This study was performed out to investigate the influence of the mixed application of chemical fertilizer (CF) and liquid swine manure (LSM) on the growth characteristics, dry matter yield, amino acids, minerals, and free sugars in cultivating silage corn on paddy soils. The field experiment was designed in a randomized block design of 3 repetitions with CF 100% treatment (C), CF 70% + LSM 30% treatment (T1), CF 50% + LSM 50% treatment (T2), CF 30% + LSM 70% treatment (T3), and LSM 100% treatment (T4). At this time, the application of LSM was based solely on the nitrogen. Ear length, ear circle, stem diameter, and stem hardness of the silage corn did not show significant differences between treatments. Fresh yield, dry matter yield and TDN yield were highest in T3, whereas the lowest in C treatment (p<0.05). Crude protein, crude fat, and crude ash content were significantly higher in T1, C, and T4 treatment, respectively (p<0.05). However, NDF, ADF and crude fiber content did not show significant difference between treatments. The total mineral content decreased significantly (p<0.05) as the LSM application rate increased. Total composition amino acid content was higher in the order of T1 > T2 > C > T4 > T3 treatment (p<0.05). Free sugar content was higher in the order of T1 > T3 > T4 > T2 > C treatment (p<0.05). Based on the above results, suggests that the mixed application of chemical fertilizer 30~50% and LSM 50~70% (T2 and T3) is the most effective, considering the yield performance and the content of sugar degree and free sugar affecting silage.

In order to identify the growth characterization, the yield and chemical composition of Jeju barnyard grass (Echinochloa crusgalli var. fiurnentacea(Roxb) Wight) based on seeding date in Jeju region, seeding carried out the 10-day intervals from March 27 to September 30 in 2000, respectively. Plant height was 143.2 cm, showing the highest on seeding date, April 6 among that of any other seeding date. On the other hand, those of early and late seeding gradually decrease. Plant height was 119.2 an in May 16 seeding. The results of stem diameter, number of withering leaves, number of leaves and fresh weight per plant were similar to those of the plant heights. The yield of fresh, dry matter forage, crude protein and TDN found the highest on April 6 seeding, 63.5 MT/ha, 13.9 MTha, 1.1 MT/ha, and 7.6 MT/ha, respectively. In early and late seeding, the yield was gradually decreased. In seeding May 16, the yield found .38.2 MTIha in fresh forage, 6.2 MTha in dry matter forage, 0.7 MT/ha in crude protein and 3.7 MTha in TDN, respectively. According to delaying the seeding date, March 27 to May 16, the contents of crude protein (from 7.9 to 10.8%), ether extract (from 4.6 to 6.0%), nitrogen free extract (from 45.1 to 46.5%), and TDN (from 54.2 to 60.8%) were gradually increased, respectively. On the other hand, those of crude fiber (from 28.9 to 25.6%) and crud ash (from 13.5 to 11.2%) were decreased. These results showed that April 6 was the optimum seeding date with the sole object of feed production of Jeju barnyard grass under the environmental condition like as atmospheric phenomena and soil in Jeju region.

The objectives were to assess the use of near-infrared reflectance spectroscopy (NIRS) as a tool for estimating nutrient compositions of corn kernel, and to apply an NIRS-based indium gallium arsenide array detector to the system for collecting spectra and analyzing calibration equations using equipments designed for field application. Partial Least Squares Regression (PLSR) was employed to develop calibration equations based on representative data sets. The kennard-stone algorithm was applied to induce a calibration set and a validation set. As a result, the method for structuring a calibration set significantly affected prediction accuracy. The prediction of chemical composition of corn kernel resulted in the following (kennard-stone algorithm: relative) moisture ($R^2=0.82$, RMSEP=0.183), crude protein ($R^2=0.80$, RMSEP=0.142), crude fat ($R^2=0.84$, RMSEP=0.098), crude fiber ($R^2=0.74$, RMSEP=0.098), and crude ash ($R^2=0.81$, RMSEP=0.048). Result of this experiment showed the potential of NIRS to predict the chemical composition of corn kernel.

