Abstract

The marketing of fresh fruit bunches of oil palm is an important part of the agribusiness supply chain. The main problem in fresh fruit bunches marketing is farmers’ dependence on collectors. This study aims to analyze the decision-making patterns of oil palm farmers in choosing marketing channels and to analyze the factors that influence oil palm farmers’ decisions to sell fresh fruit bunches through collectors. This study employs a quantitative approach using a survey of 50 oil palm farmers in Rukam Village, Mendo Barat Subdistrict. Respondents were selected through purposive sampling based on the fresh fruit bunches marketing channels they utilized. This study uses descriptive analysis to describe the characteristics of the respondents and the decision-making patterns of farmers in choosing fresh fruit bunches marketing channels, as well as binary logistic regression analysis to examine the influence of each independent variable on the probability of farmers’ decisions in choosing marketing channels. The results of the study indicate that the marketing patterns for fresh fruit bunches among smallholder oil palm farmers are still dominated by sales through collectors. Social relationships emerged as the most influential factor affecting farmers’ decisions to sell their fresh fruit bunches through collectors in Rukam Village, Mendo Barat Subdistrict. These findings reinforce the perspective that smallholder oil palm farmers’ decisions regarding the marketing of their fresh fruit bunches are not entirely determined by economic factors and physical access, but are also influenced by the social relationships formed within local marketing networks.

Abstract

This study was conducted to determine the in vitro regeneration response of synthetic potato (Solanum tuberosum L.) plantlet seeds to different concentrations of chitosan nanoparticles and MS medium. The study was conducted at the Plant Physiology and Biotechnology Laboratory of Sultan Ageng Tirtayasa University from December 2025 to April 2026. This study used a factorial randomized block design (RAK) consisting of two factors. The first factor was chitosan nanoparticle (C) with levels of concentration were 0 ppm, 50 ppm, 100 ppm, 150 ppm. The second factor was MS medium (T) with levels of ½ MS, ¼ MS, 0 MS. The results showed that the number of germinated seeds in the 50 ppm + ½ MS medium treatment combination yielded a higher average value of 0.6 seeds. Plant height showed that the 150 ppm + ½ MS medium treatment had the best effect, at 1.05 cm. The success rate of synthetic seed regeneration reached 26.7% in the 50 ppm + ½ MS medium treatments. The study showed that neither treatment had a significant effect on any of the observed parameters.

Abstract

The development of high-yielding and well-adapted maize hybrids is essential for ensuring the sustainability of maize production in Indonesia. This study aimed to evaluate yield performance, adaptability, stability and downy mildew resistance of the hybrid candidate BAY233 across different agroecological environments. Multilocation trials were conducted during 2023-2024 planting season at ten testing locations representing major maize-production regions in Indonesia. The experiment was arranged in a randomized complete block design with six replications. BAY233 evaluated alongside with BAY234 and two commercial check varieties, BISI959 and NK7328. Yield performance was analyzed using analysis of variance (ANOVA), while genotype x environment (GxE) interaction and stability were assessed using the Additive Main Effects and Multiplicative Interaction (AMMI) model. Resistance to downy mildew was evaluated through artificial inoculation using Peronosclerospora philippinensis and P. maydis. BAY233 produced grain yields ranging from 8.43 to 12.40 t ha⁻¹ across test locations. Although its stability was slightly lower than that of BAY234 but still categorized as promising hybrid due to its performance. BAY233 demonstrated superior yield performance and broad adaptability. Furthermore, BAY233 exhibited strong resistance to downy mildew, as indicated by its low incidence under artificial inoculation test. These findings suggest that BAY233 is a promising hybrid candidate for commercial release and cultivation in Indonesia owning to its high yield potential, broad adaptability, and disease resistance.

