Diversity of Rhizosphere Fungi and Soil Nutrient Properties of Amorphophallus sylvaticus (Roxb.) Kunth

In present investigation diversity of rhizosphere fungi of Amorphophallus sylvaticus (Roxb. ) kunth a monsoon perennial cormatus plant species belonging to family Araceae was studied from two sites of Nanded district by using serial dilution and soil plate methods on the Czapeks Dox Agar and MRBS Agar medium. Soil chemical properties, including pH, electrical conductivity, organic carbon, P, K, Cu, Fe, Mn, and Zn content, were also analyzed. The soil nutrition status shows low content of macronutrient and it may be negatively influence on rhizosphere fungal diversity of plant. Quantitative analysis of fungal population of Pota site is greater than Nageli site. A total 21 fungal species from rhizosphere of Pota site and 16 species from Nageli site were isolated and identified. The rhizosphere fungal population of each site was correlated with the soil chemical properties of each site and there is a significant correlation between fungal populations with the chemical properties investigated. The most dominant species includes Aspergillus flavus, Aspergillus niger, Penicillium chrysogenum, Penicillium citrinum, Rhizopus stolonifer, Rhizoctonia sp. , Fusarium oxysporum, Trichoderma harzianum & Alternaria alternata.
