The purpose of this study was to examine the effects of black polyethylene film mulching and soil conditioners on the growth, yield, and flavonoids biosynthesis of mungbeans. The seedling stand rate, plant height, and pods per plant were 98%, 61 cm, and 15.1, respectively, when the mungbean grown black polyethylene film mulches. They were greater than these results when the without mulches was applied by 13%, 9 cm, and 1.8, respectively. Mungbean grown with black polyethylene film mulches (243 kgㆍ10a-¹) exhibited 38% more seed yield than without mulches (176 kgㆍ10a-¹). However, no significant difference in contents of vitexin and isovitexin of mungbeans between with black polyethylene film mulches and without mulches was observed. Among soil conditioners, standard fertilizer+oil cake and standard fertilizer+mineral powders increased number of pods. The standard fertilizer+oil cake showed the highest seed yield (119%) of mungbean when it mixed with standard fertilizers, and followed by mineral powders (115%). The mixed combinations of oil cake or mineral powders also seem to have affected the biosynthesis of vitexin and isovitexin, whose content in mungbeans was significantly more.
