This study was conducted to determine on the proximate analysis and the several structural carbohydrate for 11 kinds of new vegetables. The samples were dried at 6$0^{\circ}C$ for 24 hrs and ground to pass a 0.5 mm screen. The crude protein and crude fat contents of new vegetables were 2∼3 times higher than those of grain as dry matter basis. However the crude ash content of new vegetables was 7 times higher than that of grain. Total dietary fiber was ranged from 32.61% (Costamary) to 41,22% (Treviso) as dry matter basis. Insoluble dietary fiber was ranged from 21.58% (Red leaf beet) to 28.95% (Treviso) as dry matter basis. Soluble dietary fiber was ranged from 6.60% (Nakai) to 14.70% (Common danelion) as dry matter basis. Total carbohydrates was ranged from 73.62% (Salad bowl) to 36.30% (Red leaf beet) as dry matter basis. Neutral detergent fiber was ranged from 48.83% (Nakai) to 29.60% (Red leaf beet) as dry matter basis. Acid detergent lignin was ranged from 27.65% (Salad bowl) to 2.92% (Corn salad) as dry matter basis. Hemicellulose was ranged from 22.55% (Nakai) to 2.15% (Salad bowl).

Purpose: This study examined the effect of different gluten-free flours on the properties of cookies. Methods: Each gluten-free cookie was made from wheat, brown rice, buckwheat, corn, sorghum, teff, or black rice. Results: Baking loss was highest on sorghum (18.85%) and the lowest on teff (12.73%). The spread factor was highest on brown rice (8.20) and lowest on corn (7.60). The density was similar in all samples (1 g/mL). pH was the highest on buckwheat (6.45) and lowest on wheat (5.96). While L-value, a-value and b-value were lowest on black rice, the ${\Delta}E-value$ was the highest on black rice (35.57). The hardness was highest on wheat (30.28 N) and lowest on teff (14.87 N). The polyphenol and flavonoid content was the highest on buckwheat ($25.97{\mu}g\;GAE/mg$) and the flavonoid content was the highest on black rice ($24.33{\mu}g\;QE/mg$). The DPPH IC50 value was highest on wheat ($352.41{\mu}g/mL$) and lowest on black rice ($33.59{\mu}g/mL$). The ABTS $IC_{50}$ value was highest on wheat ($349.30{\mu}g/mL$) and lowest on black rice ($57.72{\mu}g/mL$). The results of the sensory properties revealed color to be highest on corn (7.33). The top grain was similar in all the samples (5.43-6.57). Flavor was highest on black rice and teff (6.43-6.48). The softness was the highest on wheat, sorghum, teff, and black rice (6.48-7.05). Sweetness was highest on sorghum, teff, and black rice (6.19-6.71). The overall preference also was highest on sorghum, teff, and black rice (6.14-6.48). Conclusion: Gluten-free flours can improve the quality characteristics and antioxidant activities of cookies.

This study was conducted to investigate suitable rice cultivars for various rice based cropping systems in a paddy field in the Yeongnam plain area. Thirteen rice cultivars (5 early, 3 medium and 5 mid-late maturing cultivars) and three transplanting dates (June 5, June 25 and July 5) were evaluated in this study. The mid-late and early maturing cultivars for the July 5 and June 25 transplanting headed before August 30 which is the safe heading date in the Yeongnam plain area, ranging from Aug. 26 - 28 and Aug. 18 - 23, respectively. The safe harvest time of rice for double and triple cropping systems should be before the middle of October for the cultivation of the succeeding winter crops. The rice yield was the highest for the June 5 transplanting regardless of the rice cultivars, and it gradually decreased as the transplanting date was delayed from June 5 to July 5 due to a decrease in the spikelet numbers per panicle number and in the ripened grain rate. In contrast, the other yield parameters that include the panicle number per $m^2$, the 1,000-brown rice weight, and the ripened grain ratio were not significantly affected. The result indicates that based on the milled rice, heading time and harvest time, a medium maturing cultivar (Haiami and Samdeog) would be applicable to a winter barley/wheat, garlic/onion-summer rice double cropping, while a mid-late cultivar (Saeilmi, Saenuri and Hyunpoom) would be suitable for a spring potato/waxy corn-summer rice double cropping in the Yeongnam plain area. On the other hand, an early maturing cultivar (Unkwang, Jokwang and Haedamssal) would be preferable for a triple cropping because of the short growth period of rice.

