Wed, 01 Oct 2025 00:00:00 +0000

Peppermint (Mentha piperita L.) is a herbaceous plant belonging to the genus Mentha and family Lamiaceae. Peppermint essential oil is used in pharmaceuticals, cosmetics, and flavoring. To evaluate the growth and quality of peppermint essential oil grown in polyhouse in Ho Chi Minh City, a two-factor experiment was arranged in a completely randomized block design (RCBD). The two factors were the harvesting method (C) and the density (M). The results showed that the optimal planting density was 25 plants/m2 (20 cm × 20 cm) when it combined with harvesting twice, resulting in 467,2 leaves and a fresh yield of 3,492 kg/ha. The essential oil composition was found to be 83.3% Menthol, 7.2% Pulegone, and 6.4% Isomenthone when harvested for the first time, and a yield of 3,314 kg/ha, 365.4 leaves, 83.7% Menthol, 6.8% Pulegone, and 4.7% Isomenthone when harvested for the second time.

Le Van Nam, Nguyen Tien Dung, Hoang Thi Hong Que, Hoang Gia Hung — Wed, 01 Oct 2025 00:00:00 +0000

Climate change poses major challenges to Vietnamese agriculture, requiring stronger adoption of sustainable technical practices (STPs). This study surveyed 337 farming households in four communes of Hue City to assess the current situation and identify factors influencing the adoption of STPs in crop production. Results indicate that eight types of STPs are commonly applied, including composting organic fertilizers, water-saving irrigation, VietGAP/organic production, integrated pest management (IPM), use of bio-products, crop rotation/intercropping, soil improvement with biological agents, and recycling of agricultural by-products. Among these households, 45.7% adopted at least one STP and reported higher average incomes than non-adopters. Multiple regression analysis (R² = 0.587) revealed four factors with significant positive effects on adoption: knowledge of climate change (β = 0.411), farm size (β = 0.254), participation in community organizations (β = 0.182), and access to credit (β = 0.137). The study recommends enhancing climate change awareness, improving agricultural extension services, strengthening farmer organizations, and refining credit policies to expand the adoption of sustainable practices.

The role and level of community participation in sustainable tourism development in the coastal lagoon areas of Hue city

Wed, 01 Oct 2025 00:00:00 +0000

This study delves into how local residents participate in sustainable tourism development in the coastal lagoon areas of Hue City. Through a survey of 315 households and interviews with experts, it clarifies the roles and levels of community contribution, as well as the benefits and challenges they face. The findings indicate that 49,84% of households participate at a basic level, primarily by providing products and services. However, the community-based tourism model has yielded significant benefits, including increased income, improved infrastructure and job creation. It has also contributed to preserving traditional cultural values and raising environmental awareness. Notably, the community demonstrated strong resilience to shocks like the COVID-19 pandemic, with many households quickly recovering and growing stronger. Based on these findings, the study proposes several solutions for more sustainable community tourism development: enhancing local residents' capacity, diversifying tourism products and refining policies to encourage active participation from the community.

Application of GIS in assessing the overlap between land use planning and forest planning in the mountainous area of Hue city

Nguyen Dinh Tien, Nguyen Van Binh, Nguyen Huu Ngu — Wed, 01 Oct 2025 00:00:00 +0000

This study was conducted in eight communes of the mountainous area of Hue city after the administrative merger of two levels, with the aim of assessing the overlaps between land use planning and forest planning during the 2021 – 2030 period. Based on the collection of planning data, GIS technology was applied to overlay maps, combined with expert consultation. The results indicate that the total overlapping area reached 18,850.23 ha, accounting for 10.29% of the study area; the matched area was 156,946.95 ha (85.63%); while the area with administrative boundary inconsistencies was 7,479.87 ha (4.08%). The communes of A Luoi 4, A Luoi 1, and A Luoi 5 recorded the largest overlapping areas, reflecting complex topography and boundaries. The identified causes of overlaps include: inconsistencies in administrative boundaries, differences in objectives and timing of planning, limitations in databases and mapping methods, and impacts from planning adjustments.

Study on the effects of soaking and germination on certain properties of red beans (Vigna angularis)

Wed, 01 Oct 2025 00:00:00 +0000

Germination is an effective bioprocess for improving the nutritional value of seeds. This study evaluated the effects of soaking time and temperature on germination rate, and the effects of germination conditions on enzyme activities in adzuki beans (Vigna angularis). Amylase and cellulase activities were determined using the 3,5-dinitrosalicylic acid (DNS) assay at 540 nm, and protease activity by the Folin–Ciocalteu method at 750 nm. Free amino acids and sugars were analyzed by GC–MS following trimethylsilylation (TMS). Soaking at 35 °C for 6 h yielded the highest germination rate (97.13%). Germination at 25 °C for 36 h produced peak hydrolytic enzyme activities. Under these germination conditions, several amino acids increased markedly—L-glutamic acid (278.95%), L-alanine (242.71%), L-valine (504.88%), L-threonine (437.63%), and 4-aminobutanoic acid (75.58%)—whereas glycine decreased by 27.85% compared with raw seeds. After germination, new free amino acids appeared (L-leucine, L-isoleucine, L-proline, serine, L-aspartic acid, and phenylalanine). Total soluble sugars decreased in germinated seeds relative to raw seeds, while glucose, fructose, and D-psicose increased. These findings provide a basis for developing germinated adzuki bean products with enhanced nutritional value.
