This study was conducted to select the most suitable dye bath soil of mat rush for good quality. Dry stem weight ranged from 102.5 to 107.0 g, dry stem ratio ranged from 34 to 36%, color of stem ranged from soft gray to heavy gray, degree of softness ranged from high to low and degree of floating ranged from extremely high to low. All the good quality components, such as dry stem weight, dry stem ratio, color of stem, degree of softness and degree of floating showed large variations. Hadong white ceramic soil, the superior dye bath soil of mat rush, showed relatively superior values for all the good quality components with 102.5 g in light dry stem weight, 34% in high dry stem ratio, good color of soft gray in color stem, high in degree of softness and extremely high id degree of floating. The results indicate that dye bath soils shows different adaptabilities to a particular dye bath and Hadong white ceramic soil seems to be the most suitable dye bath soil of mat rush for good quality.

In order to find out the optimum fertilizer level and planting density of high yielding variety, $Okayma^{#2}$, this experiment was conducted with 3 compositions of fertilizer levels and a different plant density at the experiment paddy field of mat rush in Mokpo Experiment Station, National Institute of Crop Science, RDA. $Okayma^{#2}$, mat rush variety was grown under different fertilizer level and planting density with the highest yielding. Yield components such as stem length, number of stem were highest at the plots with fertilizer level (kg/10a), 80-20-40 and planting density, 20 ${\times}$ 10cm. Judging from the results reported above, at optimum fertilizer level and planting density of mat rush seemed to be 80-20-40kg/10a fertilizer and 20cm row spacing and l0cm or I5cm planting spacing.

This study was conducted to select the most suitable fertilizer level on nursery of mat rush for good quality and high yield. $N-P_{2}O_{5}-K_{2}O=60-30-60$ (kg/10a), fertilizer level on nursery of mat rush showed relatively superior values for all yield components and quality with 57g in fresh weight, 12g in dry weight, 23% in air drying ratio for per plant at the nursery and 125cm in stem length, 150 numbers in stem number, 4,082kg/10a in fresh stem yield, 345kg/10a in long stem yield, 996kg/10a in medium stem yield, 1,421kg/l0a in total stem yield, 34% in dry stem ratio and 30% in long stem ratio at the main paddy field. The results indicate that fertilizer level, $N-P_{2}O_{5}-K_{2}O=60-30-60kg/10a$ in nursery shows different adaptabilities to a particular fertilizer level and 60-30-60 (kg/10a) seems to be the most suitable fertilizer level of mat rush for good quality and high yield.

In order to find out the optimum transplanting date of mat rush, this study was investigated ecological characters, yield components and yield of three varieties (Okayama#2, Sajanami and Sedo #4) at 5 transplanting dates(October 25, November 5, November 15, November 25 and March 5). As transplanting date was delayed, the flowering date and maturing date was delayed also and stem length was longest in October 25 transplanting but it grew short in the late transplanting. Number of stems per plant was increased most in October 25 transplanting, that is, increased to 143 in okayama#2, 138 in Sedo#4 and 135 in Sajanami, and it was decreased in the late transplanting. Fresh stem yield and dry stem yield were heaviest in October 25 transplanting, and it was light in the late transplanting. Judging from the results reported above, in optimum transplanting date of mat rush seemed to be before the October 25.

Researches on industrial crops in Korea before 1962 were concentrated on fiber crops such as cotton, kenaf, hemp, ramie and flax. Then research works on oil crops, sugar crops and other high income crops were followed. However, no land is shared for the production of kenaf, flax, sugar beet, sweet sorghum and sunflower at present in Korea, while the cultivation of cotton, hemp, ramie and mat rush is decreasing continuously to the marginal point. At present researches are emphasized on oil crops such as seasame, peanut and perilla and high income medicinal herbs of which cultivating acreages are increasing. Numerous varieties were released as a result of active breeding works on industrial crops since 1962, i.e. 3 sesame varieties including "Suweon 21", 3 peanut varieties including "Seoduntangkong", and 6 rape varieties including "Yudal" in oil crops, one cotton variety "Mokpo 7", one hemp variety "MS4-1", and one kenaf variety "Suweon 2" in fiber crops, and two stevia varieties "Suweon 2" and "Suweon II" in sugar crops. Quality improvement of rape seeds and development of hybrid rapes utilizing male sterile lines are the most significant results of breeding works, while the establishment of vinyl mulching cultivation of sesame and peanut are the most successful results in agronomic researches during the last 20 years.re the most successful results in agronomic researches during the last 20 years.

Sleeping is important for human being in that it has a great effect on their daily activities. Considering that an average adult sleeps seven to eight hours a third of our life is spent in bed. The present study intends to make consumers aware of the important of the bedding science and help the manufactures develop efficient, up-to-date beds. For these two purposes, consumers' recognitions and opinions on the features of the bedding were surveyed. In the study, a questionnaire consisting of various items on the features of the bedding was designed and distributed to consumers in 8 regions & Taegu in Korea to survey the patterns in which they buy, use, and maintain their bedding. The result of the study are as follows; Air conditioner is widely used popular because of hot weather in Taegu. People in Taegu mostly purchase their bedding from market, in every 5~6 years. The important point to be considered for bedding purchases were humidity absorption, air permeability, light weight in summer comforters, thermal insulation, flexibility, color figure design in winter comforters, humidity absorption, flexibility, color figure design in mats. As summer bedding, a sheet of single-layer quilt and rush mat were most popular which indicates climate of hot and humid weather in Taegu. Bedding uses in winter were in order a sheet of cotton, silk, wool quilt, and silk quilt showed high level in contrast to other areas. Dissatisfactions with summer quilts were humidity absorption, air permeability, heaviness and in winter quilts they were dissatisfied with thermal insulation, heaviness, flattening. In details about bedding managements, people in Taegu most frequently disinfected their bedding by sunlight in one month, and refinished every 5 years.
