Abstract :The microfungal flora of field soils irrigated by the South-eastern Anatolia Project insert ignore into journalissuearticles values(GAP: Güneydoğu Anadolu Projesi); in Harran Plain were investigated in terms of quality and quantity, using the soil dilution plate and soil washing methods. A total of 1690 microfungi were isolated from 105 soil samples. With the identification of these isolates, 109 species plus 16 different sterile fungi were identified. Sixty-two of these taxa were isolated through the soil dilution plate method, seven through the soil washing method, and 40 through both methods. The results indicate that ten of these species belong to Mucorales, four to Sphaeriales, one to Coelomycetes and 94 to Hyphomycetes. The most widespread genera were Penicillium Link ex Gray insert ignore into journalissuearticles values(24 species);, Aspergillus Mich. ex Fr. insert ignore into journalissuearticles values(20 species);, and Acremonium Link ex Fr. with the soil dilution plate method. The most common species were Aspergillus niger Tiegh. insert ignore into journalissuearticles values(284 colonies);, Penicillium lanosum Westling insert ignore into journalissuearticles values(238 colonies);, Penicillium canescens Sopp. insert ignore into journalissuearticles values(170 colonies);, Penicillium brevicompactum Dierckx insert ignore into journalissuearticles values(174 colonies); and Penicillium clavigerum Demelius insert ignore into journalissuearticles values(146 colonies);. The results obtained from the soil dilution plate method show that fresh soil bulk equivalent to 1 g of oven-dried soil contains on average 72 487 propagules.
