The relationship of moisture content and storage period with fungal population, and seed germination was studied. Various fungal species predominated at different moisture conditions and storage periods. The fungi observed are given. A decrease in the number of field fungi and an increase in the number of storage fungi with storage time were observed. Storage fungi from the wet and dry season samples were noted as early as five weeks after storage at moisture contents of 9.3 - 18.33%. The percentage germination of paddy remained higher when stored at moisture contents of 9.3-14.0% but decreased with storage time at 4.5-18.3% moisture content. The percent germination of paddy reached a peak at 10-15 weeks of storage and gradually decreased during further storage. A significant negative correlation between percent germination and moisture content was observed.
