Abstract. Zalama MT, Leilah AAA. 2025. Predicting soybean seed longevity under ambient storage through multivariate viability and vigor analysis. Asian J Agric 9: 702-711. The current study examined the longevity of the soybean seed cultivar (Giza 111) under ambient storage conditions in Dakahlia, Egypt, from July 2023 to June 2024. Three lots of seed from different sources were observed for up to 360 days to predict seed longevity and to determine storage parameters for warehouse management. Initial seed quality was estimated, then a simplified viability equation, v = Ki - (1/?) P, was applied to predict seed longevity during the storage period. Significant differences were noticed among seed lots. Seed lot 01 (Legumes Department, FCRI, ARC) exhibited the best seed viability, with the highest storage index (? = 120 days), longest half-viability period (P50 = 151 days), and slowest deterioration rate (tg? = -0.0008), indicating superior vigor during storage. In contrast, seed lots 02 and 03, obtained from the private sector, showed reduced viability, with Lot 03 exhibiting the lowest (? = 90 days, tg? = -0.011, P50 = 79 days). Linear regression showed seed viability decline rates differed: Lot 01 (slowest, -2.50), Lot 02 (moderate, -2.73), and Lot 03 (fastest, -3.34), confirming relative deterioration speeds. Pearson correlation analysis showed a strong positive correlation between probit viability and seed vigor indices, including germination (r = 0.946), accelerated aging (r = 0.945), seedling dry weight (r = 0.925), and vigor index II (r = 0.935). Quantitative data further supported the correlation between probit viability and vigor parameters. This study demonstrated that a simplified viability equation effectively predicted the longevity and vigor of soybean seeds from different sources stored under ambient conditions in Dakahlia, Egypt. Significant differences in viability and deterioration rates among seed lots underscore the equation's value for practical seed storage monitoring, improved ambient storage management, and enhanced seed inventory control and quality preservation through accurate performance prediction.

Abstract. Bakhtiyar M, Anvar M, Diloram I, Arzigul T, Ismoil R. 2025. Genotype × diet interaction in Uzbek breeds and hybrids of the silkworm (Bombyx mori) for enabling year-round sericulture. Asian J Agric 9: 808-817. Sericulture in Uzbekistan faces seasonal limitations due to dependence on fresh mulberry leaves, limiting cocoon production to one or two cycles per year. This study evaluated the interaction between genotype and diet type in ten Bombyx mori genotypes—five pure breeds (Ipakchi-5, UzNIISH-9, Ipakchi-1, Gulshan, and Nafis) and five hybrids (Zarafshon, Gulshan × Nafis, Oltin Vodiy, Kumush Tola, and Navruz)—to assess adaptability to artificial feeding for year-round sericulture. Larvae were reared on four diets: freeze-dried mulberry leaves, convectively dried leaves, a Japanese standard artificial diet, and natural leaves as a control. Biological and technological traits were analyzed using two-way ANOVA (Diet × Genotype) and Tukey’s HSD test. Results showed significant effects of both diet and genotype (p<0.001). The freeze-dried mulberry diet ensured the highest survival (86-90%), cocoon weight (1.7-1.85 g), and silk ratio (18.5-20.3%), statistically comparable to natural feeding. Hybrids Gulshan × Nafis and Navruz exhibited superior adaptability and physiological stability, confirming strong genotype × environment interaction. The study demonstrates that locally developed freeze-dried diets enable sustainable, year-round, and industrially scalable sericulture in Uzbekistan, supporting both traditional textile and emerging biomedical applications of silk.

Abstract. Andriansyah, Fathir A, Antika LT. 2025. Effect of mung bean sprout (Vigna radiata) germination phases on the physical and sensory quality of nata de coco. Asian J Agric 9: 787-799. The use of natural nitrogen sources in nata de coco production is essential to enhance food safety and promote sustainable fermentation practices. This study evaluated the effect of mung bean sprout (Vigna radiata) germination phases 24 hours (F1), 48 hours (F2), and 72 hours (F3) as natural nitrogen sources on the physical and sensory properties of nata de coco. Sprout extracts were mixed with coconut water and sugar, inoculated with Acetobacter xylinum at a density of 1×10⁸ CFU/mL, and fermented for 15 days. The observed parameters included thickness, weight, total soluble solids, and sensory attributes (aroma and taste) assessed using a three-point hedonic scale. Statistical analysis revealed no significant differences (p>0.05) among germination phases in all measured parameters, although the 48-hour treatment tended to produce nata with slightly better physical and more balanced sensory characteristics. These findings indicate that within the 24-72-hour window, sprout physiological maturity only modestly affects nitrogen availability, suggesting that the use of sprout extract itself as a natural nitrogen source is more influential than germination duration. Overall, this study reinforces the potential of mung bean sprout extract as a safe, eco-friendly, and sustainable alternative to synthetic nitrogen sources in microbial cellulose production, supporting the development of environmentally responsible food biotechnology.

