Interferência das plantas daninhas no feijoeiro carioca

Abstract: RES UMO -Este tra balho foi rea liz ado com o objetivo de deter minar os perío dos de interferência das plantas daninhas na cultura do feijoeiro (Phaseolus vulgaris) plantado em janeiro. A semeadura do cv. Carioca foi feita no sistema convencional e os tratamentos constaram de dois grupos: no primeiro, a cultura do feijão permaneceu livre da interferência das plantas daninhas desde a emergência até 10, 20, 30, 40, 50, 60 e 70 dias (todo o ciclo da cultura); no segundo, a cultura permaneceu sob interferência de… Show more

“…Santi et al (2014), when assessing the phytosociological variability of weeds in a soy tillage area in Boa Vista das Missões, RS, observed that the families Poaceae and Asteraceae were the ones more occurring in the area. However, Cruz et al (2009), in a study carried out in an area rotated with crops of soy, corn and rice, Phytosociological survey of weeds in cultivars of common beans ... Salgado et al (2007), when assessing the interference of weeds in the carioca bean plant, with undetermined growth habit (Type III) in Jaboticabal-SP, obtained weeds composed by 13 species of weeds, 62% of them dicotyledons and 38% of monocots.…”

“…The bean plant has limited competitive capacity with the weeds and, depending on the interference degree imposed by the interaction existing between the weed community and the crop, the environmental factors and the coexistence period, the losses in productivity may range from 35 to 67% (Salgado et al, 2007;Borchartt et al, 2011). Since the bean plant is cultivated throughout the year in different crops and regions in the country, it is interfered by the wide diversity of weeds (Cobucci, 2004).…”

“…Con el aumento del peso seco de las malezas, que alcanzaron valores de 713,1 y 1.122,8 g m -2 a los 80 DDE, los rendimientos disminuyeron para 617,09 y 958,25 kg ha -1 , respectivamente (Figura 4 y Tabla 3). El mismo comportamiento fue verificado por Salgado et al (2007) en el cultivo de frijol en siembra convencional y por Kozlowski et al (2002) en siembra directa. Ambos constataron una disminución acentuada de la producción de frijol cuando él convivió por períodos crecientes con la comunidad de malas hierbas.…”

“…Para el frijol común, la disminución del rendimiento de granos alcanzó 67% (Salgado et al, 2007) en el sistema convencional. Para la siembra directa con residuos vegetales en Figura 4 -Correlación entre peso seco (g m -2 ) de la comunidad infestante al final de los períodos de convivencia y la productividad de granos de frijol (kg ha -1 ) en función de los períodos de convivencia, en la ausencia y presencia de residuos vegetales de crotalaria, siendo y la máxima productividad de granos de frijol; y x la máxima cantidad de peso seco de malezas.…”
