| La información experimental del presente trabajo se obtuvo al evaluar en una localidad tres variedades de fríjol (Phaseolus vulgaris L.) de las cuales se encuentra la variedad Canario -107 como precoz, la variedad Negro – Chapingo como intermedia y la variedad Negro – 150 como tardío. El rendimiento depende de componentes que surgen del ciclo biológico de la variedad, de la arquitectura de la planta, de las características de la vaina y también de las cualidades del grano por semilla. Aunque todos los componentes participan en el rendimiento de la planta, no todos son de la misma magnitud, ni reciben el mismo daño cuando el cultivo compite con malezas adaptadas a la región. Para conocer la magnitud de estos efectos, durante el ciclo agrícola del 2006, se... |

| Abstract Non-indigenous plants exhibit different attributes that make them aggressive competitors with indigenous plants and serious threats to biodiversity.Senecio madagascariensis (fireweed, Asteraceae), a native from southern Africa, is a strong competitor in agricultural activities and has toxic alkaloids that may result in high cattle mortality. In Brazil, this weed was collected for the first time in 1995 and has since spread quickly throughout the Pampas region. To better understand the invasion of the fireweed in South America, we used a genetic characterization with internal transcribed spacer (ITS) and microsatellite markers. Based on the ITS data, the southern Brazil populations of S. madagascariensis shared genetic homology with samples taken... |

| ABSTRACT Herbicide tolerance differs among potato cultivars. Thus, pre-emergence herbicides in potatoes need to be studied. We evaluated weed control, selectivity and potato yield of cv. Innovator with the herbicides clomazone, metribuzin and linuron. The experimental design was randomized blocks with four replications. One experiment was installed in 2014 (experiment 1, 5 treatments) and another in 2015 (experiment 2, 7 treatments), irrigated by central pivot in Perdizes-MG, Brazil. In experiment 1 treatments consisted of a control (T1), a hoed control (T2), clomazone (360 g ha-1) (T3), metribuzin (480 g ha-1) (T4), and linuron (990 g ha-1) (T5). The treatments in experiment 2 repeated those in experiment 1 (T1 to T5) and added clomazone + metribuzin (360... |
