Effect of Mixed Pasture Using Domestic Varieties Orchardgrass ‘Kodione’ and Tall fescue ‘Purumi’ on Forage Yields and Botanical Composition in Middle Region of Korea
pp.89-97
This study was carried out to determine the effect of mixed pasture using domestic varieties orchardgrass ‘Kodione’ and tall fescue ‘Purumi’ on forage yields and botanical composition from 2013 to 2015 in middle region of Korea. The following mixed pastures were used in this study: treatment A (orchardgrass oriented mixture with imported varieties), treatment B (orchardgrass oriented mixture), treatment C (orchardgrass and tall fescue oriented mixture), treatment D (tall fescue oriented mixture), treatment E (tall fescue oriented mixture without orchardgrass), treatment F (only orchardgrass), and treatment G (only tall fescue). In botanical compositions at last cutting time in 2015, treatment A had orchardgrass at 7.1%, tall fescue at 47.9%, kentucky bluegrass at 15.2% and white clover at 25%. Meanwhile, treatment B had orchardgrass at 25.9%, tall fescue at 47.0%, kentucky bluegrass at 4.9% and white clover at 18.3%. Consequentially, in botanical composition from 2014 to 2015, treatment A was changed more compare to other treatments B, C, D and E. The average of dry matter (DM) yield for 2 years of treatment E (18,369 kg/ha) was the highest among the seven treatments, but there was no significant difference among other treatments except treatment A (p>0.05). The crude protein (CP) and in vitro dry matter digestibility (IVDMD) of treatment A were 14.5% and 74.8%, and treatment E were 14.1% and 73.0%, respectively. The content of neutral detergent fiber (NDF) and acid detergent fiber (ADF) were lower in treatment E and A than other treatments, and treatment E showed high content of total digestible nutrient (TDN). Therefore, tall fescue oriented mixture using domestic tall fescue variety Purumi had good forage productivity, quality and botanical composition in middle region of Korea for the establishment of grassland.
