Moisture Content and Germination of Bean (Phaseolus vulgaris L.) Under Different Storage Conditions

A laboratory experiment was conducted with bean seeds kept in three different containers viz. tin pot, poly bag and jute bag and stored at room temperature and RH for three months in the Laboratory of Agronomy Department, Sher-eBangla Agricultural University to study their storage behavior, germination percentage and quality. The seed of jute bag came to the contact with air and their moisture contents was increased from initial moisture content and remained near to their Equilibrium Moisture content (EMC), moisture content of the seeds of jute bag was found increased from 8.7% to 16.7% within 69 days of storage. But increase of moisture contents of seeds of tin pot and poly bag was lower as compared to jute bag. As tin pot and poly bag was more or less air tight so the seeds of these container could not come to the contact with ambient room air, resulting less change of their moisture content as compared to gunny or jute bag. Germination capacity of the seeds of tin pot was found decreased from 90% to 70.3% and 90% to 67.5% in the seeds of poly bag. Germination percentage of the seeds of jute bag was found decreased from 90 to 62% in 69 days of storage. So, the germination capacity was also found a little bit higher in tin than the seeds of other containers. Considering three different containers, tin container has been proved much more safe and secured than jute or poly bag container.
