Seed Quality of Aman Rice as Affected by Some Alternate Storage Devices

3 Abstract: The study was carried out to evaluate the efficiency of storage devices on seed quality of Aman rice. USA organic cocoon, Germax cocoon, IRRI made storage bag, rexin cocoon and thick poly bag maintained lower moisture content below the critical level (14%) compared to polythene and gunny bag. USA organic cocoon, IRRI made storage bag and Germax cocoon were able to reduce oxygen level significantly (3.7, 7 and 12.23%) and killed more than 90% insects of the stored seeds compared to polythene type of bags, rexin cocoon and gunny bag. Highest 1000-seed weight was observed in seeds of gunny bag (26 g) and the lowest range (23.4-23.6 g) was in USA organic cocoon, Germax cocoon and IRRI made bag due to higher moisture content (15.27%) in gunny bag and lower moisture content (<12%) in latter devices. USA organic cocoon, Germax cocoon and IRRI made bag maintained an excellent germination rate (>90%) when Aman seeds were stored in this devices. Seed vigour, shoot and root growth were significantly affected when Aman seeds were stored in polythene type of bags and rexin cocoon though these devices were able to maintain a fai r germination range of 82-87%.
