    (Federation of Eurasian Soil Science Societies, 2022) Mohapatra, Kiran Kumar; Singh, Satish Kumar; Patra, Abhik; Jatav, Surendra Singh; Rajput, Vishnu D.; Popova, Victoria; Puzikova, Olesya; Nazarenko, Olga; Sushkova, Svetlana
    Soil Zn amended is an efficient agronomical Zn biofortification approach in rice. However, it is still need to know if higher rate of Zn over recommended dose can influence other essential nutrient uptake, high accumulation of Zn in soils and health risk for human consumption. This study was conducted by taking ten treatments (T1: control, T2: RDF, T3: RDF + 1.25 mg kg-1, T4: RDF + 2.5 mg kg-1, T5: RDF + 3.75 mg kg-1, T6: RDF + 5 mg kg-1, T7: RDF + 6.25 mg kg-1, T8: RDF + 7.5 mg kg-1, T9: RDF + 8.75 mg kg-1, T10: RDF + 10 mg kg-1) on hybrid rice in Zn (1.20 mg kg-1) enriched soil. The findings have shown that 6.25 mg kg-1 Zn application significantly increased crop growth and grain concentrations of N, K, Zn, Cu and Fe by 71.4, 125, 78.9, 28.5 and 2.4%, respectively. Nutrient harvest index was significantly affected by ranged between 29.1�36.4%. Application of Zn at 6.25 mg kg-1 (T7) recorded the highest Zn concentration in grain (28.2 mg kg-1) and bioavailability of the fortified Zn (2.05 mg Zn day-1). The lowest phytatic acid concentration in grain was recorded in T8 (RDF + Zn at 7.5 mg kg-1) and after that a significant increase was observed. Transfer coefficient was inversely behaving with Zn application and ranged between 6.03�18.0 grain. The average daily intake of Zn was ranged between 0.075�0.118 mg-1 kg-1 day. Across different treatments the Zn build-up factor, geo-accumulation index and soil enrichment factor was ranged between 0.98�4.90,-0.61�1.70 and 0.24�1.82, respectively in post-harvest soil. In conclusion, agronomic biofortification of Zn through soil applications at 6.25 mg Zn kg-1 was a sustainable way to improving growth and grain Zn, N, K, Cu and Fe uptake of hybrid rice to meet human recruitment. � 2022 Federation of Eurasian Soil Science Societies.

    Coping with the challenges of abiotic stress in plants: New dimensions in the field application of nanoparticles
    (MDPI AG, 2021) Rajput, Vishnu D.; Minkina, Tatiana; Kumari, Arpna; Harish; Singh, Vipin Kumar; Verma, Krishan K.; Mandzhieva, Saglara; Sushkova, Svetlana; Srivastava, Sudhakar; Keswani, Chetan
    Abiotic stress in plants is a crucial issue worldwide, especially heavy-metal contami-nants, salinity, and drought. These stresses may raise a lot of issues such as the generation of reactive oxygen species, membrane damage, loss of photosynthetic efficiency, etc. that could alter crop growth and developments by affecting biochemical, physiological, and molecular processes, causing a significant loss in productivity. To overcome the impact of these abiotic stressors, many strategies could be considered to support plant growth including the use of nanoparticles (NPs). However, the majority of studies have focused on understanding the toxicity of NPs on aquatic flora and fauna, and relatively less attention has been paid to the topic of the beneficial role of NPs in plants stress response, growth, and development. More scientific attention is required to understand the behavior of NPs on crops under these stress conditions. Therefore, the present work aims to comprehensively review the beneficial roles of NPs in plants under different abiotic stresses, especially heavy metals, salinity, and drought. This review provides deep insights about mechanisms of abiotic stress alleviation in plants under NP application. � 2021 by the authors. Licensee MDPI, Basel, Switzerland.

    Feasibility of sewage sludge application in rice-wheat cropping system
    (Federation of Eurasian Soil Science Societies, 2021) Jatav, Hanuman Singh; Singh, Satish Kumar; Jatav, Surendra Singh; Rajput, Vishnu D.; Sushkova, Svetlana
    A field experiment was conducted to find out the effect of the conjoint application of sewage sludge (SS) and fertilizers on the yield of rice-wheat cropping system using a randomized block design. The grain yield ranged between 24.99 � 4.24 to 66.32 � 2.58 q ha-1 and 22.50 � 0.55 to 50.37 � 1.07 q ha-1 in Ist year grown rice and wheat, respectively. Among all the treatments, T3 (100% recommended dose of fertilizer (RDF) + 30 t ha-1 SS) recorded a significantly highest grain yield of rice crop (66.32 and 63.37 q ha-1 ) and wheat crop (50.37 and 46.91 q ha-1 ) during 2015-16 and 2016-17 years, respectively. The straw yield in Ist rice and Ist wheat ranged between 55.11 to 81.22 q ha-1 and 35.86 to 56.62 q ha-1, whereas straw yield in IInd rice and IInd wheat were noticed between 48.42 to 79.31 q ha-1 and 30.45 to 52.32 q ha-1, respectively. The finding clearly shows that the application of SS significantly enhances the yield of rice-wheat crops, and could be an option to a sustainable use of SS. However, the precautionary measure should be followed before use. In addition, the application of SS also indicates the improvement in soil health and sustainability. � 2021 Federation of Eurasian Soil Science Societies. All rights reserved.

