The experiment consisted of 3 different treatments (NT) respectively to 3 different cutting heights at the first harvesting, that were NT1: 30cm
NT2: 45cm
NT3: 60cm measured from ground level. Each treatment was carried out in an area of 24m² with 5 replicates, the design was in randomize block. The other factors such as density, fertilizer, cutting intervals ... were similar among treatments. Results showed that, dry matter and crude protein yields were higher in treatments with higher cutting levels
dry matter yield of NT1, NT2 and NT3 were 8.172, 8.975 and 9.282 tons/ha/year. That of crude protein was 2.798, 3.073 and 3.178 tons/ha/year. Based on dry matter and crude protein yields and statistical analysis data, it was concluded that for the first harvesting, the cutting height should be 40-60cm, the most suitable cutting height was 60cm.
