- Abstract
Fungistasis property of soil samples from forest area, cultivated field, and grassland field has been studied. Soil samples from different depths were collected in summer, rainy, and winter seasons. The effect of amendment of certain fungal isolates, culture filtrate, mycelial extract and certain plant materials in sterilized soil has also been studied. Generally the fungistasis property was found to be higher in soil samples of upper profiles and it gradually decreased with an increase in soil depth in all the three localities. Highest fungistasis was observed during rainy season when fungal population was also found to be higher. Amongst three localities, higher values were always noticed in forest soil samples. Physico-chemical characters seem to play an indirect role in inducing the soil fungistasis. Fungal spores, culture filtrates and mycelial extracts of certain fungi caused different levels of fungistasis in sterilized soil. Sterilized soil samples amended with various plant parts also caused fungistasis after certain period. Thus fungistasis seems to be a combined effect of various factors existing in the soil.
