A study was undertaken to find out influence of storage on physical properties of stored paddy in different types of storage structures. The experiment included six different types of low cost structures developed utilizing locally available materials. The study indicated that the moisture content of paddy decreased initially up to 150 days of storage, beyond which it increased due to increase in relative humidity of the atmosphere. The temperature of stored paddy increased initially up to 120 days and thereafter decreased. The germination and seed viability of stored paddy were found to be affected. The highest germination loss of 78.5% was recorded in bamboo storage structure lined with polyethylene in the inner surface and painted black on the outer surface whereas the lowest germination loss was recorded in bamboo storage structure plastered with cement in the inner and outer surfaces. Appreciable damage of stored paddy due to insects was also observed over a period of seven months.
