Tratamento de sementes de soja com produtos à base de fertilizantes e biofertilizantes

Abstract

Most biofertilizers can be applied in the form of sprays on the soil or plant canopy, being applied alone or together with herbicides, or also in seed treatment. The objective of the present work was to evaluate the treatment of soybean seeds with biofertilizers compared to chemical products. The work was conducted in the Didactic Laboratory of Seed Analysis of the Faculty of Agronomy Eliseu Maciel of the Federal University of Pelotas (UFPel), Pelotas-RS. Soybean seeds, cultivar NA 5909, were used. Soybean seeds were treated with insecticide (Cruiser), fungicide (Maxin Advanced), nematicide and biofertilizer (Energy®), all with the recommended doses for the crop. The tests were carried out with and without water stress. Water stress was obtained by means of aqueous solutions of polyethylene glycol (PEG 6000). After the treatments, the following tests were performed: germination test (G%), accelerated aging test (EA%), emergence in soil (E%), emergence speed index (IVE and root length (CR). It was concluded that seed treatment with Energy® biofertilizer confers beneficial changes to soybean plants, with a positive effect on the physiological quality and vigor of the seeds.
