  • These experiments were conducted at the upland of Livestock Farm, Seoul National University, Suweon to determine the growth characteristics, winter-hardiness and forage yield of selected southern and northern-types of winter rye (Secale cereale L.) in comparison with the Korean native rye over two seasons, 1977-78 and 1980-8 1. During the 1977-78 season, most southern-type rye varieties except Explorer and Abruzzi headed 2 to 6 days earlier than the Korean native rye and 6 to 10 days earlier than northerntype rye varieties Rymin and Puma, while in 1980-81 southern-type rye varieties headed 5 to 7 days earlier than the Korean native rye, therefore, the Korean native rye seemed to be medium in maturity. There were no significant differences in winter-hardiness among different rye varieties with the exception of the lowest winter survivals of Wintergrazer 70, Explorer and triticale, and Gator, Explorer and Florida Black during the 1977-78 and 1980-8 1 seasons, respectively. Southern-type rye varieties tended to yield more forage than northern-type and the Korean native rye varieties when harvest was made in the later part of April. During 1977-78 season, Vita-Graze, Elbon and Athens Abruzzi rye varieties produced significantly more forage than the Korean native rye, but in 1980-81 Wrens Abruzzi rye produced significantly more forage than the Korean native rye. Based on the results of the two seasons, southern-type rye varieties,Vita-Graze, Athens Abruzzi, Elbon and Wrens Abruzzi could be recommended as a source of green forage for livestock in April in middle-northern parts of Korea.

  • This syudy was conducted to increase the utility of forage rye which are suitable to be cultivated at high altitude Taekwllyong area. For that purpose two cultivars of rye (winter-more, kool-glazer) were cultivated for 3years using a randomized block design with 3 replications. The dry matter digestibility (DMD) was evaluated with the pelleted rye hay produced by adding sodium hydroxide and then the TDN value was calculated by the DMD. By adding NaOH, DMD and TDN value of rye pellets (Y=46.92+ 1.8X, ~ 0 . 9 7 )w ere increased significantly (p<0.05) and NDF (neutral detergent fiber) decrease significantly. However, ADF (acid detergent fiber) and lignin did not significantly decrease (p<0.05). Rye could be cultivated as a second crop after com at high altitude area in the same year and pelleted with NaOH in order to increase the nutritive values (p< 0.05).

  • In order to reduce the problems from overlapping between rye harvest and maize seeding dates, and also to improve the growth, productivity and nutritive value of rye (Secale cereale L.), an experiment was carried out to determine the variety effect of rye on the forage production system, and seeding date effect on the yield and quality of rye. The experiment was conducted in the forage testing field of S.N.U., Suweon, from September 1988 to May 1989. The dry matter and in vitro digestible dry matter yields of rye harvested 14 April were 5.2 t and 4.6 t/ha with an early maturing rye variety, Winter more, but 3.1 t and 2.8 t/ha were obtained with a late maturing rye variety, Kodiak. When seeding date was delayed, a significant decrease in dry matter yield was observed. ADF and NDF contents, and IVDMD of an early maturing rye, Winter more, harvested 14 April were 25.6, 44.8 and 81.9 %, but those of a late maturing rye, Kodiak, were 21.1, 39.5 and 88.9 %, respectively. ADF and NDF contents of rye were increased as the seeding date was delayed, but ail forage ryes from different seeding dates as well as varieties were recorded as the 1st grade proposed by market hay grades. The dry matter and in vitro digestible dry matter yields of rye harvested at 80 %heading stage were significantly decreased as delayed seeding date, but no significant differences were found between early and late maturing varieties. No differences in ADF and NDF contents, and IVDMD of the rye harvested at 80% heading stage were found among the treatments, but all forage ryes were evaluated as the 4 th grade proposed by market hay grades.

