“…This stunted shoot growth is presumed to be associated with limited aerobic rhizosphere for roots to develop as indicated by shorter and less branching roots (Table 5). In previous pot experiment, shallow water table condition at depth around 13.5 cm or deeper for up to 12 days was tolerable by common bean as indicated by no significant reduction in root dry weight, CCI, RLER, pod yield, number of pods/plant, average pod weight, and pod size (Lakitan et al, 2018). Based on results of these two experiments, it is fair to assume that critical depth of water table for common bean plant is between 10 and 13.5 cm.…”

“…However, results of recent pot experiment indicated that common bean could tolerate shallow soil water table at depth around 13.5 cm below surface of growing substrate for up to 12 days as indicated by no significant reduction of pod yield, number of pods/plant, average pod weight, pod size, root dry weight, chlorophyll concentration index (CCI), and relative leaf expansion rate (RLER) (Lakitan et al, 2018). Moreover, Lakitan et al (2018) observed that roots of common bean were unable to survive within water saturated condition below soil water table, but the plants were able to compensate for the root loss by increasing root biomass within aerobic substrate above water table. Oxygen and moisture availability at upper rhizosphere contributed to the ability of the bean plants to tolerate shallow water table.…”

Common bean is a susceptible vegetable to excessive water condition in soil. Meanwhile, flooding occurrence and soil water table are unpredictable at riparian wetlands. These circumstances make cultivation of common bean in riparian wetland challenging. A field experiment was conducted at post flooding period but soil water table was still less than 30 cm below soil surface during transitional period from wet to dry season, in May to August 2017. Site location was a paddy field at Sungai Selincah Village, within riparian wetland ecosystem in South Sumatra, Indonesia. The paddy field is characterized by alluvial soil and periodically flooded for 4-6 months during rainy season. Raised beds were constructed for setting up water table positions at 10, 15, and 20 cm below soil surface. Results of this study indicated that common bean (Phaseolus vulgaris L.) could tolerate soil water table at depth of 15 cm or deeper without significant decrease in growth and yield. However, soil water table at depth of 10 cm significantly reduced plant height, number of trifoliate leaves, diameter of canopy, shoot dry weight, root length, number of primary lateral roots, chlorophyll content index (CCI) during reproductive stage, total number of pods, and cumulative yield. In conclusion, it is possible to grow common bean at riparian wetland ecosystem as early as soil water table has subsided to 15 cm below soil surface during transitional period from wet to dry season.

“…Munir et al (2018) reported that inhibition of root extension was associated with increase of ethylene in roots and high CO2 concentration entrapped within rhizosphere due to slow diffusion of these molecules in water; however, the most damaging effect, even causing death of root tips, was due to O2 deficiency. Short-term or partial exposure to WSR did not set off permanent effect to roots in some plants, as Lakitan et al (2018b) reported that roots were able to regrow after water-saturated condition gradually diminished.…”

“…While affordable technologies have been developed for crop cultivation during flooding period (rainy season), including floating culture system (Lakitan et al, 2019b;2019c;Ramadhani et al, 2018); crop cultivation after rice harvesting at riparian wetlands still need much more efforts to be further explored and developed. Some researchers have conducted studies for overcoming those agronomic constraints, including gradual soil drying due to prolonged dry season (Widuri et al, 2017; or for anticipating probable early rainy season which causing shallow water table (Susilawati and Lakitan, 2019;Lakitan et al, 2018b;Meihana et al, 2017) or flooding (Lakitan et al, 2019c;2018c). The aim of this study was to enrich our understanding on physiological responses of chili pepper to water-saturated rhizosphere and relating this acquired knowledge to our previous findings in agronomic researches.…”

Morpho-physiological responses of chili peppers (Capsicum annuum) to short-term exposure of water-saturated rhizosphere

Chili pepper is frequently grown by local farmers at riparian wetland during dry season in Indonesia. However, during the last decade, unpredictable distribution and intensity of rainfall have increasingly threatened chili pepper production at the wetlands due to untimely water-saturated rhizosphere (WSR) occurrences. WSR is a condition when all pores within root zone were filled with water. This condition can be simulated by adding water into growing substrate until a thin layer of water was visible above substrate surface. Two Indonesian varieties (Laris and Romario) and one Japanese variety (Takanotsume) were used in this study. Aim of this study was to evaluate morpho-physiological effects of short-term (4 days) WSR exposure in chili pepper. Results of this study revealed that roots suffered more than aerial organs as indicated by the increase of shoot/root ratio from 4.56 at pre-exposure to 7.03 at end of the exposure. Total leaf area significantly reduced since larger older leaves were replaced by newly developed smaller leaves. Relative water content (RWC) in all organs was decreased, but did not reach a detrimental level. Leaf RWC was decreased from 83.6% at pre-exposure to 77.8% after the exposure; however, leaf RWC was able to rebound to 81.5% after 7 days of recovery. Photosynthetic and transpiration rates sharply decreased, associated with decrease in stomatal conductance during WSR exposure. Chlorophyll fluorescence also sharply declined. Gas exchange parameters did not significantly recover after 7 days of recovery in all varieties. Meanwhile, SPAD values were not affected by WSR exposure.

Despite its large acreage, riparian wetland has been underutilized in Indonesia. Intensity of agricultural activities on this wetland was very low mainly due to two unfavorable extremes, i.e. unpredictable occurrence of flooding during rainy season and drought during dry season. Relevant, affordable, and acceptable technologies are required as solution to this problems. The technologies should be developed based on actual needs, preferences, and absorptive capacity of smallholder farmers, to ensure adoption. Objective of this study was to explore needs, preferences, and absorptive capacity of smallholder farmers through direct observation on their farming practices and dialogs on constraints in intensifying food production at riparian wetlands in Indonesia. The study was conducted at five villages in riparian wetland ecosystem in South Sumatera, Indonesia, from January to June 2016. This qualitative research was conducted in two stages: started with no-preconception Grounded Theory procedure; then, followed by questionnaire-guided survey. Results of this study indicated that intensive observation on farmer's practices and dialogs on constraints in intensifying food production could reveal needs, preferences, and absorptive capacity of smallholder farmers. Observed farmers' practices include land preparation and soil quality improvement, seedling preparation, transplanting, cropping management, and harvesting. Dialogs disclosed that unmanageable constraint but urgently needed by smallholder farmers in intensifying food production was technology solution for uncertain and uncontrollable natural flooding and drought occurrence at riparian wetlands. Government intervention is expected for constructing infrastructure for water management at riparian wetlands, i.e. polder system.
