  • 'Maek(麥)' which means a barley at present is used as a general name of the kinds of 'Maek(麥)' including barley, what, rye, and so on. However 'Maek(麥)' had meant a wheat when the letter of 'Maek(麥)' had been created at the beginning. And gradually 'Maek(麥)' has been used as a word for the both meaning of a wheat and barley, and now a days become a word only for the meaning of a barley. Therefore 'Mo-Maek' should be translated into 'a wheat and barley', although it is translated into only a barley. In Korea, according to 'Nong-ga-wol-ryung(農家月令)' of Ko, Sang-un(高尙顔) in 1619, the vernalization had been utilized practically 300 years earlier than the Western countries. It is based on a concept of the oriental medicine that a 'Maek(麥)' of the spring seedtime, which keeps the only warmth('Won-yeol-ji-ki(溫熱之氣) (陽氣)' during the growth period in spring-summer time, has less vigorous than a 'Maek(麥)' of the autumn seedtime, which keeps the cold, hot, warmth equally 'Yeol-won-yang-han-ji-ki(溫熱凉寒之氣) (陽氣+陰氣)' during the growth period in the four seasons. If a autumn seedtime barley but which is actually not sowed on time in autumn season is sowed in the spring after the treatment of cold condition (陰氣 autumn-winter condition) artificially, it would be avoided from the abnormal phenomenon that a barley could not come to fruition in case of non-treated seed. Thus as a result of this the agricultural productivity has been able to be improved. An barley is recommended as a food for Um-chung-ji-ki(陰淸之氣) to be served as Bo-myung-ji-ju(保命之主) to be Soyangin. And a wheat which is used as an ingredient of bread because of its expanding feature is a suitable food for Ho-san-ji-ki(呼散之氣) to be served as Bo-myung-ji-ju(保命之主)to the Taeumin.

  • To examine the effects of gibberelin treatment on seed germination of six wild herbaceous species -Dicentra spectabilis, Aster pekinensis, Agastache rugosa, Elsoholtzia ciliata, Boehmeria tricuspis and Pulsatillia cerrma var. chaerophyiloides - in Kangwon-do, pretreated seeds of five species were sowed on plastic pots with mixed soil(sand:peat moss:perlite: vermiculite, 1:1:1:1, v/v) in 23,April 1995. Seeds were soaked in 25,50 ppm gibberelin solution and ground water during 24 hours. Pretreated seeds of Pulsatiilia cerrma var. chaerophylloides were sowed on nursery soil in 1, June 1995. Seed pretreatments in 31, May 1995 were same method. Seed germination rate was measured and compared among species and treatments. Seed germination rate of Dicentra spectabilis, Agastache rugosa and Elsoholtzia ciliata was differed higly significant among pretreatments ,but those of that of Aster pekinensis, Boehmeria tricuspis and Pulsatillia cerrma var chaerophylloides did not significant at 5% level. Gibberelin pretreatment raised seed germination rate of Dicentra spectabilis and Agastaohe rugosa and proper concentration of GA$_3$ was 25ppm and seed germination rate of Elsoholtzia ciliata was highest at GA$_3$ 50ppm plot. The utilization of wild herbaceous species were discussed.

  • The objective of this study was to determine the effect of harvesting time of rice on growth characteristics and dry matter yields of Italian ryegrass (Lolium multiflorum Lam., IRG) 'Kowinearly' after seeding them in paddy field. Experiments were performed in National Institute of Animal Science, RDA (Cheonan, Choongcheongnam-do province of Korea) for four years (2011~2014). Italian ryegrass variety 'Kowinearly' was seeded at experimental paddy fields before rice harvest in late September. Rice were harvested at 10, 20, and 30 days after seeding of IRG. As the harvest time of rice became later, the number of tillering before winter was reduced and IRG plant length before winter was shorter. The dry matter yield of IRG was also reduced. When rice were harvested at 20 days and 30 days after sowing of IRG compared to the rice harvested in autumn at 10 days after sowing of IRG, the number of tillering for IRG before winter was decreased by an average of 19% and 40%, respectively. The winter survival ratio of IRG was decreased by an average of 13% and 19%, respectively. Their dry matter yields were also reduced by an average of 8% and 19%, respectively. The heading date was different from each other in three years. The plant length at the time of IRG harvest in the spring was not significantly different among treatment groups. Taken together, our results suggest that when Italian ryegrass is grown in paddy fields by the method of 'seeding of IRG before rice harvest', rice should be harvested as soon as possible after sowing of IRG 'Kowinearly' in the autumn to increase forage productivity.

