Uso de aminoácidos e nano partículas de prata e micro partículas de zinco no tratamento de sementes em soja

Abstract

The use of biofertilizers based on amino acids and nanotechnology involving zinc and silver nanoparticles has been studied as a viable alternative to the use of mineral fertilizers and agrochemical products, with a more suitable application from an ecological standpoint. The objective of this study was to evaluate the effect of different doses of an experimental biostimulant and zinc and silver nanoparticles during the early development phase of soybean seeds. The experiments were conducted at the Seed Laboratory of the Foundation for Scientific and Technological Development (FUNDETEC), Cascavel, PR, in the year 2023. For the germination evaluation, a randomized block design was used, comprising 23 treatments with varying doses of amino acid matrix associated and not associated with zinc and manganese, micro zinc compounds, and nano silver compounds. For the assessment of enzymatic activity and protein content, a completely randomized design with 12 treatments was employed. The germination rate, peroxidase enzymatic activity, and protein content of seedlings were evaluated. The use of isolated doses of zinc nanoparticles for soybean treatment, when compared to other treatments, demonstrated more advantages for the early development of the crop, contributing to rapid and uniform germination.