To evaluate the effect of Hydrangea serrata Seringe extract on kakdoogi(Korean radish kimchi), the kakdoogi was prepared, after supplementation, with Hydrangea serrata Seringe extract(0, 1.25, 2.5 and 5%(v/w)). The quality characteristics of the kakdoogi were investigated during 7 days of fermentation at $20^{\circ}C$. The proximate components of the Hydrangea serrata Seringe leaves were 3.48% crude protein, 6.45% crude lipid, 7.98% crude fiber and 9.32% crude ash. The pH values in the samples with the extract were higher than that of both the control group and the sugar group. The total acidity levels in the sugar group was higher than that of other groups. The sugar group showed higher L value(lightness) than that of kakdoogi fermented with the extract. A value(redness) and B value(yellowness) of the supplemented kakdoogi was lower than that of the control and the sugar group on day 7. The hardness of samples with the extract was higher than that of the sugar group. And the hardness of the groups with the extract was not reduced during the fermentation period. The control group showed higher salinity than the other groups by day 4. The samples with the extract were sweeter than the control group on day 0 then the difference disappeared after day 2. Sourness of all the groups increased during the fermentation period. However the extract did not affect the hardness or overall acceptability of the kakdoogi during fermentation.

To find the optimum proportion of Hydrangea serrata Seringe(HSS) powder, rice cakes were prepared with different quantities of Hydrangea serrata Seringe powder instead of sugar. Technical and sensory examinations were then conducted. The proximate components of the HSS leaves were 3.48% crude protein, 6.45% crude lipid, 7.98% crude fiber and 9.32% crude ash. The pH values of samples which replaced 25%, 50%, 75% and 100% of sugar with the HSS powder were significantly decreased(p<0.05). The groups with HSS powder showed a lower L value(lightness) and a value(redness) than that of the control group. The B value(yellowness) of the Sulgidduk containing the HSS powder was higher than that of the control group. The hardness of HS2 and HS3 was increased by the addition of the HSS powder. The adhesiveness of Sulgidduk groups with the HSS powder was higher than that of the control group. Springiness was not changed by adding the HSS powder. The cohesiveness of the Sulgidduk was significantly reduced by adding the HSS powder(p<0.001). The groups with no sugar showed the highest gumminess and chewiness. The added HSS powder caused both a darker color and a stronger odor, but the sweetness of the Sulgidduk which replaced the sugar with the HSS powder was decreased compared to the control group. The moisture content and the hardness was not affected by the addition of the HSS powder. The preference of color and taste was not changed by adding the HSS powder. The preference of flavor of the Sulgidduk with the HSS powder showed higher than that of the control. Overall acceptability of the Sulgidduk did not show any significant differences. As a result, Sulgidduk can be replaced 25% and 50% of sugar with the Hydrangea serrata Seringe powder.

본 연구에서는 솔잎분말을 첨가하여 기능성식빵을 제조하기 위한 반죽의 품질특성을 조사하였다. 일반 성분측정 결과 생 솔잎은 수분 58.1%, 조단백질 4.5%, 조지방 3.9%, 조회분 0.9%, 식이섬유량 9.3%로 나타났다. 반죽의 pH 측정 결파 대조구의 pH는 5.9, 솔잎분말 $1{\sim}3%$ 첨가시에는 $5.8{\sim}5.5$ 범위로 나타났다. 반죽의 호화도는 솔잎분말 첨가량이 증가함에 따라 호화 개시 온도는 증가하였고 최고 점도는 감소하였다. 반죽의 falling number는 솔잎분말 첨가량이 증가할수록 낮아졌다. Farinograph, alveograph에 의한 분석결과 수분흡수율의 경우 솔잎분말 첨가량이 증가할수록 반죽 안정도는 증가하였고, 반죽 발전시간은 감소하였다. Alveograph은 최대압력을 나타내는 P값은 솔잎분말의 첨가량이 증가할수록 낮아졌고 부피와 신장성도 솔잎의 첨가량이 증가할수록 감소하였다. 반죽 발효팽창력 또한 솔잎분말의 첨가량이 증가할수록 감소하였다. 솔잎분말의 첨가량이 증가할수록 제빵 반죽의 물리성이 떨어진다는 결과를 얻을 수 있었다.
