Influência de doses de fertilizantes foliares nos componentes de produtividade e qualidade de sementes de soja

Abstract

Soybeans became the oilseed that had the highest growth in Brazil, becoming one of the main pillars in the representation of agriculture in the economy, with great modernization in several segments that have been growing year after year and improving according to the demands made by the market. With great growth in research in the search for innovative technologies in sustainable management while preserving the environment. Therefore, the brown algae (Ascophyllum nodosum) is used as a fertilizer for several crops, due to its varied composition and high concentration of nutrients, research must be carried out with the objective of analyzing whether it would become a viable alternative for soybean production. The experiment was carried out in Chapecó, in the west of Santa Catarina, from November 2020 to April 2021. The experimental design was carried out in randomized blocks with 16 treatments and 4 replications per treatment. The number ofwere evaluated pods per plant, plant height, number of grains per pod, Kg/ha yield, 1000 grain weight, vigor and germination. The results obtained showed that the use of extracts did not show significant results to the point of becoming economically viable, improving plant health and production
