Abstract:

This study was carried out in the form of survive studies in the Siirt or Antep bean gardens with the aim of determining foreign herbs and their prevalence and intensity and covering areas; in the period of vegetation 2017-2018. In the framework of the study, a total of 103 beef gardens randomly selected to represent the region have been observed. As a result of the surveillance studies, a total of 170 foreign grass species of 37 families, including 4 single and 33 double grass species, were identified. The families with the most taxon in terms of the number of foreign herbs are Asteraceae (29 species), Poaceae (23 species), Fabaceae (18 species), Apiaceae (12 species) and Brassicaceae (12 species). The highest frequency of appearance among the specified species is the foreign herbs, Avena spp. It was found to be Anchusa azurea Miller., Bromus tectorum L., Cardaria draba (L.) Desv., Carduus pycnocephalus L., Fumaria officinalis L., Lamium amplexicaule L., Lactuca serriola L., Galium aparine L., Lolium perene L., Medicago sativa L., Papaver rhoeas L., Sinapis arvensis L., Thlaspi arvense L. and Vicia sativa L. The largest species in the region is Cynodon dactylon (L.) Pers. It is known as Convolvulus arvensis. The total coverage area of foreign herbs in the Antep bean gardens is estimated at approximately 37%. The number of foreign herb species, the frequency and intensity of species and the direction of covering areas have been found to have great differences between the districts. The general coverage area of foreign herbs was at the highest level (53%) in the Central District, while the lowest level (19%) in the Baykan District. In addition, in the Eruh (155 species) district the largest number of foreign grass species is found, while the least number of species is found in the Baykan (76 species) district. The results showed that foreign grass management strategies specific to the region should be implemented in the field of study.
