This study is performed to investigate the optimal cropping systems to allow cultivation of upland crops to the paddy rice land. This experiment was conducted at Anseong-si Gyeonggi province of Korea in 2015. In order to investigate growth and yield characteristics of foxtail millet, proso millet and sorghum by different paddy-upland rotation systems, three crops foxtail millet, proso millet and sorghum with four varieties of Samdachal, Samdamae, Kyeongkwan1, Hwanggeumjo in foxtail millet, Leebaekchal, Manhongchal, Hwangsilchal, Hwanggeumgijang in proso millet and Nampungchal, Moktaksusu, Aneunbangisusu, Hwanggeumchal in sorghum were examined. Four paddy-upland rotation systems of paddy-upland rotation, paddy-upland-upland rotation, paddy-upland-upland-upland rotation, and upland-paddy-upland rotation system were tested. Days from seeding to heading and ripening of foxtail millet was the shortest in the paddy-upland-upland-upland rotation system, but proso millet and sorghum did not show statistical difference among four rotation systems. In the average of culm length, paddy-upland-upland-upland rotation system showed the highest culm length in foxtail millet (141.5cm), proso millet (159.6cm) and sorghum (138.6cm) respectively among four paddy-upland rotation systems. In average yield per 10a, foxtail millet and proso millet showed the highest each 234.3kg/10a, 176.2kg/10a in paddy-upland-upland-upland rotation system, whereas sorghum was the highest 221.2kg/10a in paddy-upland-upland rotation system. The most suitable crop and varieties in paddy-upland rotation system was judged to be sorghum among three crops and suitable varieties were Samdachal in foxtail millet, Leebaekchal in proso millet and Nampungchal in sorghum respectively.

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 vitro 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 vitro 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 establish proper milling condition and harvesting time for improving the milling recovery of head foxtail millet grain. Brown foxtail millet recovery and the percentage of head foxtail millet recovery were significantly different according to the number of hulling and milling time. Also, the interaction of these factors had influence on brown foxtail millet recovery and the percentage of head foxtail millet recovery. To improve the percentage of head foxtail millet recovery, it was effective to hull grain twice and mill for 1.30 minute. 1000-grain weight of brown foxtail millet, brown foxtail millet recovery, hardness of brown foxtail millet, milling recovery, and the percentage of milling recovery of head foxtail millet grain were significantly different according to harvesting day after heading. For improving the ratio of ripened grain and the percentage of recovery of head foxtail millet, it is recommended to harvest 45 days (accumulated temperature : $1,148^{\circ}C$) after heading (DAH) in early maturing Hwangkeumjo, 50 DAH (accumulated temperature : $1,150^{\circ}C$) in mid-late maturing Samdamae and Kyeongkwan1, and 55 DAH (accumulated temperature : $1,168^{\circ}C$) in late maturing Samdachal.

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, $3977kg\;ha^{-1}$) and proso millet was highest at broadcast seed sowing of 15 kg per ha (2226, $2052kg\;ha^{-1}$) in 2012 and 2013, respectively. Therefore, the optimum rate of sowed seeds under broadcast cultivation was $10kg\;ha^{-1}$ for foxtail millet and $15kg\;per\;ha^{-1}$ 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.

This study was conducted to evaluate the weed suppressing effects of different cropping system including hairy vetch and rye cover crops, polyethylene plastic film, and transplanting film mulching in direct sowing and transplanted foxtail millet field in 2011. Crop growth and development and weed occurrences in the fields were examined to know the efficiency of proposed cropping system. In polyethylene film mulching treatment, heading date of foxtail millet was earlier by 4 days than control, on the other hands, rye cover crop mulching delayed heading date by 8 days. Besides the effect of cover crop on the heading of foxtail millet, the residues changed growth characteristics. Plant height of foxtail millet was increased by 92.4% at hairy vetch treatment although the height of was reduced by 63.7% in the rye cover crop treatment. Hairy vetch treatment showed beneficial effects on foxtail millet growth reduced the occurrences of grasses and broadleaf weeds higher than 90%, as compared to control in foxtail millet fields. While rye cover crop treatment showed poor foxtail millet growth reduced less strongly grasses and broad-leaf weeds by 47% and 90%, respectively. At harvest, yield of foxtail millet was greater in order of hairy vetch cover crop > polyethylene film mulching > rye cover crop ${\fallingdotseq}$ control in both transplanted and direct sown fields.

