Weed detection of irrigated barley fields can be considered as the most important strategy for weed management of in this crop. Based on cropping area of barley and frequency of fields in each county of Kermanshah province, barley fields were selected. In order to identify and determine the abundance of weed species in irrigated barley fields of Kermanshah province, Iran, 142 barley fields in eight counties during 2001 to 2009 were investigated. Samplings were conducted using a unique method for all fields. Geographic coordinates of fields (latitude, longitude and elevation) were determined using GPS. Density, frequency and uniformity of each weed species was calculated. A geodatabase was designed using ArcGIS software, and finally the weed map of irrigated barley fields were produced. There are 53 weed species in irrigated barley fields. Bedstraw(Galium tricornutum Dandy.), Centaurea depressa and Vicia villosa are the most important broad leaved weed species respectively and Wild barley (Hordeum spontaneum C. Koch.) and winter wild oat (Avena ludoviciana Dur.), are the most important grass weed species respectively in irrigated barley fields.Licorice root (Glycyrrhiza glabra), Sophora alopecuroides and Cirsium arvense were the most widely disturbing plants in barley fields of Kermanshah province prior to harvesting respectively. Analysis of weed population based on Shannon-Wiener diversity index showed that the counties were grouped in three clusters. Javanroud, Songhor, Sahne, Kangavar, Harsin and Kermanshah were placed in first cluster and showed the highest species diversity. Sarpole zohab and Eslamabade gharb counties were placed in the second and third cluster respectively.
