Abstract

Rapidly growing human population, rising anthropogenic pollution of the environment, and climate change increase the demand for crop production to achieve high yields that would provide sufficient quality and healthy food. Essential metals play important roles in maintaining cellular homeostasis and are indispensable for plant development and growth; however, they have adverse effects on crops when applied in excess, similar to nonessential toxic metals. The increasingly widespread application of nanotechnologies in agriculture can appreciably contribute to the improvement of existing crop management techniques and optimization of crop yields, which are of great importance for the nutrition of the population. This contribution comprehensively reviews recent findings related to the beneficial effects of metal- and metalloid-based nanoparticles on crops. Attention is focused on their potential to be used as plant growth-promoting compounds and components of fertilizer preparations and their favorable effects in reducing the harmful impact of abiotic stresses (drought, salinity, flooding and waterlogging, soil acidity, temperature, UV light, elevated CO2, toxic metal pollutants) on plants. The effects of metal-based nanoparticles on crops based on the composition, particle size, particle shape, morphology, surface coating, and concentration of the nanoparticles as well as their mechanism of action are also discussed.