In order to investigate optimum and marginal sowing date of foxtail millet, proso millet and sorghum in middle area (Anseong, Gyeonggi province) of korea, four levels of sowing date [(May 15(1st), June 6(2th), June 26(3th), July 13(4th)] with mulching and non-mulching were treated in this experiment. We used three crops of foxtail millet, proso millet and sorghum with four varieties of Samdachal, Samdamae, Kyeongkwan1, Hwanggeumjo in foxtail millet, Leebaekchal, Manhongchal, Hwangsilchal, Hwanggeumgijang in proso millet and Nampungchal, Hwanggeumchal, DS202, Moktaksusu in sorghum achieved from RDA. In culm length, sowing date of June 26 was the highest in all varieties of foxtail millet, proso millet and sorghum. Sowing date of May 15 showed the highest ear length in foxtail and proso millet, whereas the highest ear length was obtained from sowing date of June 26 in sorghum. In numbers of leaf, sowing date of May 15 showed the highest in all three crops of foxtail millet, proso millet and sorghum. Days from sowing to heading date were reduced in Samdamae, Kyeongkwan1 and Samdachal as sowing date was late. In Hwanggeumjo it was reduced from the sowing date from May 15 to June 26, but it was same days was taken between June 26 and July 13 sowing date. Days from sowing to heading date of four varieties in proso millet were reduced as sowing date was late. Days from sowing to heading date in sorghum were reduced as sowing date was late, whereas it was increased the $4^{th}$ sowing date of July 13. There were no significant differences in growth and yield characteristics between mulching and non-mulching in four varieties of foxtail millet, proso millet and sorghum with four varieties. The highest grain numbers per panicle, 1000 grain weight and yield per 10a were obtained from sowing date of June 26 in four varieties of foxtail millet, proso millet and sorghum. In sowing date of July 13, all varieties of foxtail millet, proso millet and sorghum were not able to be ripened because of late sowing except Hwnaggeumjo, Manhongchal and Hwanggeumgijang.

Purpose: The study was conducted to investigate the proper working conditions like the mesh size of the concave and the chaffer angle of the oscillating sieve, and the fan speed of the head-feeding rice combine for foxtail millet harvesting. Methods: The study aimed to determine the harvesting conditions for the rice combine harvester at a 0.5 m/s working speed and at $40^{\circ}$ and $55^{\circ}$ sieve chaffer angles. The harvesting loss of the foxtail millet based on the speed of the fan and the oscillating speed of the sieve was measured at three levels of fan speed and oscillating sieve speed. Results: The threshing rates of different foxtail millet varieties were 64.1~83.5% at a mesh size of 7 mm of the concave. In experimental foxtail millet harvesting, the optimal operating condition of the rice combine harvester included a $40^{\circ}$ sieve chaffer angle and a 4.8 Hz oscillating sieve (cleaning shoe) frequency. The grain loss was found to be lower at a $40^{\circ}$ than at a $55^{\circ}$ sieve chaffer angle. In field harvesting using the combine harvester, the lowest harvesting grain loss rate of the foxtail millet varieties ranged between 0.2~0.5% at a 7 mm mesh concave, $40^{\circ}$ chaffer angle, 4.8 Hz sieve frequency, and a 20 m/s fan speed at an engine speed of 2,000 revolutions per minute (RPM). Conclusions: Findings showed that foxtail millet could be harvested using the combine harvester.

Millets are provided considerable amounts of nutrients and gluten-free cereal products and their rich non-nutritional compounds having proven health benefits, especially phenolic compounds. The aim of present investigation was to determine phenolic composition and antioxidant and SOD activity of three different millet of genetic resources namely, foxtail, proso and finger millet. Phenolic compounds were extracted from dehulled grain of genetic resources using methanol and examined for their total phenolic content (TPC), antioxidant activities and superoxide dismutase (SOD)-like activity. The TPC range of hog millet, finger millet and finger millet range from 3.3 to 25.1, 11.1 to 29.0 and 3.8 to 94.3 gallic acid equivalent (GAE)mg/g, respectively. Most of TCP content in dehulled millet grains was distributed from 10 to 20 gallic acid equivalent (GAE)/g, but two accessions of finger millet (IT235690 and 235689) were showed over than 90. The antioxidant activities were measured by 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity. Finger millet and hog millet showed 26.4% and 26.7% in the mean of DPPH scavenging activity percentage, but foxtail millet was 13%. The finger millet showed the higher value than hog and foxtail millet in superoxide dismutase (SOD)-like activity. Particularly, two accessions of finger millet (IT235690 and 235689) showed the highest phenolic content and antioxidant activities among the used millet genetic resources and will be primary resources for finger millet breeding to develop the appropriate breeding strategies.

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.
