PublicationArticle A NOVEL METHOD OF DEVELOPMENT OF THE LATENT FINGERPRINTS BASED ON THE POROSITY OF SILICEOUS ROCK POWDER CONTAINING FELDSPAR, BIOTITE AND ALBITE(Medico Legal Society, 2022) Verma, Rahul; Prakash, Satya; Agrawal, Shalvi; Pandey, AsthaBackground: Since ancient history, rock powder has been used in the commission of crime due to their widespread availability. The general sensation, even in the professional fingerprint area is that rock powder does not yield identifiable latent fingerprints. The author of this research paper selects some rocks of siliceous origin (SiO2).The siliceous rock powders have different process of formation and internal texture. Their mechanical adhesion, porosity and lustrous properties help to develop latent fingerprints. However, the rock powders could be obtained abundantly from the rocks exposed in natural sources containing fine grain of quartz (SiO2), K-feldspar, biotite, muscovite, and flaky minerals. The particle size of rock powders is obtained as fine dust of -100 to -120 mesh size. Result: The small particle size results in easy adherence to the oily components of the perspiration of the latent fingerprints. Developed fingerprints have demonstrated better appearance on some contrast surfaces than bright surfaces. In the present study, rock powder of dolerite and granite gneiss of the igneous clans and phyllite and quartzite of the metamorphic clan (high content of silicate minerals) demonstrated best results. However, rock powders of sedimentary origin such as glauconite sandstone have not produced any good result. Conclusion: Based on previous applications in forensic science, few siliceous powders were used for the identification of invisible fingerprints from the crime scene. Also, these are less toxic as compared to metallic powders, eco-friendly (obtained from the natural source as compared to the synthetic powders of chemical origin) and easily available in nature in abundance. The processing cost is very low in preparing it and is economically cheap to meet the requirement of a forensic expert. The rock powders from selected rock can be a good substitute for fingerprint developing powder in being comparatively cheaper than other commercially available powders. � 2022, Medico Legal Society.

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.

The adsorbent was synthesized from an agro waste material. The activated carbon has been characterized by XRD, FTIR, SEM, and surface area. A comparative study of the removal of selected dyes was reported. The process of removal for both the dyes is optimized for important parameters. It has been observed that removal of the dyes is maximum in alkaline range of pH. Both for MB and MG, the removal is controlled by first order kinetics. Mass transfer studies for both the dyes have been reported and the values of coefficient of mass transfer are found to be 2.25�10-5 cm/s and 1.92 cm/s respectively at 30�C. The rates of transfer of dyes onto the adsorbent surface were significant both the cases. The process of removal is endothermic and in both the cases higher temperature favoured the removal. Equilibrium data fitted Freundlich adsorption isotherm and the values of constants are found to be 0.59 and 3.01 mg/g for the removal of selected dyes. The results show suitability of the synthesized material for both the systems and can serve as baseline data for dyes removal. � 2021, National Institute of Science Communication and Information Resources.

