This study was conducted to investigate the effect of tall type mixtures and tall+short type mixtures on dry matter yield, botanical composition and quality. The experimental design includes two mixture types: Tall type mixtures(TM); orchardgrass(Potomac) 40+tall fescue(Fawn) 20+Festulolium braunii (Paulita) 10+perennial ryegrass(Reveille) 10+timothy(Climax) 10+red clover(Kenland) 5+alfalfa(Vernal) 5%) and tall+short type mixtures(TSM); orchardgrass(Potomac) 40+tall fescue(Fawn) 20+Kentucky bluegrass(Newport, turf type) 10+redtop(Barricuda, turf type) 10+perennial ryegrass(Palmer III, turf type) 10+red fescue(Flyer II, turf type) 5+white clover(Regal) 5%. The dry matter(DM) yield was higher obtained in TSM than that of TM, but there was no significant difference between TM and TSM. In the chemical composition, there was no significant difference between TM and TSM, but the content of cellulose, lignin were higher in TM than those in TSM(p<0.05). Also, the content of acid detergent fiber which affected dry matter digestibility was higher in TM than that of TSM. The crude protein dry matter yield was not observed significant difference between TM and TSM, but digestible dry matter(DDM) yield was higher in TSM than that of TM. In botanical composition, tall fescue, alfalfa and orchardgrass were highly maintained in TM but white clover, tall fescue and orchardgrass were highly, and redtop, red fescue were continuously maintained in TSM. In this experiment, DM yields and quality of two mixture types were no difference. However, the tall+short type mixtures(TSM) were more effective in enhancing the dry matter digestibility and DDM yield, and in maintaining the various botanical composition.
