Abstract
O controle de ervas daninhas em cafezal cultivado em latossolo roxo, por meio de métodos mecânicos (grade de discos, enxada rotativa, roçadeira) e químico (herbicida), é comparado com a capina manual. Cada implemento foi sistematicamente usado durante o período das águas. Quanto à produção, após dez anos, não houve diferença estatística entre os tratamentos, a não ser no biênio 1976/77, quando a grade e a enxada rotativa tiveram melhor comportamento, não diferindo do herbicida. Observaram-se sinais de erosão superficial provocada por grade de discos, enxada rotativa e herbicida.
Mechanical (disc harrow, rotary cultivator, off-set rotary shredder), chemical (herbicide) and hand hoe weeding are compared in a coffee crop grown on a latosol. After ten years there was no significant yield difference among the treatments. There was however, visible signs of erosion due to the use of disc-harrow, rotary cultivator, and herbicide.
