Abstract: 

IN ORDER TO IDENTIFY WEEDS INTERFERING IN SUGAR BEET CROPPING SYSTEMS OF SHAHROOD AND INVESTIGATING THEIR VARIATION, THE PRESENT STUDY WAS CONDUCTED DURING 2008. FIELDS WERE CLASSIFIED INTO FOUR MAJOR GROUPS BASED ON THEIR FREQUENCY AND AREA UNDER CULTIVATION. SAMPLING WAS CONDUCTED USING 1MX1M QUADRATES ADOPTING W PATTERN. WEEDS COUNTED SPECIES WISE TO CALCULATED ECOLOGICAL INDICES LIKE FREQUENCY AND VARIATION. SHANNON AND SIMPSON INDEX WERE CALCULATED. THE RESULTS SHOWED THAT THIRTY SIX WEED SPECIES WERE PRESENT IN THESE FIELDS. SIGNIFICANT DIFFERENCES WERE OBSERVED BETWEEN SUMMER AND SPRING DOMINANT SPECIES.
