High quality seeds of sweet corn will lead to high productivity. The quality of seeds can be known through germination testing. The field emergence test is one of seed quality testing with approach to a new method of quality testing in the field. The aims to study seed testing with the approach of field emergence method and finds out its relationship with the germination and vigor tests. This research used randomized complete block design (RCBD) with seven replications on each variety. Field emergence test was carried out by observing the number of open leaves and plant height while laboratory seed quality tests were assessed using standard germination test and accelerated ageing (AA) vigor test. The result showed that the field emergence test observed at 14 days after planting (DAP) gave a clear distinction of normal and abnormal plants, with a criteria normal plant had a criterion 3-4 open leaves and 16.9 ± 2.9 cm in plant height while abnormal had less than 3 leaves and short plant height. Field emergence percentage was calculated by the number of normal plants. There was a correlation at each time of observation of field emergence with germination and vigor tests result.

Mung bean seeds (Vigna radiata) are categorized in orthodox seed group that need specific storage room condition and appropriate package in order to maintain their quality and for longer storage. This research aimed to study the effects of storage package types, storage room conditions, and storage periods on the shelf life of mung bean seeds. This research used Completely Randomized Design (CRD) with 3 factors, namely the type of packages (aluminium foil and can), storage room conditions (room temperature and AC temperature), and storage periods (0, 3, 6, 9, and 12 months). The results showed that a single factor, the interaction of two factors, and interaction of three factors namely, storage packages, room conditions, and storage periods had no significant effect in terms of seed moisture content (SMC), growth rate (GR), and maximum potential growth (MPG). It indicated ability of both aluminum foil and can packages in limiting the air (oxygen) and water movement between the outside atmosphere and the stored seeds inside the package during storage. According to the study, aluminum foil and can packages can be used to maintain the quality of VIMA 1 mung bean seeds for 12 months storage at room and AC temperature.