Abstract. Labonete HJP, Fulgencio BKR, Abatay MP, Ampang MP, Ancheta DJ, Gumal SJR, Jimenez EA, Modina RMR, Yongco JE, Tabugo SRM. 2025. Design, optimization, and validation of corn-strain-specific primers for fall armyworm (Spodoptera frugiperda) detection in the Philippines. Asian J Agric 9: 844-853. The fall armyworm Spodoptera frugiperda (Lepidoptera: Noctuidae) is an invasive pest that threatens corn production in the Philippines. The presence of morphologically identical corn- and rice-strains, each with distinct host preferences, complicates accurate identification. Molecular diagnostics are significant in understudied regions of the country, such as Mindanao where S. frugiperda invasions are rapidly expanding, with primers offering reliable support in pest surveillance. This study developed and optimized corn-strain-specific primers (FAWC1–FAWC5) using ancestral Cytochrome Oxidase I (COI) haplotypes (GenBank U72974, U72976) and Primer3 in Geneious Prime (v2023.2.1). In silico PCR and specificity assessments confirmed optimal primer characteristics (20-22 bp, 57.5-60.3 °C Tm, 50-55% GC), amplicon sizes of 100-250 bp, and absence of secondary structures. The standardized annealing temperature for amplification is 53.7°C to ensure efficient primer binding and workflow consistency. The applied step-wise experimental validation ensured that all primer sets adhered rigorous technical standards supported by wet-lab testing which narrowed the best-performing candidates to FAWC3, FAWC4, and FAWC5. Verification using larval samples collected from corn and rice fields in Davao Oriental and corn fields in Iligan City demonstrated reliable amplification. It confirmed the dominance of the corn-strain across the tested sites, strengthening geographic validation and consistency in primer performance fit for community-level monitoring FAWC4 exhibited broad corn-strain detection capability making it suitable for initial screening, while FAWC5 provided strong lineage-specific resolution within Philippine populations. Together, these primers form a dual-function molecular toolkit that enables accurate strain-level identification, strengthens regional monitoring programs, and supports evidence-based fall armyworm management strategies in Philippine corn-growing regions.

Abstract. Rahmadhani SE, Salsabila S, Andrianto R, Rosyida SH, Ainia Q, Dewangga A, Setyawan AD. 2025. Diversity and potential invasiveness of insects in agricultural landscapes of Wonosobo, Central Java, Indonesia. Asian J Agric 9: 663-670. Altitude and microclimatic variation act as key ecological filters that shape species diversity, community structure, and invasion potential altitude, microclimate, and land-use intensity jointly structure insect communities in the agricultural landscapes of Wonosobo, Central Java, Indonesia. Surveys across lowland Karangsambung (621 masl), mid-elevation Blederan (969 masl), and highland Sembungan (2,056 masl) recorded 57 species from 31 families, revealing clear diversity gradients. Species richness and functional balance peaked at mid-elevation, where moderate temperatures and heterogeneous vegetation supported diverse herbivores, predators, and pollinators. Lowland sites retained high diversity driven by warm conditions and productive cropping systems. In contrast, highland assemblages were simplified and dominated by synanthropic Diptera (Musca domestica, Leucostoma simplex), reflecting harsh climatic filters and nutrient-enriched soils. NMDS-envfit analyses highlighted altitude, temperature, illumination, and wind as the main determinants of community structure. Invasiveness remained low overall, but disturbance-tolerant taxa increased with elevation. These findings emphasize the importance of vegetation heterogeneity, microclimate buffering, and biological control in sustaining ecological stability. As climate warming accelerates, mid-elevation agroecosystems may become critical resilience zones for conserving biodiversity and maintaining agricultural sustainability.

