Abstract. Saputri DA, Agustrina R, Irawan B, Yusnita. 2026. Recovery of deteriorated upland rice seeds through ultra-low magnetic field exposure and its effects on germination and enzyme activity. Asian J Agric 10 (1): g100138. https://doi.org/10.13057/asianjagric/g100138. Aged upland rice (Oryza sativa L. var. Lumbung Sewu Cantik, LSC) seeds often exhibit reduced germination capacity and metabolic activity due to prolonged storage. Pretreatment with a low-intensity static magnetic field (magnetopriming) demonstrated the potential to revitalize and improve the quality of aged seeds. This study examined the effect of a low-intensity static magnetic field (magnetopriming) at 0.2 mT on the germination performance and enzyme activity of 10-month-old LSC seeds. Seeds were exposed to the magnetic field at different exposure durations, with untreated seeds as controls. Several germination indices and enzyme activities were evaluated. The results showed significant improvement in Final Germination Percentage (FGP) at optimal exposure durations, with no substantial changes were observed in Mean Germination Time (MGT), First Day Germination (FDG), Last Day of Germination (LDG), Coefficient of Velocity of Germination (CVG), Germination Index (GI), Germination Rate Index (GRI), and Time Spread of Germination (TSG). Enzyme assays revealed that α-amylase and protease activities were significantly increased following magnetic field exposure, whereas dehydrogenase activity showed only slight, non-significant enhancement. The study demonstrates that low-intensity magnetic field exposure can serve as an eco-friendly, non-chemical priming method that partially enhances the performance of aged seeds and improves early seedling vigor. Within the scope of this study, the observed improvements in germination and enzyme activity suggest that this non-chemical approach may support more efficient seed utilisation under sub-optimal storage conditions.

Abstract. Omran ZS, Mohsin RA, Al-Ani EH, Dayem TAA, Salih ZT. 2026. Green synthesis of silver nanoparticles using Dodonaea viscosa extract and their antibacterial activity against Escherichia coli and Staphylococcus aureus. Asian J Agric 10 (1): g100155. https://doi.org/10.13057/asianjagric/g100155. Silver nanoparticles (AgNPs) have attracted considerable attention as alternative antimicrobial agents, and plant-mediated synthesis represents an eco-friendly approach that minimizes the use of hazardous chemicals. In this study, Dodonaea viscosa AgNPs were examined to evaluate its activity against Escherichia coli and Staphylococcus aureus comparing to aqueous and ethanol extract. The phytochemical profile of the extract was analyzed by GC-MS, comparative analysis of both extracts indicated that aqueous extract contained a higher relative abundance of biologically relevant polar compounds. This observation supported its selection for subsequent green synthesis and antibacterial assays. The synthesized nanoparticles were characterized using FTIR, SEM, AFM, and EDX to confirm the functional groups involved in nanoparticle capping, as well as their morphology, particle size, and elemental composition. Antibacterial activity was evaluated against Gram-negative E. coli and Gram-positive S. aureus using the agar well diffusion method. The biosynthesized AgNPs, prepared from 0.5 and 1 mM AgNO₃, exhibited inhibition zones ranging from 16 to 29 mm, demonstrating enhanced antibacterial activity compared with the crude aqueous and ethanolic extracts. Overall, these findings indicate that D. viscosa-mediated AgNPs represent a promising eco-friendly antibacterial nanomaterial with improved efficacy. Future studies should include increased biological replication, robust statistical validation, and cytotoxicity assessment on mammalian cell lines to support potential biomedical translation.