Abstract

Potato (Solanum tuberosum L.) cultivation in medium-altitude regions faces the primary challenge of high temperatures that inhibit stolon initiation and tuber formation. This study aimed to determine the effect of hilling above mulch and the application of growth retardants prohexadione-Ca and paclobutrazol on the growth and production of Medians potato cultivar at medium altitude. The experiment was conducted from October 2025 to February 2026 at PT. Central Horti Agro Makro, Cisurupan District, Garut, West Java (±800 m asl) using a Split Plot Design. The main plot consisted of hilling treatments (b₁: no mulch, no hilling; b₂: hilling without mulch; b₃: mulch without hilling; b₄: mulch with hilling) and the subplot consisted of retardant types (r₀: no retardant; r₁: prohexadione-Ca 100 ppm; r₂: paclobutrazol 100 ppm), replicated three times. Results showed that paclobutrazol 100 ppm significantly suppressed plant height at 60 DAP (33.20 cm) compared to prohexadione-Ca (37.80 cm) and the control (42.21 cm). No significant differences were observed among treatments for leaf area index (1.23 – 2.00). The b₄ treatment produced the highest total stolon count (15.33) and tuber number (12.89 knols plant-1). Prohexadione-Ca 100 ppm yielded the highest tuber number per plant (11.83 knols), while paclobutrazol 100 ppm produced the highest tuber weight per plant (178.11 g). The b₄ treatment also yielded the highest tuber weight (260.11 g plant-1), demonstrating a synergistic effect between mulching, hilling, and retardant application in improving potato production at medium altitude.

Abstract

Potato plantlet acclimatization is a critical stage that determines plant survival and growth after transfer from in vitro to ex vitro conditions. The selection of suitable growing media and nutrient supply is important to support plantlet adaptation and development during this stage. This study aimed to evaluate the growth responses of potato plantlets to different growing media and Murashige and Skoog (MS) medium concentrations during acclimatization. The experiment was conducted at the Agroecology Laboratory, Faculty of Agriculture, Universitas Sultan Ageng Tirtayasa, from December 2025 to February 2026. A split-plot design was used with two factors. The main plot consisted of growing media, namely rice husk charcoal, cocopeat, and perlite, while the subplot consisted of MS medium concentrations of 0, ¼, ½, and 1 MS. Each treatment was replicated three times. Growth observations included plant height increment, number of leaves, and number of shoots. Data were analyzed using analysis of variance followed by Duncan’s Multiple Range Test at the 5% level when required. Cocopeat produced the highest plant height increment at 6 weeks after transplanting, reaching 1.78 cm. Plantlets supplied with 1 MS medium concentration produced the highest number of leaves at 3 weeks after transplanting, with 2.60 leaves, and the highest number of shoots at 5 weeks after transplanting, with 0.56 shoots. The results indicate that plantlet growth during acclimatization was influenced by both the physical properties of the growing media and nutrient availability. The use of cocopeat and an adequate MS medium concentration can therefore be considered to support potato plantlet growth and improve acclimatization performance under ex vitro conditions.

Abstract

Drought is a primary constraint to global maize (Zea mays L.) production, and both biochar amendments and bacterial plant growth-promoting rhizobacteria (PGPR) have shown potential to mitigate its effects. However, no maize-specific meta-analysis has quantified whether these interventions act synergistically. Following PRISMA 2020 guidelines, we searched Scopus and Web of Science, identified 1,270 records, and after systematic screening selected 148 studies (52 biochar-only, 55 bacteria-only, 41 combined) from 28 countries (2009-2026). Preliminary random-effects meta-analysis of 87 effect sizes from 16 studies with complete variance data showed that amendments significantly improved multiple drought tolerance indicators. Bacterial inoculation increased measured outcomes by 26.8% (95% CI: 15.8-38.8%, p < 0.001), while biochar improved them by 5.4% (95% CI: 3.1-7.8%, p < 0.001). Significant improvements were detected for chlorophyll content (+58.8%), root length (+31.4%), relative water content (+20.3%), shoot dry weight (+16.8%), and photosynthetic rate (+14.2%). Substantial heterogeneity (I2 = 78-100%) across most outcomes indicates strong moderation by experimental conditions. These findings directly contribute to Sustainable Development Goal 2 (Zero Hunger) and SDG 13 (Climate Action), SDG 6 (Clean Water and Sanitation), SDG 12 (Responsible Consumption and Production), and SDG 8 (Decent Work and Economic Growth). This study provides a comprehensive framework and preliminary quantitative evidence supporting the use of integrated biochar-bacteria strategies for drought-resilient maize production, with full results forthcoming upon completion of data extraction from all 148 studies.

