Abstract :

Geographic information system (GIS) as a powerful tool can provide comprehensive information to weed researchers. Based on cultivation area in most cities of Markazi province during 5 years (2000-2004) , 70 samples of dryland wheat fields were selected and weed species were counted in each sampling point and population indices were calculated. In each field longitude, latitude and altitude were recorded using GPS. These data were used for producing weed maps using GIS. Results showed that dominate broadleaf species were spurge (Euphorbia sp.), salsify (Tragopogon graminifolius DC.) , madwort (Alyssum marginatum Steud. ex Boiss), Goldbachia laevigata (M.B.)DC., and dominante grass weed species were downy brome (Bromus tectorum L.), squarosa couchgrass (Eremopyrum bonaepartis (Spreng)Nevski), common rye (Secale cereal L.), in dryland wheat fields.