Abstract. Anggadhania L, Rizqiani KD, Krisnawati, Novriyanti E, Adalina Y. 2026. Responses of Tetragonula sapiens and T. clypearis to biotic and abiotic factors in Central Lombok, Indonesia. Asian J Agric 10 (1): g100157. https://doi.org/10.13057/asianjagric/g100157. Tetragonula spp. meliponiculture in Indonesia's dry tropical regions faces significant challenges from biotic and abiotic variables. This comparative study evaluated the responses of Tetragonula sapiens and T. clypearis to temperature, humidity, food availability, and pest occurrence in Central Lombok, Indonesia. Seventy colonies (35 per species) were monitored monthly for five months (July-November 2018) in two shaded demonstration blocks under managed conditions. Colony weight change (ΔW) was quantified as a proxy for colony development, while ambient temperature, relative humidity, and floral abundance were recorded concurrently. Multiple Linear Regression (MLR) analyses explored associations between ΔW and environmental variables at the block level (n = 5 monthly means per species), and separate simple regressions were fitted for each species. Colony weight change showed species-specific associations with environmental variables. Across both species, ambient temperature exhibited a stronger statistical association with ΔW than relative humidity. However, these relationships were based on a very small number of monthly observations and should be interpreted as exploratory. T. clypearis showed steeper negative associations with increasing temperature and decreasing relative humidity than T. sapiens, suggesting greater sensitivity to microclimatic variation within the observed range. In contrast, food availability was more strongly associated with colony weight dynamics in T. sapiens (R² = 0.819) than in T. clypearis (R² = 0.496). Pest inspections identified Psocoptera (Tapinella sp.) in the hives, marking the first documented case of this species in Central Lombok, associated with propolis discoloration and fungal growth. Within the limitations of the small dataset and the block-level design, microclimate and food availability were strongly associated with colony development in Tetragonula spp., during the dry season. These results highlight the importance of integrated floral, microclimate, and pest management for sustainable meliponiculture in Central Lombok.

Abstract. Fivintari FR, Nurmalita, Ikhsan J, Mulyono, Ekawati FI, Yunanto, Ardila RA. 2026. Efficiency of shower and sprinkler irrigation system on curly red chili in coastal area Kulon Progo, Indonesia, using a stochastic frontier approach. Asian J Agric 10 (1): g100161. https://doi.org/10.13057/asianjagric/g100161. Coastal agriculture faces significant production challenges due to sandy soil characteristics, limited water retention, and increasing pressure on water resources. Improving irrigation efficiency is therefore essential to enhance productivity and sustainability in these environments. This study aims to evaluate the technical efficiency of curly red chili production under shower and sprinkler irrigation systems in the coastal area of Kulon Progo, Indonesia. The analysis employs a Cobb–Douglas production function estimated using the Stochastic Frontier Analysis (SFA) approach, which allows for the separation of random shocks and technical inefficiency in agricultural production. Both irrigation groups were technically efficient, with average technical efficiency levels above 0.7. However, sprinkler irrigation was more efficient than shower irrigation, with average scores of 0.902 and 0.795, respectively. Overall, the curly red chili farming business can achieve a maximum production of around 82.2% by using a combination of various production factors, suggesting that output could still be increased by approximately 17.8% through better input management and technology adoption without expanding resource use. The findings further demonstrate that irrigation technology plays a critical role in determining production efficiency. In particular, sprinkler irrigation is found to be more technically efficient than shower irrigation, reflecting its advantages in water distribution and labor use in sandy coastal conditions. These results highlight the importance of appropriate irrigation system selection as a key strategy for improving farm performance in coastal agriculture. The study provides empirical evidence to support the promotion of more efficient irrigation technologies and targeted extension programs aimed at enhancing technical efficiency. Overall, the findings contribute to the literature on irrigation efficiency in coastal farming systems and offer practical insights for farmers and policymakers seeking to improve productivity under challenging environmental conditions.

