Abstract
This study characterized the emergence pattern of a weed community of 16 species between April 1 and August 31 over a 7-yr period. Weed seedlings were counted weekly in quadrats established in winter wheat stubble within no-till and conventional-till production systems. Weed emergence showed two peaks, the first between April 25 and May 9, and the second between May 30 and June 13. Tillage did not affect the weed community emergence pattern. Knowledge of weed community emergence pattern in conjunction with crop simulation models could be used to suggest cultural practices such as optimal planting dates that favor a crop over weeds, and possibly reduce herbicide use for within-crop weed control.
