This experiment was conducted to investigate the effects of mixed application of earthworm cast and N-fertilizer on dry matter(DM) yield in orchardgrass(Dactylis glomerate L.). Experimental plot were designed by a randomized block design with 3 replications of six different treatments-Control(0:0), 100% earthworm cast(0:100), 3 levels of mixed application(25:75:, 50:50, 75:25) of earthworm cast and N-fertilizer, and 100% N-fertilizer(100:0)based on content (%) of nitrogen. The experiment was carried out from March to October, 1993, on the forage experimental field of Kon-Kuk Univ. in Seoul. The results obtained are summarized as follows: 1. Annual dry matter yield was significantly increased according to increasing of N-fertilizer 2. Dry matter yield for each treatment as cutting time was passing was decreased. However, dry matter yield was slightly increased at 75%, 50%, and 25% mixed application of earthworm cast at the third cutting time than the second cutting time(p<0.05). 3. concerning each treatment per cutting time, dry matter yield was higher at 100% N fertilizer than the other treatments at the first, second, and fourth cutting time except the third cutting time only(p<0.05). And according to decreasing of mixing ratio of N fertilizer, dry matter yield was decreased, too. 4. Dry matter yield of 100% earthworm cast was significantly higher than control at the fourth cutting time(p<0.05).
