In order to reduce the problems from the presence of rye crop residues in maize establishment and yield, and also to improve the growth, productivity and nutritive value of rye(Seca1e cereal L.). an experiment was canied out to determine the variety effect of rye on the forage production system and the eft'ect of seeding and harvesting dates on the production and quality of rye. 'This experiment was conducted at the forage testing field of S.N.U., Suweon, from September 1986 to May 1989. Heading date of an early maturing rye variety, Wintermore. was earlier 10 days than that of a late maturing rye variety, Kodiak. A 15-days delay in the seeding dates of early and late maturing varieties of rye tended to delay the heading dates of the rye varieties for 3 and 4 days, respectively. Dry matter and in vitro digestible dry matter yields were markedly increased with earlier seeding date. Before 20 April, the DM and IVDDM yeilds of an early maturing rye variety, Winterrnore. were higher than those of a late maturing rye variety, Kodiak. However, no such a trend was found between the early and late maturing varieties of rye after 27 April. Less than 35% of ADF was recorded until the harvesting dates of 13 and 27 p r i l for early and late maturing rye varieties, respectively, but less than 46% of NDF was maintained until the harvesting drtte of 13 April for botg varieties. Based on the results obtained from this experiment. it may be concluded that the most desirable forage production from corn-rye double cropping system is to advance the seeding time of rye toward the first 10 days of September as well as harvesting time toward the first heading stage with an early maturing rye variety.
