A study was conducted for the isolation and identification of soil fungi associated with cotton and cucumber plants cultivated in Koppal region of Karnataka. Soil samples were collected from cotton and cucumber plants growing fields during the months of January 2018 to November 2020, at Koppal region of Karnataka, India. Soil fungi were isolated by using soil dilution technique on PDA medium containing strepto - penicillin. Identification of the soil fungal isolates was made with the help of relevant literature and standard manuals of soil fungi. The number of fungal isolates present in cotton plants field is 51,550 per gram of soil. The number of fungal isolates present in cucumber plants field is 8, 21,800 per gram of soil. In cotton plants field, the percentage contribution of Basidiomycotina is more with 18.60%, In cucumber plants field, the highest percentage contribution is given by Aspergillus niger with 27.5%, In cotton plants field, 14 different species belonging to 9 genera. Among which Aspergillus species is dominating over other species. In cucumber plants field, 9 different species belonging to 5 genera were observed. Among which Fusarium sp. is dominating over other species. The most frequently isolated fungi from the cotton plants and cucumber plants fields of Koppal region is Aspergillus sp and Fusarium sp. In cotton plants field, amongst the isolates, 6 Aspergillus species (A. niger, A. flavus, A. fumigatus, A. awamori, A. terreus, Aspergillus sp.) 2 Fusarium species (Fusarium oxysporum F. pallidoroseum) and in cucumber plants fields among the isolates 3 Aspergillus species (A. niger, A. flavus, A. awamori,) 3 Fusarium species (F. oxysporum F. pallidoroseum, Fusarium sp.) were characterized and percentage occurrence of the soil fungi was statistically evaluated.
