  • This experiment was canied out to study the effects of seeding and harvesting dates on the growth of early and late maturing rye(Seca1e cereale L.) varieties at the forage testing field of S.N.U., Suweon, from September 1986 to May 1989. Leaf and tiller numbers of rye per plant were increased with earlier seeding date, but no difference in the tiller numbers was found between harvesting dates of early and late maturing rye varieties. Tiller dry weight of an early maturing rye veriety, Wintermore was higher than that of a late maturing rye variety, Kodiak when sown as early as September. Maximun leaf area index(LA1) and leaf area index duration(LA1D) were achieved with earlier seeding and early maturing rye varieties. A higher correlation between the maximum LA1 or LAID and dry matter accumulation of rye varieties was observed in this experiment.

  • This experiment was conducted to measure nutrient digestibility and performance in broiler chicks fed diets based on normal and low viscosity rye or barley fed with and without enzyme (pentosanase and $\beta$-glucanase) during a 17 day growth trial. A total of 150 one-day old, male broiler chicks (5 birds per pen and 5 pens per treatment) were randomly assigned to one of six dietary treatments in a $3{\times}3$ factorial design experiment (3 cereals${\times}$2 enzyme levels). Digestibility coefficients were determined using chromic oxide. Digestibility coefficients for dry matter and crude protein were significantly (p=0.0001) higher for the barley-based diets than for any of the rye-based diets. Digestibility coefficients for gross energy did not differ (p>0.05) due to cereal grain. There were no differences in the digestibility coefficients for dry matter and gross energy between chicks fed normal and low viscosity rye. However, the digestibility coefficient for crude protein was higher (p=0.01) for the low viscosity rye compared with the normal viscosity rye. Addition of enzyme to the diet significantly (p=0.0001) increased digestibility coefficients for dry matter, crude protein and energy. There were no significant differences in weight gain, feed intake or feed conversion between birds fed barley or rye or between birds fed normal or low viscosity rye. Enzyme supplementation significantly improved (p=0.0001) weight gain, intake and feed conversion. The overall results of this experiment indicate that unsupplemented barley and rye do not support adequate growth rates in poultry. Enzyme supplementation dramatically improved broiler performance. In addition, genetic selection to reduce the viscosity of rye had only a modest effect on the nutritive value of rye for broilers.

  • To identify the effects of straw mulching on soil physicochemical properties in reclaimed saline soil, field experiment was conducted for 3 years (2010~2012) in Saemangeum reclaimed land. Soil series of the experimental field was Munpo and soil texture was fine sandy loam. The experiment was conducted at a field with EC of $2.4dS\;m^{-1}$ (field I) and the other field with EC of $5.6dS\;m^{-1}$ (field II). Each experimental field was treated with rye straw incorporation, mulching with rye straw and control. In 2010 rye straw produced from other field was used for the experiment and in 2011~2012 rye straw cultivated at the same experimental field was used. After rye straw application, soybean was cultivated. After 3 years field experiment, by rye straw incorporation, soil salinity decreased from $2.4dS\;m^{-1}$ to $0.6dS\;m^{-1}$ at field I but increased from $5.6dS\;m^{-1}$ to $7.6dS\;m^{-1}$ at field II. By mulching with rye straw soil salinity decreased from $2.4dS\;m^{-1}$ to $0.5dS\;m^{-1}$ at field I and also decreased from $5.6dS\;m^{-1}$ to $0.5dS\;m^{-1}$ at field II. By rye straw incorporation and mulching soil organic matter increased from $2g\;kg^{-1}$ to $4g\;kg^{-1}$. At field I yields of soybean were similar between rye straw incorporation and mulching but at field II yield of soybean increased apparently by mulching with rye straw compared to rye straw incorporation and control.

  • This study will attempt to show how marriage ceremonies in Korea have reflected marriage custom influences from science and industrialization the study focuses on changes in traditional features. As a result of science and industrialization, the social patterns of Korean marriages have considerably changed, due to the impact of western values. There are three stages of the Korean marriage ceremony: before the ceremony (Sun-rye), the ceremony (Bon-rye) and after the ceremony (Hu-rye). The research examined how these marriage customs were influenced by science and industrialization. The instruments were 750 questionnaires, analyzed through data processing and personal interviews with 25 married women. The data were analyzed by making use of the SPSS program using frequency analysis and $x^2$-test. The results suggested that, since 1960, Korean marriage ceremonies mainly conformed to the marriage customs of traditional society. Since 1970, traditional customs of the before the ceremony (Sun-rye) process have been, in large part, eliminated. The ceremony (Bon-rye) process has been changed to western style, and the after the ceremony (Hu-rye) process has been altered to some degree.

