"Youhan" (Hordeum vulgare L.), a new whole-crop barley cultivar, was developed by the breeding team at National Institute of Crop Science, RDA in 2012. Youhan has the growth habit of III, a light green and mid-sized leaf, hooded and lax-type spikes. The cultivar showed 107 cm of culm length, 641 spikes per
. The heading date of Youhan was May 1, which is one day later than that of the check cultivar "Yuyeon" in upland, and 2 days earlier than that of Yuyeon in paddy field. The maturation time was similar to check cultivar Yuyeon on June 4 in upland and May 31 in paddy field. In terms of winter hardiness and resistance to lodging and disease, Youhan also performed better than the check cultivar. The average forage dry matter (DM) yield in the regional yield trial was approximately 12.6 ton
and 12.0 ton
in upland and paddy field, respectively, which were 6% and 5% higher than that of the check. The yield also showed 7.3% of crude protein, 26.8% of ADF (acid detergent fiber), 47.8% of NDF (neutral detergent fiber), 67.7% of TDN (total digestible nutrients), and a higher grade of silage quality for the whole-crop barley. Fall sowing cropping of Youhan is recommended only in those areas where the average daily minimum-mean temperatures in January are higher than
, and it should not be cultivated in mountainous areas of Korea.

This experiment was conducted to evaluate the effect of seeding methods and application levels of nitrogen fertilizer on the yield and forage quality of whole crop rice (WCR). The WCR variety "Namil" was directly seeded on April 25 and transplanted on May 25. Five levels of nitrogen fertilizer were applied (90, 110, 140, 170 and 200 kg/ha). There were no significant differences (p<0.05) of the emergence date, heading date and disease resistance based on the nitrogen fertilizer rates; however, the WCR became dark at higher nitrogen fertilizer rates. The plant height increased at higher nitrogen fertilizer rates and the tiller number showed the same trend. In contrast to a direct seeding method, transplanting increased the tiller number. The dry matter (DM) content did not show a certain tendency based on nitrogen fertilizer rates, while the fresh and dry matter yields increased with incremental changes of the nitrogen fertilizer rates (p<0.01), and the transplant method increased the yield size. In yield analysis, the plot direct-seeded with 140 kg N/ha and the transplanting with 170kg N/ha showed the highest yields. The crude protein (CP) content increased with higher nitrogen fertilizer rate, but there was no significant differences between transplant and direct-seeding methods. The content of ADF (acid detergent fiber) and NDF (neutral detergent fiber) increased with higher nitrogen fertilizer rate, but total digestible nutrient (TDN) content decreased with increased nitrogen levels. Although high nitrogen applications increased the fresh and DM yields, the 140 kg/ha nitrogen fertilizer level is recommended as the proper nitrogen fertilizer level, considering both yield and the environments.

This study was conducted to investigate the effect of different stockpiled periods on the nutritive value and productivity of mixed orchardgrass tall-fescue pasture (MOTP). This experiment was conducted at Jeju (island), South Korea, from Sep. 2012 to Nov. 2012. The DM yield of the MOTP had the highest in treatment in late August (2,983 kg/ha). The DM yields of swards were increased significantly by shortening the stockpiled period. The CP of the MOTP was 16.5% to 18.16%, and there did not appear to be a consistent trend in accordance with the duration of the stockpiled periods. The NDF and TDN content of the MOTP increased with the delay of the stockpiled periods, but there is a significant difference between the short- and long-stockpile periods; however, the ADF content of the MOTP decreased with shortened stockpile periods, but again, there is a significant difference between the two periods. In addition, P, Ca, Mg, Na, and Zn of MOTP increased by delaying the stockpile period, but Mn and Cu of MOTP decreased. As shown in the results of this research, the yield of MOTP was not increased by the atrophy of the growth of MOTP due to high temperatures in case where the MOTP was stockpiled from the beginning of August. The stockpile period of MOTP should therefore be started at the end of August to yield a stockpile of MOTP in the autumn.

