摘要

Common bean is a susceptible vegetable to excessive water condition in soil. Meanwhile, flooding occurrence and soil water tableare unpredictable at riparian wetlands. These circumstances make cultivation of common bean in riparian wetland challenging. Afield experiment was conducted at post flooding period but soil water table was still less than 30 cm below soil surface duringtransitional period from wet to dry season, in May to August 2017. Site location was a paddy field at Sungai Selincah Village, withinriparian wetland ecosystem in South Sumatra, Indonesia. The paddy field is characterized by alluvial soil and periodically flooded for4-6 months during rainy season. Raised beds were constructed for setting up water table positions at 10, 15, and 20 cm below soilsurface. Results of this study indicated that common bean (Phaseolus vulgaris L.) could tolerate soil water table at depth of 15 cmor deeper without significant decrease in growth and yield. However, soil water table at depth of 10 cm significantly reduced plantheight, number of trifoliate leaves, diameter of canopy, shoot dry weight, root length, number of primary lateral roots, chlorophyllcontent index (CCI) during reproductive stage, total number of pods, and cumulative yield. In conclusion, it is possible to growcommon bean at riparian wetland ecosystem as early as soil water table has subsided to 15 cm below soil surface duringtransitional period from wet to dry season.
