본 연구에서는 취반 방법이 조(삼다메, 삼다찰)를 첨가하여 취반한 밥의 항산화 활성에 미치는 영향을 살펴보기 위해 조 첨가비율별(0, 5, 10, 15, 20%)로 제조한 밥의 기능성분 및 라디칼 소거 활성을 살펴보았다. 백미와 조의 일반성분 분석 결과 수분 함량과 탄수화물은 백미에서, 조단백, 조지방 및 조회분 함량은 조에서 더 높은 함량을 나타내었다. 호화특성은 조 첨가비율이 증가함에 따라 최고점도, 최저점도, 강하점도, 최종점도, 치반점도가 감소하였다. 취반방법에 따른 조 첨가 밥의 폴리페놀 함량은 일반밥솥으로 취반하였을 때 높은 함량을 나타내었으며, 10% 이하에서는 물 첨가와 일반밥솥으로 취반한 경우가 높았고 15 및 20%에서는 발효주정을 첨가하여 일반밥솥으로 취반한 경우가 높은 함량을 나타내었다. 반면, 총 플라보노이드 함량은 물 첨가와 일반밥솥으로 취반한 경우가 높은 함량을 나타내었고, DPPH 및 ABTS 라디칼 소거 활성은 발효주정 첨가와 일반밥솥으로 취반한 경우에 높은 활성을 나타내었다. 본 연구 결과 같은 비율로 삼다메와 삼다찰 취반 시 전반적으로 발효주정의 첨가와 일반밥솥으로 취반하였을 때 높은 페놀화합물 함량과 DPPH 및 ABTS 라디칼 소거 활성을 확인할 수 있었으며, 이는 취반방법에 따른 잡곡밥의 생리활성 연구에 기초자료가 될 것으로 생각된다. This study was carried out to analyze the antioxidant components and activities of cooked mixed grain rice-added foxtail millet with different addition rates (5, 10, 15, and 20%) and cooking methods. The two foxtail millet varieties used in this study were non-waxy foxtail millet, ‘Samdame’, and waxy foxtail millet, ‘Samdachal’. Cooked mixed grain rice-added foxtail millet was cooked by general and high pressure cooking methods with and without fermented alcohol. Except for breakdown viscosity, pasting characteristics of foxtail millet were reduced with increasing amounts of foxtail millet. Water-binding capacity and swelling power significantly decreased with increasing amounts of foxtail millet, whereas water solubility index significantly increased. Total polyphenol and flavonoid contents increased with increasing amounts of foxtail millet. DPPH and ABTS radical scavenging activities also increased with increasing amounts of foxtail millet. Moreover, foxtail millet cooked by general cooking method with fermented alcohol showed higher antioxidant effect compared to other cooking methods. In this study, antioxidant components and activities of cooked mixed grain rice-added foxtail millet with different addition rates and cooking methods can be used as basic data for manufacturing processed products.

The seed-borne mycoflora of sorghum and foxtail millet collected from different growing areas in South Korea were isolated and taxonomically identified using dry inspection, standard blotter and the agar plate method. We investigated the in vitro and in vivo germination rates of disinfected and non-disinfected seeds of sorghum and foxtail millet using sterilized and unsterilized soil. The percent recovery of seed-borne mycoflora from the seed components of sorghum and foxtail millet seeds was determined and an infection experiment using the dominant species was evaluated for seedling emergence and mortality. A higher number of seed-borne fungi was observed in sorghum compared to that of foxtail millet. Eighteen fungal genera with 34 fungal species were identified from the seeds of sorghum and 13 genera with 22 species were identified from the seeds of foxtail millet. Five dominant species such as Alternaria alternata, Aspergillus flavus, Curvularia lunata, Fusarium moniliforme and Phoma sp. were recorded as seed-borne mycoflora in sorghum and 4 dominant species (Alternaria alternata, Aspergillus flavus, Curvularia lunata, Fusarium moniliforme) were observed in foxtail millet. The in vitro and in vivo germination rates were higher using disinfected seeds and sterilized soil. More seed-borne fungi were recovered from the pericarp compared to the endosperm and seed embryo. The percent recovery of seed-borne fungi ranged from 2.22% to 60.0%, and Alternaria alternata, Curvularia lunata and 4 species of Fusarium were isolated from the endosperm and embryo of sorghum and foxtail millet. Inoculation of the dominant seed-borne fungi showed considerable mortality of seedlings. All the transmitted seed-borne fungi might well be a primary source of infection of sorghum and foxtail millet crops.

