Effect of Storage Duration and Storage Devices on Seed Qualityo f Boro Rice Variety BRRI dhan47

Abstract

An experiment was conducted to evaluate the effect of storage device and storage duration on seed germination and seedling growth parameters of Boro rice variety BRRI dhan47. The experiment was laid out in a completely randomized design (CRD) with two factors and three replications. The storage devices used in this study were gunny bag, earthen container, tin container and plastic container. The storage durations were 2 months, 4 months and 6 months. Germination test was done in the laboratory following rolled paper method. Data were collected on moisture percentage, insect population, germination percentage, and root and shoot length, root dry mass and shoot dry mass. Seed germination and seedling parameters showed wide variations due to different storage devices and storage duration. Germination parameters were negatively affected by increasing storage duration. The number of insect population were increased; while the germination percentage, root length, shoot length, root dry mass and shoot dry mass decreased in the seeds stored into different storage devices and with increasing storage duration. All the seedling parameters were found zero for the seeds stored in all the four containers after 6 months of storage with few exceptions in gunny bag. Seeds stored in porous containers gave better performance than the seeds stored in airtight containers.
