  • The important legumes in Korea are mungbean, red bean, kidney bean and cowpea. Mungbean has traditionally been used for mook (jelly-like starch gel) preparation. Cowpea has recently been utillized for substitution of mungbean. The major use of sediment of red bean is for the sweet paste. The studies related to legume starches and flours (air-dried sediment) in Korea are concentrated on the understanding of the properties of mook. The structure of starch, gelatinization and gelling properties of legume starches and flours are reviewed with emphasis of Korean literatures.

  • From the reports of the Korean National Nutrition Survey, the trend of fat intake was analyzed from 1969 to 1991. Total fat intake of 1991 was 2.1 times higher than that of 1,969 and animal fat intake was elevated 3.2 times during 23years. Among vegetable foods, the consumption of cereals and their products was decreased gradually, however, the amount of legumes and their products intake was increased slowly. In addition, among animal foods, the intakes of meats and their products, eggs, fishes and shellfishes, milk and milk products were increased greatly. the main fat source was gradually changed form cereals and their products in 1969 to meats and their products in 1991. In 1969, 7.2% of total energy was derived from fat wheres 16.6% was derived from fat whereas 16.6% was derived from fat in 1991. Among 1,952 households surveyed in 1991, the fat intakes of 576(29.4%) and 104(5.3%) households were over 20 and 30%, respectively, of total energy intake. The 42.7% of the households had more than 50% of the total fat from animal fat. From the above results, it is suggested that the nutrition education program is need to prevent excess fat intake.

  • This experiment was carried out to study the effect of cutting frequencies(2, 3: one time grazed after 2 cuts, 3, 4, 6 cuts per year) and nitrogen fertilization(0 and 120 kg per ha and year) on botanical composition of permanent grassland at the "Federal Research Institute for Agriculture in Alpine Regions(Gumpenstein)," Austria The results are summarized as follows: 1. With only fertilizing phosphorus(P) and potassium(K),mean annual dry matter yields were 6.9 - 8.4 ton per ha and highest when only one time grazed after 2 cuts, but fell progressively with increase in cutting frequency and additonal fertilization of nitrogen. The average nitrogen efficiences expensed as dry matter yieldsfig) per feltilized nitrogenfig per ha) were 10.3 kg. 2. When N fertilizer was applied, the proportion of tall and medium grasses in the mixed swards increased by 30 - 50% compared with only fertilizing PK. Whereas swards with fertilizing only PK generally stimulated composition of the legumes at the expense of the grasses(30 - 50%). 3. Although the proportion of tall and medium grasses(Trisetum flavescens and Dachlis glomerara) and tall herbs(hntodon hispidus, Taraxacum oflcinale and Aegopodium podagraria) increased by infrequent cutting, frequently cutting plots helped increase the proportion of short grasses(Poa pratensis and Poa trivialis), especially where plots both had been applied with nitrogen fertilizer. 4. Nitrogen fertilization resulted in higher existence of herbs and weeds such as Taramcum oficinale. Aegopodium podagraria, Galium mllugo, Anthriscus silvestris and Lamium album. 5. Due to unusually high or low cutting frequencies such as 4 cuts or 2 cuts per year increased botanical compostion of Heracleum sphondylium.hondylium.

  • To find out the effects of phosphatic fertilizer application level on the dry matter yield and nutrient contents of grasses, this experiment was arranged as a randomized complete block design with six treatments(0, 50, 100, 150, 200 and 250kg $P_2O_5$/ ha) and conducted at hill land in Gwangju, Gyeonggi Province from September, 1989 to October, 1992. The results obtained are summarized as follows : 1. As the phosphatic fertilization level increase, the early growth and cover degree of grasses wintered were more favorable and plant length was higher. 2. With 150kg $P_2O_5$/ ha application for three years, the average dry matter yield of grasses, 10,112kgl ha was sirnilared to that of 200kg $P_2O_5$/ ha and the yield was composed of 77.2% grasses(7,808kg/ ha), 19.2% legumes(l,937kg 1 ha) and 3.6% weeds(367kg / ha). 3. The crude protein and energy productivity of grasses increase as phosphatic fertilization level was increased, but those were not different between 150 and 250kg $P_2O_5$ 1 ha. Therefore, phosphatic fertilization level must be applied with 150kg / ha for a reasonable management in hilly grassland.

  • Cheju Island has an optimal environment for herviborous animal production. However, the infrastructure has been degraded under the pressure from the development of tourism and thus the technological development for livestock production has not been great. This is the time to re-evaluate and re-direct the system of livestock production on the island. My suggestions on the development of grassland agriculture on the island are as follows : 1. Grassland area of Cheju, 65,695 ha should be maintained and the local government should try to improve more grasslands which can hold 3 or more cattle per ha on pasture. including enterpriseowned lands. 2. For better management of co-operatives village. the local government should evaluate the conditions of the grasslands yearly after being grazed and suggest a new management method accordingly. 3. In order to strengthen grassland research. it is recommended that Cheju Experiment Station be reorganized as a Grassland Research Institute or Department of Grassland Science be added. 4. [mport of good forage varieties. especially legumes, from foreign countries and distribution to farmers after adaption studies, are required to improve nutritive values of forage produced. 5. Methods for production of good quality forage seeds at rcasonablc prices should be established.

