Special Issue Information

Dear Colleagues,

At present, the development of agricultural areas is only possible by increasing resource use efficiency with the least harm to the environment and humans through the effective use of modern technologies. Nanotechnology is a scientific field with a number of dimensions. It is concerned with particles ranging in size from 1 to 100 nm, and raises hopes for improving agricultural productivity by addressing problems which were conventionally intractable. High reactive surface area and very small packing space requirements have made the use of nanoparticles popular in both agrochemistry and agriculture.

The present Special Issue of Nanomaterials aims to present the current state-of-the-art use of nanoparticles to improve agricultural productivity, as well as the role of nanoparticles in agrochemicals (herbicides and pesticides). Agrochemicals are key in the transition between crop productivity and losses. In the present Special Issue, we invite contributions from leading groups in the field, with the aim of giving a balanced view of the current state of the art in this discipline.   

As the Guest Editors of this Special Issue of Nanomaterials titled “Advanced Nanotechnology in Agrochemistry and Agriculture”, we invite you to contribute your research articles related to nanotechnology in plants, specifically related to the chemical compositions and changes involved in the production, protection, physiochemical, and molecular physiological levels. Research articles describing ways to improve agricultural productivity are also welcome.

In this Special Issue, both original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Nanoparticles-mediated changes in plants;
  • Nanorods and their applications in agriculture;
  • Nanoparticles in agrochemistry;
  • Abiotic stress and nanoparticles;
  • Nanoparticles in herbicides and pesticides;
  • Plant physiology and agrochemistry.

We look forward to receiving your contributions.

The progressive influx of engineered nanoparticles (ENPs) into the soil matrix catalyses a fundamental transformation in the equilibrium dynamics between the soil and the edaphic solution. This all-encompassing investigation is geared towards unravelling the implications of an array of ENP types, diverse dosages and varying incubation durations on the kinetics governing Cd2+ sorption within Ultisol soils. These soils have been subjected to detailed characterizations probing their textural and physicochemical attributes in conjunction with an exhaustive exploration of ENP composition, structure and morphology. To decipher the intricate nuances of kinetics, discrete segments of Ultisol soils were subjected to isolated systems involving ENP dosages of 20 and 500 mg ENPs·kg−1 (AgNPs, CuNPs and FeNPs) across intervals of 1, 3 and 6 months. The comprehensive kinetic parameters were unveiled by applying the pseudo-first-order and pseudo-second-order models. At the same time, the underlying sorption mechanisms were studied via the intra-particle diffusion model. This study underscores the substantial impact of this substrate on the kinetic behaviours of contaminants such as Cd, emphasizing the need for its consideration in soil-linked economic activities and regulatory frameworks to optimize resource management.

This paper explores the potential of nano seed priming with calcium oxide nanoparticles in maintaining the redox status in carom (Trachyspermum ammi L.) plants by modulating non-enzymatic antioxidants and enzymatic antioxidants. Calcium oxide nanoparticles were prepared in four testing regimes comprising 25, 50, 75, and 100 ppm along with the control treatment of 0 ppm (distilled water). Priming was performed by soaking the carom seeds in the aerated water, and plants were grown under split plots corresponding to drought and water. Seed priming with 75 ppm CaONPs reduced hydrogen peroxide, malondialdehyde contents and electrolyte leakage by 23.3%, 35.9% and 31.6%, respectively, in the water-stressed carom plants. The glutathione s-transferase, superoxide dismutase and peroxidase functions improved under water stress by 42.3%, 24.1% and 44.8%, respectively, in the carom plants raised through 100 ppm primed seeds with CaO_NPs. Priming induced better Ca2+ signaling, which affected the enzymes of the ascorbate glutathione cycle, enabling them to maintain redox status in the carom plants exposed to drought stress. The morpho-agronomic traits of carom plants in terms of number of umbels, hundred seeds weights, shoot and root length and biomass improved significantly upon seed priming treatments. Seed priming with CaO_NPs is a viable strategy to combat reactive oxygen species-mediated damages in the carom plants. Full article

In the current scenario, the rising concentration of heavy metals (HMs) due to anthropogenic activities is a severe problem. Plants are very much affected by HM pollution as well as other abiotic stress such as salinity and drought. It is very important to fulfil the nutritional demands of an ever-growing population in these adverse environmental conditions and/or stresses. Remediation of HM in contaminated soil is executed through physical and chemical processes which are costly, time-consuming, and non-sustainable. The application of nanobionics in crop resilience with enhanced stress tolerance may be the safe and sustainable strategy to increase crop yield. Thus, this review emphasizes the impact of nanobionics on the physiological traits and growth indices of plants. Major concerns and stress tolerance associated with the use of nanobionics are also deliberated concisely. The nanobionic approach to plant physiological traits and stress tolerance would lead to an epoch of plant research at the frontier of nanotechnology and plant biology. Full article
