우리나라에서 수입되는 곡물은 주로 밀, 옥수수, 콩, 및 쌀이며 이들 곡물은 탄수화물, 단백질, 지질이 약 90%를 구성하고 있다. 탄수화물, 단백질 및 지질은 각각 45, 53, 77%가 탄소로 이루어져 있고 이들 곡물은 완전히 소화 이용되면 탄소부분은 전부 탄산가스로 산화 되어 대기 중에 방출되게 된다. 따라서 1톤을 소비하면 탄산가스 1.51톤, 밀은 1톤을 소비하면 1.63톤, 옥수수와 콩은 1톤을 소비하면 1.56톤의 탄산가스를 방출하게 된다. 우리나라는 곡물 자급도가 26%밖에 되지 않으므로 이는 곡물을 수입하는 만큼 외국에서 탄산가스를 수입하게 되는 결과가 되므로 자급도를 높이는 만큼 탄산가스 방출을 줄이는 결과가 된다. 우리나라는 곡물을 수입하므로서 연평균 2150만톤 이상의 탄산가스를 외국으로부터 수입한 결과가 된다.

Air temperature in Korea has increased by 1.5oC over the last 100 years, which is nearly twice the global average rate during the same period. Moreover, it is projected that such change in temperature will continue in the 21st century. The objective of this study was to evaluate the potential impacts of future climate change on the rice production and adaptation methods in Korea. Climate data for the baseline (1971~2000) and the three future climate (2011~2040, 2041~2070, and 2071~2100) at fifty six sites in South Korea under IPCC SRES A1B scenario were used as the input to the rice crop model ORYZA2000. Six experimental schemes were carried out to evaluate the combined effects of climatic warming, CO2 fertilization, and cropping season on rice production. We found that the average production in 2071~2100 would decrease by 23%, 27%, and 29% for early, middle, and middle-late rice maturing type, respectively, when cropping seasons were fixed. In contrast, predicted yield reduction was ~0%, 6%, and 7%, for early, middle, and middle-late rice maturing type, respectively, when cropping seasons were changed. Analysis of variation suggested that climatic warming, CO2 fertilization, cropping season, and rice maturing type contributed 60, 10, 12, and 2% of rice yield, respectively. In addition, regression analysis suggested 14~46 and 53~86% of variations in rice yield were explained by grain number and filled grain ratio, respectively, when cropping season was fixed. On the other hand, 46~78 and 22~53% of variations were explained respectively with changing cropping season. It was projected that sterility caused by high temperature would have no effect on rice yield. As a result, rice yield reduction in the future climate in Korea would resulted from low filled grain ratio due to high growing temperature during grain-filling period because the CO2 fertilization was insufficient to negate the negative effect of climatic warming. However, adjusting cropping seasons to future climate change may alleviate the rice production reduction by minimizing negative effect of climatic warming without altering positive effect of CO2 fertilization, which improves weather condition during the grain-filling period.

녹비작물은 토양에 환원하여 이용하면 화학비료 절감, 토양의 물리화학적 특성 개량, 토양유실방지, 경관조성 등 다양한 역할을 수행한다. 녹비작물을 농경지에 환원하는 과정에서 발생될 수 있는 탄소 변화를 알아보고자 논토양에 녹비보리, 헤어리베치, 헤어리베치/보리, 화학비료구를 처리하였다. 겨울동안 녹비작물을 통하여 흡수된 탄소량은 헤어리베치는 1.22 ton ha<sup>-1</sup>, 녹비보리는 1.24 ton ha<sup>-1</sup>이었으며 헤어리베치/보리 혼파구는 1.54 ton ha<sup>-1</sup> 이었다. 토양 탄소함량은 벼 이앙 7일전에 가장 높았으며 이후부터 점차 낮아져 수확기까지 비슷한 경향이었다. 녹비종류별로는 헤어리베치와녹비보리구에서 헤어리베치/보리 혼파구보다 높았다. 메탄 발생량은 모든 처리에서 이앙 후 7일에 가장 높았으며, 녹비환원구에서 화학비료구보다 약 17 ~ 25배 더 많았다. 녹비종류별 메탄 발생량은 헤어리베치, 헤어리베치/보리, 녹비보리순이었다. 벼 식물체의 탄소 흡수량은 벼 재배기간 동안 계속 증가하였으며 녹비종류별로는 차이를 보이지 않았다. 수확기의 정조와 볏짚 생산량은 녹비환원구에서 화학비료구보다 5 ~ 13% 많았으며 특히 헤어리베치/보리 혼파구에서는 14.07 ton ha<sup>-1</sup>으로 가장 많이 생산되었다. A green manure crop were used in many ways, such as for reducing chemical fertilizer, improving physical and chemical properties of soils, protecting soil loss, and creating landscape when it"s grown in agricultural land. Experiments were conducted to find out carbon emitted with applying green manure crops in paddy field. Amounts of carbon absorbed in the green manure crops during the winter were 1.22 ton ha<sup>-1</sup> in hairy vetch, 1,24 ton ha<sup>-1</sup> in barley, and 1.54 ton ha<sup>-1</sup> in hairy vetch/barley. The soil carbon content was the highest at days before transplanting of rice and decreased after days after harvesting the plant. Soil carbon contents were higher with hairy vetch or barley treatment than with hairy vetch/barley treatment. The content of emitted methane (CH<sub>4</sub>) was the highest at 7 days after transplanting rice plant, and was 17 ~ 25 times higher with green manure treatments than with chemical fertilizer application. The CH<sub>4</sub> emission was the highest with hairy vetch treatment and than followed by hairy vetch/barley and barley treatments. The content of carbon absorbed in rice plant increased during the cultivation period but was not different with the applications of different green manure crops. The yield amounts of rough rice and rice strow were 5 ~ 13% higher with the green manure treatments than the chemical fertilizer application. In particular, they were the highest with hairy vetch/barley treatment as 14.07 ton ha<sup>-1</sup>.

