Purpose: For dissecting the possible benefits and usages of Cheonggukjang, five different beans, soybean, black soybean, red bean, chickpea, and lentil bean, underwent the fermentation process along with Bacillus subtilis. Methods: Resultant Cheonggukjang physicochemical and sensory properties such as pH, amino type nitrogen, slime contents, rheological properties, and sensory strength and consumer acceptance were analyzed. Results: Values of pH were found to be highest in Cheonggukjang made with soybean (SC), followed by Cheonggukjang made with black bean (BSC) and Cheonggukjang made with red bean and soybean mixture (RBSC), and lastly Cheonggukjang made with chickpea (CBC) and lentil bean (LBC). Amino type nitrogen values were shown to be highest in SC with a value of $394.74{\pm}28.80mg%$, subsequently were values taken from RBSC, followed by BSC, CBC, and lastly LBC. Slime contents were the highest in SC with a value of $3.44{\pm}0.36%$, with RBSC, BSC, CBC, and LBC without statistical difference. Total colony count was found to show higher value in BSC, SC, and RBSC, in contrast to the lower values found in CBC and LBC. Color was shown to be lightest in CBC and with darker shades shown that of SC, LBC, RBSC, and BSC in descending order. In rheological properties, hardness, adhesiveness, and viscosity were found to be highest in SC. Sensory strength analysis and sticky appearance were highest in SC, with fermented odor being lowest in CBC and BSC. The strength of sweetness, sourness, and umami taste did not show statistical difference, however, bitterness was shown to be highest in LBC and lowest in CBC, SC, and BSC. In the consumer acceptance test, overall acceptance was highest in SC and CBC. Conclusion: In conclusion, SC was found to be the best bean variety for making Cheonggukjang fermented with Bacillus subtilis, however, CBC may act as an alternative for manufacture of Cheonggukjang resulting in sound consumer acceptance.

This study was carried out for investigation of morphological characteristics and for analysis of the relationships between morphological indices and proximate compositions of the recommended soybean varieties in Korea. The weight of 100 seeds and weight percentages of seed coat and germ to the whole soybean of 19 varieties were ranged from 12.28 to 25.54g, from 6.02 to 8.29% and from 1.66 to 3.35%, respectively. The average long and short widths and length were $5.95{\sim}7.59mm,\;5.03{\sim}6.95mm\;and\;6.44{\sim}8.38mm$, respectively. The Hunter b values(yellowness) ranged from 15.9 to 21.7 for seed coat and from 17.7 to 23.1 for cotyledon. From the statistical analysis, a strong positive correlation(r>0.97) existed between total weight and cotyledon weight and long width, and between cotyledon weight and long width. Protein content had low correlations(r<0.48) with total weight, cotyledon weight, length and long width.

Since there have been no method which can applicable to the screening of commercial sesame oil adulterated with other vegetable oils, the present investigation was carried out particularily focusing on the the pattern of IN absorption of sesame oil and other vegetable oils. For this, a variety of oil samples prepared by the conventional method from sesame seeds, perilla seeds, com, soybean, and rice bran were analyzed by IN spectrophotometer. IN spectra of sesame oil and oil of unheated sesame seeds showed absorption peaks at 215, 230 and 290 nm. While UV spectra of com oil, perilla oil and soybean oil all showed absorption peaks at 215, 230 and 280 nm, that of rice bran oill showed peaks at 215, 290 320 nm. When sesame oil was mixed with com oil, perilla oil or soybean oil, respectively, from which the absorbance of peaks at 290 nm were lower than pure sesame oil. The peak at 320 nm which was typical absorption peak of rice bran oil was still observed in the spectnun of mixture of sesame oil with rice bran oil.

A soybean variety KWANG KYO was planted on the hilly land and fertile soil, and concentrated superphosphate and fused phosphate were applied on calcium hydroxide treated soil at level of 2.5%, 5% and 7.5% of phosphate absorbtion coefficient of soil. Application of phosphate fertilizer and lime caused higher grain yield in hilly land soil than fertile soil. The effect of fused phosphate on soybean yield was superior to concentrated superphosphate, and the effect of lime on fused phosphate availability was not significant. When the two phosphate sources were compared at equal $P_2O_5$ basis, fused phosphate required higher amount than concentrated super-phosphate. Negative correlation was obtained between potassium content and Ca + Mg in soybean leaf and in soil respectively.

