Abstract: 

IN ORDER TO INVESTIGATE THE EFFECTS OF VARIOUS CORN (ZEA MAYS L.) AND BEAN (PHASEOLUS VULGARIS L.) INTERCROPPING DENSITIES ON WEED POPULATIONS, AN EXPERIMENT WAS CONDUCTED BASED ON RANDOMIZED COMPLETE BLOCK DESIGN WITH THREE REPLICATIONS DURING 2008 GROWING SEASON AT AGRICULTURAL RESEARCH STATION OF FERDOWSI UNIVERSITY OF MASHHAD. TREATMENTS INCLUDED: INTERCROPPING OF BEAN WITH CORN AT THE NORMAL DENSITY OF BEAN PLUS 10%, 20% AND 30%, INCREASE IN CORN DENSITY, INTERCROPPING OF BEAN WITH CORN AT THE NORMAL DENSITY OF CORN PLUS 10%, 20% AND 30% INCREASE IN BEAN DENSITY, AND SOLE CROPS OF CORN AND BEAN. WEED SAMPLINGS WERE DONE IN THREE STAGES, THAT INCLUDING EARLY, MID AND LATE OF GROWING SEASON. THEN, WEEDS WERE COUNTED AND MEASURED THEIR DRY MATTER. THE RESULTS INDICATED THAT THE EFFECT OF VARIOUS CORN AND BEAN INTERCROPPING TREATMENTS ON DRY WEIGHT OF BROAD AND NARROW LEAF WEEDS WERE SIGNIFICANT (P£0.01). WITH INCREASING OF PLANT DENSITY, DRY WEIGHT OF WEEDS WAS DECREASED. THE HIGHEST AND LOWEST AMOUNTS OF RELATIVE FREQUENCY OF DOMINANT WEED SPECIES WERE OBTAINED FOR NUTSEDGE (CYPERUS ROTUNDUC) AND BIND WEED (CONVOLVULUS ARVENSIS) WITH 21.91-45.65% AND 0.85-16.22%, RESPECTIVELY.
