A germination test was carried out to observe the germinability of mungbean seed under storage periods and storage containers at Agronomy laboratory of Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur, Bangladesh during April-May 2014. The experiment was designed completely randomized design (CRD) with eight replications under three storage periods (15, 30 and 45 days after storage (DAS)) and three seed containers (tin container, polythene bag and gunny bag). The maximum values of germination percentages (GP) were recorded of mungbean seed with 15 days after storage (DAS) and the GP reduced significantly with increasing storage periods from 15 to 30 and 45 DAS. The highest GP (82.00%) was found at 15 DAS in tin container while the lowest (51.01%) at 45 DAS in gunny bag. The rate of reduction was found to increase with the advancement of storage periods. The germinability of mungbean seed was observed maximum levels (82.00, 80.89 and 72.68%) when seeds stored in tin container, and the minimum levels (72.42, 66.11 and 51.01%) whilst the seeds stored in gunny bags among the three storage containers under all storage conditions. Mungbean seed kept in gunny bag and tin container provide the highest and lowest reduction of GP, respectively. An excellent performance of germination was observed in tin containers seed while the gunny bag provided the inferior seed germination among all of the three containers. Finally, it could be possible to enhance and maintain the quality of mungbean seeds through proper storage medium with the adequate periods.