This study was conducted to investigate the effects of benomyl application at different growth stages on the infection of green pod and seed by Phomopsis spp. and yield in vegetable soybean. One early maturing vegetable soybean variety 'Seokryangputkong' was planted on 20 April at Suwon in 1996. The rate of non-infected green pods by Phomopsis spp. was most highly suppressed by benomyl application once at the R5 stage and twice at R4 and R6 stages. The rate of non-infected green pods was higher in branches than in mainstem, and in upper than in low part of plant. The Phomopsis seed decay at maturity was most highly decreased by benomyl application once at the R6 stage and twice at the R4 and R6 stages. Benomyl application effectively reduced the infection rate of green pod and seeds by Phomopsis spp. and increased the yield of non-infected green pods by 34∼76％ and non-infected seeds by 51∼98％.

To study the effects of planting dates and mulching on the growth and yield of summer type soybean, a variety, Damamidori introduced from Japan, was planted four times from April 13 with 10 days interval. Experimental plot in each planting date was devided into two sub-plots, polyethylene film mulching and non-mulching. By mulching, days to emergence and first flowering were shortened, especially in the early plantings; e.g. as much as 11 and 12 days, respectively, in the first planting. Compared to non-mulching, plant height, number of nodes of main stem, number of branches, and dry weight of stem and branches per unit area were also much increased by mulching. As the plantings were delayed, plant height, the total number of nodes and dry weight of main stem and branches, and 100 seed weight showed increasing trends, which were mainly due to lower infection rate of soybean seeds to pod and stem blight (Diaporthe phaseolorum) in the later plantings. The higher infection rate of soybean seeds to pod and stem blight, the lower infection rate to purple seed stain (Cercospora kikuchii) was shown in mulching but not in non-mulching.

The Merit variety of soybean (Glycine max L.), harvested in 1971 was germinated in the dark at $21{\sim}25^{\circ}C$ for days. The soybean sprouts were divided into cotyledons and seedling axis (=hypocotlyplus root) and subjected to the determination of dry weight, crude fat content and lipid components (esterified sterols, triglycerides, free fatty acids, free sterols and phospholipids) at two-day intervals during the germination periods. The results are summarized as follows: 1) During the germination period, the dry weight and crude fat content in cotyledons decreased continuously, but the dry weight seedling axis increased continuously and crude fat content remained almost constent. 2) The triglyceride content in crude fat from cotyledons decreased and free fatty acid content increased continuously, but triglyceride content in crude fat from seedling axis showed no change until 6th day and increased slightly after 8th day, and free fatty acid content showed increase after 4th day and decrease after 6th day. Phospholipids, free and esterified sterols content in cotyledons increased continuously, but their content in seedling axis remained unchanged.

Contents of soyasaponin group B were compared according to two regions and ten varieties by HPLC. Those compounds were known to be beneficial for health. After soyasaponins were isolated and identified, those isolated compounds were used for HPLC analysis. The contents of soyasaponin were very different by regions but highest in the soybean with black seed coat. It was appeared that environmental difference for soybean growth could strongly change of soyasaponin contents.

This study was conducted to examined the effects of TIBA and ethrel on podding rate, percentage of seed numbers per pod, and seed yield of black soybean. The black soybean variety “Geomjeongkong 1” was used. TIBA of 50, 100, and 150 ppm and ethrel of 500, 1,000, and 1,500 ppm were applied at V6 (fifth leaf stage), V8 (seventh leaf stage), and R1 (flowering stage). The podding rate was increased by the treatment of TIBA at R1 stage while it was decreased by ethrel at all growth stages. Compared with control, TIBA decreased 100 seed weight a little bit but ethrel increased it slightly, on the contrary. Both TIBA of 50 ppm and ethrel of 500 ppm increased the sued yield by 8 to 28％ compared with control regardless of growth stages of application; the highest seed yield was obtained at V6 stage of application of 50 ppm in TIBA and 500 ppm in ethrel, respectively.
