Jajar legowo 4:1 cropping pattern has been adopted by rice farmers; however, there has been limited information on the comparison between internal and edge rows. In addition, the effects of timing and frequency of fertilizer applications on rice cultivated at riparian wetland also have to be understood. In this research, both single and split applications of fertilizer were employed. The single fertilizer applications were applied at 15 days after transplanting (DAT) (T1), 30 DAT (T2), 45 DAT (T3); and the split applications were 15+30 DAT (T4), 15+45 DAT (T5), 30+45 DAT (T6), and 15+30+45 DAT (T7). Results of this research indicated that crops in the edge rows produced higher leaf area index but those at internal rows produced higher dry weight biomass. Split fertilizer application to three times (T7) increased the weight of grains and number of filled spikelet but did not affect other shoot and root growth traits. Overall, fertilizer application increased leaf chlorophyll and nitrogen content. Jajar legowo 4:1 planting pattern and split fertilizer application to three times are recommended for increasing yield in rice cultivated at riparian wetlands.

The riparian wetland offers potential for horticultural crop cultivation, such as chili peppers. It is important to consider cultivation techniques and the use of organic matter to improve soil properties, particularly to combat waterlogging during the rainy season. This study aimed to assess the impact of biochar application on the growth of chili peppers (Capsicum annuum L.) during the vegetative stage under waterlogging conditions. This research was conducted at the experimental land of the Agrotechnology Department, Faculty of Plant and Animal Sciences, Universitas Bina Insan from December 2022 to February 2023. This research employed a complete randomized design (RAL) factorial with two factors. The first factor involved waterlogging stress, including control (C) and waterlogging stress (W). The second factor (N) encompassed the application of biochar, namely without biochar (N0), rice husk biochar (N1) and coconut shell biochar (N2) at a dose of 200 g plant-1. The results showed that waterlogging conditions (W) and biochar application (N) showed significantly different results in shoot length, root length, number of leaves, and total dry weight of chili plants, while the interaction (WxN) showed significantly different in shoot length and root length of plants. Treatment without biochar (N0) in waterlogging conditions actually showed shoot length, root length, number of leaves and total dry weight of plants that were significantly higher than treatment coconut shell biochar (N1) and rice husk applications (N2).

Generally, vegetables cultivation in tropical riparian wetland is conducted only one times per year simultaneously or after rice cultivation. One of constrains of cultivation in tropical riparian wetland is low adoption to technology which can be used by local farmers during dry season. The objective of this research was to introduce result of research to local farmer directly and examine the local farmer’s adoption about the technology based on research to apply in tropical riparian wetland, Pemulutan, South Sumatera. Based on this research, results showed that farmers' interest in cultivating vegetables during the dry season is still low, but it has a chance to be improved. Alternative solutions through watering and adjustment of environmental conditions or adaptation through the selection of cultivation locations and the selection of various types of vegetable crops have been carried out by farmers. However, the application of mulch has not been practiced by farmers in tropical riparian wetland for vegetable cultivation during the dry season due to limited information received, considered as capital intensive, and the sociocultural aspects of the local community.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 659–666). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Oil palm (Elaeis guineensis Jacq.) is one of Indonesia's leading plantation commodities. The current extensification efforts of oil palm plantations are positively correlated with the increasing need for quality oil palm seedlings. The most important management practice related to the seedling process is optimal fertilization. This study aimed to determine the growth response of oil palm seedlings in ex-coal mine soil media through the application of biological fertilizers. The research was conducted in Bingin Teluk Village Road, Rawas Ilir District, North Musi Rawas Regency, South Sumatra Province in February-May 2024. This research was conducted using a one-factor randomized group design (RAL) with 4 levels of biofertilizer treatment consisting of control / no treatment (P0), Trichoderma 15g /plant fertilizer (P1), Gliocladium 15g/plant fertilizer (P2), and Mikoriza 15g/plant fertilizer (P3). The results showed that the biofertilizer treatment gave significantly higher results in plant height, number of leaves and leaf area of oil palm seedlings compared to those without biofertilizer treatment. Gliocaldium fertilizer 10g/plant gave the best results on the growth of oil palm seedlings in ex-coal mine soil compared to Tricoderma and Mycorrhiza fertilizer.

