1. Dry matter intake was significantly increased above the 30% red clover plant composition (p<0.05) as compared with 100% orchardgrass plant composition. However, there was a significant positive correlation (p<0.05) between the content of CP and dry matter intake, and was a significant negative correlation (p<0.05) between the content of NDF and dry matter intake. 2. Dry matter digestibility was significantly increased with the increase of red clover plant composition as compared with 100% orchardgrass plant composition (p<0.05). Digestible dry matter intake was significantly increased above the 20% red clover plant composition (p<0.05) as compared with 100% orchardgrass plant composition. However, there was a significant positive correlation (p<0.05) between the content of CP and digestible dry matter intake, and was a significant negative correlation (p<0.01) between the content of NDF and digestible dry matter intake. 3. Preference of herbage samples tended to markedly increased with the increase of red clover plant composition.

The effects of different fertilizer management on herbage production and botanical composition were determined. Field experiments were conducted during 1991 - 1993 on sandy loam soil at Allgiu south western Germany under variabling fertilizer management; cattle slurry, NPK, PK chemical fertilizer management and zero fertilization. The dry matter yield of forage was the highest in the plot of mineral fertilizer and lowest in the plot of without fertilization. The dry matter yield of P-K application was higher by 1.2 ton than that of without fertilization. The content of crude protein, crude fibre, digestible dry matter yield, net energy and nitrogen content of plants was not significantly different among different fertilizer management. N uptake of plants was in the order NPK chemical fertilizer (347kg N/ha) > cattle slurry (337kg N/ha) > P-K chemical fertilizer (325kg N/ha) > without fertilization (3 15kg N/ha).

This experiment was conducted to establish the cultural method of triticale(Triticum Secalotriticum Saratoviense Meister) as a whole crop silage by evaluating the effect of seeding date and nitrogen fertilization rate on forage yields and feeding value. Heading date, flowering date, and the dough stage of development came significantly earlier as triticale was seeded earlier. Soilage, dry matter yields and percent dry matter significantly varied with seeding dates and crude ash, NFE and TDN. However, TDN yield was significantly reduced by delayed seeding. Macromineral contents were not affected by seeding date. Soilage, dry matter yield, and percent dry matter significantly increased as nitrogen fertilization rate increased. The contents of crude protein, crude fat, crude ash, NFE, TDN and TDN yield also significantly increased. In contrast, crude fiber content of triticale decreased with increasing N fertilization rate.

The experiment was conducted to evaluate the effect of the different seeding date on the dry matter yield and chemical composition of oat for forage. The crops wrc sccdcd on August 3l(lirst). Scptember IO(second). and September 20(third seeding date) and were taken on November 24, 1991. The results are summarized as follows : 1. The plant heights were 68, 54 and 40 cm at first, second, and third seeding date, respetively. 2. Dry matter (DM) content decreased with delaying seeding date from first to third seeding date. DM varied from 18.6 to 14.9 %. 3. Leaf weight ratio increased with delaying seeding date from first to third seeding date, varied from 51 to 67 %, but stems decreased from 49 to 33 %. 4. The dry matter yields per ha decreased with delaying seeding date: it was 5.670. 3.960 and 2.310kg at first, second and third seeding date.

To determine as optimal sowing time of forage rape in spring time in southern areas of Korea, forage rape cv. Velox, the highest yielding variety among introduced varieties of forage rape, was grown under five different sowing times. Yield components such as plant length, number of branches and number of leaves etc. were higher at the sowing time of Mar. 15 and Mar. 25. The plants sown at Mar. 15 and Mar. 25 also showed highest fresh and dry matter yield. When plants were grown under later sowing time, they showed higher values in content of crude protein and lower values in contents of crude fiber such as Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), cellulose and lignin. There was no relationship between variation of In Vitro Dry matter Digestibility (IVDMD) and sowing time. The plants sown at Mar. 15 and Mar. 25 showed highest digestible dry matter yields.

To determine optimal plant density of forage rye in southern areas of Korea, forage rye cv. Paldanghomil, the highest yielding variety among experimental varieties of forage rye, was grown under five different plant density. Yield components such as plant height, and number of leaves were highest at the broad casting. Plants sown at broadcasting also showed highest fresh and dry matter yield. When plants were grown of the broad casting, they showed higher values in content of crude protein and lower values in contents of crude fiber such as neutral detergent fiber(NDF), acid detergent fiber(ADF), cellulose and lignin. There was no relationship between variation of in vitro dry matter digestibility(IVDMD) and plant density. Plants sown at the broad casting showed highest digestible dry matter yields.