Abstract. Alatas RR, Munir AR, Bahrun AH. 2026. Determining priority strategies for chili agribusiness development through an integrated strategic analysis framework in Tolitoli District, Indonesia. Asian J Agric 10 (1): g100160. https://doi.org/10.13057/asianjagric/g100160. Chili pepper (Capsicum spp.) is a strategic horticultural commodity in Indonesia due to its high consumption level and significant influence on food price stability. In Tolitoli District, despite favorable agroclimatic conditions, chili productivity remains substantially below the provincial average (1.14 ton ha compared with 6.43 ton ha at the provincial level in 2023), while recurring price volatility contributes to regional inflation, reaching 7.21% year-on-year in 2024. These challenges are associated with weak farmer institutions, limited bargaining power, and fragmented agribusiness integration. This study aims to analyze internal and external factors, formulate alternative development strategies, and determine priority strategies for chili agribusiness development in Tolitoli District. A descriptive-exploratory mixed-methods approach was employed, integrating qualitative and quantitative data collected from key stakeholders. Data were analyzed sequentially using the Internal Factor Evaluation (IFE) matrix, External Factor Evaluation (EFE) matrix, Grand Strategy Matrix, and SWOT analysis, followed by prioritization using the Analytical Hierarchy Process (AHP). The results indicate that chili agribusiness development is positioned in Quadrant I of the Grand Strategy Matrix, reflecting a strong competitive position and high growth potential. Institutional support emerges as the most influential criterion in determining strategic priorities. The development of area-based chili production centers, aligned with land potential and market demand, is identified as the top priority strategy. The AHP results demonstrate acceptable consistency, with a consistency ratio (CR) below the threshold of 0.10. These findings highlight the importance of strengthening institutional coordination and promoting integrated, cluster-based agribusiness development to enhance competitiveness, stabilize prices, and ensure long-term sustainability of chili agribusiness in Tolitoli District.

Abstract. Alangood ZT, Al-Fahad MA. 2026. Effect of Trichormus variabilis biomass concentration and application method on cucumber growth under Cucumber Green Mottle Mosaic Virus (CGMMV) infection. Asian J Agric 10 (1): g100154. https://doi.org/10.13057/asianjagric/g100154. This study evaluated the effect of cyanobacterium Trichormus variabilis biomass on cucumber (Cucumis sativus) performance under Cucumber Green Mottle Mosaic Virus (CGMMV) infection in open-field conditions. Viral infection was confirmed using CGMMV-specific ImmunoStrip assays prior to treatment application. The experiment was arranged in a factorial design including three concentrations of T. variabilis dried biomass suspension (50%, 75%, and 100%) and three application methods (seed soaking, foliar spraying, and soil drenching), in addition to healthy and infected controls. Biomass concentrations significantly influenced disease severity, disease incidence, chlorophyll content (SPAD), fruit weight, and fruit firmness. The 75% concentration consistently reduced disease severity and incidence and improved physiological and yield-related traits compared with the 50% concentration. For several parameters, no significant differences were detected between the 75% and 100% concentrations, indicating a plateau response at higher biomass levels. Application method had limited influence on most measured traits. Differences in hydrogen peroxide (H₂O₂) accumulation were observed using a potassium iodide (KI)-based qualitative assay, indicating relative variation in oxidative status among treatments. The study was conducted during a single growing season, at one field location, and on a single cucumber cultivar, further multi-environment validation and standardized biomass characterization are required before making broader recommendations can be made. Overall, T. variabilis biomass at an intermediate concentration mitigated CGMMV-associated disease symptoms and improved cucumber productivity under the tested conditions.

Abstract. Truc NT, Nhung DTC. 2026. Sodium alginate-coconut oil edible coating delayed postharvest senescence and enhanced antioxidant capacity of lemon (Citrus latifolia) fruit. Asian J Agric 10 (1): g100156. https://doi.org/10.13057/asianjagric/g100156. Postharvest quality deterioration of lemon fruit is closely associated with physiological metabolism and oxidative stress during storage. This study investigated the efficacy of Sodium Alginate (SA) and Coconut Oil (CO) coatings, applied individually or in combination, in regulating physiological metabolism, oxidative stress, and antioxidant defense responses of lemon fruit during ambient storage. Fruits were assigned to four treatments (Control, SA, CO, and SA-CO) using a completely randomized design with three replicates per treatment. Coated and uncoated fruits were stored at 25℃ for 18 days, and key physiological (moisture loss, color), biochemical (vitamin C, total phenolics), reactive oxygen species (ROS), and antioxidant enzyme indicators were periodically evaluated. Relative to the control, the combined SA-CO coating markedly delayed deterioration. By day 18, SA-CO treated fruit showed weight loss of about 14%, which was roughly 2.5 percentage points lower than the control. Chlorophyll degradation was reduced, with SA-CO fruit retaining around 185 mg kg-1 chlorophyll, approximately 40 mg kg-1 higher than the control. Antioxidant compounds were better preserved, with vitamin C maintained at nearly 0.29 g kg-1 and total phenolics reaching about 0.15 g GAE kg-1, both slightly higher than the control. The coating also improved antioxidant enzyme regulation. At the end of storage, SOD activity in SA-CO fruit was close to 29 U mg-1 protein, substantially lower than the control, whereas APX and CAT activities increased by about 12 U mg-1 and 25 U mg-1 protein, respectively. Correspondingly, reactive oxygen species decreased, with superoxide radicals recorded at around 1.5 mmol NO₂ kg-1 s-1 and hydrogen peroxide at about 0.8 µmol H₂O₂ kg-1, both noticeably lower than the control. Overall, the combined SA-CO coating most effectively mitigated physiological degradation, improved antioxidant defense responses, and reduced oxidative stress, thereby supporting better retention of postharvest quality in lemon fruit stored under ambient conditions.

