(Elsevier, 2022) Ayush Bahuguna; Sachin Sharma; Ashish Rai; Reshu Bhardwaj; Sanjib Kumar Sahoo; Astha Pandey; Bharti Yadav
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.

Considering the importance of nickel and iron nutrition for the soybean crop, their deficiency inhibits the yield drastically specially in the area where soybean crop is dominant. To encounter this problem, a pot experiment was conducted in glass house on low nickel and iron soil in Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, during 2019–20 and 2021–22. The study was carried out to investigate the effect of Ni (nickel) and Fe (iron) on the post-harvest soil parameters, growth, yield, nutrient uptake and nutrient content of soybean crop. There were 10 treatments with two levels of Ni (5 and 10 mg kg −1) and Fe (10 and 20 mg kg−1) with recommended dosage of fertilizers nitrogen, phosphorus, potassium (8.93, 35.71, and 17.86 mg kg−1) applied to all treatments except control. The result of the experiment revealed that the co-application of nickel and iron@10 mg kg−1 and 20 mg kg−1 (RDF + Ni10Fe20), resulted in the increase in plant height, greeness index, no of seed per pod, no of pod per plant, seed yield, and stover yield. Similar, findings for the post- harvest soil parameter indicated that there was increase in pH, electrical conductivity, and organic carbon content of soil. DTPA (Diethylenetriaminepentaacetic acid) extractable Ni, Fe, Zn, and Cu, also found highest in treatment where nickel and iron@10 mg kg−1 and 20 mg kg−1 (RDF + Ni10Fe20) were applied in soil, but in case of DTPA extractable Mn, the highest amount was found in treatment where nickel and iron@10 mg kg−1 and 10 mg kg−1 (RDF + Ni10Fe10) was applied in soil. The soil microbial biomass carbon and urease activity was also found highest in the treatment where nickel and iron@10 and 20 mg kg−1 was applied in soil. The minimum plant height, greeness index, no of seed per pod, no of pod per plant, seed, and stover yield was recorded in treatment where only RDF(T1) was applied. Similar, result recorded for the post-harvest soil parameters. So, overall findings of the pot experiment revealed that the conjoint application of nickel and iron has resulted in better yield of soybean crop. © 2024 Taylor & Francis Group, LLC.

(Taylor and Francis Ltd., 2023) Sachin Sharma; Ayush Bahuguna; Manoj Parihar; Janardan Yadav; Surendra Singh
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.

(Elsevier, 2024) Ashish Rai; Rahul Mishra; Abhik Patra; Arvind Kumar Singh; Sachin Sharma; A. Arvind; Ayush Bahuguna; Sumit Rai; Jitendra Rajput; Anshu Gangwar; Shankar Jha; Sumit Kumar Tripathi; Rajeev Kumar Srivastava; Dibyanshu Shekhar; Satish Kumar Singh; Tejaswini Kapil; Ram Babu Sharma; Supriya Rai
Microbes and their metabolic activity are crucial for a healthy and functioning soil. The rhizosphere, where plant roots and microbes mingle, is a bustling hub for nutrient cycling, energy flow, and microbial activity. Sustainable farming prioritizes nurturing these rhizospheric processes. Biofertilizers, including symbiotic and nonsymbiotic microbial partnerships, plant growth-promoting microbes, and arbuscular mycorrhizal collaborations, all play diverse roles in soil health and plant growth. Some microbes like Pseudomonas spp., Bacillus spp., and Streptomyces spp. help convert insoluble phosphorus into plant available forms. Composting, is another sustainable process, transforms organic waste into valuable compost, a dual-action fertilizer and soil amendment. Microbes decompose organic matter in compost, turning it into a stable, plant-friendly material. This aerobic process breaks down easy-to-digest molecules, generating CO2 and more durable substances. Composting effectively manages organic waste, reusing nutrients, reducing volume and moisture, and breaking down harmful organics plus, intricate humic-like chemicals form, boosting soil health. Thus, understanding and nurturing the vibrant microbial world in the rhizosphere through sustainable practices like biofertilizers and composting is key to healthy soil and a thriving future for farming. © 2025 Elsevier Inc.

(Springer Science and Business Media Deutschland GmbH, 2022) Ayush Bahuguna; S.K. Singh; Sachin Sharma; Arvind; Astha Pandey; Basant Kumar Dadarwal; Bharti Yadav; Akshita Barthwal; Raghu Nandan Singh Khatana
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.

(Nova Science Publishers, Inc., 2022) Manoj Kumar Chitara; Rajesh Pratap Singh; Prince Kumar Gupta; Dhruv Mishra; Surendra Singh Jatav; Sachin Sharma; Hanuman Singh Jatav
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.