On the basis of a brief introduction of the mechanized dry farming in Heilongjiang Province, the author states the developing process from the combination of single technics of farm machinery and agronomy to the technical assembly of high yield cultivation technics and its mathematical expression. According to the main temperature accumulated zones, 5 typical comprehensive technical assembly models for the mechanized cultivation technics and their agricultural machinery systems have been listed. They are, the Heihe " 261" wheat and soybean model : the Yi'an big ridge double row film mulching corn model : the Yongchang high yield mechanized soybean and other grain crops six year rotation model for Keshan state farms. The author conclude that the application of mechanized high yield cultivation technical assembly is the key point to transform the Heilongjiang province from big agriculture to strong agriculture, we have to take " high yield , high quality , high efficiency , s stain -ability and earning foreign currency" as the general target and carry out the corresponding policy and measures for the further development of agricuture.
Two rice cultivars (Oryza sativa L.), Hwa-seongbyeo of Japonica type and Taebackbyeo of Indica/Japonica type, were cultivated with hydroponic culture to examine nitrogen effects on the growth responses, contents and utilizations of carbohydrates, and the ripening velocity of grains with three different N levels. Plant height and tiller number were clearly increased to 80 ppm N level compared to 40 ppm N level and then they were slightly decreased in N level of 120 ppm. Higher dry weights were appeared with 80 ppm N level than did with other N levels, showing statistically differences in both cultivars and N levels, while dry weight of roots was heavier with decreasing the N levels. Therefore, T/R ratios were not significantly different among N levels, although there was statistically differences between rice cultivars. After the flowering stage, higher water-soluble carbohydrate (WSC) and water-insoluble carbohydrate (WISC) were contained in stem compared with other parts, showing that WISC of sheath and stem, unlike WSC, was significantly different among N levels. Starch of grain, WISC, was remarkedly increased from 3.0% at just after the flowering to 52.0% and 75.0% at 15 and 30 day after the flowering, respectively, showing that lower N application had faster accumulation of starch in rice grains. N would affect the contents of carbohydrates of each tissue, and starch accumulation in rice grains.

Many reclaimed tideland projects in Korea have been conducted to secure the food self-sufficiency. In fact, the domestic food self-sufficiency has been greatly improved and reclaimed tideland projects contribute to Korea's economic and social development directly or indirectly replacing agricultural lands from urbanization, industrialization. As result, current self-sufficiency of rice reach the demand(104.6%) while rate of upland crops has less than 30% of self-sufficiency rate and corn, wheat, soybeans, etc. are virtually dependent on imports. Domestic price of crop is expected to be unstable by trend of international grain prices. Therefore, developing reclaimed tidelands as upland which is originally constructed for paddy fields could be a good option to become steady in domestic crop market and dedicate to ensure a stable food security. The study to prepare measures for dealing with disasters in reclaimed tidelands of west coast district is required in order to utilize those sites for infra construction of multi-utilization in those sites and The result of flooding analysis in this study can suggest policy direction for practical utilization of reclaimed tidelands in yellow sea area.
Acidovorax avenae subsp. avenae is the causal pathogen of several hosts including oats corn foxtail millet wheatgrass sugarcane and rice. The pathogen is a seedborne pathogen of rice and known to occur widely in rice growing countries. The pathogen cause inhibition of germination brown stripe on the leaf curling of the leaf sheath and abnormal elongation of the mesocotyl of irce. Bacterial colonies grow slowly and are convex circular and creamy with tan to brown center. The causal baterium is Gram-negative and rod shape with a single polar flagellum Nonfluorescence poly-$\beta$-hydroxybutyrate accumulation and precipitate formation around the colony on the medium are useful in the differentiation of this bacterium from other subspecies of A. avenae as well as nonfluorescent bacteria pathogenic to rice. This bacterium has belonged to the genus of Psdeudomonas but recently was transferred to the new genus Acidovorax on the basis of bacteriological and molecular biological data. However the difference of biochemical characteristics protein profile of the cell and host range among strains should be more clarified. To develop an effective control strategy for this disease understanding of detailed life cycle of the disease ritical environmental factors affecting disease development on each host and relationship to grain discoloration of rice are prerequisite. Although the affected area has been world-widely reported there is on recent progress on the understanding of the bacteriological and ecological characteristics of the causal bacterium and control means of the disease.
Varieties of the cereals produced in the Biblical times and the ways these cereal foods have been grafted into Korean food culture has been pursued, and the regulations of agricultural life and the metaphors or parables of cereals represented throughout the Bible have been studied. The word "grain" appears eight times in the KJV and one hundred seventeen times in the RSV. On the other hand, the word "corn" shows up one hundred and one times in the KJV but not in the RSV at all. Wheat, one of the earliest cultivated and the most important grains for food is mentioned fifty two times in KJV and generally the rich in those days lived on wheat in the parched state or in the form of bread. Barley, one of the staple cereal crops of Palestine is referred to thirty six times in the KJV. It was less expensive than wheat and so was used mainly for the food of such animals as horses, donkeys and cattle, but sometimes it was mixed with flour and used for making bread for men, mostly for Poor men. The spelt (in ASV and RSV) and the rie(in KJV) appearing in Exodus 9:32 is a kind of grain, which is translated into Na-mack (in Hangul Revised Bible ; HRB), Ssal-bori (in Hangul Common Translated Bible : HCB) and Ho-mil (in Hangul King James Bible; HKJB) but which should be put into Spelt-mil in Korean. The lentil appearing in Genesis 25 : 34 is translated into Pat (red-bean) and Bul-kong respectively in HRB and HCB but the same word in the Second Book of Samuel is translated into Pat in both HRB and HCB. HCB translates lentil into Bul-kong in Genesis and into Pat in the Second Book of Samuel (23:11). HCB and HKJB which put lentil into Pat in previous parts translate the word into Nok-tu in the Second Book of Samuel. The word, lentil here should be put into lentil-kong and parched pulse into "Poken-Chong-ja" not into Poken-Nok-tu. Millet which is translated into Cho should be put into Gui-jang. filches should not be classified as a grain or a cereal but as a flavor or a condiment, so the word filches should be put into So-Hoi-hyang or Hoi-hyang. Regulations in reference to agriculture are included in the Bible. That is, it is seen that the Bible regulates the observance of the sabbatical year and feasts, the partition of land, how to sow and so on. It is also observed that grains are used for metaphors or parables: wheat represents the peaceful times and straws are compared to trifles. As seen above, there should be more prudent examinations and standards for the translation of grains into Pat, Pul-kong, Nok-tu, Gui-ree, Ssal-bo-ri and Na-mack.i-ree, Ssal-bo-ri and Na-mack.
'Hwangdaok', a new maize F1 hybrid (Zea mays L.), was developed by the maize breeding team at the National Institute of Crop Science (NICS), RDA in 2016. The high-yielding yellow dent hybrid named 'Hwangdaok' was obtained by crossing between two inbred lines, 'KS203' and 'KS190'. After advanced yield trial in Suwon in 2012, regional yield trial was subsequently carried out to evaluate the growth and yield of 'Hwangdaok' at three different locations from 2014 to 2016. The number of days to silking of 'Hwangdaok' is 76. The plant height is 262 cm and ear height ratio is 51%, which are similar to those of 'Jangdaok'. It has resistance to lodging. The number of ears per 100 plants is 95. The ear length is 21.3 cm and weight of 100 seeds is 34.7 g, similar to those of 'Jangdaok'. It has moderate resistance to southern leaf blight (Bipolaris maydis) and European corn borer (Ostrinia nubilalis). The grain yield (10 ton/ha) of 'Hwangdaok' is 6% higher than that of 'Jangdaok'. The seed production rate of 'Hwangdaok' is acceptable due to good synchronization of flowering period during crossing between the seed parent, KS203, and the pollen parent, KS190, in Yeongwol. F1 seed yield was 1.68 ton/ha. 'Hwangdaok' can be a suitable cultivar to plain areas in Korea. (Variety registration No. 7502).