  • In order to reduce the problems from the presence of rye crop residues in maize establishment and yield, and also to improve the growth, productivity and nutritive value of rye(Seca1e cereal L.). an experiment was canied out to determine the variety effect of rye on the forage production system and the eft'ect of seeding and harvesting dates on the production and quality of rye. 'This experiment was conducted at the forage testing field of S.N.U., Suweon, from September 1986 to May 1989. Heading date of an early maturing rye variety, Wintermore. was earlier 10 days than that of a late maturing rye variety, Kodiak. A 15-days delay in the seeding dates of early and late maturing varieties of rye tended to delay the heading dates of the rye varieties for 3 and 4 days, respectively. Dry matter and in vitro digestible dry matter yields were markedly increased with earlier seeding date. Before 20 April, the DM and IVDDM yeilds of an early maturing rye variety, Winterrnore. were higher than those of a late maturing rye variety, Kodiak. However, no such a trend was found between the early and late maturing varieties of rye after 27 April. Less than 35% of ADF was recorded until the harvesting dates of 13 and 27 p r i l for early and late maturing rye varieties, respectively, but less than 46% of NDF was maintained until the harvesting drtte of 13 April for botg varieties. Based on the results obtained from this experiment. it may be concluded that the most desirable forage production from corn-rye double cropping system is to advance the seeding time of rye toward the first 10 days of September as well as harvesting time toward the first heading stage with an early maturing rye variety.

  • Rye(Secale cereale L.) shows lower dry matter yield and nutrient content when it was harvested before wintering. This study was conducted to investigate how effect forage rape(Brassicu napus Subsp oleifera), which carries early maturity and can be harvested before wintering, on the increase of the forage yield and nutrient content when rye was sown mixed with the rape. Optimum sowing rate of the rye/rape mixture was also pursued in this study. The five treatment of rye single, rape single, ryel20+rape 1Okg/ha, rye84+rape 7kg/ha and rye60+rape 5kg/ha were sown on 2 September 1989. Rape single plot was cut one time(l9 November 1989) and the other plots were cuted two times(19 November 1989 and 20 May 1990). In botanical composition of the mixtures, rape recorded dominant ratio with 64~69% at the autumn cut. The rye84+rape 7kg/ha mixture plot marked the highest dry matter yield with 4.46t/ha among all the experimental plot at the autumn cut(P<0.05). In year total yield of dry matter(t/ha), rye single, rape single, rye120+rape IOkg/ha, rye84+rape 7kg/ha and rye60+rape 5kg/ha marked 13.6, 4.1, 12.7, 12.9 and 11.8, respectively. In crude protein content, the rye single plot was 17.2% at the autumn cut on the other hand the mixture plots showed increasing tendency with 18.0~19.9%. In crude fiber content, the mixture plots were remarkably lower than rye single plot. In year total yield of crude protein, rye84+rape 7kg/ha mixture plot showed the highest yield with 1.6lt/ha among all the experimental plots. Ratio of crude protein yield to crude fiber yield, rye84+rape 7kg/ha tended to be higher than the other mixture plots. It is confirmed that the rye/rape mixture can produce more forage than the rye single cropping when they are harvested in late autumn, besides the mixture forage contains higher crude protein than that rye single forage. It can be said that the rydrape mixture is more useful than the rye single cropping, and optimum sowing rate of the mixture is 84kg/ha of rye+7kg/ha of rape.

  • 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.

  • The present study analyzes the role of Lactic Acid Bacteria Mixture (LBM) on improving rye silage quality. Rye of four different stages (Booting, Heading, Flowering, and Late flowering) was collected and silage was prepared. The nutrient profile analysis of experimental silage groups showed no significant changes between control and LBM inoculation. Interestingly, the pH of rye silage in LBM treatments showed significant reduction than control (p<0.05) in all stages of rye silage. However, lowest pH (3.69) resulted on booting stage among other stages of rye. Subsequently significant lactic acid production was noted in all stages of LBM inoculation than control. Conversely maximum lactic acid production of (5.33%DM) was noted at booting stage followed by (4.86%DM) in heading stage. Further the lactic acid bacterial (LAB) count in LBM inoculated group showed significant increase than control. Similarly, the silage of booting stage group registered maximum LAB population ($63.7{\times}10^6CFU/g$) after that heading stage ($32.3{\times}10^6CFU/g$). Further significant reduction in yeast growth and no fungal growth was noted in all LPM treatment groups. Hence, LBM inoculants could be a better additive for improving rye silage quality.

  • 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.