But in spite of the relatively high total contents, micronutrient deficiencies have been frequently reported in many crops due to low levels of available micronutrients in soils. Based on the critical limits followed in different states of India, the status of the micronutrients deficiencies was assessed in different soils under the leadership of ICAR All India Coordinated Research Project on Micro- and Secondary Nutrients and Pollutant Elements in Soils and Plants (AICRP-MSPE). In addition to single micronutrient deficiencies, multimicronutrient deficiencies have emerged in different areas of the country over the years, posing a threat to the sustainability of agriculture. Various diagnostic procedures for micronutrients deficiency in soil and plants have been briefly discussed in this paper. In total 1421 field experiments were conducted on specific crops to determine the critical nutrient concentration of different micronutrients. Based on field experiments and crop response to micronutrients, generalized transition zones were worked out for different nutrients across the soil types. Various factors affecting micronutrients availability in soil and deficiency symptoms of micronutrients have been discussed along with their mitigation strategies. Hence this paper represents the current status of micronutrients in Indian soil with emerging solutions for micronutrient deficiency. � 2022 by Nova Science Publishers, Inc.PublicationBook chapter Effect of Conservation Agriculture on Energy Consumption and Carbon Emission(Springer International Publishing, 2022) Mishra, Ajay Kumar; Roohi, R.; Sheoran, Hardeep Singh; Mishra, Sarita; Pandey, Astha; Sah, Diksha; Bhat, Mohammad Amin; Sharma, SheetalConventional agriculture systems with an increased cost of cultivation reduce partial factor productivity, and deterioration of energy, soil, water, and environmental quality threatens food security and aggravates climate change. A holistic package of reduced tillage, residue recycling, crop diversification, and best-bet agronomic practices offered by the conservation agriculture (CA) system seems promising in achieving food security and developing climate resilience in the food production system. This study highlights the overview of CA system, global and national status of CA, opportunities and constraints in adoption of CA, resource efficiencies, particularly energy budgeting in CA, the scope of climate resilience and greenhouse gas emissions (GHGs) mitigation through CA adoption, indices of soil health and carbon sequestration potential under CA systems, and prospects and critical areas of research for scaling of CA systems. Synergies and trade-offs need to be precisely taken care of for need-based site-specific redesigning of CA systems for assured farmer�s income, ecological services, and sustainable development. � The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022, Corrected Publication 2022.PublicationArticle Effect of Nano-Phosphorus Formulation on Growth, Yield and Nutritional Quality of Wheat under Semi-Arid Climate(MDPI, 2023) Poudel, Anuj; Singh, Satish Kumar; Jim�nez-Ballesta, Raimundo; Jatav, Surendra Singh; Patra, Abhik; Pandey, AsthaAppropriate phosphorus (P) management techniques increase yield and nutritional properties while minimizing environmental concerns. The widespread use of nano-fertilizers (NFs) in agriculture endangers soil and plants. It is vital to research the behavior of nano-phosphors (nano-P) on plant growth and quality, as well as their technique of interaction with soil properties in order to obtain key ecosystem benefits. With this in mind, a field experiment was conducted using wheat as a test crop to explore the impact of nano phosphorus (nano-P) on soil. The study�s goal was to examine how the foliar application of nano-P to wheat affects its growth, yield and nutrient concentration. Treatments consisted of: T1: 100% NPK (120:137:72 kg N:P2O5:K2O ha?1) by RDF (recommended dose of fertilizer); T2: 100% NPK by RDF + 2 foliar sprays of nano-P @ 494.21 mL ha?1; T3: 100% NK + 0% P (no foliar); T4: 100% NK + 75% P + 2 foliar sprays of nano-P @ 494.21 mL ha?1; T5: 100% NK + 50% P + 2 foliar sprays of nano-P @ 494.21 mL ha?1;T6: 100% NK + 0% P + 2 foliar sprays of nano-P @ 494.21 mL ha?1; T7: 100% NPK by RDF + 1 foliar spray of nano-P @ 494.21 mL ha?1; T8: 100% NK + 75% P + 1 foliar spray of nano-P @ 494.21 mL ha?1; T9: 100% NPK + 1 foliar spray of nano-P @ 494.21 mL ha?1; T10-100% NK + 75% P + 1 foliar spray of nano-P @ 494.21 mL ha?1. According to the findings, applying 100% NK + 75% P + 2 foliar applications of nano-P at the tillering and panicle initiation stages increased yield over 100% RDF by 37.1%. Additionally, the highest micronutrient concentration (Zn (36.4 mg kg?1), Cu (21.2 mg kg?1), Mn (22.9 mg kg?1) and Fe (61.1 mg kg?1)) in grain were noticed in T3 (100% NK + 0% P no foliar spray of nano-P) treatment, which was superior to T1 (100% NPK). Furthermore, foliar application of nano-P fertilizer in combination with different levels of diammonium phosphate (DAP) slightly increased the amount of N, P and K, as well as micronutrients in post-harvest soil. In summary, the use of 100% NK + 75% + 2 foliar applications of nano-P saved 25% recommendation dose P if supplied as nano-P as a form of phosphorus, and can be a suitable substitute for DAP, especially in smart agriculture, as it possibly reduces P leaching into groundwater, while maintaining or increasing wheat crop yield over the 100% RDF. � 2023 by the authors.PublicationArticle Effect of Ni and Fe Co-Application on the Soybean Crop Grown in Nickel and Iron Deficient Soils of Mirzapur District(Taylor and Francis Ltd., 2024) Bahuguna, Ayush; Singh, Satish Kumar; Pandey, Astha; Sharma, Sachin; Pradhan, Surajyoti; Arvind; Shukla, Munesh Kumar; Bharteey, Prem Kumar; Mukherjee, Sayon; Tripathi, Sumit; Singh, PavanConsidering 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.PublicationBook chapter 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 SinghThe 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.PublicationBook chapter 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 SinghIn 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.