This study was conducted to evaluate effects of seeding rate and depth during broadcast sowing on growth and yield of foxtail millet and proso millet over 2 years. The rate of sowing seeds was adjusted to 5, 7, 10 and 20 kg per ha on foxtail millet, and 5, 10, 15 and 30 kg per ha for proso millet. Sowing depth was 0.5, 1, 3, 5, 7, and 10 cm used tractor rotary attachment for shallow-tilling. The rate of seedlings standing when foxtail millet and proso millet were sowed to a depth of 0.5~5 cm was 72.0~78.0% and 73.0~80.5%, respectively. Plant height and weight at the three-leaf stage after emergence was highest for the treatment with 3 cm rotary depth. As the rate of broadcast seed sowing increased, plant length, diameter, seed length, and seeds on the panicle decreased. The grain yield of foxtail millet was highest with broadcast seed sowing of 10 kg per ha (3652, 3977 kg ha-1) and proso millet was highest at broadcast seed sowing of 15 kg per ha (2226, 2052 kg ha-1) in 2012 and 2013, respectively. Therefore, the optimum rate of sowed seeds under broadcast cultivation was 10 kg ha-1 for foxtail millet and 15 kg per ha-1 for proso millet. Optimum sowing depth for foxtail and proso millet under broadcast cultivation was 3 cm, using a rotary tractor attachment for shallow-tilling. 최근 건강 기능성 농산물로 각광받고 있는 조, 기장의 생산량과 자급률 향상을 위하여 산파재배에 적합한 파종량과파종깊이를 알아보기 위하여 생육 및 수량특성을 알아보았다. 파종량은 조는 5, 7, 10, 20 kg ha-1, 기장은 5, 10, 15, 30 kg ha-1를 실시하였고, 파종깊이는 0.5, 1, 3, 5, 7, 10 cm 로 실시하였다. 조와 기장의 파종깊이의 출현율은 0.5~5.0 cm에서 72.0~78.0%, 73.0~80.5%였다. 출현 후 3엽에서 초장과 무게는 로터리깊이 3 cm에서 조, 기장 모두 가장 크거나 무거웠다. 또한, 파종량이 증가함에 따라 초장, 경직경, 이삭장 및 이삭당 종실수가 감소하는 것으로 보였다. 1 ha당 수량은 조는 연차간 모두 10 kg ha-1처리에서 1년차3,652 kg, 2년차 3,977 kg으로, 기장에서도 연차간 모두 15 kg ha-1처리에서 1년차 2,226 kg, 2년차 2,052 kg으로 가장높은 수량을 보였다. 따라서 조, 기장 모두 산파 재배시 조는 10 kg ha-1, 기장은 15 kg ha-1으로 로터리 3 cm 깊이에서 파종하여 재배할 경우 수량증대에 유리할 것으로 생각된다.

In this study, we investigated the disease, insect damage, growth, and yield characteristics of sorghum and foxtail millet in an organic paddy-upland rotation system at Anseong-si Gyeonggi province, Korea, in 2016. Seven varieties of sorghum and foxtail millet are used in this study. A rotational upland field and continuously cropped upland field were compared in order to establish an optimum cultural method and to select the best sorghum and foxtail varieties for a paddy-upland rotation system. The incidence rate of major diseases was higher for sorghum than for foxtail millet. Moktaksusu (22.8%) had the highest incidence rate among sorghum varieties. Hwanggeumchal (7.0%) had the highest incidence rate among foxtail millet varieties. DS202 (89.3%) was the most severely damaged by Ostrinia furnacalis larva, which is the main pest of sorghum and maize. The weed numbers, and the weed fresh and dry weights were lower in the rotational upland field than in the continuously cropped upland field. Futhermore, the number of weed plants decreased by 42% and the dry weight of weeds decreased by 33% in the rotational upland field compared to the continuously cropped upland field. The culm length of sorghum and foxtail millet were 7.9 cm, and 3.4 cm longer, respectively, in the rotational upland field than in the continuously cropped upland field. The average yield of sorghum per 10 a increased by 90% in the rotational upland field compared to continuously cropped upland field. However, there was no significant difference between the rotational upland field and the continuously cropped upland field for foxtail millet. The most suitable varieties for a paddy-upland rotation system were judged to be Hwanggeumchal, Donganmae, and DS202 for sorghum, and Samdachal, Samdamae, Dahwangmae for foxtail millet.

