TAILIEUCHUNG - Initial assessment on growth and yield of some grass varieties grown in the northwestern mountainous region

The study was carried out to test the viability, growth and yield of 05 grass varieties including Guatemala, Ghine TD58, Mulato 2, VA06 and Stylo in both highland and lower land of the Northwestern mountainous area. These forages were grown in experimental plots with 3 replicates for each variety. | Mai Anh Khoa và Đtg Tạp chí KHOA HỌC & CÔNG NGHỆ 115(01): 27 - 32 INITIAL ASSESSMENT ON GROWTH AND YIELD OF SOME GRASS VARIETIES GROWN IN THE NORTHWESTERN MOUNTAINOUS REGION Mai Anh Khoa1*, Nguyen Hung Quang2, Phan Dinh Tham2, Nguyễn Duy Hoan3, Stephen Ives4 1 Thai Nguyen University, 2College of Agriculture and Forestry – TNU, Learning Resourse Center – TNU3, 4Tasmania University, Australia SUMMARY The study was carried out to test the viability, growth and yield of 05 grass varieties including Guatemala, Ghine TD58, Mulato 2, VA06 and Stylo in both highland and lower land of the Northwestern mountainous area. These forages were grown in experimental plots with 3 replicates for each variety. The investigation results in the first year of plantation showed that all 5 varieties adapted perfectly with the natural conditions of the studied area; Showed to have good growth and development; and yielded range from 10-70 tons/ha/harvest. Especially, VA06 and Guatemala grass varieties had the highest capability of growth and yield. They can be planted widely in massive production in the study areas. Key words: Guatemala grass; Mulato 2; VA06 grass; Ghine grass, Stylo grass; Growth, yield. INTRODUCTION* According to the General Statistics Office, the number of cattle in the northern mountainous provinces has been decreasing continuously (buffalo fell by %, cow lessened by % from 2008 to 2011) this declination was due to a number of causative factors such as adverse weather conditions and natural forage source reduction due to unsuitable plantation and forest management method. Whereas, the amount of planted grass and forage trees in addition to agricultural byproducts only met % of the total forage requirements of cattle. Thus, lack of forage sources, especially for raising ruminants is an urgent problem and is one of the reasons why livestock husbandry has not developed in accordance with its potentials.
