhance the availability or uptake of essential nutrients that are applied in the form of fertilizers or that are already existing in soil or crop residues. The other advanced technology used by different manufacturers is nanosurfactant additives, protein hydrolysates, humic acid, and seaweed with their different modes of action. So, in the current perspective, the use of these advanced technologies in organic farming will help to increase crop productivity, and soil fertility, protect against pathogens, and in turn, increase the income of the farmer. � 2022 Elsevier Inc.

    Evaluating combined effect of different coated urea with PGPR on yield and nitrogen use efficiency in lowland rice by regression model and principal component analysis approach
    (Taylor and Francis Ltd., 2023) Sharma, Sachin; Bahuguna, Ayush; Parihar, Manoj; Yadav, Janardan; Singh, Surendra
    Nitrogen (N) loss is a key problem in rice fields, which results in low nitrogen use efficiency (NUE) of applied N and could be a major limitation from economic and environmental perspectives. In order to improve the NUE, use of slow or controlled released N fertilizers could be a potential alternative to the conventional N inputs. With this objective to evaluate the effect of different slow-release fertilizers on NUE and grain yield of rice, a pot experiment was conducted during kharif 2017 at Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University Varanasi. The experiment comprised thirteen treatments including control, Polymer (PCU) and Neem coated urea (NCU) and their combination with Farm yard manure (FYM) and Plant growth promoting rhizobacteria (PGPR). The combined application of PCU, NCU, FYM and PGPR in treatment T12 provided highest grain yield 47.98 gpot?1and followed by T8 46.60 gpot?1. The result showed that, compared with the PCU treatment T2 (PCU100 Split), the Agronomic efficiency (AE) and Apparent nitrogen recovery efficiency (ANR%) of the mixed doses of coated urea treatment T12 (PCU50 NCU50 FYM10 PGPR Basal) increased by 20.38% and 28.48% respectively. Therefore, application of FYM and PGPR with coated urea improved rice yield, nutrient uptake and their use efficiency and potentially recommended in eastern plain of the Indo-Gangetic Plain for the sustainable production of rice crop. � 2022 Taylor & Francis Group, LLC.

    Nanotechnology: An Efficient Tool in Plant Nutrition Management
    (Nova Science Publishers, Inc., 2022) Sharma, Sachin; Singh, Surendra; Bahuguna, Ayush; Yadav, Bharti; Barthwal, Akshita; Khatana, Raghu Nandan Singh; Pandey, Astha; Thakur, Rajneesh; Jatav, Hanuman Singh
    The increasing global population accelerates world food demand with limited land resources. It shifts the research towards higher productivity with higher fertilizer use on large scale but with high economic inputs. This promotes the use of Nanotechnology in fertilizer industries which offers higher production with the desired customization in nutrient values, high reactivity, changeable surface area, high nutrient use efficiency because of its different physic-chemical properties. Nanoparticles facilitate a smart delivery system of nutrients with the targeted cellular approach in plants as well as in the rhizosphere. The nanopolymers and nano fertilizers also benefit the plant in stress resistance, crop nutrient quality and improve water use efficiency. However, the behavior of nanoparticles to surpass the food chain, its concentration and toxicity in edible products is still a topic of research. The present chapter deals with their mechanisms, controlled release pattern, particle morphology, chemical kinetics, interaction with soil colloids as well as the effect on the microbiome with lesser amount application in the field and proves to replace the current conventional fertilizers with sustainability and minimal environmental risks. � 2022 by Nova Science Publishers, Inc.

