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

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.
