          Abstract

          A compreensão sobre a biologia de plantas daninhas pode contribuir significativamente no estabelecimento de estratégias adequadas para seu manejo, além de possibilitar o desenvolvimento de ferramentas de controle não químico. O objetivo deste trabalho foi estudar o efeito de profundidade de semeadura, tipo de solo, tipo e quantidade de palha na emergência de plântulas de Vernonia ferruginea (assa-peixe). No primeiro experimento, sementes da espécie foram colocadas em dois substratos (terra e areia) e em sete profundidades (0; 0,0025; 0,005; 0,01; 0,02; 0,04; e 0,08 m). No segundo experimento, determinou-se o efeito de palha de cana-de-açúcar, capim-braquiária e milho em cinco quantidades (0,0; 1,5; 3,0; 6,0; e 9,0 t ha-1) na emergência de V. ferruginea. Maior emergência foi obtida na superfície e em 0,0025 m em ambos os substratos. A palha de milho foi a que mais inibiu a emergência de V. ferruginea, em todas as quantidades testadas.

          Translated abstract

          Basic information on the biology of weeds can contribute significantly to building appropriate strategies for their management, and developing non-chemical control tools. The aim of this work was to study the effect of sowing depth, soil type, and litter type and amount on the emergence of Vernonia ferruginea seedlings. In the first experiment, seeds of this species were placed in two substrates (soil and sand) at seven depths (0, 0.0025, 0.005, 0.01, 0.02, 0.04 and 0.08 m). In the second experiment, the effect of sugarcane straw, signal grass and maize was determined in five amounts (0.0, 1.5, 3.0, 6.0 and 9.0 t ha-1) on the emergence of V. ferruginea. The highest emergence was observed on the surface and at 0.0025 m in both substrates. Corn straw inhibited emergence of V. ferruginea the most, in all the amounts tested.
