This experiment was conducted to select optimum minor cereal crop and variety for the marginal agricultural lands so that they would be used to increase the agricultural land use rate in mountainous areas. This experiment used three different marginal agricultural lands, that is, slope land, barren land and gravelly land. Soil pH of control field was 7.85, slightly alkali, whereas gravelly land showed strong acid(pH 5.1). EC of marginal agricultural lands was generally lower compared to the control, especially barren land showed 0.05dS m-1 which was the lowest among marginal agricultural lands. Foxtail millet showed no significant difference of heading and ripening date among marginal agricultural lands. Foxtail millet of slope land showed the highest culm length(169.5 cm) and grains per ear(4913.9 grains) among marginal agricultural lands except control field. Growth duration of three varieties was varied from 112 to 113days, which was not different statistically. In grains per ear of common millet, slope land showed 787.1 grains which was the highest among marginal agricultural lands except control field. Among varieties, Byorukgijang showed the highest grains per ear(827.2 g/ear), whereas 1000 grain weight was 5.5 g which was lower compared to that of Hwanggijang(6.2 g). In sorghum, slope land showed the highest grains(2563.8 grains) per ear and ears per 3.3 m2 (26.0 ears) except control field. Growth duration of three sorghum varieties almost the same from 122 to 123 days, whereas the highest grains per ear was obtained from Moktaksusu(2357.6 grains). Jangmoksusu showed the highest 1000 grain weight(23.8 g) among three sorghum varieties. In yield of three foxtail millets, the highest yield was obtained from slope land(282.0 kg/10a) among marginal agricultural lands and Mongdangjo showed the highest yield(252.3 kg/10a) among three varieties. In yield of three common millets, the highest yield was obtained from slope land(196.0 kg/10a) among marginal agricultural lands and Byorukgijang showed the highest yield(173.8 kg/10a) in three varieties. In three sorghum varieties, the highest yield was obtained from slope land(301.7 kg/10a) among marginal agricultural lands and Moktaksusu showed the highest yield(236.5 kg/10a) among three varieties.

The subject of this experiment is to supply basic data to inhibit non-productive tillers which are uneconomical for mechanical harvesting and to evaluate optimum planting density and sowing date in central district. Total number of tillers and effective first and second of tillers according to different planting density was higher in 80 ㎝ ridge than 60 ㎝ ridge in proso millet. The wider between plant distance on the ridge, the more increased total number of tillers and effective first and second of tillers. The highest effective tillers (91.7 %) in the first tillers was obtained from the second sowing date (23 May) among different sowing date and next is in the order of 3 rd (13 June, 89.8%) > 1 st (2 May, 85.6%) > 4 th (4 July, 85.2%). The percentage of effective tillers in the second tillers was decreased in the order of 2 May (53.7%), 23 May (40.7%), 13 June (22.2%), 4 July (0%) as the sowing date was delayed. There was no significant difference in days to heading and days to ripening according to different planting density. Although culm length was increased as planting density was increased, whereas number of tillers, stem diameter, ear length, grains per ear and 1000 grain weight was decreased. In the growth and yield characteristics of proso millet according to different sowing date, days to heading and days to ripening, culm length, stem diameter, ear length, grains per ear and yield per 10a were decreased. After the sowing date of 13 June, the reduction of growth and yield characteristics were higher because of excess-moisture injury.

윤성탁,김선오 단국대학교 1997 論文集 Vol.31 No.-

The germination of major medicinal crops cultivated widely in our country is poor compared to the other food crops. Causes of poor germination and emergence were reported to be the dormancy of seed and physiologically immature embryo and so on. The problem of this poor germination interfere with the mass production of medicinal crops. This experiment was conducted to study the germination characteristics, e.g. germination percentage, germination vigor, average days to germination and germination coefficient, in three medicinal crops, Ledebouriella seseloides WOLFF., Glehnia littoralis FR. SCHMIDT. and Angelica acutiloba "KITANGWA. Also the aim of this experiment was to clarify the response of germination to temperature, light and plant growth hormones. The results obtained were summerized as follows. 1. The germination percentage, germination vigor and germination coefficient of three medicinal crops showed relatively high value at 20℃ of incubation temperature, which is not preferable to high temperature in germination. 2. The effects of light treatment on seed germination characteristics were not recognized, which is not thought to be light sensitive seed. 3. The teatments of plant growth hormones promoted the germination characteristics, germination percentage, germination vigor, average days to germination and germination coefficient, so that the effects of plant growth hormones was clear compared to the control. 4. among three crop species, the germination of Ledebouriella seseloides WOLFF, and Glehnia littoralis FR. SCHMIDT. was relatively higher than that of Angelica acutilobaKITAGAWA. in four germination characteristics.
