Abstract

This study was conducted to investigate the effect of the seeding and harvesting dates on the growth characteristics, dry matter yield and quality of com for silage in alpine area(altitude 800m a.s.l.) of National Livestock Research Institute from 2001 to 2002. The experiment was arranged in a split plot design with three replications. Main plots consisted of three seeding dates, 10 May, 20 May and 30 May. Sub plots consisted of harvesting dates, 15 September, 25 September and 5 October. Tassel height of com was decreased with seeding dates, 30 May, 10 May and 20 May in order, and harvesting date of 5 October was apt to be high. Ear height of com was decreased with seeding dates, 20 May, 30 May, and 10 May in order, and harvesting date of 15 September was the lowest of all treatments. Ear rate of com was decreased with late seeding dates, and it was the highest with harvesting date of 5 October. Dry matter yield was decreased with late seeding dates(P<0.05), and it was increased with late harvesting regardless of seeding dates(P<0.05). Crude protein content of com stover was increased with late seeding dates, and that of com ear was the highest with seeding date of 20 May. And crude protein contents of com stover and ear were the highest with harvesting date of 15 September. NDF contents of com stover and ear were the highest with seeding date of 10 May and 20 May, respectively, and NDF content of com stover was the highest with seeding date of 10 May and there was no difference among treatments in NDF content of ear. ADF content of com stover was 42.1 to 42.6% regardless of seeding dates, and that of com ear was the highest with seeding date of 30 May. ADF content of com stover and ear was increased with early harvesting date excepting for harvesting date of 20 May. These results indicate that 20 May and 25 September would be the optimum seeding date and harvesting date, respectively, for dry matter yield and nutritive value of silage com in alpine area.