Agronomic constraints for vegetable cultivation in riparian wetlands are low soil quality and shallow water table conditions. This study aims to identify the effect of biochar application and shallow water table on proline accumulation and plant growth of bean leaf (Phaseolus vulgaris L.) at the generative stage. This study was carried out from April to August 2018 in factorial randomized block design. The first factor was doses of biochar (0, 1, and 2 kg.m-2), and the second was shallow water table condition (20 cm and 10 cm below the soil surface) given in the generative stage. The results showed that biochar application and the shallow water table significantly affected leaf parameters; proline accumulation and increases in the sucrose levels occurred on the leaves. Proline content increased started at 3 days after treatment (DAT) and decreased at 6 DAT until recovery day (7 DAT). The biochar application of 2 kg.m-2 provided good aeration in the soil, which enhanced the bean's ability to survive under excess water. Proline accumulation is one of the adaptation mechanisms of beans to abiotic stress in shallow water table conditions.

Under suboptimal conditions, plants generally respond differently to survive. Plant responses include changes in morphology, anatomy, and physiology. This study aimed to investigate the response of eggplant to lack of oxygen due to shallow water table and waterlogging in the generative stage and explored their adaptability to be cultivated in riparian wetlands. This research was conducted from October 2017 to January 2018 in an experimental pond in the village of Demang Lebar Daun Palembang and at the Postgraduate Integrated Laboratory, Faculty of Agriculture, Sriwijaya University, Palembang. This study used a randomized block design with a shallow water table and waterlogging treatments: control (field capacity), water tables of 13 cm, 8 cm, and 3 cm below the soil surface (bss), and waterlogging 2 cm above the soil surface. The results showed that the water table 3 cm bss and waterlogging decreased the relative rate of leaf expansion, specific leaf fresh weight, and specific leaf water content. On the sixth day of the waterlogging treatment, the chlorophyll content decreased by 31.29%. On the other hand, the proline content in the leaves reached the highest level of concentration. After the sixth day, the chlorophyll content increased while the proline content decreased, and the eggplant recovered. Water table 3 cm bss and waterlogging caused the formation of aerenchyma tissue in the roots, which started one day after the treatment. Eggplant is an adaptive crop with a fairly high tolerance for shallow water tables and waterlogging. Keywords: adaptation, aerenchyma, proline, riparian wetland, tolerance

Vegetable cultivation in tropical riparian wetland is currently suboptimal due to unpredictability of water dynamics. Chili pepper is a fruity vegetable that is often cultivated in tropical riparian wetland but is often constrained by conditions of excessive water saturation, such as shallow water tables, waterlogging and submergence in the transition period (dry to rainy season). The aim of this research was to study the morpho-agronomy of varieties of chili peppers under waterlogging stress during the early vegetative stage. A Plot Design was used in this experiment. The main plot consisted of (1) control (field capacity, regularly watering) and (2) waterlogging (simulated by adding water to the growing substrate until a thin layer of water was visible above the substrate surface during four days, followed by a seven-day recovery time during seven days). The subplot consisted of three chili pepper varieties, namely Laris, Romario, and Takanotsume (Japanese variety). Results of this study revealed that waterlogging stress significantly affected root length, number of leaves, total leaf area, chlorophyll content (SPAD), root fresh weight, shoot fresh weight, root dry weight, and shoot dry weight after stress and after recovery time. Meanwhile, chili pepper varieties were only significantly affected the total leaf area and chlorophyll content (SPAD). The total dry weight of Romario and Takanotsume before stress, after stress and after recovery did not significantly increase under waterlogging stress, whereas the total dry weight of Laris was precisely increased, indicating that vegetative growth is continuing. The Laris was categorized as one of chili pepper varieties that had medium tolerance to waterlogging stress at the early vegetative stage. Keywords: Capsicum annum L., soil plant analyses development, total dry weight, waterlogging
