Abstract. Garces JJC. 2026. Sustainable development goals and agricultural service subscriptions: Consumer behaviors in Cebu, Philippines. Asian J Agric 10: g100101. https://doi.org/10.13057/asianjagric/g100101 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. Sinong GF, Sahrir MAS, Yusoff N, Adiwena M, Ali NS, Ibrahim MH, Awang A, Rakib MRM. 2026. Weeds in oil palm plantations and their antifungal activity against Ganoderma boninense. Asian J Agric 10: g100102. https://doi.org/10.13057/asianjagric/g100102. Basal Stem Rot (BSR) caused by Ganoderma boninense remains the most destructive disease of oil palm, threatening global palm oil production. Current management strategies have proven largely ineffective in providing long-term disease control, highlighting the urgent need for sustainable approaches based on natural bioactive compounds. Plant-derived metabolites represent a promising alternative due to their natural antifungal properties, environmental safety, and potential compatibility with integrated disease management systems. Weeds, in particular, are often resilient to pathogens and may serve as unexplored reservoirs of bioactive compounds with antifungal potential. The present study aimed to identify weed species associated with healthy oil palm trees and evaluate their extracts’ in vitro antifungal properties against G. boninense. Three weed species, namely Hoya carnosa (W16), Ischaemum muticum (W18), and Polygala paniculata (W19), were found exclusively in association with healthy oil palm trees. Their crude extracts were evaluated in vitro against G. boninense using solvents of varying polarity. Among them, P. paniculata exhibited the strongest antifungal activity, with both aerial and below-ground parts showing pronounced inhibition. Below-ground part extracts consistently outperformed aerial parts, particularly when extracted with methanol, which yielded the highest inhibition and lowest EC50 values, suggesting a higher concentration of bioactive metabolites in root tissues. The observed antifungal efficacy correlated with solvent polarity, emphasizing the importance of targeted extraction in isolating effective phytochemicals. These findings indicate that P. paniculata, especially its methanolic root extract, represents a promising source of natural antifungal compounds. The study highlights the potential of weed plants as unconventional reservoirs of bioactive metabolites and provides a foundation for developing eco-friendly, broad-spectrum fungicides to combat G. boninense, thereby advancing sustainable disease management in oil palm plantations.

Abstract. Bustillos RG. 2026. Growth and mycoremediation activity of Panaeolus antillarum on lead-contaminated coconut water media. Asian J Agric 10: g100104. https://doi.org/10.13057/asianjagric/g100104. This study investigated the mycoremediation potential of lead (Pb) using the coprophilous mushroom Panaeolus antillarum cultivated in solid and liquid coconut water media. Mycelial growth performance, including mycelial diameter, dry biomass, and volume loss, was evaluated under different Pb concentrations of 1 ppm, 10 ppm, 100 ppm, and 1000 ppm using coconut water gulaman as solid medium and coconut water as liquid medium. In addition, Pb accumulation in the mycelia was quantified to assess bioaccumulation capacity. Statistical analysis showed that the highest mycelial diameter and thickness were recorded at 1 ppm Pb (77.0 mm), which was not significantly different from the control without Pb (79.50 mm). In contrast, no substantial mycelial growth was observed at 1000 ppm Pb, indicating strong inhibitory effects at high metal concentration. Among all Pb-contaminated treatments, the 1 ppm medium produced the highest mycelial biomass (1.82 g) and volume loss (8.52 mL). Maximum Pb bioaccumulation was significantly recorded at 100 ppm (268 mg/kg), whereas lower accumulation capacity was observed at reduced Pb concentrations, particularly at 1 ppm (11.0 mg/kg). Notably, the detectable Pb content in mycelia grown at 1000 ppm was attributed mainly to passive adsorption rather than active uptake, as excessive Pb levels severely suppressed biomass production. Overall, the observed tolerance to Pb stress and the ability to accumulate Pb indicate that P. antillarum exhibits substantial heavy metal resistance and mycoaccumulation potential, supporting its applicability in mycoremediation strategies for Pb-contaminated substrates.

Abstract. Ramdan EP, Giyanto, Hartono A, Hidayat SH, Widodo. 2026. Rhizosphere microbial functional traits associated with basal stem rot suppression in oil palm (Elaeis guineensis). Asian J Agric 10 (1): g100105. https://doi.org/10.13057/asianjagric/g100105. This study aimed to investigate the abundance, diversity, and functional characteristics of rhizospheric microbial communities associated with different levels of Basal Stem Rot (BSR) disease incidence in oil palm plantations, with the understanding that the observed relationships represent associations rather than causal effects. Rhizospheric microbial communities play an essential role in soil health and disease suppression in oil palm plantations. Fifteen composite soil samples were collected from three field blocks with low, moderate, and high BSR incidence in the Rejosari Unit, PT Perkebunan Nusantara VII, Lampung, Indonesia. Microbial populations were quantified using standard plate counts, while diversity indices were assessed using the Shannon-Wiener, evenness, and dominance indices based on morphospecies counts. The results showed that total microbial, bacterial, and fungal populations were significantly higher in soils with low disease incidence (4.99×10⁷, 4.94×10⁷, and 5.18×10⁵ CFU g-¹, respectively) compared to moderate and high categories. Soils with low BSR incidence also exhibited greater microbial and bacterial diversity (H′=1.07 and 0.74) and lower dominance, indicating a more balanced community structure. Non-pathogenic, antagonistic, and Volatile Organic Compound (VOC)-producing microbes predominated in low-incidence soils, contributing to natural disease suppression. LASSO regression identified VOC-producing and antagonistic microbes as predictors associated with BSR incidence, whereas correlation analysis revealed a significant negative association only for VOC-producing microbes (r=-0.60, p=0.02). Nitrogen-fixing microbes were positively associated with disease severity (r=0.63, p=0.01). Although causality was not tested, the results suggest that reduced BSR incidence was more closely associated with specific functional microbial groups, particularly VOC-producing microbes, than with overall microbial abundance or diversity, emphasizing that soil management strategies that support beneficial functional microbial groups may contribute to enhanced soil resilience.

Abstract. Ernawati, Syahidah, Mujetahid A. 2026. SWOT-AHP analysis of youth participation in South Sulawesi, Indonesia, palm sugar agroforestry. Asian J Agric 10: g100103. https://doi.org/10.13057/asianjagric/g100103. Youth disengagement from agroforestry-based livelihoods threatens the continuity of palm sugar production and the broader non-timber forest product economy in South Sulawesi, Indonesia. This study examines factors influencing youth participation in palm sugar agroforestry and prioritizes actionable strategies to strengthen youth engagement in the Universitas Hasanuddin Educational Forest (KHDTK) landscape. Data were collected through household surveys, semi-structured expert interviews, and field observations in Rompegading and Limapoccoe Villages. An integrated SWOT-AHP approach was applied to (i) identify internal and external factors shaping youth participation, (ii) formulate strategic alternatives, and (iii) rank strategies based on expert judgments and derived priority weights. The results highlight that the most influential strategic priorities focus on value-added product innovation and the expansion of digital/social-media marketing, supported by capacity building and institutional strengthening to improve product quality, coordination, and market access. Taken together, the results suggest that palm sugar agroforestry becomes more appealing to young people when it is framed as a market-oriented agribusiness, with roles beyond traditional production such as product development, branding, and online customer engagement. The prioritized strategy package provides practical guidance for local stakeholders. It highlights targeted, youth-focused interventions that upgrade palm sugar enterprises and strengthen the attractiveness and viability of agroforestry-based livelihoods.