Abstract

This research was conducted at the Hasanuddin University experimental farm, Moncongloe District, Maros Regency, South Sulawesi with two main objectives: (1) to determine the effect of acidic dry soil stress on genetic diversity and heritability values ​​of agronomic traits of corn plants and (2) to characterize candidate hybrids tolerant to acidic dry soil stress based on the production response of corn genotypes .Method: this study used 88 genotypes with a randomized block design adopted as an experimental design. The parameters in this study were: soil chemical properties, observation of plant characteristics, and analysis of stress tolerance index. Based on the results of this study, it can be concluded that: (1) dry acidic soil stress has an effect on the phenotype and low to moderate values ​​on the heritability of plants with the characters of 10 cob weight, cob length, and productivity having relatively higher values ​​than other characters. (2) Genotypes G62 and G86 occupy the intersection between high yields under optimum conditions (Yp), high yields on acid soils (Ys), and high STI values. Both genotypes are capable of maintaining high yields, namely 8.8–9.0 t ha⁻¹ at optimum conditions and 7.5 t ha⁻1 on acid soils. These characteristics reflect the ideal profile in breeding corn tolerant to acid soils.

Abstract

Indonesia's cocoa production has experienced instability in recent years, highlighting the need to improve productivity through intensification and extensification strategies. The success of these approaches is highly dependent on the availability of high-quality seedlings. Therefore, the utilization of coconut water as a natural plant growth regulator and supplementary nutrient source has potential to enhance cocoa seedling growth. This study aimed to evaluate the effects of different doses and application frequencies of mature coconut water applied as a foliar spray on cocoa seedling growth and to determine the most effective treatment combination. The experiment was conducted from December 2025 to May 2026 at the Ciparanje Experimental Field, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, located at an altitude of approximately 752 m above sea level. A Randomized Block Design (RBD) consisting of ten treatments and three replications was employed. Treatments comprised combinations of mature coconut water doses of 10, 15, and 20 mL plant⁻¹ applied at intervals of 7, 14, and 21 days, while a 0.2% urea treatment served as the control. Observed variables included plant height, stem diameter, and leaf number. The results showed that foliar application of mature coconut water significantly increased cocoa seedling stem diameter at 6–10 weeks after treatment. In addition, variations in coconut water dose and application frequency were able to support plant height and leaf production with effectiveness comparable to that of the inorganic fertilizer treatment (urea). For stem diameter, the application of 10, 15, and 20 mL plant⁻¹ resulted in significantly greater values than the control treatment. Among the tested application intervals, the 21-day interval was found to be the most effective.

Abstract

The surprising fact that the Sinta index publications declined in 2025 and the insignificant achievement in 2026 was significant. This study aimed to discuss effective strategies for increasing scientific publications. This qualitative study employed observation, and interviews to collect data, followed by phenomenological interpretation. The results indicate that academics in the 2023-2024 period were highly motivated in research and scientific publication, but their motivation weakened in the 2024-2025 period. The factors contributing to this decline, including the main factors, are discussed, and appropriate strategies are proposed. This study concludes that there is significant potential for academics, both lecturers and students, to continue productively increasing the number of scientific publications, not only in quantity but also in quality, as an effort to develop science, technology, and knowledge in Indonesia.

Abstract

Global food security is increasingly threatened by abiotic stresses, particularly waterlogging, which poses significant challenges to cereal crop production. Waterlogging is one of the primary abiotic stresses that significantly influence the interrelationships among plant physiology, growth, and yield. This review aims to examine the relationships among these three aspects in cereal crops, with an emphasis on the response mechanisms to waterlogging stress. Findings from the reviewed literature indicate that waterlogged conditions induce hypoxia in the root zone, leading to reduced photosynthetic rates, impaired nutrient uptake, and increased production of reactive oxygen species (ROS), which trigger cellular damage. These effects result in reduced plant growth and yield. Nevertheless, plants exhibit various adaptive mechanisms, such as aerenchyma formation, adventitious root development, and proline accumulation, which enhance tolerance to stress. Variations in tolerance levels among cereal species also influence the extent of yield reduction. Overall, improving plant tolerance to waterlogging stress requires an integrated approach through physiological understanding, genetic improvement, and the application of appropriate agronomic management.
