Resumo: | Researches of many South American countries point the zero tillage system of crop production for little farmers as a responsible factor for best soil and water conservation, less costs of production and best profits to improve the rural way of life. The treatments usually include the application of herbicides. To find agricultural systems that allow zero tillage without herbicide or with reduced usage has been considered a challenge by the researchers. This experiment was carried out in order to evaluate the effects of different mulches on the control of unwished plants in maize crop (Zea mays). Plants such as sunhemp (Crotalaria juncea), millet (Pennisetum americanum) and sunflower (Helianthus annus L.) cv. Stanzuela and V 2000 were grown in 100 m² areas. The sowing was made at the second April fortnight and, after sixty days, the zero tillage system with maize was established by using a manual planting machine. Just after, the plants grown in the plots were manually cut and used as mulch. The soil fertility was corrected according to the laboratorial analyses and the plant population adopted was around 60,000 plants per hectare. No weed control was made. At the maize flowering, the seed weeds grown in the plots were collected by using two samples of 1 m² plot (two replications). The plant material was dried till constant weight. Statistical analyses obtained from the data indicated the millet mulch as the best treatment to the weed control. KEY-WORDS: Mulches; uwished plants; maize crop. |

Pesquisas em diversos países sul-americanos apontam o plantio direto para pequenos produtores como responsável por melhor conservação do solo e água, menores custos de produção e maiores rendimentos, melhorando o nível de vida dos produtores e propiciando sua permanência no meio rural. Os tratamentos normalmente incluem a aplicação de herbicidas e considera-se um desafio à pesquisa encontrar sistemas que viabilizem o plantio direto sem uso, ou com uso reduzido, de herbicidas. Objetivando avaliar os efeitos de diferentes coberturas mortas sobre o controle de plantas indesejáveis na cultura do milho (Zea mays), conduziu-se o presente trabalho, cujos tratamentos foram constituídos pelo cultivo de áreas de cem metros quadrados com as seguintes plantas: crotalária (Crotalaria juncea), milheto (Pennisetum americanum) e girassol (Helianthus annus L.), cultivares Stanzuela e V 2000. A semeadura foi efetuada na segunda quinzena do mês de abril e, decorridos sessenta dias, foi feito o plantio direto do milho, com matraca. Imediatamente após, as plantas constantes nas parcelas foram cortadas manualmente, constituindo-se em cobertura morta. Fez-se adubação de acordo com a análise do solo e a população adotada foi de 60.000 plantas por hectare. Não houve controle de plantas daninhas. Por ocasião do florescimento do milho, coletaram-se as plantas daninhas presentes nas parcelas, mediante amostragens de 1 m² (duas repetições). O material foi seco até peso constante. A análise estatística dos dados obtidos indicou a cobertura morta proporcionada pelo milheto como o tratamento que melhor controlou a presença de plantas indesejáveis.
