Mycoflora of soils, separately amended with urea, ammonium sulphate, superphosphate, organic manure and fresh leaves/twigs of Ipomoea fistulosa and regularly irrigated, has been investigated. Each amendments was applied at 60 kg/acre. 52 fungal species, comprising 7 spp. of Phycomycetes, 1 Ascomycetes, 38 spp. of Deuteromycetes and 7 sterile colonies, were isolated from the amended and control plots. Fungal population was higher in the amended soils as compared to control. Organic manure and irrigated plots, however, possessed more fungal populations. Among the fertilized plots, the ones amended by urea gave the highest yield, followed by those amended by superphosphate and ammonium sulphate in the decreasing order. During early stages, the plots supplemented with I. fistulosa gave considerably low fungi, with the population, however, increasing at the later stages. The increased nutrition status by various amendments has been emphasized for the increased mycoflora in the amended plots. (Full paper at Slideshare.net)
