        A winter forage tetraploid rye (Secale cereale L.) cultivar, ‘Daegokgreen’, was developed at the Department of Central Area Crop Science, NICS, RDA in 2016. The mutant line ‘CG11003-8-B’, which was induced from rye cultivar ‘Gogu’ (diploid) by colchicine treatment, was selected for its excellent agronomic performance and was placed in preliminary yield trials for one year, 2013. The line was designated “Homil59” and was tested for regional yield trials at the four locations in Korea from 2014 to 2016. Finally, the new cultivar was named as the ‘Daegokgreen’ (grant number 8274). The leaf of cultivar ‘Daegokgreen’ is wide, long and dark-green color. The cultivar also has a big-size grain with light-brown color. The heading date of cultivar ‘Daegokgreen’ was April 17 which was 2 days later than that of check cultivar ‘Gogu’. The tolerance to cold and wet injury, and resistance to powdery mildew and leaf rust of the new cultivar were similar to those of the check cultivar but the resistance to the lodging of the new cultivar was stronger than that of the check. The average roughage fresh and dry matter yield of the new cultivar after 10 days from heading were 37.0 and 7.7 MT ha-1, respectively, which were similar to those (38.4 and 8.0 MT ha-1) of the check cultivar. The roughage quality of ‘Daegokgreen’ was higher in crude protein content (8.9%) than that of the check cultivar (7.9%), while was similar to the check in total digestible nutrients (56.9%). This cultivar is recommended for fall sowing forage crops at all of crop cultivation areas in Korea.

        This study aimed to determine the optimal harvesting time for wheat to make grain silage, in Honam region of Korea. We harvested wheat grain every third day from 30 to 42 days after heading (DAH). The moisture content decreased from 61.6% at 30 DAH to 42.8% at 42 DAH. Yield of wheat grain significantly increased from 30 to 42 DAH (p< 0.05). Yield at 39 DAH (3.46T/ha) was not significantly different from that at 42 DAH (p< 0.05). With respect to the feed value of wheat grain silage, the amount of crude protein, crude fiber, and crude ash was different by harvesting time (p< 0.05). However, the amount of total digestible nutrients (TDN) from 30 and 42 DAH was not significantly different. The pH of wheat grain silage from 30 to 42 DAH was between 3.8 and 4.5 and it was stable until 39 DAH (p< 0.05). The lactic acid content of wheat grain silage from 30 to 42 DAH decreased from 3.08% to 1.10%. With respect to moisture content, yield, feed value, and fermentation, the optimal harvesting time for wheat grain silage was 39 DAH.

        Oats (Avena sativa L.), which are known as one of the forage crops of Korea, have good livestock palatability and are popular to cattle farmers because of their high dry matter. However, the cultivation of double cropping in the rice field was reluctant due to the late maturing for farmers to plant rice continuously. 'Hi-early', a winter oats for forage use, was developed by the breeding team at National Institute of Crop Science, RDA in 2016. It was derived from a cross between ‘517A2-121’(IT133383) and ‘CI7604’ (IT133379). Subsequent generations followed by the cross were handled in bulk and pedigree selection programs at Suwon, Iksan and Jeonju, respectively. After preliminary and advance yield test for 2 years, ‘SO2004015-B-B-23-1-3-7’, designated as a line name of ‘Gwiri92’, were subsequently evaluated for earliness and forage yield during 3 years in four parts such as Jeju (upland), Yesan (upland), Iksan (upland), and Jeonju (paddy), from 2014 to 2016, and finally named as ‘Hi-early’. Cultivar ‘Hi-early’ has the characteristics of medium leaves of green color, thick diameter culm, and medium grain of brown color. Over 3 years, the heading date of ‘Hi-early’ was about 9 days earlier than that of check cultivar ‘Samhan’ (April 26 and May 5, respectively). Average forage fresh yield of ‘Hi-early’ harvested at milk-ripe stage was similar to check cultivar (40.2 tone ha-1 and 40.0 tone ha-1, respectively), and dry matter yield also was similar to check cultivar (14.2 tone ha-1 and 14.0 tone ha-1, respectively). Cultivar ‘Hi-early’ was lower than the check cultivar ‘Samhan’ in terms of the protein content (6.2% and 7.0%, respectively) and total digestible nutrients (61.0%, and 62.5%, respectively), while the TDN yield was more than the check (7.91 tone ha-1 and 7.64 tone ha-1, respectively). Fall sowing cropping of ‘Hi-early’ is recommended only in areas where average daily minimum mean temperatures in January are higher than -6°C, and it should not be cultivated in mountain areas, where frost damage is likely to occur.