    Insights into the Biosynthesis of Nanoparticles by the Genus Shewanella
    (American Society for Microbiology, 2021) Rajput, Vishnu D.; Minkina, Tatiana; Kimber, Richard L.; Singh, Vipin Kumar; Shende, Sudhir; Behal, Arvind; Sushkova, Svetlana; Mandzhieva, Saglara; Lloyd, Jonathan R.
    The exploitation of microorganisms for the fabrication of nanoparticles (NPs) has garnered considerable research interest globally. The microbiological transformation of metals and metal salts into respective NPs can be achieved under environmentally benign conditions, offering a more sustainable alternative to chemical synthesis methods. Species of the metal-reducing bacterial genus Shewanella are able to couple the oxidation of various electron donors, including lactate, pyruvate, and hydrogen, to the reduction of a wide range of metal species, resulting in biomineralization of a multitude of metal NPs. Singlemetal- based NPs as well as composite materials with properties equivalent or even superior to physically and chemically produced NPs have been synthesized by a number of Shewanella species. A mechanistic understanding of electron transfer-mediated bioreduction of metals into respective NPs by Shewanella is crucial in maximizing NP yields and directing the synthesis to produce fine-tuned NPs with tailored properties. In addition, thorough investigations into the influence of process parameters controlling the biosynthesis is another focal point for optimizing the process of NP generation. Synthesis of metal-based NPs using Shewanella species offers a low-cost, eco-friendly alternative to current physiochemical methods. This article aims to shed light on the contribution of Shewanella as a model organism in the biosynthesis of a variety of NPs and critically reviews the current state of knowledge on factors controlling their synthesis, characterization, potential applications in different sectors, and future prospects. � 2021 American Society for Microbiology.

    Nano-biochar: A novel solution for sustainable agriculture and environmental remediation
    (Academic Press Inc., 2022) Rajput, Vishnu D.; Minkina, Tatiana; Ahmed, Bilal; Singh, Vipin Kumar; Mandzhieva, Saglara; Sushkova, Svetlana; Bauer, Tatiana; Verma, Krishan K.; Shan, Shengdao; van Hullebusch, Eric D.; Wang, Bing
    Currently, the applications of biochar (BC) in agricultural practices and for environmental remediation purposes have demonstrated multifaceted advantages despite a few limitations. Nano-BC offers considerable opportunities especially for the remediation of hazardous contaminants as well as the improvement of crop productivity. Positive outcomes of nano-BC on soil physico-chemical and biological characteristics have indicated its suitability for agricultural applications. Nano-BC may effectively regulate the mobilization and sorption of important micro- and macro-nutrients, along with the hazardous contaminants including potentially toxic metals, pesticides, etc. Additionally, the sorption characteristics of nano-BC depends substantially on feedstock materials and pyrolysis temperatures. Nevertheless, the conducted investigations regarding nano-BC are in infant stages, requiring extensive field investigations. The nano-enhanced properties of BC on one hand dramatically improve its effectiveness and sustainability, on the other hand, there may be associated with toxicity development in diverse aquatic and/or terrestrial environments. Therefore, risk assessment on soil organisms and its indirect impact on human health is another area of concern linked with the field application of nano-BC. The present review delineates the potentiality of nano-BC as an emerging sorbent for sustainable agriculture and environmental applications. � 2022 Elsevier Inc.

    Sustainable approach and safe use of biochar and its possible consequences
    (MDPI, 2021) Jatav, Hanuman Singh; Rajput, Vishnu D.; Minkina, Tatiana; Singh, Satish Kumar; Chejara, Sukirtee; Gorovtsov, Andrey; Barakhov, Anatoly; Bauer, Tatiana; Sushkova, Svetlana; Mandzieva, Saglara; Burachevskaya, Marina; Kalinitchenko, Valery P.
    Biochar is considered as a potential substitute for soil organic matter (SOM). Considering the importance of biochar, the present review is based on the different benefits and potential risks of the application of biochar to the soil. Biochar addition to low organic carbon soils can act as a feasible solution to keep soil biologically active for the cycling of different nutrients. The application of biochar could improve soil fertility, increase crop yield, enhance plant growth and microbial abundance, and immobilize different contaminants in the soil. It could also be helpful in carbon sequestration and the return of carbon stock back to the soil in partially combusted form. Due to the large surface area of biochar, which generally depends upon the types of feedstock and pyrolysis conditions, it helps to reduce the leaching of fertilizers from the soil and supplies additional nutrients to growing crops. However, biochar may have some adverse effects due to emissions during the pyrolysis process, but it exerts a positive priming effect (a phenomenon in which subjection to one stimulus positively influences subsequent stimulus) on SOM decomposition, depletion of nutrients (macro-and micro-) via strong adsorption, and impact on soil physicochemical properties. In view of the above importance and limitations, all possible issues related to biochar application should be considered. The review presents extensive detailed information on the sustainable approach for the environmental use of biochar and its limitations. � 2021 by the authors. Licensee MDPI, Basel, Switzerland.