Abstract. Escomen EO, Mapandi ARM, Ambos AJA, Jose FKNJS, Ouano AC, Ambos AL, Jalova Jr. MC. 2026. Characterization, classification, and crop suitability of selected soils in the Ramain Subwatershed, Philippines. Asian J Agric 10 (1): g100153. https://doi.org/10.13057/asianjagric/g100153. Sustainable agricultural development requires site- and soil-specific technologies. This study aimed to characterize, classify, and assess the land suitability of select soils in the Ramain Subwatershed, Philippines, derived from three representative pedons. Reconnaissance surveys, soil pedon identification and preparation, soil sampling, and physico-chemical analyses were conducted on select areas within the Ramain Subwatershed. Three representative pedons were analyzed through field characterization and physico-chemical analyses, followed by classification using the USDA Soil Taxonomy and land evaluation based on the FAO framework coupled with the parametric square-root method. Land suitability assessment of the three representative pedons indicated that no areas were highly suitable (S1) for the selected crops. Oil palm and banana showed moderate suitability (S2; LSI up to 67.19 and 56.68, respectively), primarily limited by drainage and soil texture. Several crops, including sugarcane and mango, were classified as marginally suitable (S3) due to constraints in texture and organic carbon. Meanwhile, Arabica coffee and cocoa were not suitable within the evaluated pedons because of combined climatic and physico-chemical limitations. These overarching constraints-particularly poor drainage, strong soil acidity, and low phosphorus availability-highlight the limitations of blanket agricultural recommendations and emphasize the necessity of targeted amelioration strategies to enhance productivity and sustainability.

Abstract. Asruddin, Nadja RA, Salam M, Arief AA. 2026. Determinants and allocative efficiency of milkfish (Chanos chanos) production in polyculture systems in Pangkep District, Indonesia. Asian J Agric 10 (1): g100159. https://doi.org/10.13057/asianjagric/g100159. The use of polyculture systems in milkfish (Chanos chanos) farming is implemented to increase productivity and improve farmers’ income. This study aims to analyze the technical factors affecting milkfish production and to determine the allocative efficiency of the combination of production inputs used by farmers. The research was conducted in Pangkep District, South Sulawesi Province, Indonesia, during the 2023 production cycle. Primary data were collected through structured interviews using questionnaires with 117 milkfish farmers applying polyculture farming systems. A Cobb-Douglas production function was employed to examine the factors influencing milkfish production per production cycle, while an allocative efficiency analysis evaluated the ratio of marginal value product to input price (MVP/Px). The variables observed included land area, seed stocking, additional feed, fertilizer, medicines, labor, and capital. The results show that land area, seed stocking, additional feed, fertilizer, and labor have a positive and statistically significant effect on milkfish production (p < 0.05), whereas medicines and capital do not show a significant effect. The allocative efficiency analysis indicates that several production inputs have not yet been utilized at economically optimal levels. The estimated optimal input levels per farm per production cycle include a land area of 2.117 ha, seed stocking of 15,874 fish, additional feed of 978.528 kg, fertilizer of 318.991 kg, and labor of 45.447 man-days. These findings suggest that improving the allocation of key production inputs could enhance production performance and economic efficiency in milkfish polyculture farming systems
