Incidência de inços na cultura da cevada (Hordeum vulgare L.) em diferentes sistemas de cultivo

Abstract

Modern organic agriculture emerged as an alternative to conventional farming, aiming to combat the negative impacts caused by this practice. Therefore, this study sought to evaluate the weed incidence in four barley cultivation systems. The experiment was conducted in the experimental area of the Universidade Federal da Fronteira Sul, Campus Laranjeiras do Sul, Paraná. A randomized experimental design with six blocks and four cultivation systems was used, totaling 24 experimental units. The organic, biodynamic, conventional, and absolute control cultivation systems were employed. The wet weight, dry weight, as well as the treatment efficiency in biomass production and weed control. Additionally, the efficiency of using the knife roller for weed control was also assessed. The obtained results underwent analysis of variance and Tukey's test. There was a statistical difference between the control treatment and the other treatments. There was no statistical difference between the Biodynamic, Organic, and Conventional cultivation systems regarding weed incidence.
