Abstract
Pioneer 31N27 variety was planted on April 19 at Suwon to determine agronomic and silage traits over time. Ten harvest times was made at intervals of 10 days beginning July 1 to September 20, 2010. Stalk dry matter (DM) content increased with maturity, the highest by 58.5% on September 10 and then decreased (p<0.05). Ear and whole-plant DM content increased linearly with maturity, and whole-plant DM reached by 30% on August 11. Ear DM to whole-plant DM increased with maturity and reached by 63.2% on September 20. Ear DM yield increased with maturity, and stalk, whole-plant and TDN yield were the highest on September 10 and then decreased (p < 0.05). A regression coefficient for DM yield with maturity were 0.57 for stalk, 0.92 for ear, 0.90 for whole-plant and 0.93 for TDN yield.