Cultivation techniques of proso millet (Panicum miliaceum L.) and foxtail millet (Setaria italica L.), such as sowing, weeding, and harvesting, are often not properly utilized, resulting in low productivity rates. The goal of this study was to develop cultivation techniques to increase millet productivity rates and reduce labor inputs. We evaluated the effects of different machine sowing methods compared with manual sowing methods from 2014 to 2016. The three machine sowing methods were dibbling, drilling, and broadcasting. Compared with manual sowing, the broadcasting method decreased labor times by 16.07 and 14.23 hr 10 a-1 for proso and foxtail millets, respectively. Proso millet showed greater culm lengths at 138 and 125 cm with the broadcasting method for two years, whereas foxtail millet after three years had greater culm lengths from both the drilling and broadcasting methods. Both crops exhibited the thickest culm stems in the 3rd year. The greatest number of seeds of the panicle were from the manual sowing method in both crops. Compared with manual sowing, broadcasting increased grain yields by 15– 35% and 9.1–28% for proso and foxtail millets, respectively. Therefore, we suggest that the application of broadcasting in mechanical sowing will increase labor efficiency and yields of proso and foxtail millets. 기장과 조의 생산량과 자급률 향상을 위하여 기장과 조의 기계화에 적합한 파종방법을 알아보기 위해서 지금까지개발된 기장과 조의 기계화 파종방법에 따른 생육특성 및 수량특성을 알아보았다. 시험처리는 인력점파, 높은이랑 기계점파, 기계산파, 넓은이랑 줄뿌림 파종방법으로 실시하였다. 노동투입시간에서의 기장의 산파는 인력점파 대비16.07 hr 10a-1 절감되었고, 조에서도 인력점파 대비 산파에서 14.23 hr 10a-1 절감되었다. 간장은 기장에서 2 및 3년차에서 산파 처리구에서 가장 큰 138, 125 cm가 조사되었으며, 조에서는 3년 모두 줄뿌림과 산파 처리구에서 가장 큰것으로 나타났다. 간경에서는 기장과 조에서 3년 모두 가장굵은 것으로 나타났다. 종실수는 인력점파 처리구에서 많은 것으로 조사되었다. 수량에서는 기장의 경우 대조구인인력점파 대비 산파에서 15∼32% 증수되었다. 조의 경우에서도 대조구인 인력점파 비해 산파에서 9.1∼28% 증수 되었다. 따라서 기장과 조의 기계화 파종시 산파하여 재배할 경우 노동효율 및 수량증대에 유리할 것으로 생각된다.

This study was carried out to analyze the pasting and antioxidant characteristics of cooked mixed grains consisting of germinated millet and rice with varying addition rates and cooking methods. In this study, we chose two foxtail millets: glutinous (‘Samdachal’) and non-glutinous (‘Samdame’), along with a glutinous proso millet (‘Ibaekchal’). Cooked mixed grain rice-added germinated millet was cooked by general and high pressure cooking methods, with and without fermented alcohol. The peak and trough viscosity of germinated millet were decreased significantly with increasing amounts of germinated millet. The phenolic compounds and radical scavenging activity of cooked rice-added germinated millet increased significantly with the addition of germinated millet (p<0.05). The total polyphenol contents of cooked rice-added germinated Samdachal, Samdame, and Ibaekchal were 127.74~194.11, 128.20~192.56, and 128.88~171.28 μg GAE/g, respectively. The total flavonoid contents were 13.79~30.23, 14.77~25.99, and 15.28~29.56 μg CE/g, respectively. DPPH and ABTS radical scavenging activities were 3.31~5.73 and 6.31~9.69 mg TE/100 g for cooked rice-added germinated Samdachal; 3.14~8.58 and 6.05~10.19 mg TE/100 g for Samdame; and 3.37~7.45 and 6.27~9.27 mg TE/100 g for Ibaekchal, respectively. In this study, phenolic compounds and radical scavenging activity of cooked mixed grain rice-added germinated millet with different addition rates and cooking methods can be used as basic data for manufacturing processed products.