  • A field experiment was conducted to evaluate agronomic characteristics, forage quality and dry matter yield of Korean native wild hairy vetch(Vicia villosa Roth) and introduced vetch(Vicia) cultivars from Australia. Seeds were sown on 29 August 1998 and 29 September 1999 at the Livestock Experiment Farm, Keimyung College, Kyeongsan, Kyeongbuk. Vetch plants were harvested on 14 November 1998 and 5 May 1999 and 29 April 2000. 'Haymaker plus' and 'Cappelo woolly pod' (Vicia villosa ssp. dasycarpa(Ten.) Eav.) were higher than 'Namoi' (Vicia villosa ssp. dasycarpa(Ten.) Eav.) in winter survival and 'Popany' (Vicia benghalensis L.) and 'Victa' (Vicia sativa L.) did not overwinter from 1998 to 1999. 'Haymaker plus', 'Cappelo woolly pod', 'Namoi', Korean native wild hairy vetch and Chinese milk vetch were overwintered from 1999 to 2000, except 'Aneto common' (Vicia sativa L.). Fifty percent flowering was observed 23 April for 'Namoi', 24 April for 'Cappelo woolly pod' and 26 April for 'Haymaker plus' from 1998 to 1999. In 1999~2000, fifty percent flowering was observed 12 April for 'Namoi' and 'Cappelo woolly pod', 14 April for 'Haymaker plus', 23 April for Chinese milk, 30 April for 'Aneto common' and Korean native wild hairy vetch. Dry matter yield per hectare was significantly higher(p<0.05) for 'Haymaker plus', 'Cappelo' and 'Namoi' than 'Popany' and 'Vicata' from 1998 to 1999. In 1999-2000, dry matter yield per hectare was higher(p<0.05) for 'Namoi', 'Haymaker plus', 'Cappelo woolly pod' and Korean native wild hairy vetch than Chinese milk vetch (Astragalus sinicus L.) and 'Aneto common'. CP content was relatively high, but Chinese milk vetch and 'Aneto common' were lower than other cultivars. ADF(acid deterguent fiber) was low in Chinese milk vetch, but between the other cultivars were similar. According to the results obtained from this study, it is suggested that 'Haymaker plus' would be recommendable for fall sown vetch for dry matter production.

  • Two field experiments were carried out in 2002 to evaluate effects of the sizes of tubers produced through a wick-based hydroponics on growth and yield of seed potatoes (Solanum tuberosum L. 'Dejima'). Nine sizes of seed tubers (<1, 1~3, 3~5, 5~7, 7~10, 10~20, 20~30, 30~50, and 50~80 g) were used in spring crop. In fall crop, however, tubers except for the 1 g and 50~80 g wereused with tubers 7 and 15 g produced through aeroponics. Emergence rate greatly increased as tuber size was increased up to 10~20 g and then leveled off in both croppings. The number of days from planting to emergence in spring crop was about 34 days regardless of tuber size, while that in fall crop decreased from 34 to 16 days as tuber size increased from 1~3 to 30~50 g. The number of stems per plant, stem length and diameter, and leaf size tended to increase with tuber size. As the seed tuber size increased up to 10~20 g, the number of tubers per plant, average tuber weight, total and seed tuber yields linearly increased and then slowly increased with seed tuber size. Total and seed potato yields were not significantly different between tubers produced through a wick-based hydroponics and an aeroponics when similar sized tubers were planted in the fall cropping.
