With increasing cropping acreage, unit area production and total yield since 1945, corn (Zea maysL.) becomes the major dryland crop grown in Taiwan recently. During its growth, yet, the occurrence of weeds can cause losses by reducing yield, by lowering quality, and by hindering harvest. In 1993 ¡¥ nearly 1.4 billions of New Taiwan dollars were estimated spent for controlling weeds in this crop. It is therefore a need to conduct research on the extent and causes of the losses through weed interference. Additionally it is a primary concern of corn producers in Taiwan to reduce the production costs nowadays. No-till cultivation is one of the solutions that has actually being taken for this purpose. However, the interference of the naturally occurring weed infestations on the process of corn growth should be fully understood before such practice be extensively esteemed. The objectives of this paper are to discuss the effects of weed interference on the growth and yield of no-till corn, and to describe in details the relationships between yield and the duration of weed interference and the amount of weeds occupied in the field.
