Abstract: 

APPROPRIATE CROP ROTATION SYSTEM IS AN OUTSTANDING AGRONOMICAL MEANS OF WEED MANAGEMENT. IN ORDER TO ASSESS THE REACTION OF WEEDS TO A NUMBER OF DIFFERENT ROTATIONS, A SIX-YEAR EXPERIMENT WAS CONDUCTED BASED ON A RANDOMIZED COMPLETE BLOCK DESIGN WITH FOUR REPLICATIONS AT AGRICULTURAL RESEARCH STATION OF KHORASAN RAZAVI, LOCATED IN JOLGEH ROKH. EXPERIMENTAL TREATMENTS INCLUDED: VETCH-POTATO, CANOLA-POTATO, BARLEY-POTATO AND FALLOW-POTATO (CONTROL). EACH ROTATION WAS REPEATED THREE TIMES DURING THE 6-YEAR COURSE OF THE EXPERIMENT. THE RESULTS INDICATED THAT CANOLA-POTATO ROTATION PROVED HIGHLY SUCCESSFUL IN CONTROLLING WEEDS DURING THE GROWING SEASON, INTERESTINGLY ENOUGH, UNLIKE OTHER ROTATIONS; IN CANOLA-POTATO ROTATION DID NOT SUFFER FROM BINDWEED UNLIKE OTHER ROTATION SYSTEMS. THE HIGHEST DENSITY OF PERENNIAL WEEDS WAS OBSERVED IN THE FALLOW-POTATO ROTATION. THE BARLEY-POTATO ROTATION MADE AN APPROPRIATE CONTROL OF THE WEEDS. THE MAJORITY OF WEEDS OBSERVED IN SAMPLING WERE SPRING ANNUAL ONES, WITH LAMBS QUARTER AND PIGWEED BEING THE DOMINANT SPECIES. IN CONCLUSION, IT CAN BE SUGGESTED THAT IDENTIFICATION OF THE MOST SUITABLE ROTATION FOR EACH SPECIFIC REGION CAN BE APPLIED AS A MEANS TO SUSTAINABLE WEED CONTROL.
