摘要：

The effect of summer and winter annual scentless chamomile (Matricaria perforata Merat) on the grain yield of winter wheat was investigated for 3 vr in experimental plots. Summer annuals only affected yield in a year with much greater than normal precipitation. Under near-normal weather conditions, winter annuals reduced yield. Yield reductions due to interference from either summer annual or winter annual scentless chamomile were not detected in a year marked by hot and dry conditions.