본 연구에서는 잡곡 재배 시 가장 문제가 되는 잡초관리방법을 개선하고 피복작물과 잡곡의 작부체계를 개선 및 효율을 비교하기 위하여 피복작물인 헤어리베치와 호밀이 잡곡생육과 수량에 미치는 영향을 알아보았다. 1. 헤어리베치구에서 수수의 초장과 엽록소 함량, 엽록소 형광, 종실수량은 무처리구 보다 각각 46.4%, 88.7%, 7.9% 높았으며 수량 또한 105.1% 많았다. 조의 경우도 무처리구 보다 각각 45.6%, 50.9%, 37.8%로 초장, 엽록소 함량, 엽록소형광이 높았으며 종실수량도 134.9% 높은 결과를 보였다. 호밀처리구에서 수수의 초장과 엽록소 함량, 엽록소형광은 무처리구 보다 각각 7.1%, 10.8%, 10.8% 높았으나 수량은 25.8% 감소하였다. 조는 무처리구 보다 각각 28.9%, 17.2%, 1.3% 감소하였으며 수량 또한 119.1% 감소하였다. 헤어라베치구에서 잡곡에 대한 녹비 효과가 좋았다. 2. 잡곡 출수 전 헤어리베치와 호밀의 잡초 발생량은 무처리에 비해 감소하였고 건물중은 헤어리베지와 무처리 차이가 없었으나 호밀은 31.6% 감소하여 호밀에서 잡곡 출수 전 잡초억제 효과가 인정되었다. 그러나 출수 후에는 혜어리베치의 장초발생량은 159%, 건물중은 55.2% 증가하였으며 호밀에서는 각각 55.2%, 10.9%로 증가하였다. 따라서 출수 후 헤어리베치와 호밀의 잡초 억제효과는 미약하였다. 3. 발생한 주요 잡초종은 총 16종으로 일년생잡초 12종으로 가장 많은 비중을 차지하였다. 특히 8월~9월의 우점 잡초종으로는 헤어리베치는 바랭이와 돌피였으며, 호밀 처리 시 강아지풀, 바랭이, 돌피 등이 우점하였다. This study was conducted to evaluate the weed suppressing effects of two winter cover crops, hairy vetch and rye in foxtail millet and sorghum fields in 2010. Crop growth and development and weed occurrences in the fields were examined to know the efficiency of proposed cropping system. In hairy vetch treated plots, heading of minor cereals occurred early. The heading date was earlier by 1 day and 2 days in sorghum and foxtail millet, respectively. However, rye treatment delayed heading by 12 days and 8 days in sorghum and foxtail millet, respectively. Besides he effect of cover crop on ear emergence of crops, the Besides changed growth-related characteristics. Plant height, chlorophyll content and chlorophyll fluorescence of sorghum ere increased in hairy vetch treatment by 46.4% 88.7% and 7.9%, respectively. In foxtail millet, the characteristics ere also increased by 45.6%, 50.9% and 37.8%, respectively, s compared to control. Yields of sorghum and foxtail millet were increased by 105.1% and 135% as compared o control by hairy vetch treatment, respectively. However, he yields of cereal crops were decreased by rye cover crop treatment, the yields of sorghum and foxtail millet were decreased by 25.8% and 119.1%, respectively. Rye cover crop treatment inhibited crop growth suggesting nitrogen starvation in rye treated plots. In rye treatment, plant height, chlorophyll contents and chlorophyll fluorescence of sorghum ere slightly decreased by 7.1%, 10.8% and 10.8%, respectively, as compared to control whereas the inhibitory effects were greater in foxtail millet. Weed occurrences based n weed number in hairy vetch and rye plots were reduced n weed number in hairy vetch and rye plots were reduced y 27% and 20%, respectively. The smothering effect was weakened or disappeared after heading of crops. Weed number and dry weight in hairy vetch plot were increased by 159% and 55.2%, respectively, as compared to control. The results implied that weed suppressing of cover crops could be reduced drastically after heading of crops.

