“…In conventional agriculture, extensive chemical fertilisers are used to obtain high yields for commercial purposes [82,88]. At present, nanotechnology is of growing interest in plant nutrition in conventional agriculture [89,90]. Nano fertilisers are being introduced, focusing on P fertilisers, as most farmlands are P deficient [91].…”

Urban agriculture plays a vital role in ensuring the self-sufficiency of a great variety of fresh vegetables and nutrients. It promotes a sustainable food system as well as reducing the dependency on imports for the growing population. Urban farming has made it possible for agriculture practices to be implemented anywhere at any time in a sophisticated way. Hydrogel has been introduced in urban agriculture in the past few decades. However, the application of hydrogel in urban agriculture is still being explored in terms of hydrogel types, structure, physical and chemical properties, change due to external factors, and its suitability for different plant species. This review discusses the potentials and limitations of hydrogel in different application conditions. We present the state of knowledge on hydrogel production and crosslinking methods, hydrogel characteristics, water absorption and release mechanisms of hydrogel, hydrogel advantages and limitations, and current and future applications in urban farming.

“…The chemical pesticides and fertilizers adversely affect ecosystems and human health, particularly when large doses are used to increase plant yield. Therefore, it has become desirable to replace conventional pesticides and fertilizers with nanopesticides and nanofertilizers, to reduce the use of chemical fertilizers, increase plant yield, and support agricultural development ( Bratovcic et al, 2021 ). Thus, these nanopesticides and nanofertilizers are now receiving increasing research attention ( Kah, 2015 ).…”

Plants are subjected to a wide range of abiotic stresses, such as heat, cold, drought, salinity, flooding, and heavy metals. Generally, abiotic stresses have adverse impacts on plant growth and development which affects agricultural productivity, causing food security problems, and resulting in economic losses. To reduce the negative effects of environmental stress on crop plants, novel technologies, such as nanotechnology, have emerged. Implementing nanotechnology in modern agriculture can also help improve the efficiency of water usage, prevent plant diseases, ensure food security, reduce environmental pollution, and enhance sustainability. In this regard, nanoparticles (NPs) can help combat nutrient deficiencies, promote stress tolerance, and improve the yield and quality of crops. This can be achieved by stimulating the activity of certain enzymes, increasing the contents (e.g., chlorophyll) and efficiency of photosynthesis, and controlling plant pathogens. The use of nanoscale agrochemicals, including nanopesticides, nanoherbicides, and nanofertilizers, has recently acquired increasing interest as potential plant-enhancing technologies. This review acknowledges the positive impacts of NPs in sustainable agriculture, and highlights their adverse effects on the environment, health, and food chain. Here, the role and scope of NPs as a practical tool to enhance yield and mitigate the detrimental effects of abiotic stresses in crops are described. The future perspective of nanoparticles in agriculture has also been discussed.

“…They have a wide range of applications; however, they are most commonly employed as nanofertilizers and antibacterial agents. 42 They are also beneficial because of their low cost and eco-friendliness, and they have been proven helpful in antibacterial activity due to their surface chemical action. Some of them demonstrated excellent outcomes in developing antioxidant profiles in watermelon seedlings and helped to improve Chl content.…”
