Levantamento florístico de plantas daninhas na cultura da mandioca no município de Pompéia-SP
| Resumo: | The study of weeds population dynamics based on floristic survey is essential to determine the management methods and ideal periods for establishing control in cassava. The aim of this study was to analyze the weed community in planting sweet cassava in the municipality of Pompéia - SP has been employed the method of square inventory. The sampled area corresponds to 13.1 ha and was divided into grid of 50 X 50 m, totaling 53 points. In each point do was randomly thrown a wooden square with 1m side (1 m2). We evaluated the following parameters: relative frequency, relative density, relative abundance and index of economic importance. Were identified 13 weed species on 9 families and the most important index of economic importance, were Brachiaria decumbens e Digitaria horizontalis So the weeds identified in the survey are considered the most common and problematic the productivity of cassava. |
