Abstract

Productivity of green mustard (Brassica juncea L.) and pak choi (Brassica rapa L.) is often constrained by suboptimal cultivation practices. Sound-based stimulation, such as Sonic Bloom, offers a novel approach to enhance plant growth, yet comparative evidence across sound types remains limited. This study evaluated the effects of Qur’anic recitation and classical music on the growth and yield of both crops. A Randomized Block Design with a non-factorial time-series approach was implemented from July to September 2022. Two plant species (J1: green mustard; J2: pak choi) and three treatments were tested: S0 (control), S1 (Qur’anic recitation), and S2 (classical music). Sound exposure (90 dB, 20–14,500 Hz) was applied daily for 2 hours, beginning 7 days after planting and continuing until harvest (24 DAP). Growth parameters and biomass were analyzed using ANOVA and Tukey’s HSD (5%). Classical music (S2) significantly enhanced early growth, with plant height increases reaching 102.08% in green mustard and 91.16% in pak choi (6–12 DAP). Green mustard consistently outperformed pak choi across stages (77.88% vs 60.92% at 12–18 DAP; 42.07% vs 27.72% at 18–24 DAP). Leaf number increased up to 44.12%, and leaf area reached 208.74% under S2. Qur’anic recitation (S1) showed stronger effects at later stages, including higher dry root weight (0.34 g). Chlorophyll content was higher in green mustard but was not significantly affected by treatments. Classical music promotes early vegetative growth, while Qur’anic recitation supports sustained development. Sound-based stimulation represents a promising, sustainable strategy to enhance leafy vegetable productivity.

Abstract

Despite the increasing use of earthworms for swine dung management, limited information exists on the comparative functional group composition and heavy metal reduction in vermicomposts produced by Eisenia fetida and Eudrilus eugeniae. This study characterized vermicompost from swine dung produced by Eisenia fetida and Eudrilus eugeniae. Pre-composted swine dung was vermicomposted for three months using 200 mature earthworms per 10 kg of substrate, with three replicates per species in a completely randomized design. The vermicomposts were analyzed for physicochemical properties and functional groups using Fourier transform infrared spectroscopy (FTIR). FTIR revealed the presence of -CH₂, -CH₃, -COO-, -C-O, and -C-O-C functional groups, indicating enrichment in organic acids and aliphatic compounds. Pb and Cd concentrations decreased substantially, from 32.0 and 0.07 ppm in raw dung to 7.0 and 0.004 ppm for E. fetida, and 7.0 and 0.008 ppm for E. eugeniae, respectively. These results demonstrate effective heavy metal reduction and functional group enhancement, suggesting that the produced vermicomposts may be suitable for agricultural use, subject to regulatory standards.

Abstract

Iron deficiency is a common limitation in alkaline soils, restricting nutrient uptake and yield in pulse crops such as green gram (Vigna radiata L.). To compare various iron fertilization regimes and their effects on soil properties, nutrient dynamics, and nutrient uptake in green gram, a field experiment was conducted from March to July 2024 at SGT University, Gurugram, Haryana. The experimental design was a randomized block trial with three replicates because the experiment comprised seven treatments, including the recommended dose of fertilizers (RDF: 20:40:40 kg N: P₂O: K₂O ha-1) and soil and foliar applications of FeSO4. It was found that foliar application of FeSO4 significantly enhanced soil fertility and plant nutrient status compared to soil application. The highest soil organic carbon was recorded at 30 and 45 DAS with the RDF + foliar spray of 0.6% FeSO4 (0.41% and 0.40%, respectively), an increase of about 32-35% compared with the control (0.31-0.30%). Likewise, the available nitrogen content increased by 189.12 kg ha-1 to 225.08 kg ha-1 (about 19 percent improvement) under the same treatment. Nutrient levels in plant tissues also increased significantly, and nitrogen content in the straw and grain improved by 40-120 percent and 1.82-3.38 percent, respectively, compared to the control. The experiment shows that foliar iron application is more effective than soil-applied iron in improving nutrient status and plant uptake in alkaline soil. The originality of the study lies in its comparison of soil under staged foliar iron fertilization and its effects on the dynamics of soil nutrients, micronutrient availability, and nutrient use efficiency in the growth of green grass on alkaline soils.

Abstract

Patchouli (Pogostemon cablin Benth) is a major essential oil crop widely used in pharmaceutical, perfumery, and aromatherapy industries. Despite Indonesia supplying most of the global demand, productivity and oil quality remain inconsistent across production regions. Although rice husk biochar and foliar fertilizers are individually known to enhance plant growth, their synergistic interaction and optimal combined dosage for patchouli production have not been clearly established, representing an important research gap. This study represents the first experimental attempt to determine the optimal combined dosage of rice husk biochar and foliar fertilizer for improving patchouli growth and oil yield. A Randomized Complete Block Design with two factors (three biochar levels and three foliar fertilizer levels) and 3 replicates was implemented from June to December 2023 in West Sumatra, Indonesia. Significant interaction effects were observed across major growth and yield parameters. The combination of 200 g plant⁻¹ biochar and 1 ml L⁻¹ foliar fertilizer produced the highest biomass accumulation and oil yield compared with other treatments. These findings provide empirical evidence of a synergistic fertilization effect and offer a cost-efficient nutrient management strategy to enhance patchouli productivity under smallholder farming conditions.

