| O presente trabalho teve por objetivo avaliar a eficiência de diversos herbicidas no controle de plantas voluntárias de soja. O experimento foi conduzido em casa de vegetação, onde as unidades experimentais foram compostas de vasos de 10 dm3 de capacidade, dispostos em delineamento inteiramente casualizado em esquema fatorial 2 x 12, com quatro repetições. As cultivares Conquista e Valiosa RR® foram submetidas à aplicação dos herbicidas: atrazine (1.500 g ha-1), tembotrione (100 g ha-1), mesotrione (120 g ha-1), nicosulfuron (40 g ha-1), 2,4-D (670; 1.050 e 1.340 g ha-1), diquat (300 g ha-1), paraquat (400 g ha-1), [paraquat + diuron] (500 + 250 g ha-1) e glyphosate (1.500 g ha-1), além de uma testemunha sem aplicação. A aplicação foi realizada quando as... |

| Abstract: The succession of soybean/maize has been largely adopted. Storm damage and crop problems can lead to grain loss, generating maize ear fragments or even whole ears that remain in the soil and still display germination viability, resulting in the occurrence of volunteer plants. In this context, the present study aimed to evaluate the interference of voluntary maize plants on soybean and investigate the susceptibility of maize hybrids to pre-emergence herbicides. In the first step, an experiment was performed evaluating the influence of voluntary maize plant density and spatial distribution on soybean. The experiment was performed in a randomized completely block design (RCBD) with four replications, with treatments disposed in factorial arrangement... |

| ABSTRACT: This study evaluated the relative competitiveness of two common bean cultivars in coexistence with volunteer corn emerging at different times in different proportions of plants in the association. Firstly, for both beans and volunteer corn, the plant population was determined in which the final production of dry biomass becomes constant (24 plants pot-1). A completely randomized experiment design, with five replicates, was carried out in a 2×2×5 factorial scheme, involving two common bean cultivars (IPR Gralha and Fepagro Triunfo), two emergence times of volunteer corn plants (-7 and 0 days in relation to beans) and five proportions of plants in the association (100:0, 75:25, 50:50, 25:75 and 0:100). At 35 days after bean emergence, measurements... |