This study was conducted to evaluate on agronomic characteristics, dry matter (DM) and digestible dry matter (DDM) yields of summer sowing sorghum hybrids (Sorghum bicolor (L) Moench) at Seongju in Gyeongbuk from 2013 to 2014. The experiment was arranged in randomized complete block design with three replications. Sorghum hybrids were seeded
of July, 2013 and 2014. Sorghum hybrids were harvested on
November, 2013 and
November, 2014. The observed average heading date was October 5, 8 and 9 for Sordan79, Sprint and SX17 respectively. The DM yield of 'SX17', 'Sordan79', and 'Sprint' was 24.2, 23,9 and 23.4 ton/ha, respectively and DM yield of those were significantly higher (p<0.05) than other three cultivars in 2013. DM yield of 'SX17', 'Sprint' and 'Sordan79' was 20.8, 20.0 and 19.3 ton/ha, respectively and DM yield of those was significantly higher (p<0.05) than other three cultivars in 2014. The DDM yield of 'SX17', 'Sordan79', and 'Sprint' was also higher (p<0.05) than other three cultivars in 2013 and 2014. ADF content of sorghum hybrids was low, whereas DDM was high. The results of this study indicated that traditional sorghum-sudangrass hybrids ('SX17', 'Sordan79') and sudan grass-sudangrass hybrid ('Sprint') than late flowering sorghum-sudangrass hybrid ('PACF8350') and sorghum-sorghum hybrids ('SS405', 'Sugar grazer') would be recommended for DM and DDM yields in the southern Korea.

"Seedgreen" (Secale cereal L.), a new rye cultivar was developed by National Institute of Crop Science (NICS), RDA in 2013. It was developed from an open pollination from within 10 rye varieties or lines including "Chochun" in 1995. The line "SR95POP-S1-140-9-1-3-7-5-3" was selected for its excellent agronomic appearance, and was placed in yield trials for three years from 2008 to 2010. The new cultivar was designated "Homil50" and was placed in regional yield trials at the five locations around Korea from 2011 to 2013, during which time the name "Seedgreen" was given. This cultivar is an erect plant type and of a long size, with a dark-green leaf color, a yellowish-white colored, medium-diameter culm, and a brown-colored, medium-size grain. The heading and maturation dates of Seedgreen were April 22 and June 16, which were 3 days and 2 days earlier than that of "Gogu", respectively. Seedgreen also showed better winter hardiness and a greater resistance to lodging and wet injury compared to those of the check cultivar. Over three years, the average dry matter yield of Seedgreen was 8.3 ton
(fresh yield = 39.8 ton
), which was harvested in late April and was lower than that of the check cultivar Gogu. The seed productivity of Seedgreen was approximately 4 ton
, which was 16 % more than that of the check. Seedgreen was higher to than Gogu in term of protein content (10.5% and 9.7%, respectively), total digestible nutrients (TDN) (58.3% and 57%, respectively), and TDN yield
(4.81 ton and 4.77 ton, respectively). This cultivar is recommended as a fall sowing crop in areas where the average daily minimum-mean temperatures are higher than
in January, and as a winter crop for whole-crop forage before the planting of rice or green manure around Korea.

This study was carried out to offer basic information for the promotion of the goat industry and the improvement of mountainous-pasture management by investigating seasonal changes in forage and livestock productivity according to the grazing-pasture type. The forage productivity of rangeland was the highest (p < 0.05) in summer and decreased in autumn; but that of pasture was the largest (p < 0.05) in spring and had relatively stable productivity with minor seasonal differences, although it decreased slightly in autumn. The dry matter content was not seasonally different at pasture, but it was changeable from spring to autumn at rangeland. The crude protein content increased in autumn at pasture (p < 0.05), and decreased in summer and autumn compared with spring at rangeland. The crude fiber content was lower and the ether extract was higher at pasture compared with rangeland. The average daily gain of the goats was different depending on forage productivity and pasture type; consequently, the lowered forage productivity at rangeland compared with pasture means that rangeland needs to be changed or improved to a pasture type that provides a more effective grazing system for goats.

DOI : 10.5333/KGFS.2015.35.2.119
In this study, we sought to evaluate the growth characteristics and seed productivities of domestic tall fescue that were cultivated with differing combinations of drill widths and nitrogen-application rates in early spring; the examination was conducted at the National Institute of Animal Science, RDA, from 2013 to 2014. The main plots were three widths of 15 cm, 30 cm, and 45 cm, and the subplots were subject to nitrogen-application rates in early spring of 45 kg/ha, 90 kg/ha, 135 kg/ha, and 180 kg/ha. The growth and development characteristics did not vary by treatment in terms of drill width and early-spring nitrogen application. Tall fescue Purumi showed a stable seed productivity of two tons or greater when the drill width was set at 15 cm and 90 kg/ha of nitrogen was applied in early spring. The narrower the drill width, the greater the numbers of both the ears and seeds, while the length of the ear was longer when the drill width was wider. Regarding the influence of the drill width and early-spring nitrogen application on the productivity of seed-producing straw, the dry matter productivity was higher when the drill width was narrower; however, no particular trend was observed with respect to different amounts of fertilizer. The average production amount of the first round of straw after seed gathering was 6,920 kg/ha. The second round produced an average 8,134 kg/ha of dry matter.

