Abstract. Garces JJC. 2025. Sustainable development goals and agricultural service subscriptions: Consumer behaviors in Cebu, Philippines. Asian J Agric 9: 861-869. As the Philippines faces growing challenges in food insecurity and unsustainable consumption, this study explores why many Cebuano consumers who support the Sustainable Development Goals (SDGs) are not actively participating in agricultural subscription services. These services, which connect consumers directly with local farmers, offer a promising way to promote sustainable food systems. Through a survey of 488 respondents across Cebu Island, the study identified three types of consumers: (i) General subscribers, (ii) Price-conscious consumers, and (iii) Quality-focused consumers. General subscribers showed the strongest sustainability alignment, with 58% actively minimizing food waste, compared to 29% of price-conscious consumers and 34% of quality-focused consumers, while regression and chi-square results identified age group, marital status, and education level as significant determinants of subscription. These findings conclude that consumer subscription behaviors are shaped not only by affordability and product quality considerations but also by the degree of alignment with sustainability values, emphasizing that stronger integration of SDG-oriented practices corresponds to more consistent participation in agricultural subscription services.

Abstract

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.
