Resumo: | In Edéia (GO), many of the farmers who had adopted the no-tillage system complained about the high expenses related to the control of weeds. Due to this problem, this study aimed to quantify the seedlings emergency in the beginning of the rainy season by means of comparison of agro-ecosystems in Edéia. Four of them were chosen: 1) Soy/Corn/Soy/Sorghum/Soy (area I); 2) Soy/Corn/Soy/Sorghum/Soy (area II); 3) Corn/SoylSorghum/Soy; 4) Soy/Soy/Corn/Brachiaria. The results were expressed in population of weeds by m². As far as statistical analysis is concerned, the following groups were established: the main dicotiledoneous species; the main monocotiledeneous species; the species of double cropping; the Brachiaria species. One may infer that the adopted handling in the last two years favoured certain species with detriment to others. It is necessary, therefore, to establish a rotation of cultures and herbicids in order to control the most damaging species in an effective way. KEY-WORDS: Agro-ecosystems; weeds. |

No município de Edéia (GO), muitos dos produtores que aderiram ao sistema de plantio direto se queixaram dos elevados gastos com o controle de plantas daninhas. Diante deste problema, este estudo procurou quantificar a emergência de plântulas no início da estação chuvosa, comparando agroecossistemas em várias propriedades do município de Edéia. Foram escolhidos quatro agroecossistemas: 1) Soja/Milho/Soja/Sorgo/Soja (área I); 2) Soja/ Milho/Soja/Sorgo/Soja (área II); 3) Milho/Soja/Sorgo/Soja; 4) Soja/Soja/Milho/Braquiária. Os resultados foram expressos em população de plantas daninhas por m². Para análise estatística foram formados os seguintes grupos: a) principais espécies dicotiledôneas; b) principais espécies monocotiledôneas; c) espécies de culturas de safrinhas; d) espécies de braquiárias. Concluiu-se que o manejo adotado pelos produtores nas safras dos dois últimos anos privilegiou certas espécies em relação a outras, devendo, portanto, promover rotação de culturas e herbicidas para que se possa, assim, controlar eficientemente as espécies mais problemáticas.