Journal of The Korean Society of Grassland and Forage Science, volume 35, issue 2, 2015, Pages 125~130
DOI : 10.5333/KGFS.2015.35.2.125
The objective of this study was to investigate the feasibility of using near infrared spectroscopy (NIRS) to discriminate between grass spices. A combination of NIRS and chemometrics was used to discriminate between Italian ryegrass, perennial ryegrass, and tall fescue seeds. A total of 240 samples were used to develop the best discriminant equation, whereby three spectra range (visible, NIR, and full range) were applied within a 680 nm to 2500 nm wavelength. The calibration equation for the discriminant analysis was developed using partial least square (PLS) regression and discrimination equation (DE) analysis. A PLS discriminant analysis model for the three spectra range that was developed with the mathematic pretreatment "1,8,8,1" successfully discriminated between Italian ryegrass, perennial ryegrass, and tall fescue. An external validation indicated that all of the samples were discriminated correctly. The discriminant accuracy was shown as 68%, 78%, and 73% for Italian ryegrass, perennial ryegrass, and tall fescue, respectively, with the NIR full-range spectra. The results demonstrate the usefulness of the NIRS-chemometrics combination as a rapid method for the discrimination of grass species by seed.

DOI : 10.5333/KGFS.2015.35.2.131
The objective of the present study was to evaluate the effect of moisture content on the haylage quality of Italian ryegrass (Lolium multiflorum). Seven levels of moisture content (60%, 55%, 50%, 45%, 40%, 35%, and 30%) were tested in this experiment. The results show that the feed value, crude-protein content, neutral detergent fiber, acid detergent fiber, and in vitro dry-matter digestibility were not significantly different as the moisture content decreased. The pH and lactic-acid content, however, decreased significantly as the moisture content decreased, whereas the content of acetic and butyric acid increased significantly. We concluded that a moisture content within a range from 60% to 40% is best for Italian-ryegrass haylage.

DOI : 10.5333/KGFS.2015.35.2.137
This study was carried out to investigate the growth characteristics, yield, and chemical compositions of corn hybrids for silage according to the drainage depths in a lowland paddy field. The experimental design was arranged in a randomized block design with four treatments and three replications. The drainage depths of the four treatments were 0 cm, 20 cm, 30 cm and 50 cm. Tip-filling degree, ear length, and ear circle were higher in the 30 cm and 50 cm treatments compared with the other treatments (p < 0.05); but the plant length, leaf length, leaf width, ear height, stem diameter, and stem hardness were not significantly different (p < 0.05). The brix was higher in the order of 20 cm > 0 cm > 50 cm > 30 cm treatment. The fresh yield, dry matter yield, and TDN yield increased as the drainage depth increased (p < 0.05). The crude-protein and crude-ash content were highest in the 50 cm treatment (p < 0.05), but the crude-fat, NDF, ADF, and crude-fiber levels were not significantly different (p < 0.05). The total mineral content was higher in the order of 0 cm > 30 cm > 20 cm > 50 cm treatment (p < 0.05). Fructose, glucose, and sucrose were highest in the 20 cm treatment. The total amino-acid (EAA + NEAA) content was the highest in the 50 cm treatment. Based on these results, greater drainage depths increased the yield and feed value of silage corn.

DOI : 10.5333/KGFS.2015.35.2.145
This experiment was conducted to evaluate the productivity and silage quality of domestically developed forage crops in Korea. A variety of rye ("Gogu"), oat ("Samhan"), three Italian ryegrass ("Kogreen", "Kospeed" and "Kowinearly") and two barley ("Yuyeon" and "Youngyang") were evaluated at an experimental field of Grassland and Forage Division, National Institute of Animal Science, RDA in Korea. Gogu showed the highest dry matter yield among the forage crop but the lowest was Samhan. Crude protein (CP) was higher in the oat and Italian ryegrass varieties. The total digestible nutrient (TDN) content levels were similar with the except for the rye. The acidity (pH) of the oat silage was the lowest among forage crop species. Higher lactic acid content levels were found in the Kogreen and Samhan compared to the other varieties (p<0.05). According to Flieg's score, all of the silages were assigned a
quality grade with the exception of the Gogu. These results suggest that domestically developed forage crop varieties show high performance in terms of productivity and silage quality, and are therefore recommendable forage crop varieties for Korea.

