Monitoring plant growth and development during cultivation to optimize resource use efficiency is crucial to achieve an increased sustainability of agriculture systems and ensure food security. In this study, we compared field monitoring approaches from the macro to micro scale with the aim of developing novel in vivo tools for field phenotyping and advancing the efficiency of drought stress detection at the field level. To this end, we tested different methodologies in the monitoring of tomato growth under different water regimes: (i) micro-scale (inserted in the plant stem) real-time monitoring with an organic electrochemical transistor (OECT)-based sensor, namely a bioristor, that enables continuous monitoring of the plant; (ii) medium-scale (<1 m from the canopy) monitoring through red–green–blue (RGB) low-cost imaging; (iii) macro-scale multispectral and thermal monitoring using an unmanned aerial vehicle (UAV). High correlations between aerial and proximal remote sensing were found with chlorophyll-related indices, although at specific time points (NDVI and NDRE with GGA and SPAD). The ion concentration and allocation monitored by the index R of the bioristor during the drought defense response were highly correlated with the water use indices (Crop Water Stress Index (CSWI), relative water content (RWC), vapor pressure deficit (VPD)). A high negative correlation was observed with the CWSI and, in turn, with the RWC. Although proximal remote sensing measurements correlated well with water stress indices, vegetation indices provide information about the crop’s status at a specific moment. Meanwhile, the bioristor continuously monitors the ion movements and the correlated water use during plant growth and development, making this tool a promising device for field monitoring.

“…Pesticides are commonly used to combat insect and weed damage in crops, but their use is not species-specific [ 105 ]. Thus, concerns about environmental threats associated with their exposure [ 105 ], their toxicity to other organisms, and their ability to contaminate soil, water, grass, and other vegetation are important to note [ 106 , 107 ], in addition to their tendency to induce root dieback in plants [ 108 , 109 ]. Recently, the application of nanotechnologies has been proposed to reduce the damage associated with the use of chemical substances, offering, at the same time, the prospect of increased productivity through the adoption more sustainable agricultural practices [ 109 ].…”

Although different nanoparticles have already been developed, the research trend is moving towards the development of biodegradable and biocompatible systems that can reduce the effects of the toxicity of metal-based products and enhance the green nanotechnological processes; this could lead to increased energy efficiency, and increase practices of implementing bio-compatible and non-toxic solvents and reliance on natural sources, including plants, algae, animals, and microorganisms [ 105 , 108 , 110 , 111 ].…”

Nanomaterials, due to their unique structural and functional features, are widely investigated for potential applications in a wide range of industrial sectors. In this context, protein-based nanoparticles, given proteins’ abundance, non-toxicity, and stability, offer a promising and sustainable methodology for encapsulation and protection, and can be used in engineered nanocarriers that are capable of releasing active compounds on demand. Zein is a plant-based protein extracted from corn, and it is biocompatible, biodegradable, and amphiphilic. Several approaches and technologies are currently involved in zein-based nanoparticle preparation, such as antisolvent precipitation, spray drying, supercritical processes, coacervation, and emulsion procedures. Thanks to their peculiar characteristics, zein-based nanoparticles are widely used as nanocarriers of active compounds in targeted application fields such as drug delivery, bioimaging, or soft tissue engineering, as reported by others. The main goal of this review is to investigate the use of zein-based nanocarriers for different advanced applications including food/food packaging, cosmetics, and agriculture, which are attracting researchers’ efforts, and to exploit the future potential development of zein NPs in the field of cultural heritage, which is still relatively unexplored. Moreover, the presented overview focuses on several preparation methods (i.e., antisolvent processes, spry drying), correlating the different analyzed methodologies to NPs’ structural and functional properties and their capability to act as carriers of bioactive compounds, both to preserve their activity and to tune their release in specific working conditions.

Nitrogen, despite being essential for the growth of plants, can pose serious threats to the ecological environment when applied excessively as fertilizers. The application of nanomaterials has a catalytic effect on crop growth and a restorative effect on the environment. However, their effect on mitigating ammonium stress in crops is poorly understood. In the present study, the roles of nanoparticles of magnesium oxide (nMgO) and hydroxyapatite (nHA) with different application rates (0, 10, 100, 500, and 1000 mg L−1) on seed germination and seedling growth in water spinach (Ipomoea aquatica Forssk.) and Hami melon (Cucumis melo L.) were investigated, and the ammonium stress mitigating capacity of nanoparticles with the optimal application rate on the two crops was analyzed. The results showed that the application of nMgO and nHA at an optimal rate of 100 mg L−1 significantly promoted seed germination of water spinach, followed by the increase of germination potential, seed germination rate, and germination index, while alleviating the inhibitory effect of NH4+ stress in water spinach. As for the Hami melon, nHA reduced the ammonium stress on seedlings by promoting antioxidant enzyme activity, while nMgO was found to be involved in reducing the root growth of Hami melon seedlings. This study provided a reference on how to select the appropriate type and optimize the application method of nanomaterials that will be used in agriculture in the future.