Abstract

Monoculture rice farming in subak institutions faces multidimensional risks that can threaten production stability and farmers' cash flow, yet empirical prioritization of these risks at the subak institutional level remains limited. This study aims to identify and prioritize risks in monoculture rice farming in Subak Munggu, Balı, using Failure Mode and Effect Analysis (FMEA) Primary data were collected through structured in-depth interviews and questionnaires from 30 purposively selected farmers supported by relevant secondary sources Qualitative information was used to compile and validate risk events and rak agents, while quantitative S-O-D scoring (1-10) was applied to calculate Risk Prionty Numbers (RPN) and determine priority risks The analysis identified eight risk events (E1-E8) and twelve risk agents (A1-A12) The highest priority rak agent was demand fluctuations (A1) with RPN 490, the only factor classified in the red (intolerable) zone followed by erratic weather and climate (A4 RPN 342), human error in cultivation and input use (A9 RPN 276) declining government subsidies (A10, RPN 224), and pests and diseases (AS RPN 236) Risk mapping indicates that most risks fall within the ALARP category with one dominant intolerable risk that may control overall business stability These findings imply that mitigation should prioritize market-demand rak management and its upstream linkages to seed and input procurement, alongside climate-adaptive practices and institutional strengthening to reduce exposure in monoculture systems in subak.

Abstract

Adlay production is constrained by its long seed-propagation maturity period, underscoring the need for alternative propagation methods. This study evaluated the effects of genotype and stem-cutting position on vegetative propagation of adlay. The experiment was conducted from November 2023 to January 2024 under screenhouse conditions at the BISU Bilar Campus, using a 2 × 3 factorial design with three replications in a completely randomized design. Two adlay genotypes (Gulian and Kiboa) and three stalk portions (basal, middle, and upper) were evaluated. Kiboa showed greater sprouting (1.78) and tillering performance (3.00) than Gulian. Stalk portion influenced all vegetative traits measured (p < 0.001). Basal cuttings exhibited the highest sprouting percentage (35%) and number of sprouts (4.00), while middle cuttings produced taller plants (155.34 cm) with more leaves (10.00), nodes (6.00), and tillers (5.00). These findings confirm that stem cuttings, particularly from the basal and middle portions, offer a practical and efficient method for rapid, uniform adlay propagation, supporting breeding programs, germplasm conservation, and improved availability of planting material for farmers.

Abstract

Ultisols are characterized by strong acidity, low cation exchange capacity, and high phosphate fixation, which limit nutrient availability and crop productivity. Sustainable fertilization strategies are needed to improve soil quality and reduce dependence on inorganic inputs. A pot experiment was conducted from January to August 2025 using a randomized complete block design with nine treatments and three replications (270 plants). Treatments included combinations of 50% NPK fertilizer with liquid organic fertilizers (LOFs) derived from goat urine, rabbit urine, banana peels, and pineapple peels. Data were analyzed using analysis of variance (ANOVA), followed by orthogonal comparison tests. The combined application of LOFs with 50% NPK significantly increased biomass, bulb yield, soil CEC, organic C, total N, available K, and plant N and K uptake (p < 0.01) compared to 100% NPK. Yield increased by 27.7%, while N and K uptake rose by 63.0% and 65.0%, respectively. Rabbit urine LOF showed the highest effectiveness, improving yield by up to 36.0% compared to goat urine. Plant-based LOFs enhanced soil organic C, CEC, and K availability, whereas animal-based LOFs were more effective in increasing soil N. The integration of LOFs with reduced NPK improves soil fertility and shallot productivity under controlled conditions. Rabbit urine LOF at 300 mL L⁻¹ is the most effective treatment. However, field validation is required before large-scale application.

Abstract

The use of organic fertilizers in horticultural farming remains limited due to farmers’ perceptions regarding effectiveness, practicality, and economic considerations. Understanding farmers’ preferences for organic fertilizer attributes is therefore important to support the adoption of sustainable agricultural practices. This study aims to analyze the preferences of Okiagaru Agricoop partner farmers toward organic fertilizer attributes in horticultural cultivation in Cianjur Regency, West Java. This study employed a descriptive quantitative approach using conjoint analysis to evaluate farmers’ preferences for different combinations of fertilizer attributes. Data were collected through field observations, questionnaires, and direct interviews with 30 partner farmers selected using purposive sampling. The attributes analyzed included price, quality, effectiveness, and ease of use. The results show that ease of use is the most influential attribute, with the highest importance value (30.397%) and utility estimate (0.542), indicating that farmers strongly prefer fertilizers that are easy to apply in farming activities. This was followed by quality (23.580%), effectiveness (23.093%), and price (22.930%). In addition, most farmers (96.67%) expressed their willingness to process organic waste into organic fertilizer. These findings indicate that practical and functional attributes play a crucial role in farmers’ decisions to adopt organic fertilizers. Therefore, the development and dissemination of organic fertilizer technologies should prioritize ease of application, effectiveness, and affordability to encourage wider adoption among horticultural farmers.

Abstract

Taro (Colocasia esculenta L.) is a tuber crop with high economic value and potential as an alternative food source, yet its productivity remains low due to declining soil fertility and low organic matter content. This study aimed to evaluate the effect of Mucuna bracteata organic mulch combined with reduced NPK fertilizer dosage and biofertilizer application on the vegetative growth of taro. The experiment was conducted at the Experimental Garden of the Faculty of Agriculture, University of Riau, from May to August 2025 using a non‑factorial Completely Randomized Design with five treatments and four replications. Observed parameters included leaf stalk length, number of leaves, leaf area, leaf area index, stem diameter, chlorophyll content, soil temperature, and soil moisture. The results indicated that 75% and 50% NPK fertilizer combined with biofertilizer and M. bracteata mulch produced vegetative growth comparable to that of 100% NPK fertilizer across most parameters. The use of M. bracteata mulch and biofertilizer reduced inorganic NPK fertilizer requirements by 25–50% without decreasing vegetative growth.
