Assessing the Influence of Nano Urea on the Growth and Yield of Irrigated Wheat (Triticum aestivum L.) Crop

Wheat (Triticum aestivum L.) is one of the world's most essential cereal crops, serving as a staple food for a significant portion of the global population. In the pursuit of achieving higher yields in contemporary agriculture, the use of chemical fertilizers poses an increased environmental risk. However, the application of Nano urea offers a potential solution to mitigate this risk to a certain extent. To address this objective, a field experiment was conducted during the Rabi seasons of 2022-2023 at the A trial was executed in the rural area of Kanpur district of Mandhana, located 10 km from Kanpur in Uttar Pradesh, during the Rabi season of 2022-23. The experimental design involved two main factors: Factor-1 Nitrogen (at 50%, 75%, and 100% levels) and Factor-2 Foliar Spray (at one time Nano urea and two time Nano urea, with 4 ml/l). A control group was included, and the experiment was laid out in a Randomized Block Design (RBD) with 13 treatments in three replications. The results indicated that the combination of 100% nitrogen along with a foliar spray of 4 ml/L Nano urea had a significant positive impact on growth, yield, and various yield parameters. Treatment 6 demonstrated the highest values for plant height (95.66 cm), Dry matter accumulation (1014.09 g m-2), number of tillers m-2 (417.44), Leaf area index at 90 DAS (4.85), effective ear head per (m-2) (282.66), grains per ear head (65.75), test weight (48.52 g), grain yield (46.15 quintals/ha), and straw yield (57.92 quintals/ha). The study's results demonstrated a generally positive effect of combined Nano urea with traditional NPK nutrient supply on the growth and yield parameters of wheat in irrigated conditions

Efficient Use of Nano-fertilizer for Increasing Productivity and Profitability along with Maintain Sustainability in Rice Crop: A Review

The need for food and the expanding global population have put enormous pressure on agriculture to increase crop yield while preserving sustainability. Since rice is a staple diet for millions of people, novel methods are needed to increase yields without harming the environment. The possible advantages of using nano fertilizers in rice farming are examined in this abstract in order to raise yields, increase farmer profitability, and ensure long-term sustainability. Nano-sized carriers created for effective nutrient delivery to crops are called nano fertilizers, an innovative application of nanotechnology in agriculture. Their special qualities, such as their large surface area and regulated release mechanisms, allow for the targeted supply of nutrients to rice plants, improving nutrient uptake and utilization. Nano-fertilizers successfully optimize nutrient availability as a consequence, increasing crop output. According to studies, using nano fertilizers in rice farming increases grain yields because plants are better able to absorb and assimilate nutrients. The crop's resistance to environmental challenges and disease strains is strengthened as a result of this enhanced nutrient utilization, which also boosts yield and contributes to sustainable rice farming practices. Furthermore, nano fertilizers offer cost-effectiveness and increased profitability for farmers. Despite their initial higher cost, the efficient nutrient delivery of nano fertilizers reduces the overall application rate required compared to conventional fertilizers. This reduction in input costs translates to improved profitability for farmers, promoting economic sustainability in rice production

An Investigation into the Impacts of Preparatory Tillage and Nutrient Management on Barley Yield and Economic Viability in the Context of Water Stress Conditions

A number of field tests were carried out at the Chandra Shekhar Azad University of Agriculture and Technology's Soil Conservation and Water Management Farm in Kanpur, Uttar Pradesh, during the successive rabi seasons of 2020–21 and 2021–22. The gangatic alluvial soil in the study area had a pH of 7.6, which was indicative of its light texture and moderate soil fertility. The study included three different treatments that included preparatory tillage techniques: T1 treatment was one cross plowing with a cultivator; T2 treatment was one disc harrow plowing followed by another cross plowing with a cultivator; and T3 treatment was one disc harrow plowing plus one rotavator pass. The experiment also looked into three different nutrient management strategies: N1, which involved applying 100% of the Recommended Dose of Fertilizers (RDF)—60 kg of N, 30 kg of P2O5, and 30 kg of K2O—through chemical fertilizers; N2, which involved applying 75% of the RDF through chemical fertilizers along with 25% of Farm Yard Manure (FYM); and N3, which applied 50% of the RDF through chemical fertilizers along with 50% of FYM. In addition to applying 50% RDF through chemical fertilizers combined with 50% FYM, the results of the two-year experiment showed that planting barley crops in plots that received one disc harrow plowing and one rotavator pass yielded the maximum values across growth factors, yield attributes (such as grain yield q ha-1, straw yield q ha-1, biological yield q/ha, as well as harvest index), net return, gross return, and the barley benefit-to-cost ratio. This was noted in both years in a consistent manner. The next best results were seen with preparatory tillage, which involved using a cultivator to plough a single cross and applying chemical fertilizers to achieve 100% RDF (N1: 60 kg N ha-1 + 30 kg P2O5ha-1 + 30 kg K2Oha-1)

Sunset Yellow protects against oxidative damage and exhibits chemoprevention in chemically induced skin cancer model

Abstract Skin cancer and other skin-related inflammatory pathologies are rising due to heightened exposure to environmental pollutants and carcinogens. In this context, natural products and repurposed compounds hold promise as novel therapeutic and preventive agents. Strengthening the skin’s antioxidant defense mechanisms is pivotal in neutralizing reactive oxygen species (ROS) and mitigating oxidative stress. Sunset Yellow (SY) exhibits immunomodulatory characteristics, evidenced by its capacity to partially inhibit the secretion of proinflammatory cytokines, regulate immune cell populations, and modulate the activation of lymphocytes. This study aimed to investigate the antioxidant and anti-genotoxic properties of SY using in-silico, in vitro, and physiochemical test systems, and to further explore its potential role in 7,12-dimethylbenz(a) anthracene (DMBA)/ 12-o-tetradecanoylphorbol-13-acetate (TPA)-induced two-stage skin carcinogenesis. In vitro experiments showed that pre-treatment of SY significantly enhanced the cell viability of HaCaT cells when exposed to tertiary-Butyl Hydrogen Peroxide (tBHP). This increase was accompanied by reduced ROS levels, restoration of mitochondrial membrane potential, and notable reduction in DNA damage in (SY + tBHP) treated cells. Mechanistic investigations using DPPH chemical antioxidant activity test and potentiometric titrations confirmed SY’s antioxidant properties, with a standard reduction potential ( $${E}^{o}$$ E o ) of 0.211 V. Remarkably, evaluating the effect of topical application of SY in DMBA/TPA-induced two-step skin carcinogenesis model revealed dose-dependent decreases in tumor latency, incidence, yield, and burden over 21-weeks. Furthermore, computational analysis and experimental validations identified GSK3β, KEAP1 and EGFR as putative molecular targets of SY. Collectively, our findings reveal that SY enhances cellular antioxidant defenses, exhibits anti-genotoxic effects, and functions as a promising chemopreventive agent
