Abstract

The present work aims at the study on the impact
of seasonal variation on physico-chemical properties
and vertical distribution of soil mycoflora of grassland
ecosystem in different seasons from the depths of 0-5,
5-10, 10-15 cm. During the study, the effect of seasonal
fluctuation was observed on the various parameters of
the soil and vertical distribution of fungal population.
The results revealed that the soil texture was sandy having
sand 38.2%, silt 33.0% and clay 28.8%. Range of
values of other parameters recorded were temperature
(27 – 410C), pH (7.02 – 8.89), moisture content (7.95 –
24.32%), organic carbon (0.51 – 0.74%), organic matter
(0.93 – 1.28%), nitrogen (1.29 – 1.70%) and phosphate
(1.113 – 0.178%). The distribution of soil microfungi
decreased with the increase in soil depth. In general,
the number of fungal species was highest during rainy
season. About 24 different fungal species were isolated
at different depths in three different seasons, among
them Fusarium udum, Curvularia lunata, Penicillium
citrinum, Rhizopus nigricans, Trichoderma lignorum
and Trichoderma viride were common at all depths in
all the seasons. Seasonal variation in physico-chemical
soil parameters played a significant role in the occurrence,
diversity, distribution and relative abundance of
fungal species in the investigated soil samples.
