The Impacts of Different Application Methods, Concentrations, and Stages of Selenium on Crops

A naturally occurring metalloid selenium (Se) has been shown to be a necessary trace element for both humans and animals. There is a complex relationship between Se and crops, with both promoting inhibitory effects, which could be connected to variations in Se application methods, application concentrations, and application stages. Recently, Se has received a great deal of attention because of its significance and contradictory nature. This review compiles the main literature results of the impacts of different application methods, concentrations, and stages of Se on crops, examining how various plant species respond to Se and how they interact with abiotic stress. It is anticipated that this will demonstrate the viability and benefits of Se biofortification for various crop requirements and will be favorable to increasing the range of applications for Se biofortification.
