This experiment was conducted to evaluate the yield performance of forage rape (Brassica napus subsp. oleifera (Metzg.) Sinsk.) in comparison with the common soiling crops, sucH as oats, rye, hybrid ryegrass and turnips in the late fall period. The crops were seeded on August 25, 1982. Plant height, dry matter percentage and forage yield measurements were taken on October 27, 1982. Forage rape and oats were early in maturity and tall with upright stem. Turnips and rye were later to mature than forage rape and oats, but earlier than hybrid ryegrass in the late fall period. The newer forage rape tended to yield more forage than oats, turnips, rye and hybrid ryegrass. Forage rape, oats and Ponda turnips gave the highest dry matter yield, followed by rye and Polybra turnips. Hybrid ryegrass gave the lowest dry matter yield. Rye, hybrid ryegrass and oats showed a higher percentage of dry matter, but forage rape gave a medium percentage. Based on the results of the experiment it appears that cultivars of forage rape recently introduced from the Netherlands have excellent potential as soiling crops in Korea.

This experiment was conducted on the paddy Held of SNU in Suweon, to compare growth characteristics` winter hardiness and forage yield of selected southern and northern types of winter rye (Secale cereale L.), in comparison with Korean native rye during the 1977-81 season. The southern winter ryes were characterized by an upright habit of growth and the Korean native rye exhibited a semi-uplight growth habit, but the northern winter rye showed a prostrate form of growth. Vitagraze, Athens Abruzzi, Wrens Abruzzi and Wonder grazer were earlier in maturity and grew very vigorously and rapidly in the early spring, but the Korean native and northern rye varieties were late in maturity. Vitagraze, Weser and Athens Abruzzi were the best for winter hardiness of all rye varieties, but no differences in winter hardiness were noted between different types of rye with the exception of Rymin in 1978 and Explorer in 1981 which showed the lowest winter survival. Athens Abruzzi in 1978, Athens Abruzzi, Vitagraze and Elbon in 1979 and Wonder grazcr, Vitagraze, Wrens Abruzzi, Athens Abruzzi and Acco WR 811 in 1981, produced significantly more dry matter yield than the northern and Korean native ryes. The southern winter ryes generally produced more forage than the northern and Korean native varieties. Athens Abruzzi, Wrens Abruzzi and Vitagraze were the highest yielding ryes of all rye varieties for the entire seaons.

A field experiment was carried out to determine the effects of cutting height at the third cut and application of N and K₂O after cutting during mid-summer season on the soil temperature, plant height, grass coverage, percentages of grass and legume, yield and grass quality in orchardgrass dominated pasture. With three cutting heights (3, 6 and 9㎝) and 4 fertilizer levels (0, N 50㎏, K₂O 50㎏, and N 50㎏ + K₂O 50㎏ ㏊^(-1)), present experiment was conducted at Livestock Experiment Station, Suwon in 1987. 1. The soil temperature after the third cut was rapidly elevated, and lower value was observed with 9㎝ of cutting height through the regrowth period. Plant height after cutting was remarkably increased with higher stubble height regardless of fertilizer levels. 2. The grass coverage and percentage of grass were increased as stubble height was high, while the influence of fertilizer on those was very little. Application of N and K₂O with lower stubble height significantly increased the percentage of bareland. 3. The yield at the third cut was decreased with higher height. But the regrowth yield was significantly increased as the cutting height was increased regardless of fertilizer levels. Regrowth yield was great at N 50㎏ + K₂O 50㎏ $gt; 0 $gt; K₂O 50㎏, N 50㎏, in that order. However, there were not significantly different on regrowth yield among fertilizer treatment. 4. The contents of crude protein, crude fat, crude ash, P, K and Ca were decreased as stubble height was high, and that of crude fiber was increased at 9 ㎝ cutting height. Also the influence of N and K₂O fertilizer on grass quality was little.

