(commonly known as Ajwain Patta) is an important aromatic plant valued for its essential oils, which possess notable therapeutic properties and substantial commercial relevance in the food and cosmetic industries. The present study evaluates the foliar application of Nano NPK fertilizer (nitrogen, phosphorus, and potassium 19:19:19) and its efficacy in improving the agronomic performance of <em>C. aromaticus</em>. Three concentrations (2, 4, and 6 g L⁻¹) of Nano NPK were applied to the foliage of <em>C. aromaticus</em>, resulting in significant improvements in various growth traits and physiological parameters. These included enhanced photosynthetic efficiency, increased levels of photosynthetic pigments (chlorophyll <em>a</em>, chlorophyll <em>b</em>, and carotenoids), elevated nitrate reductase (NR) activity, accumulation of secondary metabolites, and increased essential oil (EO) content and yield. The optimum concentration of Nano NPK (6 g L⁻¹) resulted in a 31.4 % increase in NR activity and 49.1 % and 51.7 % increases in total phenolic and flavonoid content, respectively, compared to the control plants. Furthermore, essential oil content and yield increased markedly by 140 % and 234 %, respectively, under this treatment, demonstrating that Nano NPK effectively stimulates secondary metabolism in medicinal plants. Overall, the findings indicate that foliar supplementation with Nano NPK fertilizer significantly enhances plant growth and physiological functions, while also offering a sustainable and efficient strategy to boost essential oil production in <em>C. aromaticus</em>, thereby increasing its commercial potential.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"12 ","pages":"Article 100160"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144229519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These properties have been instrumental in addressing the drawbacks of conventional fertilizers. While NFs began to be synthesized in early 2000s, emphasis was laid on synthesis of inorganic NFs during 2010–2020. In the past decade, there have been advancements in the methods of NF synthesis, such as synthesis of metal and metal oxide NFs; synthesis of nano-composites using hydroxyapatite (HA), silica, zeolite and graphene oxide; loading of nutrients onto layered double hydroxides, and chitosan; synthesis of chelated NFs; synthesis of 2-D nano-formulations and 2-D NFs; synthesis of organic NFs using biopolymers and agricultural waste; and synthesis of nano-biofertilizers. This review primarily explores these recent advancements for targeted nutrient delivery within plants and their mechanisms of action, potential of NFs to ameliorate stress such as drought, salinity and metal toxicity to improve crop yield, and factors affecting NFs facilitated nutrient delivery. An integrated approach that uses conventional fertilizers along with NFs, tailor-made for different soil types, and use of artificial intelligence to regulate the release of fertilizers would be an ideal approach to improve plant health and increase yield, with minimal environmental impact.

In recent years, nanotechnology has been applied to mitigate the harmful effects of salt stress on various plant species. Nanoparticles are compounds with one or more dimensions between 1 and 100 nanometers and differs from their bulk material counterparts. Previous studies have shown that nanoparticles including Selenium can be applied to mitigate the harmful effects on various plant species. Therefore, the present study aims to evaluate the efficacy of Selenium nanoparticles (SeNPs) in mitigating salinity stress in faba bean. To investigate this, we exposed faba beans plants with three different salt concentrations (0 mM, 40 mM, and 80 mM of NaCl) then treated it with foliar sprays of SeNPs at three varying concentrations (0 ppm, 5 ppm, and 10 ppm). Under salinity stress the faba beans plants were observed to be significantly impaired in plant growth and photosynthetic activity. Furthermore, increased levels of malondialdehyde (MDA) in faba beans exposed to salinity indicated significant cellular damage. However, the application of SeNPs under salinity conditions enhanced plant height and chlorophyll content compared to the control. SeNPs also boosted the activity of key antioxidant defense enzymes, including catalase (CAT), ascorbic peroxidase (APX), and polyphenol oxidase (PPO). In addition, they decreased MDA levels and increased proline and phenol concentrations. These findings suggest that SeNPs improved plant health and vitality by mitigating oxidative stress caused by salt. In conclusion, applying SeNPs spray effectively reduced the harmful effects of salt stress on faba bean plants.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"12 ","pages":"Article 100158"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143927654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
