Growth and biomass yield of tropical grass varieties across seasons in Hue city

Tran Ngoc Liem — 2026-03-31

Five tropical grass varieties—Ruzi, Mulato II, Purple, Mombasa, and Mun River—imported from Thailand were cultivated in Hue city to evaluate their growth performance and biomass yield across multiple harvests during the year. The experiment was arranged in a randomized complete block design (Randomized Complete Block Design-RCBD) with four replications for each variety. The establishing period lasted 105 days after sowing the seeds, and subsequent regrowth harvests were carried out at 45-day intervals. Monitoring from September 2022 to December 2023 (one initial harvest and eight regrowth harvests) revealed significant differences in growth and biomass yield among the varieties (p<0.05). Purple, Mombasa, and Mun River had greater plant heights than Ruzi and Mulato II, whereas Ruzi and Mulato II produced more leaves and tillers (p<0.05). Biomass yields of Mombasa, Mun River, and Purple were higher than those of Mulato II and Ruzi (p<0.05). Growth and biomass yield were higher during the dry season (March–September) and lower during the wet season (October–February). The nutritional composition (on a dry matter basis) ranged from 6.97–10.53% Crude Protein (CP), 68.58–73.44% Neutral Detergent Fiber (NDF), 34.69–43.63% Acid Detergent Fibre (ADF), and 9.50–12.61% Acid Detergent Lignin (ADL).

Current situation and implications to enhance rural youth’s access to land: a case study in Hue city

Nguyen Tien Nhat — 2026-03-31

This study examines the barriers to land access and land use among rural youth in Vietnam’s mountainous areas, drawing on interviews with 100 young people, two focus group discussions, and eight key-informant interviews conducted in Long Quang commune, Hue city. The findings indicate that youth face substantial challenges in land access, particularly financial constraints, fragmented landholdings, and limited awareness of opportunities to participate in land policy processes at the grassroots level. Although they acknowledge the importance of land legislation and view recent administrative reforms positively—reflecting the State’s efforts in legal dissemination, but most remain indifferent or disengaged. This results in a persistent gap between policy intentions and practical needs, and constrains the voice of young people in land governance. Building on these insights, the study proposes four key directions: (i) Expanding credit schemes and land-support mechanisms for youth entrepreneurship; (ii) Enhancing youth involvement in resource planning and management; (iii) Strengthening land-law communication through digital platforms; and (iv) Promoting a more transparent, accessible, and youth-friendly administrative system.

Classification of potential soil erosion on agricultural land and mountainous farmer’ perceptions of soil erosion in Hue city

Tung Pham Gia — 2026-03-31

This study was conducted in the mountainous area of the former Phu Loc District, Hue City, to assess potential soil erosion using the Universal Soil Loss Equation (USLE) and to examine local perceptions of this phenomenon based on interview data from 40 agricultural households. The results indicate that potential soil erosion was mainly concentrated in severity classes IV (200–400 t ha⁻¹ yr⁻¹) and V (400–800 t ha⁻¹ yr⁻¹), accounting for 62.76% of the total study area. At the 90% confidence level, a difference was found between Kinh and Co Tu respondents in their ability to correctly identify soil erosion; confusion between soil erosion and landslides was relatively common, particularly among the Co Tu group. However, no statistically significant differences were observed between ethnic groups in identifying the causes and consequences of soil erosion. In terms of gender, no significant difference was found in recognizing the erosion phenomenon itself, whereas statistically significant differences were detected between men and women in identifying its causes and consequences. The study recommends increasing land cover in combination with community communication using accessible language and field-based demonstrations to improve awareness and support the selection of appropriate farming practices.

Research factors affecting the development of wind energy in the context of green transition in Quang Tri province

Nguyen Hoang Khanh Linh — 2026-03-31

The objective of the study was evaluate the influence of factors on the development of wind energy in Quang Tri province. Correlation analysis, exploratory factor analysis (EFA) and regression analysis were employed to process the collected data. The results obtained from 220 survey questionnaires collected from the management officials and the enterprises involved in wind power investment in Quang Tri province revealed six groups of factors affected wind energy development in the context of the green transition, including: (i) Natural and geographical conditions (0.350), (ii) Policy and legal (0.230), (iii) Finance (0.179), (iv) Technology (0.160), (v) Economy (0.123) and (vi) Society and community awareness (0.122). The research results were served as a scientific basis for proposing solutions to accelerate wind energy development in alignment with green growth objectives.

An assessment of land use for tourism development in Lac Duong district, Lam Dong province

Nguyen Hoang Khanh Linh — 2026-03-31

This study presents an assessment of land use for tourism development in Lac Duong District, Lam Dong Province. The research is based on secondary data collection, sociological surveys, and quantitative and qualitative data analysis. The results show that the area of land used for tourism increased during the period 2021–2024, with land within nature reserves accounting for 98.77% of the total tourism land area. This reflects a development orientation toward tourism associated with natural resources. The study also identifies several limitations in land use for tourism, including insufficiently integrated planning, uneven spatial distribution of tourism activities among communes, limited community participation, and increasing environmental pressure. Survey results from three communes (Lat, Da Nhim, and Da Chais) indicate that tourism has influenced local livelihoods, awareness, and agricultural production patterns; however, improvements in income and benefit distribution remain limited, particularly in remote areas. Based on the findings, six groups of solutions are proposed to improve land-use management and support sustainable tourism development in Lac Duong District.

Study on factors affecting real estate investment decisions of residents in Hue city

Nguyen Van Binh — 2026-04-23

This study aims to identify the factors influencing the real estate investment decisions of residents in Hue City. Utilizing secondary data and a primary survey of 150 respondents via questionnaires, the research employed a 5-point Likert scale comprising 27 observed variables across five independent factor groups (legal aspects, location, potential, spirituality, and environment) and three observed variables for the dependent variable (investment decision). The results indicate that the scale possesses high reliability (Cronbach’s Alpha > 0.7), and the data is suitable for Exploratory Factor Analysis (EFA), with a total variance extracted of 61.536%. Multiple linear regression analysis demonstrates that the model is statistically significant (Adjusted $R^2$ = 0.730; Sig. < 0.05), with no evidence of multicollinearity or autocorrelation. All five factors positively impact investment decisions, with the degree of influence in descending order: spirituality (β = 0.295; 25.4%), potential (β = 0.261; 22.5%), environment (β = 0.246; 21.2%), legal aspects (β = 0.244; 21.0%), and location (β = 0.161; 13.9%).
