The purpose of this experiment was to investigate the effects of salinity (NaCl) on the mineral composition and macro- and micronutrient contents of rice plants. The experiment was conducted at the Department of Biotechnology’s experimental area in SVPUAT Meerut. Various salinity treatments were applied, including T0 (Control), T1 (60 mM NaCl), T2 (80 mM NaCl), T3 (100 mM NaCl), T4 (ZnO NPs 50 mg/L + 60 mM NaCl), T5 (ZnO NPs 50 mg/L + 80 mM NaCl), and T6 (ZnO NPs 50 mg/L + 100 mM NaCl). The results analysis revealed that the micro- and micronutrients in rice genotypes decreased compared to the control treatment. However, when 50 mg/L of ZnO-NPs were applied, the concentrations of both macro- and micronutrient contents in rice plants were found to increase. This is the most significant finding of this research.

The distinctive qualities and wide array of possible applications of nanotechnology have garnered considerable attention. Nanotechnology offers a groundbreaking way for expanding agricultural output that is also ecologically benign, helpful to living things, and economically priced – all without losing quality. There is a growing trend towards using eco-friendly technologies as substitutes for conventional agricultural inputs, such as fertilizers and insecticides. With the aid of nanotechnology, the confines of conventional farming techniques can be overcome. As a result, it becomes essential for investigators to devote their energies to the noteworthy nanoparticles (NPs) in agriculture investigations that have been distributed. It offered a fresh perspective on the development and application of nanoparticles as nano-fertilizers and nano-pesticides in agriculture and a way to heighten bio-factor execution. Furthermore, we discuss the relations of NPs with plants, the perils and putrefaction of nanomaterials in plants, and the utility of NPs in the reduction of stress triggered by heavy metal toxicity and abiotic factors. It is imperative that nano-fertilizers are practiced to reduce the environmental maltreatment caused by conventional, inorganic fertilizers. Nano-fertilizers are more sensitive and have the ability to penetrate the epidermis, empowering them to promote nutrient consumption efficiency while reducing nutrient overabundance. A study found that NPs may cause oxidative stress symptoms in higher plants if they adhere to cell surfaces or organelles. Understanding the benefits and drawbacks of using nano-fertilizers instead of conventional fertilizers is valuable, and it is the purpose of this book chapter to provide this information.

An exciting new window of opportunity has opened up for environmentally responsible farming with the advent of the nanotechnology era: the role of nanoparticles (NPs) to mitigate abiotic stresses. NPs have unique physiochemical characteristics that make them an attractive study subject. Rice growth and yield are severely inhibited by salinity, a major detrimental abiotic factor. However, the impact of NPs on rice seeds germination characteristics and physio-biochemical phenomena under salt stress conditions remains poorly understood. Accordingly, we intended to look at how zinc oxide nanoparticles (ZnO-NPs) affected germination processes and the early seedling stage while the rice plants (Kargi and CSR 30 rice genotypes) were put under salinity stress. Different germination characteristics parameters were considered, e.g., germination percentage (GP) relative seed germination rate (RGR), and seed vigour index (SVI) determined after eight days of treatment with ZnO-NPs at a concentration of 50 mg/L on rice seed. After passing the germination test, the seeds were placed in Hoagland hydroponic solution and given another week of ZnO-NPs treatment to evaluate the seedling growth and phyto-biochemical characteristics, such as shoot height and root length, inhibition percentage of shoot height and root length, chlorophyll and carotenoid stability index, chlorophyll and carotenoid inhibition percentage, malondialdehyde (MAD) content and antioxidant enzymatic activities (SOD, APX).This investigation demonstrated that 50 mg/L ZnO-NPs have the potential to alleviate the effect of salt stress on rice genotypes during the germination stage.

Over the past years, alterations in the environment have had an adverse impact on the global agricultural system, leading to difficulties in plant growth, physiology, and productivity due to non-living factors. These difficulties pose a significant risk to both global food security and agricultural advancement, necessitating innovative methods for long-term sustainability. Nanotechnology has emerged as a promising solution to address these difficulties by utilizing nanoscale products like nanofertilizers, nanofungicides, nanoherbicides, and nanopesticides. Nanoparticles provide distinct advantages in agriculture due to their small size, ability to easily penetrate cellular barriers, and efficient absorption by plants. Numerous studies have demonstrated that the application of nanoparticles can improve both the quantity and quality of crop yields, even when faced with various biological and environmental pressures. This research study primarily focuses on investigating the impact of non-living pressures on plants and examining how nanoparticles can help alleviate these effects. Additionally, it explores the molecular, metabolic, and anatomical adaptations that plants undergo to thrive in challenging environments. Nonetheless, it is essential to acknowledge that the widespread utilization of nanotechnology raises concerns regarding potential risks to the environment and human health.
