An experiment was conducted during the 3-year period 1967-1969 at the Livestock Experiment. Station, Sunghwan, to determine the effect of different seeding rates of Orchardgrass (Dactylic glomerata) and Ladino clover (Trifolium repens L. $quot;Yar. Ladino$quot;) on the total dry matter yield and botanical composition of pasture mixtures. The results are as follows: 1. High seeding rates of 2㎏ to 3㎏ of grass with 0.3㎏ to 0.5㎏ of clover per 10a reduced the percentage establishment of viable seed sown. However no differences were found in tillers per plant between seeding rates in grass and clover. 2. Botanical compositions of grass and clover 50 days after sowing were closely related to the seeding rates. For 2-years following seeding, however, the seeding rates of grass and clover had no any appreciable effect on the botanical composition of pasture species. 3. Different seeding rates of grass and clover had no significant influence on the total air dry matter yield of pasture mixtures in subsequent years. As the results of the experiment, a seeding rate of 1㎏ of orchardgrass with 0.1㎏ of ladino clover per 10a would be the most reasonable basic seed mixture under our conditions.
