Growth and morpho-physiological assessments of Indonesian red chili cultivars on early vegetative stage under water stress conditions: A comparison of waterlogging and drought Erna Siaga, Dwi S. Rini, Laily I. Widuri, Jun-Ichi Sakagami, Benyamin Lakitan, Shin Yabuta Chilean Journal of Agricultural Research, 2024 Red chili pepper Capsicum annuum L. var. annuum plants are one of the fruity vegetable types that are often cultivated in riparian tropical wetlands but are constrained by water stress such as waterlogging during rainy season and drought in dry season. The aim of this research was to evaluate the growth and morpho-physiological responses of red chili pepper cultivars subjected to waterlogging and drought stress conditions. The experiment was carried out in a strip-plot design with two factors. The first factor was three water stress treatments, namely control (field capacity), waterlogging, and drought. The second factor was six cultivars of Indonesian red chili pepper. The findings indicated that both waterlogging and drought stress had a detrimental impact on the reduction of the growth parameters of red chili pepper such as root, shoot and total dry weight. Chili pepper defended its root weights in response to drought stress (0.653 g plant -1 ) whereas it preserved shoot weight in response to waterlogging (0.913 g plant -1 ). In the morphological characters, chili pepper exhibited an increase in specific leaf area expansion in response to both waterlogging (150.82 cm 2 ) and drought (188.82 cm 2 ) compared to control (140.91 cm 2 ), but decreased specific leaf weight during stresses and recovered after 7 d in waterlogging. Leaf chlorophyll content (SPAD) and leaf relative water content (LRWC), as physiological characteristics, also experienced a decline during exposure to both waterlogging and drought during 8 d; yet, SPAD and LRWC able to recover completely at 7 d after waterlogging and drought treatment were terminated.
Changes of physiological traits on red chili pepper (Capsicum annum L.) exposed by short-term waterlogging E Siaga, D S Rini, J I Sakagami, S Yabuta, M Meihana, S M Lumbantoruan Iop Conference Series Earth and Environmental Science, 2024 Tropical riparian wetland known as non-tidal lowland is potential land for agriculture, especially for vegetable cultivation such as red chili pepper (Capsicum annum L.). Transitional period (dry to rainy season) has a chance for red chili pepper cultivation in the field (at low tide conditions), but has risk of experiencing dynamic water table to waterlogging in early rainy season. The aim of this research was to determine the effects of physiological traits of red chili pepper exposure on short-term (4 days) waterlogging. This study was done at the Tropical Crop Science Laboratory, Kagoshima University, Japan. The experiment was designed as a completely randomized factorial design. The first factor was control/field capacity and waterlogging (entire growing media was submerged). The second factor was chili variety, consisting of Laris and Romario. Treatments began 14 days after transplanting, lasted four days, then followed by seven days of recovery. The results of this study showed that there were changes in photosynthetic characters between before waterlogging, after waterlogging and after recovery time, between control and waterlogging, and also between Laris and Romario. Photosynthetic and transpiration rates decreased sharply under waterlogging in after waterlogging, but increased in after recovery period on Laris, opposite on Romario. Changes occur were associated with the decline in stomatal conductance and chlorophyll fluorescence as a response to waterlogging stress. Laris as a resistant variety has the ability to recover under short-term stress conditions, so it needs to be further developed for cultivation in tropical riparian wetlands.

Growth response and nutrition uptake of corn plants on drought stress in peat soil S M Lumbantoruan, M Paulina, E Siaga, S Aggraini, Febrianti Iop Conference Series Earth and Environmental Science, 2023 Peat soil has been exposed to drought so it cannot bind water (irreversible drying) and loses its function as soil. Peat soil will be dry organic soil cannot provide water to plants. In addition, drought stress as abiotic stress decreased the ability of the soil to hold roots so that plants can fall easily which is impacted by changing the physical and chemical properties of peat soil. The goal of this research was to acquire biofertilizer components that are optimized for increasing corn in drought-stress land and the sustainability of peat soils. This study was conducted inside the experimental land of Universitas Bina Insan, Lubuklinggau. The layout used in this study became a factorial randomized block design with two elements. The first element has been the biofertilizer method (F) with four stages, specifically: F0 = without mycorrhizae, F1 = Mycorrhiza + Petrobio, F2 = Mycorrhiza + Agrozeabiochar, F3 = Mycorrhiza + Pugam. The second element was the intensity of watering (P) includes 4 ranges, particularly: watering once a day, P2 = watering every three days, P3 = watering every five days, and P4 = watering every seven days. The results showed that the biofertilizer formula with mycorrhizal+petrobio (F1) treatment has significant effects in increasing plant height, plant dry weight, and nutrient uptake. Enhancement of nutrient uptake correlated with increasing the growth of corn plants on drought stress in peat soil, The intensity of watering, was significantly different in all treatments except for K nutrients uptake.

