The purpose of this study was to determine the effect of seed size on the speed of emergence in the field conditions, which included the efficiency of germination and sprout production in laboratory test. The experiment was conducted in a split-plot design using varieties/lines as the main plot and seed size as the sub-plot. The results showed no effect of seed sizes on speed of emergence in field setting both in rainy and dry season. Nevertheless, the speed of emergence in rainy season was higher than that of the dry season. Correlation among agronomic characters revealed that seed size was the character which may compensate to the other yield components. The result of the field testings both in rainy and in dry seasons was similar. The experiments also showed that large seeds had higher germination percentage than that of small seeds. In general, mungbean sprouts from large seeds were heavier and had bigger head and stem but was shorter than the sprouts from small seeds. Therefore, the results from this study suggested that the large seeds would be advantageous only for sprout production but small seeds are also suitable for planting without any effect on early stage of plant growth such as speed of emergence.