  • In this study, we attempted to find alternative materials to replace Cotten seed meal(CM) using the wastes of bean sprouts by-product in bottle cultivation of Pleurotus ostreatus. In Proximate analysis, the protein content of BW was slightly lower than that of CM, but the growth characteristics of mushrooms were similar to those of control when byproduct of bean sprouts was used. In addition, the amino acid composition of fruit body did not show a significant difference in the treatment section. Therefore, it is judged that BW could be a suitable substitute for CM in the cultivation of Pleurotus ostreatus.

  • Nitrogen fixation by legumes can be valuable sources for organic farming. This study was to investigate the effect of different legume mixtures on nitrogen fixation and transfer to grasses on spring paddy field. Three different mixtures were used (rye+hairy vetch, Italian ryegrass+crimson clover, oat+pea) in a randomized complete block design with three replications and sowed in pots with different sowing rate (5:5 rye:hairy vetch,7:3=Italian:crimson, 6:4=oat:pea) on early March. $(^{15}NH_4)SO_4$ solution at. 99.8 atom%$^{15}N$ was applied to the each pot at the rate of 2kg N $ha^{-1}$ on $16^{th}$ April. Forage were harvested at ground level in heading stage and separated into legume and grass. Total N content and $^{15}N$ value were determined using a continuous flow stable isotope ratio mass spectrometry. DM yield of rye+vetch, Italian+crimson and oat+pea were 6,607, 3,213 and 4,312kg/ha, respectively. Proportion of N from fixation was 0.73(rye+vetch), 0.42(Italian+crimson) and 0.93(oat+pea). The percentages of N transfer from legume to grass were from 61% to 24% in different method by treatments and -35% to 21% in isotope dilution method.

  • This field experiment was undertaken to find out the effect of grazing and cutting management on the forage quality and soil hardness at different legumes sown swards of the experimental field of Livestock Experiment Station in Suweon, from August 1985 to October 1988. The results obtained are as follows: 1. Crude protein, crude fat and ash contents under grazing were higher than these under cutting, but showed the reverse results in crude fiber and nitrogen free extracts contents. Average in vitro dry matter digestibility (IVDMD) under grazing (72 %) was a little higher than that under cutting (71 %). On the other hand, there was little difference among the mixtures swards in mineral contents and IVDMD. 2. The contents of Ca, P and Mg were a little high in the cutting, but K and Na contents were in gazing. Ca: P ratio in grazing (2.97) was slightly higher than that of cutting (2.94). 3. Production of energies(TDN, StE and NEL) with cutting were appeard to increase by 19.4 %, 13.5 %and 19.0 % than those of grazing, respectively. Mixtures swards including alfalfa showed more production both grazing and cutting. 4. Soil hardness in the top lOcm of soil by cattle grazing was changed from 15.5mm at startihg year to 22.6 mm after 3 years, but in cutting slightly increase from 15.5mm to 16.2mm. Generally it was low in early spring and high in autumn.

  • Plasma levels of lipids were observed in vegetarians and non-vegetarians in order compare the values between the two groups with different dietary habits, and among different age groups. All 162 vegetarians and 95 non-vegetarians were selected for this study. In detail, male vegetarians subjects were devided into three groups according to their ages, 20's, 30's and 40's. And three control groups were also selected at matching basis. Two groups each were selected for female subjects in their 20's and 40's. All ten groups were adopted and the lipids levels were compared appropriately. Dietary habits of vegetarians were shown to be fairly strict. They consumed almost no animal foods and depended largely upon plant foods with emphasis on unrefined cereals and legumes. on the other hand, non-vegetarians consumed meats, fish egg and milk frequently. Most of plasma lipid levels measured were found to be lower in vegetarians and tended to be higher for the higher age groups of both vegetarians and non-vegetarians. Although the lipids levels of non-vegetarians were higher than the ones for vegetarians, the levels were within optimal range, and it can be concluded in this study that the plasma lipid levels of non-vegetarians under Korean dietary pattern are quite acceptable.

  • This experiment was carried out to study the effect of pure nitrogen fertilization on botanical composition of grassland in 1987~ 1988 under practical conditions at the " Federal Institute for Agriculture in the Alps" in Austria. The application rates were 0, 30, 60, 90 and 120kg/ha/cut, the cutting regimes 3-, 4 , 5- and 6-cuts/year. The results were as follows: 1. Only PK fertilization resulted in higher botanical composition of Trifolium repens among legumes in grassland, which was increased by cutting frequency .2. Nitrogen fertilization on three-cut areas resulted in higher existence of generally valuable tall grasses such as Arrhenotherum elatius Trisetum flavescens and Dactylis glomerata . On the other hand, nitrogen fertilization on four-, five- and six-cut areas showed mainly Doctylis glomerato and Poa pratensis appearance. 3.For some cases, appearance of less valuable grasses, herbs and weeds such as Agropyron repens, Poa trivialis, Poa annua, Setoria viridis, Aegopodium podagra rio, Men landrium rubrum, Taraxacum officlnale, Achillea millefolium, Rorippa sylvestris and Polygonum ocleulare was *Bundesanstalt fur alpenlandische Landwirtschaft Gumpenstein(A-8952 Irdning, 6sterreich) increased on medium and high rates of N fertilized areas. 4.Reduction of sward density may also diminish the advantages of nitrogen fertilization and may be threatened by mainly high dressings of nitrogen combined with too late utilization of the sward. 5.Location altered the efficiency of nitrogen fertilization on botanical composition.mposition.
