%X This study was conducted to determine weed species, their distributions and densities in wheat growing areas of A£¿r£¿ province and its districts during wheat groving seasons of 2013 and 2014. For this aim surveys were done according to wheat production areas of A£¿r£¿ province and their districts Diyadin, Do£¿ubayaz£¿t, Ele£¿kirt, Hamur, Patnos, Ta£¿l£¿£¿ay and Tutak during June and July. To determine weed species in wheat fields surveys were conducted on the way of wheat production areas. Survey fields were chosen randomly by stopping at every 10 km. On each field, four 1 m2 quadrants were placed randomly, weed species inside the quadrants were counted and their percentage coverage areas were identified. The surveys resulted with 96 weed species belonging to 22 families in wheat fields. According to the weed species included, top 3 largest families were found to be Asteraceae (17), Poaceae (14) and Amaranthaceae (10) in 2013. In 2014 the surveys resulted with 99 weed species belonging to 22 families in wheat fields. According to the weed species included, top 3 largest families were found to be also Asteraceae (18), Poaceae (13) and Amaranthaceae (10). According to the both years result,a total of 103 different weed species belonging to 22 similar families were detected. And of all these species, 50 species were displayed a frequency of more than 10 percent totaly. Top 10 species were found as Avena fatua L., Cirsium arvense (L.) Scop., Convolvulus arvensis L., Sinapis arvensis L., Convolvulus galaticus Roston. Ex Choisy, Secale cereale L., Rumex crispus L., Lolium perenne L., Capsella bursa-pastoris (L.)
