Abstract

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).