Many farmers apply cattle slurry on grassland, often in excess of crop N requirements, resulting in groundwater contamination. Our research objective was the development of grassland management systems that reduce undesirable sideeffects on other compartment of the ecosystem. Field experiment was conducted during 1991~1993 on sandy loam soil at AllgZiu south western Germany. Different sets of conditions were tested such as : zero fertilization, reduced sluny application$(l20kg N ha^{-1}yr^{-1})$, intensive sluny application(conventional sluny application, $240kg N ha^{-1}yr^{-1}$). The plots of the reduced slurry application had no significant effect on dry matter yields, digestible dry matter and net energy of herbage. Dry matter yield of zero fertilization was significantly lower than that of usual slurry application, however the content of Ca and Mg in herbage tended to increase. We conclude that reduced sluny application can be applied on grassland without adverse effects on dry matter production and quality of herbage.

본 연구는 중부 내륙지방에서 벼 수확 후 호밀, 귀리, 트리티케일 및 이탈리안 라이그라스를 파종하여 생육특성, 수량성 및 사료가치를 검정한 다음 벼 수확 후 재배에 유리한 월동 사료작물을 선발하기 위하여 실시하였다. 실험설계는 4초종(호밀, 귀리, 트리티케일 그리고 이탈리안 라이그라스)으로 하고, 품종은 각각 마톤, 동한, 신영 및 코윈어리로 난괴법 3반복 실시하였다. 파종일은 10월 24일(벼 수확 후)에 하였으며, 수확은 이듬해 5월 23일에 실시하였다. 건물수량 및 TDN 수량은 호밀이 가장 높게 나타난 반면 귀리가 가장 낮게 나타났다(p<0.05). 조단백질 및 조지방 함량은 이탈리안 라이그라스가 다른 초종 보다 유의적으로 높게 나타났다(p<0.05). 조회분 및 ADF함량은 월동 사료작물 간에 유의적인 차이가 없었다(p<0.05). NDF 함량은 호밀 > 트리티케일 > 귀리 > 이탈리안 라이그라스 순으로 높게 나타났다(p<0.05). 그리고 TDN 함량은 이탈리안 라이그라스 > 귀리 > 트리티케일 > 호밀 순으로 나타났다(p<0.05). 총 구성 아미노산 함량은 단백질함량이 높았던 작물 순(이탈리안 라이그라스 > 귀리 > 트리티케일 > 호밀)으로 높게 나타났다(p<0.05). 총 무기물 함량은 호밀 > 트리티케일 > 귀리 > 이탈리안 라이그라스 순으로 나타났다. 유리당 함량은 귀리 > 이탈리안 라이그라스 > 트리티케일 > 호밀 순으로 나타났다. 이상의 결과를 종합해 보면 이탈리안 라이그라스와 귀리는 조단백질, TDN, 구성 아미노산, 유리당 함량이 높아 사료가치는 매우 양호하였으나 파종적기를 벗어난 늦은 파종으로 인하여 건물수량이 낮았다. 그리고 호밀과 트리티케일은 사료가치는 떨어지지 만 높은 수량을 확보(건물수량 및 TDN 수량)할 수 있는 장점이 있었다. 따라서 중부 내륙지방에서 벼 수확 후 다음 해에 모심기 전까지 논토양을 이용하기 적합한 월동 사료작물 재배는 호밀과 트리티케일이 유리할 것으로 판단된다.

This study was wnducte to investigate the effects of treatment level and seasons of sluny hm bovine feces on the productivity of rye, N efficiency and improvement of soil fertility under the Korean climate condition. The results obtained fiom this study summarized as follows ; 1. The highest dry matter yield of rye was obtained in the partial fertilization of sluny in spring or autumn. There is no differences of dry matter yield between spring and autumn application. 2. With increasing the amount of slurry-N, the dry matter yield of rye was signigicantly increased up to 100Kg sluny Nha. As the level of slurry-N rises above about 100Kg N/ha, the maximal yield of dry matter was unchanged or declined. 3. As the level of sluny fertilization rises, the crude protein content of rye increases significantly. However the contents of crude protein was less affected by the application seasons. 4. The amount of nitrogen which produced 6om rye is dependent upon the level of slurry-N. The highest nitrogen yield of rye was obtained by the partial fertilization of sluny-N. 5. The season or amount of slurry treatments did not affect the organic matter content in soil. N-content in soil was the lowest by the partial fertilization of slurry in spring or autumn. However, N-content was increased with the higher level of sluny-N.