대표적인 잡곡 중에 하나인 조의 이용성 제고를 위하여 누룩 및 조 첨가량을 달리하여 제조한 발효주의 이화학적 특성을 검토한 결과 알코올 함량은 처리구간에 유의적인 차이를 보이지 않았다. 당도는 조 첨가량이 증가함에 따라 감소하는 경향을 보였다. 발효주 특유의 단맛을 위해 30% 정도의 조를 첨가하는 것이 양호할 것으로 여겨졌다. pH는 조 첨가량이 증가함에 따라 SH업체 누룩을 이용한 발효주는 약간 감소하는 경향을 보였고 BS업체 누룩은 증가하는 것으로 나타났으며, 산도는 pH와 반대의 경향을 보였다. 탁도는 조 첨가량이 증가함에 따라 감소하는 경향을 보여 맑아지는 것을 확인할 수 있었다. 조 첨가량에 따라 L 및 b-value는 감소하는 경향을 보였으며, a-value는 증가하는 경향을 보였고 색차(ΔEab)는 증가하는 것으로 나타났다. 발효주의 유기산은 oxalic acid, lactic acid 및 acetic acid가 주를 이루었고 유리당은 glucose만이 검출되었고 조 첨가량이 증가함에 따라 대체적으로 감소하는 경향을 보였다. 관능검사결과 조를 첨가할 경우 선호도가 감소하는 것으로 나타났으나, BS업체 누룩을 이용하여 조를 70% 첨가한 발효주가 가장 양호한 관능적 특성을 보였다. This study was carried out to compare the physicochemical characteristics of Korean traditional wine fermented from foxtail millet and nuruk at different mixing rates. The alcohol contents of fermented wine ranged from 12.70 to 13.38%. Two kinds of commercial nuruks, SH and BS nuruk, were used. The brix degrees of foxtail millet wine fermented by SH and BS nuruks were 21.6 and 22.4°Bx, respectively. The pH, total acidity, and turbidity of the wines fermented by SH and BS nuruks were 3.74 and 3.40, 1.40 and 1.51%, and 0.441 and 0.149, respectively. With an increase in the amount of foxtail millet, brix degree, pH, turbidity, b-value and L-value decreased, and total acidity and a-value increased. Total color difference (ΔEab) parameter of the wine fermented by SH nuruk were 8.58, 22.59 and 22.55, while those by BS nuruk were 0.35, 4.08 and 7.16 in 30, 70 and 100% addition rates of foxtail millet, respectively. With an increase in the amount added of foxtail millet, glucose content decreased. The organic acids such as lactic acid and acetic acid were predominantly detected in the fermented wine. Finally, based on sensory evaluations, the wine fermented by BS nuruk showed the best overall quality at the 30% addition rate of foxtail millet.

In 2015, a nationwide survey was carried out to investigate about occurrence pattern of virus infecting foxtail millet. A total 100 foxtail millet leaf samples showing virus-like and abnormal symptoms were collected in the seven main cultivated regions of Korea. Four viruses were identified using reverse transcription polymerase chain reaction and RNA sequencing. Of the collected 100 foxtail millet samples, 10 were Barley virus G (BVG), 4 were Rice stripe virus (RSV), 1 was Northern cereal mosaic virus (NCMV), and 1 was Sugarcane yellow leaf virus (ScYLV) infection. To our best knowledge, this is the first report of BVG and NCMV infecting foxtail millet in Korea and ScYLV is expected as new Polerovirus species. This research will be useful in breeding for improved disease-resistant foxtail millet cultivars. 2015년, 조 바이러스 발생양상을 구명하기 위하여 전국적인 조사를 실시하였다. 주요재배단지 7개 지역에서 이상 증상과 바이러스 병징을 보이는 식물체 100점을 수집하여, RT-PCR 진단과 RNA sequencing 방법을 이용하여 전체 4종의 바이러스를 동정하였다. 수집한 시료에서는 Barley virus G (BVG)가 10점, Rice stripe virus (RSV)는 4점, Northern cereal mosaic virus (NCMV), Sugarcane yellow leaf virus (ScYLV)가 각각 1점씩 검출되었다. 이들중에서 BVG와 NCMV는 국내 조에서 첫 발생보고이며, ScYLV는 Polerovirus속의 신종으로 예상된다. 본 연구결과는 조 식물체의 무병종자와 저항성 품종개발을 위한 기초연구 자료로 이용 가능할 것으로 생각된다.