    Potential inhibitors and plant based technology: An alternative approach to treat corona virus
    (Academic Press Inc., 2021) Sharma, Sachin; Suvalka, Chetana; Bharti; Joshi, Manoj; Bahuguna, Ayush
    The current pneumonia outbreak, which began in early December 2019 near Wuhan City, Hubei Province, China, is caused by a novel corona virus (CoV) known as �2019-nCoV� or �2019 novel corona virus or COVID-19? by the World Health Organization (WHO). Vaccines are available to prevent corona virus contagious infection or to reduce the viral load in body but virus is continuously mutating itself to infect people at severity. In this critical scenario this review provide a compiled study for techniques and tools that can be used to treat corona virus infections and its variants by some modern techniques and natural products such as inhibitors, siRNA technique and plant based approaches. This review focuses on healthy treatment and strategies that can be used effectively to treat the disease globally by reducing the post COVID symptoms. � 2021 Elsevier Inc.

    Soil Pollution Due to Sewage Sludge and Industrial Effluents
    (Springer Science and Business Media Deutschland GmbH, 2022) Bahuguna, Ayush; Singh, S.K.; Sharma, Sachin; Arvind; Pandey, Astha; Dadarwal, Basant Kumar; Yadav, Bharti; Barthwal, Akshita; Khatana, Raghu Nandan Singh
    In recent times the issue of soil pollution is becoming important as all the nutrient are taken up by plant from the soil. The wastewater treatment produces sewage sludge as an end product, but its primary source is from domestic effluents as well as industrial effluents. Water makes up more than 90% of the sewage water produced in India, 40�50% organics, 30�40% inert compounds, 10�15% bio-resistant organics, and 5�8% miscellaneous components make up the solid fraction. Rapid urbanisation, industrialisation and increasing population generate a huge amount of waste and the waste from industry and the sewage released into the soil as a source of irrigation without being treated properly causes accumulation of toxic heavy metals, persistent organic pollutant, microplastics and high salt that leads to the reduction in the quality of the soil. Similarly, the effluents released by the industries such as distillery, tanning, textile also contains different sources of heavy metals, sodium and other salts and organic chemicals. This chapter providesa detailed aspect of soil pollution from the industry as well as sewage sludge. � 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

    The Risk Associated with Crop Ecosystem Management and Pesticides Pollution
    (Nova Science Publishers, Inc., 2022) Chitara, Manoj Kumar; Singh, Rajesh Pratap; Gupta, Prince Kumar; Mishra, Dhruv; Jatav, Surendra Singh; Sharma, Sachin; Jatav, Hanuman Singh
    Pesticides are large groups of chemical compounds including herbicides, insecticides, fungicides, nematicides, rodenticides, and plant growth regulators etc., commonly used for crop protection against pests. Indiscriminate utilization of pesticides could adversely impose the risk to food safety, the environment and the living population. Farmers are ignoring the risk associated with pesticides used, safety guidelines, and protective directives in crop management. The improper utilization of pesticides caused the degradation of the quality and fertility of the soil as well as disturbing the nutrient cycling, which leads to heavy metal deposition and toxicity. Excessive exposure of the pesticide to the insect population will be created the development of insect pest resistance, resurgence and decline of the population of the natural enemies. Disposal of unwanted pesticides waste is responsible for the pollution of the water reservoir, groundwater, and pond water sources. The bio-magnification of contaminant cause health associated risk in human beings and animal at different levels of the food chain. In this chapter, we are discussing in detail the risk associated with pesticide application and crop management. � 2022 by Nova Science Publishers, Inc.

    Rhizosphere microbiomes are very complex ecosystems on the earth and play an important role in plant growth promotion, nutrient recycling, and soil fertility. The diversity of rhizosphere microbiomes in cereal crops is primarily regulated by soil type, root exudates, host genotype, and land use patterns. It is essential to understand the dynamic responses of rhizosphere microbiomes to physical, chemical, and biological changes for developing sustainable agricultural practices in disturbed soil ecosystems. This chapter is aimed to address the structure and function of rhizosphere microbiomes of cereal crops with a special emphasis on biotechnological applications for its yield improvement. Mechanisms of plant growth-promoting rhizobacteria in cereal crops production have been selectively highlighted in this chapter with suitable examples. � 2022 Elsevier Inc. All rights reserved.