This study was conducted from 2013 to 2014 in the middle region of Korea to compare the agronomic characteristics, forage production, and quality of kenaf, maize, and a sorghum
sudangrass hybrid. The three crops used in this study were kenaf "Hongma 300," maize "Kwangpyeongok," and the sorghum
sudangrass hybrid "Jumbo" (headless type). The sugar contents of the kenaf, maize, and sorghum
sudangrass hybrid were 5.4%, 4.4%, and 2.5%, respectively. The emergence rates and lodgings of the three crops were sound, as they were more than 80% and 1.5, respectively. The fresh yields of kenaf, maize, and the sorghum
sudangrass hybrid were 117,521 kg/ha, 73,336 kg/ha, and 133,334 kg/ha, respectively, and the dry matter (DM) yields were 28,598 kg/ha, 19,951 kg/ha and 20,083 kg/ha, respectively. The DM yield of kenaf was significantly the highest among the three crops (p<0.05). However, the total digestible nutrients (TDN) contents of the kenaf, corn, and sorghum
sudangrass hybrid were 43.3 %, 72.0 %, and 54.8 %, respectively, and the in vitro digestible dry matter (IVDDM) yields were 44.4%, 73.7%, and 59.6 %, respectively; therefore, the TDN yield of the corn was 13 % significantly higher than that of the kenaf (p<0.05). The TDN yields of the kenaf, corn, and sorghum
sudangrass hybrid were 12,472 kg/ha, 14,350 kg/ha, and 11,001 kg/ha, respectively. Among the three crops, the content of neutral detergent fiber (NDF) and acid detergent fiber (ADF) were highest in the kenaf. This study shows that the kenaf had a good forage productivity but a low forage quality.

DOI : 10.5333/KGFS.2015.35.2.159
Fresh rice straw silage (RSS) was prepared with lactic acid bacteria (LAB) and chlorella (CA) at the experimental field of National Institute of Animal Science, Cheonan Province, Korea. This experiment consisted of the following eight treatments: control treatment without CA and LAB; treatment of 0.1% CA applied without LAB; treatment of 0.5% CA applied without LAB; treatment of 1.0% CA applied without LAB; treatment of only LAB inoculation without CA; treatment of 0.1% CA inoculated with LAB; treatment of 0.5% CA inoculated with LAB; and treatment of 1.0% CA inoculated with LAB. The content of crude protein of RSS significantly elevated with increased concentration of CA (p<0.05). The levels of acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrient (TDN), and in vitro dry matter digestibility (IVDMD) showed no significant improvement in all treatments when compared to control. However, the quantity of lactic acid in RSS increased in CA and LAB alone inoculated treatments. Similarly, lactic acid significantly increased in LAB with CA treatments when compared to control. In addition, the number of LAB in LAB treatment increased as compared to control and significantly increased by an increase of CA concentration (p<0.05). Therefore, the nutritive values and quality of RSS can be improved by the addition of CA.

This study investigated the effect of novel Lactobacillus plantarum KCC-10 and KCC-19 on the quality and fermentation characterization of alfalfa silage at the experimental field of National Institute of Animal Science, Cheonan Province, Korea, from 2013 to 2014, and this experiment consisted of the following three treatments: control without lactic acid bacteria; treatment inoculated with L. plantarum KCC-10; and treatment inoculated with L. plantarum KCC-19. The contents of crude protein, acid detergent fiber, neutral detergent fiber, total digestible nutrient and in vitro dry matter digestibility of alfalfa silage were not affected by either L. plantarum KCC-10 or KCC-19. The pH of alfalfa silage in L. plantarum KCC-10 and KCC-19 treatments decreased as compared to control. The level of lactic acid in L. plantarum KCC-10 and KCC-19 treatments increased (p<0.05), whereas the contents of acetic acid and butyric acid decreased(p>0.05). In addition, the numbers of lactic acid bacteria in L. plantarum KCC-10 and KCC-19 treatments increased as compared to control (p<0.05). Therefore, these results suggest that the inoculation of L. plantarum KCC-10 and KCC-19 into alfalfa silage can improve the quality of silage through increased lactic acid content and lactic acid bacteria.
