Totally 3 different irrigated paddy field soils were collected from Thanjavur district, Tamilnadu and their physico-chemical properties and population density of mycoflora were analyzed. Among them, 2 samples were sandy clay loamy soil and 1 sample was loamy soil. The physiochemical parameters were also analysed. The population density of mycoflora was maximum (52) observed in sandy clay loamy soil at Kollakadu, minimum (33) population density was observed in loamy soil at Pathirankottai. Totally 22 fungal species belongs to 2 genera Aspergillus and Penicillium sp were isolated from the three different samples. | Studies on mycoflora population in various irrigated paddy field soil at Thanjavur district India