A field experiment was conducted to determine the optimal transplanting date for ‘Sukwang’, a high grain quality japonica rice, in the southwestern plain area in South Korea. 25-day-old seedlings were transplanted four times by 15 days interval on May 16, June 1, 16, and 30 in 2013 and 2014. Heading dates were August 12 and August 29 in the first and the last transplanting, respectively. Ripening ratio was highest in June 1 and June 16 plots at range of 93 - 94%, and was lowest in 16 May plot. Milled rice yield was the highest in June 1 and June 16 at rage of 538 - 555 kg/10a, and was the lowest in May 16. Head rice yield showed same tendency to milled rice yield. Protein content was not significantly different among treatments except June 1, however, it was slightly increased in the later transplanting plots. Amylose content was increased in the later transplanting plots. According to the regression curve of transplanting dates and grain yield, the optimal transplanting date of ‘Sukwang’ was June 10 in the southwestern plain area in Korea.

본 시험은 몇몇 사료용 피들의 생육특성과 논에서 잡초화 방지를 위하여 국내 논에서 사용량이 많은 제초제들에 대한 반응을 조사하기 위하여 실시되었다. 겨울철 유리 온실 내의 대형 콘크리트 폿트에서 사료 가능성이 높은 피 8계통들의 생육을 조사한 결과 IT170609, IT196421 그리고 EV2012 계통들이 건물중 생산성이 상대적으로 높았다. 출수기에 따른 품종적 특성은 IT170609 계통은 중만생종, IT196421 및 EV2012 계통들은 만생종으로 나타났다. 선발된 사료용 피 3계통에 대한 발아율은 재래종인 강피 보다 높았고, 20 및 25℃에서 뚜렷하였다. 논에서 사료용 피들의 잡초화 방지를 위한 제초제 시험에서 토양처리제인 imazosulfuron+benzobicyclone+penoxsulam 액상수화제는 사료용 피 3계통에 대하여 90% 이상의 효과를 보였다. 경엽처리 제초제들인 cyhalofop-butyl 유제, penoxsulam 액상수화제, metamifop 유제는 사료용 피 6~7엽기까지 매우 높은 효과를 보였다. This experiment was conducted to determine the agronomic characteristics for selection of the excellent barnyard millet and the herbicidal response for their weediness prevention in paddy rice. IT170609, IT195422 and EV2012 have produced more dry matter compared to other barnyard millets tested. In varietal characteristics by heading date, IT170609 showed medium maturing type and IT195422 and EV201 had late maturing type. The germination rate of IT170609, IT195422 and EV2012 on temperature was higher than Echnochloa oryzicola of native species, and it was definitely distinctive at 20 and 25℃. In the herbicidal response for their weediness prevention in paddy rice, imazosulfuron+benzobicyclone+penoxsulam SC showed control effect the extend of over 90% to IT170609, IT195422 and EV2012. Cyhalofop-butyl EC, penoxsulam SC and metamifop EC were very effective by 6~7 leaf stage of barnyard millets tested.
