摘要：

Combinations of rotary hoeing, cultivation, and band- or broadcast-applied herbicides were compared for weed management in corn at 64 locations in Iowa from 1987 to 1991. Cultivation alone resulted in denser weed populations than herbicide treatments at 41% of the locations; however, corn yields were reduced at only 22% of the locations when weeds were controlled mechanically rather than with herbicides. Compared with broadcast applications, herbicides applied in a band resulted in increased weed populations at 8% of the locations; however, corn yields were reduced at only 1% of the locations.