Lesser-known ethnic leafy vegetables talinum paniculatum grown at tropical ecosystem: Morphological traits and non-destructive estimation of total leaf area per branch Benyamin Lakitan, Kartika Kartika, Laily Ilman Widuri, Erna Siaga, Lya Nailatul Fadilah Biodiversitas, 2021 Lakitan B, Kartika K, Widuri LI, Siaga E, Fadilah LN. 2021. Lesser-known ethnic leafy vegetables Talinum paniculatum grown at tropical ecosystem: Morphological traits and non-destructive estimation of total leaf area per branch. Biodiversitas 22: 4487-4495. Talinum paniculatum known as Java ginseng is an ethnic vegetable in Indonesia that has also been utilized as a medical plant. Young leaves are the primary economic part of T. paniculatum, which can be eaten fresh or cooked. This study was focused on characterizing morphological traits of T. panicultaum and developing a non-destructive yet accurate and reliable model for predicting total area per leaf cluster on each elongated branch per flush growth cycle. The non-destructive approach allows frequent and timely measurements. In addition, the developed model can be used as guidance for deciding the time to harvest for optimum yield. Results indicated that T. paniculatum flourished rapidly under wet tropical conditions, especially if they were propagated using stem cuttings. The plants produced more than 50 branches and more than 800 leaves, or on average produced more than 15 leaves per branch at the age of nine weeks after planting (WAP). The zero-intercept linear model using a combination of two traits of length x width (LW) as a predictor was accurate and reliable for predicting a single leaf area (R2 = 0.997). Meanwhile, the estimation of total area per leaf cluster was more accurate if three traits, i.e., number of leaves, the longest leaf, and the widest leaf in each cluster were used as predictors with the zero-intercept linear regression model (R2 = 0.984). However, the use of a single trait of length (L) and width (W) of the largest leaf within each cluster as a predictor in the power regression model exhibited moderately accurate prediction at the R2 = 0.883 and 0.724, respectively.
Rice Husk Biochar Effects on Improving Soil Properties and Root Development in Rice (Oryza Glaberrima steud.) Exposed to Drought Stress During Early Reproductive Stage Kartika Kartika, Jun‐Ichi Sakagami, Benyamin Lakitan, Shin Yabuta, Isao Akagi, et al. Aims Agriculture and Food, 2021 <abstract> <p>Benefits of biochar application on environment conservation and agricultural production have been widely studied. However, few studies were focused on root development. The objective of this study covered root and shoot development, yield, and soil properties associated with exposure of <italic>Oryza glaberrima</italic> rice during the early reproductive stage to drought stress in rice-husk amended soil. The biochar was amended at a rate of 10.5 g pot<sup>-1</sup>, equivalent to 3 ton ha<sup>-1</sup>. Biochar-amended and non-amended plants were exposed to drought stress after the panicles had visibly emerged in all plant populations. Biochar application caused less restriction on root elongation, volume, and surface area during water stress conditions. Enhanced root development was primarily associated with improvement in water status and chemical properties in biochar-amended soil. Soil chemical properties improved, including increased soil pH, available P, cation exchange capacity, and exchangeable Mg. Under drought stress conditions, shoot growth was more sensitive than root growth, as indicated by the significant reduction of stem dry weight (SDW) and leaf dry weight (LDW). Fine roots in biochar-amended soil were longer than those in non-amended soil. In general, Biochar application enable the <italic>O. glaberrima</italic> rice to maintain yield under drought stress condition.</p> </abstract>
Short-term drought exposure decelerated growth and photosynthetic activities in chili pepper (Capsicum annuum L.) Laily Ilman Widuri, Benyamin Lakitan, Jyunichi Sakagami, Shin Yabuta, Kartika Kartika, Erna Siaga Annals of Agricultural Sciences, 2020 Chili pepper (Capsicum annuum L.) is a preferred vegetable by local farmers at a riparian wetland in Indonesia due to high market demand and its economic value. Chili pepper can be grown immediately after rice harvesting, concurrently with the early dry season. Three chili pepper varieties, namely Genie, Romario, and Laris were evaluated for their adaptability to drought condition. Drought treatment was imposed for 7 days until soil water potential was dropped to around −30 to −40 kPa. Morphological and photosynthetic traits were measured at pre-, during, and post-drought exposures. Growth analysis was calculated based on measured morphological traits. Results indicated that the number of leaves (NoL), total leaf area (TLA), total accumulated dry matter (TDM), and relative growth rate (RGR) were negatively affected by drought. Water content of shoot (SWC), leaf (LWC), and root (RWC) were significantly decreased during drought exposure; yet, able to fully recover at 7 days after drought treatment was terminated. Decrease in shoot root ratio (SRR) and leaf weight ratio (LWR); reversely, increase the root weight ratio (RWR) under drought condition, was not associated with enhancement of root growth. Rather, it was due to less negatively effect of drought on roots than on the above-ground organs. Simultaneously, chlorophyll fluorescence, LWC, stomatal conductance, transpiration and photosynthetic rates declined during drought exposure. However, 7 days after drought treatment was terminated, all traits were able to return to pre-drought levels. Among chili pepper varieties studied, Genie exhibited better overall performance than Laris and Romario did under drought stress condition.
