Durante o ano agricola de 1975/76, estudou-se, em Vicosa, o comportamento de 60 variedades de mandioca, visando a producao de raizes e de ramas e teor de amido. Efetuou-se, ainda, um estudo de caracteristicas da parte aerea e das raizes das variedades. Paralelamente procuraram-se verificar algumas correlacoes entre producao de raizes e as variaveis producao de ramas, diametro do caule a 5cm do solo, altura da planta, largura de ramificacao e altura de ramificacao. O ensaio foi instalado em um solo Podzolico Vermelho Amarelo Cambico, fase terraco, distrofico. Usou-se o delineamento de blocos ao acaso, com tratamentos comuns com 4 repeticoes. As variedades foram divididas em 3 grupos, de acordo com a altura observada antes da retirada da rama para plantio. Nas condicoes em que este ensaio foi realizado, as seguintes conclusoes podem ser tiradas. |

Among the weeds that interfere with the growth and development of sweet sorghum, beggar ticks stands out, because it has a high competitive capacity for the available resources. This study aims to compare the competitive ability of sweet sorghum (Sorghum bicolor (L.) Moench) against hairy beggarticks (Bidens pilosa L.), as a function of cultivar and plant proportion. Experiments were conducted in a greenhouse in a completely randomized design with four replications and six treatments. Treatments were arranged in replacement series in the proportions of 100:0, 75:25, 50:50, 25:75, and 0:100% (sorghum:weed) equivalent to 20:0, 15:5, 10:10, 5:15 and 0:20 plants per pot with 8 dm3 capacity of sweet sorghum (cultivars ?BRS 506?, ?BRS 509? or ?BRS 511?) against hairy beggarticks. Fifty days after emergence, plant leaf area (LA), aboveground dry mass (DM), photosynthesis (A), and transpiration rates (E) were measured. Competitive ability was analyzed by using the graphical analysis method and building diagrams based on total and relative productivity. Competitiveness, clustering coefficient, and aggressiveness were also determined. Sorghum cultivars, in general, showed losses independently of the proportion of hairy beggarticks. Statistical analysis showed small differences in competitive ability among sorghum cultivars; ?BRS 509? was also demonstrated to be slightly more competitive than ?BRS 506? and ?BRS 511? against hairy beggarticks. This, however, is unlikely to provide a competitive advantage for ?BRS 509? in production fields, and hairy beggarticks should be efficiently controlled early in the crop cycle to avoid productivity losses, independently of the sorghum cultiva MenosAmong the weeds that interfere with the growth and development of sweet sorghum, beggar ticks stands out, because it has a high competitive capacity for the available resources.