        This study was conducted to investigate the feed value and silage quality according to storage period and film layers in whole crop oat silage. The crude protein content was increased in all silage during the storage periods compared to those before silage, under prolonged storage period slightly and the number of film layers of silage, six layer were higher than four layers, but no significant. NDF and ADF contents were also increased in all silage of storage duration compared to those before silage, but they was similar level between storage duration and number of film layers. TDN content was decreased of the storage duration. However, it was similar under the storage duration and the number of film layers. The pH value was decreased during prolonged storage period and six layers was lower than four layers depending on the film layers. In the organic acid contents, lactic acid and acetic acid were increased under the prolonged storage duration, and butyric acid was higher significantly(p<0.05), six layers of the film were showed higher lactic acid and lower butyric acid(p<0.05). Therefore, oat silage should be used within 6 months it was when treated with 4 layers, if considering the long-term storage, it is desirable to treat it with 6 layers or more.

        This study was carried out to investigate the optimal harvesting time, feed value and fermentation quality of barley and wheat for the making of chopped whole crop silage substitute for formula feed. As a result, the moisture content of barley and wheat decreased with a late harvest, and barley progressed faster than wheat. The plant height was similar with harvesting time, and the number of spikes decreased with prolonged period after heading. The dry matter yield and TDN yield of barley harvested at 35 and 40 days after heading were significantly higher than those at 30 days after heading and wheat was significantly higher at 40 and 45 days than at 35 day after heading(P<0.05). Crude protein content of barley and wheat were increased with later harvesting time, and crude fiber, crude fat and crude ash were slightly decreased, but not statistically significant. NDF and ADF content of barley decreased with later harvesting time, and those showed similar level in wheat. TDN content of barely was slightly increased but there was no difference in wheat. Comparing the effects of fermentation on feed value of chopped whole crop silage, the approximate compositions were slightly increased after fermentation, but the difference was not significant. Fermentations resulted in increasing the pH value of barley silage with late harvesting time, but decreasing the lactic acid content(p<0.05). A pH value of wheat silage showed similar level in different harvest time, and lactic acid content was decreased. Considering the quantity and quality of fermentation, barley and wheat can be used for making chopped silage of whole crop silage when they were harvested at 35 days and 40~45 days after heading, respectively.

        This study was conducted to evaluate the possibility of expanding the usage of whole crop silage from beef cattle and dairy cow to hogs and chickens. For this purpose, a crushing device was developed to crush whole crop silage. The crushed silage was sealed, and analyzed for its feed value. The silage varieties used for the experiment included Saessal barley and Geumgang wheat. Whole crop barley and wheat were crushed in the crushing system as a whole without separating stems, leaves, grains, etc.. When the crushed whole crop silages (CWCS) were analyzed, full grain, grains above 10 mm in size, grains 5~10 mm in size, and grains below 5 mm in size accounted for, 20%, 4%, 27%, and 49 %, respectively. In order to facilitate the fermentation of CWCS, inoculated some fermenter into each CWCS sample (barley or wheat). As control, another set of sample was not inoculated. Crude protein (CP), ether extract (EE), crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), lignin, cellulose content, total digestible nutrient (TDN), and relative feed value (RFV) of fermenter-inoculated Saessal barley were 2.45 %, 1.61%, 8.95%, 16.94%, 9.52%, 1.01%, 8.51%, 81.38%, and 447.5%, respectively. The CP, EE, CF, NDF, ADF, lignin, cellulose content, TDN, and RFV in the other sample of Saessal barley without inoculation of fermenter were 2.57%, 1.62%, 9.61%, 18.25%, 10.13%, 1.10%, 9.04%, 80.90%, and 412.9%, respectively. The CP, EE, CF, NDF, ADF, lignin, cellulose content, TDN, and RFV of fermenter-inoculated Geumgang wheat sample were 2.43%, 1.27%, 10.99%, 19.49%, 11.23%, 1.46%, 9.77%, 80.03%, and 382.6%, respectively. The CP, EE, CF, NDF, ADF, lignin, cellulose content, TDN, RFV of the other set sample of Geumgang wheat sample without the inoculation of fermenter were 2.28%, 1.44%, 10.08%, 18.02%, 10.44%, 1.26%, 9.18%, 80.65%, and 416.9%, respectively. The TDN and RFV content in the fermenter-inoculated Saessal barley were 81.38% and 447.5%, respectively, while the one in the fermenter-inoculated Geumgang wheat were 80.03% and 382.6% respectively. When the feed value of whole crop barley and wheat silage without crushing process was compared to the feed value of whole crop barley and wheat silage made from crushing system, the latter appeared to be higher than the former. This could be due to the process of sealing the crushed silage which might have minimized air content between samples and shortened the golden period of fermentation. In conclusion, these results indicate that a crushing process might be needed to facilitate fermentation and improve the quality of silage when making whole crop silage.
