Abstract
This experiment was carried out to investigate the growth characteristics and seed productivities of orchardgrass "Hwabsung 2 ho" according to seeding times in the NLRI from 2001 to 2002. The experimental design was a randomized block arrangement with three replications. Seed was sown on 10th, 20th, and 30th of Aug. and 10th, 20th, and 30th of Sept. in 2000 and 2001, respectively. Establishment of seedling was worse in seeding of Aug. 10th because of rainfall. Number of panicles per $1\textrm{m}^2$ was numerous in seeding of Aug. 20th and was fewer according as seeding time was later. But panicle did not nearly appear in seeding after Sept. 20th. Seeding of Aug. 20th produced seed yield of 759kg/ha and have most seed yield components. But according as seeding times were later than Aug. 20th, the seed yield was linearly decreased with seed yield components worse.nts worse.
