Resumo: | The emerging flora of seedlings and weeds in several soil cover systems was studied through: a) cover crops under no-tillage (pigpeas; brachiaria; pearl millet; gray mucuna; oats; striped mucuna; saracen wheat; crotalaria) and b) tillage systems (minimum tillage; cover removal; no-tillage on grown weeds; conventional tillage). Evaluation of the emerging flora showed that among cover crops the treatments with pearl millet and the brachiaria presented low monocotyledonous incidence (0.66 pl/m²), differing however from the conventional tillage (50.33 pl/m²). The dicotyledonous occurrence was inhibited by crotalaria presence, saracen wheat and pearl mullet (1.00, 1.00, and 1.33pl/m², respectively), only oats differing within cover crops (18.66 pl/m²). The residual population of pearl millet (130.66 pl/m²) was statistically higher than residues of brachiaria, gray mucuna, and striped mucuna (1.00, 0.00, and 0.33 pl/m², respectively). It was found that the complete soil cover was achieved with brachiaria, which controlled weeds efficiently. Pearl millet and crotalaria showed good mono- and dicotyledonous control, achieving good soil cover. However, the emergence of volunteer pearl millet may pose management problems for the subsequent crop. KEY-WORDS: Crop systems; weeds; flora. |

O objetivo deste trabalho foi determinar a flora emergente de plântulas e plantas daninhas em vários sistemas de cobertura do solo e manejo com: a) culturas de cobertura em plantio direto (feijão-de-porco; braquiária; milheto; mucuna cinza; aveia; mucuna rajada; trigo sarraceno; crotalária) e b) sistemas de cultivo (cultivo mínimo; retirada da cobertura; plantio direto no mato; plantio convencional). A avaliação da flora emergente demonstrou que, dentre as culturas de cobertura, os tratamentos com milheto e braquiária apresentaram baixa incidência de monocotiledôneas (0,66 pl/m²), diferenciando-se, entretanto, apenas do plantio convencional (50,33 pl/m²). A ocorrência de dicotiledôneas foi inibida quando em presença de crotalária, trigo sarraceno e milheto (1,00; 1,00; 1,33 pl/m², respectivamente), que se diferenciaram dentre as culturas de cobertura, apenas da aveia (18,66 pl/m²). Houve uma elevada população de plantas residuais de milheto (130,66 pl/m²), estatisticamente superior ao residual das culturas de braquiária, mucuna cinza, mucuna rajada (1,00; 0,00; 0,33 pl/m², respectivamente). Concluiu-se que a cobertura total do solo foi a proporcionada pela braquiária, com eficiente controle de plantas daninhas. O milheto e a crotalária controlaram muito bem as espécies mono e dicotiledôneas, estabelecendo uma boa cobertura do solo. Contudo, a emergência de plântulas de milheto, após o cultivo desta cultura, pode dificultar o manejo para implantação da cultura subseqüente.