Abstract. Gil-Marín JA, Zermeño-González A, Córdova-Rodríguez MX, Ramírez-Rodríguez H, Melendres-Alvarez AI, Moreno LS, Khamkure S. 2025. Evapotranspiration and the crop coefficients of black bean (Phaseolus vulgaris L.) with weighing lysimeters. Asian J Agric 9: 349-357. The water needs of a crop depend on the weather conditions, crop characteristics, and stage of development, which are represented by the crop coefficient (Kc), whose values change throughout the crop's stages of development. This understanding is the result of a meticulous research process, ensuring the reliability of these findings; knowing the crop evapotranspiration is essential to improving water use efficiency. This study aimed to determine the values of the crop evapotranspiration (ETc) and Kc for a black bean crop using a weighing lysimeter under greenhouse conditions. The research was conducted in the greenhouse of the graduate program in Tropical Agriculture at the University of Oriente (UDO), located on the Juanico Campus in Maturín, Monagas State, Venezuela, during the dry season from March to June 2020, on an Ultisol soil. The results showed that the bean's daily rate of evapotranspiration (ETc) was 3.16, 6.31, 8.37, and 4.80 mm day-1 for the initial growth, vegetative, flowering, and maturity stages, respectively. The evapotranspiration for the complete growing cycle was 458.31 mm, corresponding to a water volume of 4,583.10 m³ ha-1. The crop coefficient (Kc) for each development stage was 0.51 for the initial stage (10 days), 0.88 for the vegetative stages (35 days), 1.20 for the flowering stage (20 days), and 0.85 for the maturity stage (8 days).

Abstract. Dewi SS, Supangkat G, Hastomo T. 2025. Comparison of starch-based liquid sugar production from local cassava. Asian J Agric 9: 683-688. Indonesia's rising sugar demand and dependence on imports have sparked interest in alternative sweeteners sourced from local crops. The country currently imports a significant portion of its sugar, leading to concerns about food security and economic stability. Cassava (Manihot esculenta), widely cultivated across the country, offers a promising raw material for liquid sugar production due to its high starch content and accessibility. This study evaluates the suitability of three cassava varieties; Cartiva 25, Melati, and Randu for liquid sugar production using enzymatic hydrolysis. The process involved liquefaction with ?-amylase followed by saccharification with glucoamylase. Carbohydrate content in the resulting liquid sugar ranged from 76.15 to 80.39%, with Randu and Melati outperforming Cartiva 25. Reducing sugar levels was highest in Randu (65.10%), indicating more efficient starch conversion. Sensory analysis revealed that Randu produced the sweetest and lightest-colored liquid sugar. However, none of the samples met Indonesian National Standards for colorlessness and odorlessness due to the absence of purification steps. While starch yield did not differ significantly among varieties, biochemical and sensory profiles suggest that varietal selection plays a critical role in optimizing sugar output and product quality. Randu and Melati varieties demonstrated superior performance and are recommended for industrial-scale processing. To meet national standards and enhance market viability, future production should incorporate purification techniques such as decolorization and deodorization. These findings offer practical guidance for processors and farmers, highlighting cassava's potential to reduce reliance on imported sugar and support sustainable agriculture. Promoting high-performing varieties like Randu and Melati could strengthen local supply chains and contribute to Indonesia's food system resilience.

Abstract. Enano JD, Balderas MB. 2025. Yield and postharvest response of ‘Rosanna’ tomato to radiation-modified carrageenan and vermicompost tea. Asian J Agric 9: 339-348. Tomatoes are one of the perishable crops, and inappropriate postharvest handling leads to a high amount of postharvest losses. The study investigated the effect of Radiation-Modified Carrageenan (RMC) and Aerated Vermicompost Tea (AVCT) on yield, fruit quality, and postharvest attributes in ‘Rosanna’ tomatoes. The study was laid out in a randomized complete block design consisting of seven treatments and three replicates and used the least significant difference test at a 5% level. Significant differences shown in fruit color at 20 Days from Initial Storage (DIS) (p = 0.0380); fruit firmness on 5 DIS (p = 0.0332), 15 DIS (p = 0.0099), and 25 DIS (p = 0.0291). Postharvest disease incidence at 14 DIS (p = 0.0115), 28 DIS (p = 0.0314); and postharvest disease severity index at 42 DIS (p = 0.0106), 56 DIS (p = 0.0416), and 72 DIS (p = 0.0297). No significant differences in other parameters; however, the 20,000 ppm RMC has the earliest day to harvest and the highest total yield. Fruits with the highest total soluble solids, titratable acids, and TSS/TA ratio at 40,000 ppm RMC + AVCT, 20,000 ppm RMC, and 20,000 ppm RMC + AVCT, respectively. The 1:1 (v:v) AVCT to water has the highest moisture and lowest dry matter. The highest fruit polar and equatorial diameter at 40,000 ppm RMC + AVCT. Fruits with the highest fruit color scale on 20,000 ppm RMC + AVCT at 5 DIS, and 20,000 ppm RMC at 10, 15, and 25 DIS. Firmer fruits in 1:1 (v:v) AVCT to water at 10 DIS, and 30,000 ppm RMC + AVCT at 20 DIS. The 10,000 ppm RMC + AVCT has the lowest percentage of disease incidence, the lowest severity index, and extended storage shelf life. The application of 10,000 ppm RMC + AVCT improved the fruit quality and extended the shelf life of the fruits.

