Determining some of the fast-growing broadleaved species that can be used in afforestation along irrigation channels (？anl？urfa-Harran sample)

This study was carried out in the GAP region near Ak？ren village of ？anl？urfa-Harran plain. The research study aimed to identify some of the fast-growing broadleaved species that could be grown in buffer areas between agricultural areas and irrigation or drainage channels that are common in the region. In the experiment, Kocabey clone (77/10), Anadolu (TR-56/75) and 92.126 clones of black poplar (Populus nigra), 62.012 (Salix alba) and 84/3 (S. alba) and NZ.1001 (S. matsudana x S. alba) hybrid clone of salix species, Australian origin of Eucalyptus camaldulensis no.7046, euphrates poplar (Populus eupratica Oliv.) of Birecik/？anl？urfa origin and white poplar (P. alba) of Tunceli origin were used. The seedlings were planted in two rows and crosswise in the experimental design. In the 5th year in the experiment, the diameter, height, insect damage and survival percentages were evaluated. According to this, especially the origin of the eucalyptus no. 7046, Kocabey clone of black poplar and Birecik/？anl？urfa origin of the euphrates poplar were found to be successful. Among these species, the Euphrates poplar which was used for the first time in the afforestation activity in the Southeastern Anatolia region showed a better performance than the other species and origins regarding survival percentage (100%) as well as good diameter and height development. In Harran/？anl？urfa region, these 3 species can be used in afforestation activities in areas where irrigation may be possible, especially considering the frost hazard that can be seen in the first years of eucalyptus. Eucalyptus species can be used near the irrigation and similar drainage channels or roadsides with water, starting from the southern part of Viran？ehir, Ak？akale, Ceylanp？nar, and Harran located in the south of ？anl？urfa province where frost damage is seen less frequently and less severely. Depending on the width of the area and conditions of the region, the plantings can be applied in 1 to 3 rows or as a gallery