  • This study was conducted to investigate the effect of cattle manure application on productivity, feed value, and stock carrying capacity of forage crops in upland and paddy fields at Gang-Wondo area. In the result, dry matter yield of sorghum ${\times}$ sudangrass hybrids obtained was 15.12 ton/ha at the level of 150kg N/ha of composted cattle manure. Significantly highest values of crude protein and total digestible nutrients (TDN) yields obtained were 0.59 and 5.35 ton/ha at the level of 150kg N/ha of composted cattle manure in the first cutting, and 0.44 and 3.70 ton/ha at the level of 150kg N/ha of organic raw cattle manure in the second cutting, respectively. The values of $K_{CP}+K_{TDN}/2$ and $K_{ME}$ of sorghum ${\times}$ sudangrass hybrids obtained was 7.76 and 4.46 head/ha at the level of 150kg N/ha of composted cattle manure. The dry matter yield, crude protein and TDN yields of rice straw were 4.95, 0.16 and 2.75 ton/ha at the level of 100kg N/ha of organic raw cattle manure, and the values of $K_{CP}+K_{TDN}/2$ and $K_{ME}$ of rice straw were 1.89 and 3.43 head/ha. The dry matter yield of winter crops, rye+red clover was 4.36 ton/ha in upland field, and rye+hairy vetch was 4.19 ton/ha in paddy field at the level of 100kg N/ha of composted cattle manure. Crude protein and TDN yields of rye+red clover was 0.29 and 2.38 ton/ha at the level of 100kg N/ha of composted cattle manure in upland field, and rye+hairy vetch was 0.30 and 2.48 ton/ha at the level of 80kg N/ha of composted cattle manure in paddy field. The values of $K_{CP}+K_{TDN}/2$ and $K_{ME}$ of rye+red clover was 2.34 and 2.15 head/ha in upland field, and rye+hairy vetch were 2.27 and 2.11 head/ha in paddy field, respectively. As the result, the productivity, feed value, and stock carrying capacity of sorghum ${\times}$ sudangrass hybrids showed higher values with composted cattle manure than organic raw cattle manure. rye+red clover in upland field and rye+hairy vetch in paddy field were most adaptable mixed combinations for roughage production at Gang-wondo area, it may due to their highly productivity, feed value, and stock carrying capacity.

  • This experiment was conducted at the forage experimental field, College of Agriculture and Life Sciences, Seoul National University, Suweon in 1992 and 1993 to investigate the effects of tillage method-conventional and rotary-till, rye (Secde cereale L.) harvest date-early (April 14) and late (April 26), and rye residue treatmentno paraquat(1, 1-dinethyl-4,4'-bipyridinium dichloride) and paraquat in minimizing the adverse effects of the rye residue on growth and yield of succeeding corn(Zea mays L.). Corn plant height during the growing season was slighly taller with conventional tillage relative to rotary-till when rye was harvested in early and treated by paraquat. Corn LA1 during the growing season was slighly increased when rye was harvested in early and where conventional tillage was used with paraquat treatment. There were no differences in the leaf number and silking dates of corn among the tillage methods, harvest dates of rye and paraquat treatments. The dry matter yield of corn was significantly increased by paraquat treatment when rye was harvest in early, but no differences were found in the dry matter percentage, ear percent to total dry matter, and stover, ear and estimated TDN yields of corn among the treatments.

  • Co-incorporation of Leguminosae with Gramineae could reduce the risk of nitrogen starvation phenomena caused by appling green manure of Gramineae alone. The objective of the study was to examine the effect of mixed sowing of hairy vetch and rye seeds on soil quality in mountainous highland. Mixed sowing of hairy vetch and rye increased the yield of green manure and nutrients compared with those for sowing of hairy vetch or rye alone. The yield of green manure from row seeding was $5.3Mg\;ha^{-1}$ compared with $4.8Mg\;ha^{-1}$ for broadcast seeding. Incorporation of the two green manure crops increased yield of red-bean by 58~92% as compared with yield for incorporation of rye alone. The results obtained in the study imply that mixed sowing of hairy vetch and rye can solve the problem of low emergence of hairy vetch in spring and high C/N ratio and rough incorporation of rye, in addition to increase in yield of green manure.

  • In comparison to processed wheat flour products, there is no established method for determining the water absorption of rye flour. The aim of this study was to work out a method using the Planetary mixer P 600 for the determination of water absorption (WA) and the rheological properties in rye dough made from rye flours of 4 different types (I-IV). In the correlation analysis showed that WA had positive correlation with ash, beginning of gelatinization, $125-160{\mu}m$ particles, sedimentation values at 20 and 25 min, bread yield, pH, and total titratable acidity, but had negative correlation with initial viscosity, gelatinization maximum, viscosities on swelling at 25, 28, and $31^{\circ}C$. The WA determined by the Planetary mixer P 600 agreed well with the experimental baking tests.
