This study amied to determine the effect of species and seed mixture on productivity, botanical composition and forage quality in middle mountainous region (Geosan) pasture. Total seven experimental pastures (T1 : Orchardgrass, T2 : Timothy, T3 : Tall fescue, T4 : Perennial ryegrass, T5 : Kentucky bluegrass, T6 : Timothy + Orchardgrass + Tall fescue + Alfalfa, T7 : Timothy + Orchardgrass + Kentucky bluegrass + White clover) were established in autumn, 2014 and evaluated for productivity and agronomic characteristics for 2015. Plant heigh was high in Orchardgrass and Perennial ryegrass pasture. Dry matter (DM) content was high in Kentucky bluegrass. Botanical composition in $1^{st}$ harvest was high in shrub, but the grass composition was high in $2^{nd}$ and $3^{rd}$ harvest. Fresh and DM yield were higher in Orchardgrass and Perennial ryegrass (p<0.05); whreras, Kentucky bluegrass was the lowest. In seed mixture pasture, yields of T6 plot (Tall fescue) were higher than those of T7 (Kentucky bluegrass). Average CP (crude protein) content of $2^{nd}$ and $3^{rd}$ cutting time was 16.91 and 14.79%, respectively and Kentucky blue grass was the highest in $3^{rd}$ cutting time by 17.57%. IVDMD (in vitro dry matter digestibility) showed low in $1^{st}$ cutting and Kentucky bluegrass was the lowest in every cutting time. TDN (total digestible nutrient) content was the highest in $3^{rd}$ cutting and the lowest in $1^{st}$ cutting. These results indicated that Orchardgrass, Perennial ryegrass and T6 are recommendable for productivity and Timothy, Perennial ryegrass and T7 are recommendable for forage quality.