This study was done to investigate the interplanting effects of corn, when a corn hybrid with tillers (IK derivaties) was interplanted with a corn hybrid without tillers(Jinjoo Ok). The interplanting ratios of two hybrids, IK and Jinjoo Ok, were 1 to 1, 1 to 2, 1 to 3, 2 to 1, and 3 to 1. The interp1anting effects were compared with monoculture for major agronomic characteristics. 1. The plant height was increased when interplanted regardless of the interplanting ratios of the two hybrids. The general growth of IK hybrid was a little hindered when the interplanting ratio of Jinjoo Ok hybrid increased. 2. The number of tillers produced by the IK hybrid increased until 40 days after emergence and appeared to increase as the interplanting ratio of IK hybrid increased. 3. When monocultured, the fresh weight of IK hybrid per 10a was 8,096kg and and 6,677kg at silking and dough stages, respectively and these were 77%, 53% over the fresh weight of Jinjoo Ok at the sarne stages. When IK and Jinjoo Ok hybrids were interplanted in 1 to 1 ratio, the fresh weight of IK was 20% higher than that of Jinjoo Ok monocultured. 4. The highest grain yield per 10a was obtained from the Jinjoo Ok hybrid monocultured and the yield was 434kg. Even the interplanting ratios between IK and Jinjoo Ok were 1 to 1 and 1 to 3, the grain yield of Jinjoo Ok was 16% and 13% over the IK, respectively. 5. Root and stalk lodging of IK hybrid was 29% when monocultured and seemed to increase as the interplanting ratio of Jinjoo Ok increased. The lowest lodging was found when the interplanting ratio of IK and Jinjoo Ok was 1 to 1. 6. Stem diameter of IK hybrid was also decreased as the interplanting ratio of Jinjoo Ok increased. The ear height of IK was lowered as the interplanting ratio of IK was increased. The two hybrids tested seemed to have tolerance to the black streaked dwarf virus(BSDV).