본 연구는 구조방정식모형을 이용하여 자연생태계의 일부분인 기후 네트워크를 구축하여 청보리(Whole crop barley: WCB)의 생산량에 영향을 미치는 기후요인의 인과성을 분석할 목적으로 수행하였다. WCB 데이터셋(n=316)은 사료정보와 기상정보로 이루어졌다. 여기서 생초수량, 건물수량, 재배연도 및 지역을 포함하는 사료정보는 다양한 신품종재배실험(1993-2012)으로부터 수집하였다. 기상정보는 일평균온도, 강수 및 일조시간을 포함하며 기상청의 기상정보시스템으로부터 수집하였다. 기상 변수는 파종일부터 수확일까지 기간을 계절(가을, 겨울 및 이듬해봄)로 구분한 생육기간, 누적온도, 강수 및 일조시간이었다. 생산량에 영향을 미치는 기후의 인과성 네트워크는 구조방정식에 의해 모델로 만들었다. 그 결과, 세가지 특징으로 가을과 이듬해봄 간의 종단효과, WCB 생산량에 대한 직접효과, 그리고 온도를 통한 강수의 간접효과가 뚜렷하게 나타났다. WCB 생산량에 대한 중요성은 이듬해봄 온도(0.45), 가을온도(0.35), 월동(-0.16) 및 이듬해봄 강수(0.04) 순으로 나타났다. 그러므로 본 연구를 통해 온도, 생장일수, 강수 및 일조를 포함한 기후 네트워크에서 다른 기후요인들이 최종경로인 이듬해 봄의 온도와 생장일수를 통해 WCB 생산량에 간접적으로 영향을 미친다는 결론을 내렸다. This study aimed to analyze causality of climatic factors that affecting the yield of whole crop barley (WCB) by constructing a network within the natural ecosystem via the structural equation model. The WCB dataset (n=316) consisted of data on the forage information and climatic information. The forage information was collected from numerous experimental reports from New Cultivars of Winter Crops (1993-2012) and included details of fresh and dry matter yield, and the year and location of cultivation. The climatic information included details of the daily mean temperature, precipitation, and sunshine duration from the weather information system of the Korea Meteorological Administration. The variables were growing days, accumulated temperature, precipitation, and sunshine duration in the season for the period of seeding to harvesting. The data was collected over 3 consecutive seasons―autumn, winter, and the following spring. We created a causality network depicting the effect of climatic factors on production by structural equation modeling. The results highlight: (i) the differences in the longitudinal effects between autumn and next spring, (ii) the factors that directly affect WCB production, and (iii) the indirect effects by certain factors, via two or more paths. For instance, the indirect effect of precipitation on WCB production in the following spring season via its effect on temperature was remarkable. Based on absolute values, the importance of WCB production in decreasing order was: the following spring temperature (0.45), autumn temperature (0.35), wintering (-0.16), and following spring precipitation (0.04). Therefore, we conclude that other climatic factors indirectly affect production through the final pathway, temperature and growing days in the next spring, in the climate-production network for WCB including temperature, growing days, precipitation and sunshine duration.

This study aimed to determine the trend in dry matter yield (DMY) of a new sorghum-sudangrass hybrid (SSH) in the central inland regions of Korea. The metadata (n=388) were collected from various reports of the experiments examining the adaptability of this new variety conducted by the Rural Development Administration (1988-2013). To determine the trend, the parameters of autoregressive (AR) and moving average (MA) were estimated from correlogram of Autocorrelation function (ACF) and partial ACF (PACF) using time series modeling. The results showed that the trend increased slightly year by year. Furthermore, ARIMA (1, 1, 0) was found to be the optimal model to describe the historical trend. This means that the trend in the DMY of the SSH was associated with changes over the past two years but not with changes from three years ago. Although climatic variables, such as temperature, precipitation, and sunshine were also considered as environmental factors for the annual trends, no clear association was observed between DMY and climates. Therefore, more precise processing and detailed definition of climate considering specific growth stages are required to validate this association. In particular, research on the impact of heavy rainfall and typhoons, which are expected to cause damage in the short term, on DMY trends is ongoing, and the model confirmed in this study is expected to play an important role in studying this aspect. Furthermore, we plan to add the environmental factors such as soil and cultivation management as well as climate to our future studies.

In order to select higher yielding forage suited for silage, the yield performance and associated characteristics of 23 introduced sorghum-sudangrass hybrids (Sorghum bicolor (L.) Moench) have been evaluated at the Experimental Livestock Farm, COA, SNU, Suweon in 1979 and 1981. The results obtained are summarized as follows: 1. NK 367, Pioneer 931 and FS 24 gave significant highest forage yields than the control variety, Suweon 19 hybrid corn (P $lt; 0.05). There were no significant differences in forage yield between FS 4, FS 25A, T-E TDN, X 4318, Silo Milo and Suweon 19 hybrid corn, but these sorghum-sudangrass hybrids were the better forage producers. 2. Average grain percentages to the total forage yield of various hybrids tested ranged from 9.8% for FS 24 to 44.8% for FS 351 except NK 367. The grain percentages of FS 351 and Silo Milo were the highest and similar to that of Suweon 19 hybrid corn where 43.5% grain was obtained. 3. FS 251, NK 326 and FS lA headed and flowered early than other hybrids, while Pioneer 931, T-E TDN, X 4318 and Pioneer 944 showed later. NK 367 was the latest hybrid in maturity. 4. NK 367 and Pioneer 931 were found to be as tall type hybrids, while FS 251 and FS 351 appeared short types. Although no diseases and lodging were found in most hybrids, T-E Goldmaker was susceptible to leaf disease and SS IV gave severe lodging during the growing season. 5. The results indicated that Silo Milo, X 4318, FS 25A and T-E Silomaker have high silage yield potential with moderately high grain, and NK 367, Pioneer 931, FS 24, T-E TDN and FS 4 also have high yield potential with relatively low grain.