Abstract. Cahyadi MA, Yunus A. 2025. Antioxidant profile of several local rice varieties from Central Java, Indonesia, under biotic stress conditions of bacterial leaf blight. Asian J Agric 9: 368-376. Central Java harbors diverse local rice germplasm that requires preservation, yet their resistance to bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) remains underexplored. Antioxidant activity has been linked to BLB resistance, indicating its potential as a screening tool for identifying tolerant varieties in breeding programs. This study examined four local rice varieties inoculated with Xoo, focusing on catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), total flavonoids, and total phenolic compounds. Based on lesion length, Mentik Susu (MS) and Rojolele (RL) were resistant, while Merah Segreng (MSeg) and Hitam Mutiara (HM) showed moderate resistance. At 5 days post-inoculation (dpi), the highest CAT activity (0.019 units/mg protein) occurred in MSeg, while at 20 dpi HM showed the highest (0.014 units/mg protein). For POD, RL exhibited the highest activity (0.271 units/mL protein) at 5 dpi, and MSeg at 20 dpi (0.436 units/mL protein). The highest SOD activity at 5 dpi was observed in HM (169.35 units/mg protein), whereas MS peaked at 20 dpi (157.95 units/mg protein). These enzymatic antioxidant levels did not differ significantly among varieties, but non-enzymatic antioxidants—flavonoids and phenolics—showed significant variation, with MS and RL containing 44.30 and 27.09% more flavonoids and 25.88 and 18.91% more phenolics, respectively, than moderately resistant varieties. These findings indicate that non-enzymatic antioxidants contribute more prominently to BLB resistance than enzymatic ones, and that varieties rich in flavonoids and phenolic compounds, such as Mentik Susu and Rojolele, have stronger resistance, highlighting their potential for breeding programs to enhance tolerance against bacterial leaf blight while supporting the conservation and utilization of Central Java’s local rice diversity.

Abstract. Kadir A, Suharno, Iswandi RM, Alwi LO. 2025. The evolution of agriculture in the Papua-Papua New Guinea frontier, Keerom District, Indonesia. Asian J Agric 9: 554-567. A community's socio-cultural characteristics influence how agricultural systems evolve to support livelihoods. In rural and inland areas, such as in Keerom District, Papua Province, Indonesia, food security is heavily reliant on the availability of natural resources. The local communities in Keerom maintain a hunting-gathering culture and the traditional agricultural systems. This study aims to determine how the agricultural sector in Keerom has developed to meet the needs of people on the border with Papua New Guinea. This includes introducing oil palm and corn as new efforts to develop superior commodities. A survey was conducted using qualitative research techniques and interview methods. The survey analyzed the social, economic, and ecological systems that underlie the evolution of livelihood systems in the region. Data were collected through in-depth interviews with traditional farmers, indigenous community leaders, migrant communities, and other stakeholders, supplemented by field observations. The findings reveal a significant shift in livelihood systems, rooted in evolutionary developments since the time of the ancestors of the Keerom community. This transformation is closely tied to the community's hunting-gathering culture, traditional agricultural practices, the introduction of modern agriculture, the establishment of oil palm plantations, and the implementation of the central government's food estate program. The study highlights that oil palm and corn cultivation present substantial economic opportunities, particularly in terms of income generation and infrastructure development. However, these benefits are accompanied by notable challenges, including shifts in traditional cropping patterns, land tenure conflicts, and adverse impacts on local biodiversity. This research contributes to a deeper understanding of how the integration of new commodities reshapes the agrarian and social landscapes in Keerom District. It also provides insights into the implications for sustainable agricultural development policies in the region, offering a promising path forward for the community and its stakeholders.
